Taxonomic revision of the Neotropical genus Argentinomyia Lynch-Arribálzaga, 1891 (Diptera: Syrphidae), with description of 16 new species.

The Neotropical flower fly genus Argentinomyia Lynch-Arribálzaga (Diptera: Syrphidae) is revised and rediagnosed. An updated key to the Neotropical genera of Bacchini and Melanostomini is provided. As a result of the ongoing systematic study of the genus, sixteen new species were discovered and described: Argentinomyia aurifacies Montoya & Thompson sp. nov. (Dominican Republic), Argentinomyia belmira Montoya & Wolff sp. nov. (Colombia), Argentinomyia humboldti Montoya & Wolff sp. nov. (Colombia and Ecuador), Argentinomyia ivani Montoya sp. nov. (Colombia), Argentinomyia jalcaensis Thompson & Montoya sp. nov. (Perú), Argentinomyia jamaicensis Montoya sp. nov. (Jamaica), Argentinomyia norrbomi Montoya sp. nov. (Brazil), Argentinomyia occidentalis Montoya & Wolff sp. nov. (Colombia), Argentinomyia plaumanni Thompson & Montoya sp. nov. (Brazil), Argentinomyia sagoti Montoya sp. nov. (Mexico), Argentinomyia serendipia Montoya sp. nov. (Colombia), Argentinomyia spinifemorata Montoya sp. nov. (Colombia), Argentinomyia taina Montoya & Thompson sp. nov. (Dominican Republic), Argentinomyia teresae Montoya sp. nov. (Colombia), Argentinomyia transversalis Montoya sp. nov. (Colombia and Bolivia) and Argentinomyia tropandeana Montoya sp. nov. (Colombia, Ecuador and Perú). Five new synonyms are proposed for four species: Melanostoma melanocerum (Williston, 1891) = Argentinomyia catabomba (Williston, 1891), Braziliana columbiana (Enderlein, 1935) = Argentinomyia fastigata (Fluke, 1945), Braziliana peruviana (Shannon, 1927), Braziliana thiemei (Enderlein, 1935) = Argentinomyia longicornis (Walker, 1836) and Rhysops funerea (Hull, 1949) = Argentinomyia nigrans (Fluke, 1945). Lectotypes are designated for the following names: Melanostoma catabombum Williston, 1891, Melanostoma crenulatum Williston, 1891, Melanostoma longicornis Williston, 1888, Melanostoma melanocerum Williston, 1891 and Pipiza longicornis Walker, 1836. Twenty-six species are redescribed and an updated key proposed for 41 out of the 47 species recognized as valid. Synonyms, descriptions, comparative diagnosis, high-definition color photographs of overall appearance, illustrations of the male genitalia as well as field photographs are provided. The known distribution ranges are mapped and the biogeographical affinity and endemism are discussed. Female genitalia are described for the first time for the genus. Argentinomyia berthae (Lima, 1946) is rediscovered and redescribed, including the designation of a neotype. The taxonomic status of Argentinomyia scitula (Williston, 1888) is considered doubtful and needs further study. Taxonomic notes are provided for Argentinomyia aenea (Willistoni, 1891) and A. huitepecensis Montoya, 2020. The high diversity, the biogeographical affinities, the noteworthy endemism patterns, new country records as well as the morphological variation evidenced in the present revision suggest that the genus is much more diverse than it appears, with many new species that undoubtedly remain to be described from unexplored areas of the Neotropics. Our study provides a thorough morphological assessment as well as the updated biogeographical distribution, which constitute a starting point to answer questions and propose hypotheses about the phylogenetic relationships, historical biogeography, diversification patterns and conservation of Argentinomyia in forthcoming contributions.

Review of the endemic Neotropical genus Agenamyia Albuquerque (Diptera: Muscidae) with the description of new species from South America.

Agenamyia Albuquerque, an endemic neotropical genus with two species, has been revised to include three new species: Agenamyia colombiana de Carvalho, Wolff & Fogaa sp. nov. from Envigado; Agenamyia maculata de Carvalho, Wolff & Fogaa sp. nov. from El Retiro; and Agenamyia timida de Carvalho, Wolff & Fogaa sp. nov. from Sopetrn, all localities in Antioquia, Colombia. This review presents an identification key for all species, including color images and illustrations of male and female terminalia. The distribution of all species is mapped and discussed.

Two new species of Ptecticus Loew, 1855 (Diptera: Stratiomyidae), from bat guano in a Colombian cave.

Genus Ptecticus is widespread distributed in the world, in the Neotropics 51 species have been documented and only four are recorded in Colombia so far. Herein we describe two new species, Ptecticus benecki sp. nov. and Ptecticus pseudospatulatus sp. nov. reared from bat guano in the Colombian Andes. This study contributes to the species richness in the region, ecological records and natural history for the family.

New carrion-visiting flesh flies (Diptera: Sarcophagidae) from tropical dry forests of Colombia and their phylogenetic affinities.

Many flesh flies of the subfamily Sarcophaginae are very competitive carrion visitors and breeders, and several are synanthropic species of medical and forensic importance. The knowledge of these taxa is still limited, which is more noticeable in sub-sampled ecosystems such as the tropical dry forests of Colombia. Four new species, Blaesoxipha (Gigantotheca) wajiira sp. nov., Lepidodexia deborarangoa sp. nov., Oxysarcodexia luriza sp. nov. and Udamopyga iku sp. nov., are described from tropical dry forests in the Colombian departments of Atlántico, Bolívar, Cesar and La Guajira, all collected using Van Someren-Rydon traps baited separately with fermented fruit, decomposing fish and human feces. The species B. (G.) wajiira sp. nov. is probably synanthropic, while the remaining three new species avoid habitats in and around built-up areas. A phylogenetic parsimony analysis based on 222 morphological characters across 121 taxa of flesh flies recovers each new species nested within their respective genus. The subgeneric affiliation of L. deborarangoa sp. nov. within the large and diverse genus Lepidodexia (sensu lato) is inconclusive, and potential issues of relying solely on external morphological characters for generic and subgeneric classifications are highlighted. The species Lepidodexia (Notochaeta) woodi (Lopes), Oxyvinia wicharti (Lopes) and Sarcofahrtiopsis spinetta Mulieri & Dufek are new records for Colombia. COI sequence data are provided for U. iku sp. nov., L. (N.) woodi and O. wicharti.

Four new Neotropical species of Eudicrana Loew (Diptera, Mycetophilidae, Sciophilinae) from the Colombian high Andean ecosystems, with comments on the genus.

Four new species of the sciophiline genus Eudicrana Loew are described for the Eastern and Central Andes of Colombia-Eudicrana silvaandina sp. nov., E. chingaza sp. nov., E. maculata sp. nov. and E. merizaldei. These are the first species of Eudicrana described from the extreme northern range of the Andes. The altitudinal distribution of these species in the paramos and high Andean forest ecosystems is restricted to 1750-3660 m a.s.l. and some other information on the environment is briefly discussed. A key for the Colombian species of Eudicrana is provided and a discussion is elaborated on the position of these species within the genus.

Description of six new large species of Argentinomyia Lynch-Arribálzaga, 1891 and redescription of Talahua fervida (Fluke, 1945) (Diptera, Syrphidae, Syrphinae).

The morphological similarities between five new large Argentinomyia species and Talahua fervida Fluke are characterized and presented. Six new species of Argentinomyia (10-12 mm long) are described: Argentinomyia andina Montoya & Wolff, sp. nov. (Colombia), Argentinomyia choachi Montoya, sp. nov. (Colombia), Argentinomyia quimbaya Montoya & Wolff, sp. nov. (Colombia), Argentinomyia huitepecensis Montoya, sp. nov. (México), Argentinomyia puntarena Montoya, sp. nov. (Costa Rica), and Argentinomyia talamanca Thompson, sp. nov. (Costa Rica). The genus Talahua Fluke is re-diagnosed and, Talahua fervida redescribed. A taxonomic key and a comparison of diagnostic characters are presented. Photographs of head, abdominal and wing maculae patterns, as well as illustrations of male genitalia are provided for species identification.

New record of Blepharicnema splendens (Diptera, Calliphoridae, Luciliini) and range expansion in Caquetá, Colombia

Blepharicnema splendens is a dipteran with occurrence restricted to the Neotropical Andean mountain forests from 1,400 to 2,500 masl. We surveyed the species using Van Someren-Rydon traps with decaying fish as bait in four sites (veredas) in the Eastern Cordillera, in the Municipality of Florencia, Caquetá, Colombia. A total of 221 individuals were collected in the four localities. The Vereda Las Brisas had the highest abundance, with 104 specimens (45.4%), followed by El Vergel, 76 (33.2%), Tarqui, 46 (20.1%) and Los Lirios, 2 (0.9%). The record of this species in the mountainous ecosystems of the Department of Caquetá expands the known distribution of B. splendens and adds to the incipient knowledge on the diversity of Diptera in this region.

Revision of the Neotropical Neuratelia Rondani (Diptera, Mycetophilidae, Sciophilinae): two new species, a new combination, and a new synonym.

We describe two new Neotropical species of Neuratelia Rondani from the high Central Andes of Colombia, N.altoandina sp. nov. and N.colombiana sp. nov. The holotype of Eudicranaelegans Lane actually is a species of Neuratelia and a new combination is proposed. Our examination of the holotype of Neurateliasapaici Lane from southeastern Brazil shows this species to be a synonym of N.elegans (Lane), which is formally proposed here. Neurateliasapaici is redescribed. The position of these three species within the genus is discussed. A key for the Neotropical species of Neuratelia is provided.

New species and new distributional records of Neotropical Mantispidae (Insecta: Neuroptera).

The Neotropical fauna of Mantispidae is currently composed of 106 species. We provide new distributional records of Mantispidae from Colombia and Panama. Three new species are described, one in Symphrasinae from Colombia, and two in Mantispinae from Colombia and Panama. Haematomantispa nubeculosa (Navás, 1933) and Leptomantispa axillaris (Navás, 1908) are reported from Colombia for the first time, the former being the first record of the genus in the country. New locality records for other species previously known from Colombia are also given. For Panama, we report Anchieta fasciatella (Westwood, 1867) and Trichoscelia iridella (Westwood, 1867) for the first time, the former is herein newly transferred from Plega to Anchieta. Three names Mantispa confluens Navás, 1914, n. syn., Buyda apicata Navás, 1926, n. syn., and Mantispa neotropica Navás, 1933, n. syn., are here synonymized with Buyda phthisica (Gerstaecker, 1885). Updated keys for the genera of Mantispinae, and species of genera Trichoscelia, Buyda, and Climaciella from Colombia are included. With this new information, the known species richness of Mantispidae from Colombia increases from 21 to 26, and from 16 to 19 species in Panama.

Insects of forensic importance associated to cadaveric decomposition in a rural area of the Andean Amazon, Caquetá, Colombia / Insetos de importância forense associados à decomposição cadavérica em uma área rural na Amazônia Andina, Caquetá, Colômbia

ABSTRACT Forensic entomology is a frequently used tool to estimate the time interval between death and the discovery of the corpse. Succession of arthropods associated with cadaveric decomposition was monitored in a rural area of the Municipality of Florencia, Department of Caquetá, Colombia. Three pigs (Sus scrofa) were used as study models. Insect sampling, and monitoring of carcasses and environmental conditions were carried out every five hours. The total time from death to skeletonization was of 545 hours (22.7 days). A total of 30833 insect individuals were collected. Specimens were distributed in nine orders, 46 families, 95 genera and 106 species. Diptera was the most abundant, with 23215 individuals (75.3%), followed by Coleoptera, with 3711 individuals (12%), and Hymenoptera, with 3154 individuals (10.2%). Immature stages of Cochliomyia macellaria, Chrysomya albiceps, Hemilucilia semidiaphana and Ophyra aenescens were the main species involved in tissue consumption and acceleration of the decomposition process. Due to the presence of ants Cheliomyrmex sp., Camponotus sp. and Dinoponera sp., and coleopterans Hister sp., Acylophorus sp. and Philonthus spp., it was not possible to obtain sufficient Diptera egg masses for rearing the colonizing species. These results can be used as a standard to determine the postmortem interval in criminal investigations in the rural area of the Andean Amazon, Caquetá, Colombia.

RESUMO A entomologia forense é uma ferramenta frequentemente utilizada para estimar o intervalo de tempo entre a morte e a descoberta do corpo. Na área rural do município de Florencia, Caquetá, foi monitorada a sucessão de artrópodes associados à decomposição cadavérica, utilizando como modelo de estudo os cadáveres de três porcos (Sus scrofa). A amostragem de insetos e coleta de dados ambientais foram realizadas a cada cinco horas. A duração total do processo desde a morte até a esqueletização foi de 545 horas (22,7 dias). Foram coletados 30833 espécimes de insetos, distribuídos em nove ordens, 46 famílias, 95 gêneros e 106 espécies. Diptera foi o grupo mais representativo, com 23215 indivíduos (75,3%), seguido de Coleoptera, com 3711 indivíduos (12%) e Hymenoptera, com 3154 indivíduos (10,2%). Os estágios imaturos de Cochliomyia macellaria, Chrysomya albiceps, Hemilucilia semidiaphana e Ophyra aenescens foram as principais espécies envolvidas no consumo de tecidos e na aceleração do processo de decomposição. Devido à presença de formigas Cheliomyrmex sp., Camponotus sp. e Dinoponera sp. e de besouros Hister sp., Acylophorus sp. e Philonthus spp., não foi possível obter massas de ovos de Diptera suficientes para a criação de espécies colonizadoras. Nosso estudo fornece subsídios para determinar o intervalo post-mortem em investigações policiais e promover a entomologia forense em uma área rural da Amazônia Andina na Colômbia.

DNA barcoding for identifying synanthropic flesh flies (Diptera, Sarcophagidae) of Colombia.

The first step for a successful use of any insect as indicator in forensic sciences is providing a precise taxonomic identification at species level. Due to morphology-based identification of Sarcophaginae flies (Diptera, Sarcophagidae) is often difficult and requires strong taxonomic expertise, their use as forensic indicators has been limited. Consequently, molecular-based approaches have been accepted as alternative means of identification. Thus, we aimed testing the efficiency of the barcode region of the mitochondrial cytochrome oxidase subunit I (COI) gene for identification of synanthropic flesh flies of several species of the genera Peckia, Oxysarcodexia, Ravinia, and Tricharaea collected in Colombia. The 645-bp fragment of COI was amplified and aligned (215 parsimoniously informative variable sites). We calculated Kimura two-parameter genetic distances and reconstruct a Neighbor-Joining phylogenetic tree. Our Neighbor-Joining tree recovered all species as monophyletic, and confirmed a new species of the genus Ravinia as also indicated by the interspecific genetic divergences and morphological observations. We obtained a 100% of identification success. Thus, the COI barcodes showed efficiency as an alternative mean of identification of species of flesh flies collected on decaying organic matter in Colombia.

Postmortem interval estimation based on Chrysomya albiceps (Diptera, Calliphoridae) in a forensic case in the Andean Amazon, Caquetá, Colombia / Intervalo pós-morte estimado a partir de Chrysomya albiceps (Diptera, Calliphoridae) em um caso forense na Amazônia Andina, Caquetá, Colômbia

This is the first application of forensic entomology in a case involving a human corpse found in the urban area of the Municipality of Florencia, Caquetá, Colombia, in the Piedemont of the Colombian Amazon. Three days after removing the body from the scene, pupae and puparia were collected and identified as Chrysomya albiceps (Wiedemann, 1819) (Diptera, Calliphoridae). The postmortem interval was estimated on the basis of previously published data and verified through accumulated degree hours (ADH) and intrapuparial development. The estimated minimum postmortem interval was of 229 hours (9.5 days).

Esta é a primeira aplicação da entomologia forense em um caso envolvendo um cadáver humano encontrado em uma área urbana do Município de Florencia, Caquetá, Colombia, no Piedemonte da Amazônia Colombiana. Três dias após a remoção do corpo da área, pupas e pupários foram coletados e identificados como Chrysomya albiceps (Wiedemann, 1819) (Diptera, Calliphoridae). O intervalo pós-morte (IPM) foi estimado com base em dados publicados previamente e verificado usando graus-horas acumulados (GHA) e desenvolvimento intrapuparial. O intervalo pós-morte mínimo estimado foi de 229 horas (9.5 dias).

Images of type material, including drawings of male genitalia are provided. An adjustment for the latest identification key for the Quichuana species and distribution maps for those species occurring in Colombia are given.

Intra-puparial development of Lucilia eximia (Diptera, Calliphoridae) / Desenvolvimento Intra-pupal de Lucilia eximia (Diptera: Calliphoridae)

There are few studies about the intra-puparial development in Diptera, nonetheless its importance has been increased because several dipteran species are of forensic interest. Studies on the life cycles of flies often disregard the changes that occur inside the pupae. The objectives of this research were to analyze the intra-puparial development of Lucilia eximia, and to describe chronological and morphological changes that occur during this stage. Around 1.600 specimens were laboratory-reared. The pre-pupae were identified by the reduction of their size and change in coloration, and 10 individuals were sampled every three hours (n=1.000) until adult emergence. The specimens were fixed in 96% alcohol, subsequently immersed in Canoy solution for 24 hours and in formic acid (5%) for 48 hours, to facilitate dissection and analysis of the morphological changes of the individuals. Four stages of the intra-pupal development of L. eximia were observed: 1) Larva-pupa apolysis, which lasted 23 ± 1.08 h; 2) Cryptocephalic pupa, 5 ± 0.53 h; 3) Phanerocephalic pupa, 92 ± 1.94 h; and 4) Pharate adult: Transparents eyes, 125 ± 2.15 h; Yellow eyes, 23 ± 0.89 h; Pink eyes, 14 ± 0.73 h; and Red eyes, 20 ± 0.60 h. The pharate adult is completely formed after 296 hours and the emergence of the adult occurred after 302 ± 3.81 h. In addition, there were included the stage of pre-pupa, pupariation and the beginning of the adult stage, Imago and adult emergence. Each stage is described and compared with those described for Chrysomya albiceps (Calliphoridae).

No mundo existem poucos estudos sobre o desenvolvimento intrapupal de Diptera. Comumente, os estudos dos ciclos de vida das espécies de moscas são feitos eliminando o desenvolvimento embrionário que é muito importante, principalmente nas espécies de interesse forense. O principal objetivo foi o de analisar o desenvolvimento intrapupal de Lucilia eximia, descrevendo as mudanças morfológicas que ocorrem durante o desenvolvimento intrapupal. Foram analisados cerca de 1.600 espécimes cultivados em laboratório. Foram analisadas as fases de pré-pupa, pupa, o início da fase adulta, a imago e a emergência. Pré-pupas foram identificadas de acordo com a redução no tamanho e na alteração da coloração. Dez espécimes foram coletados a cada três horas (n=1.000), sem interrupção, até a emergência dos adultos. As pupas foram fixadas em etanol a 96%. Em seguida foram imersas em solução Carnoy por 24 horas e ácido fórmico a 5% por 48 horas para facilitar a dissecação e análises das alterações morfológicas. Foram determinados 4 estágios de desenvolvimento intrapupal. 1) Apólise larva-pupa com duração de 23 ± 1,08 h; 2) Pupa criptocefálica: 5 ± 0,53 h; 3) Pupa fanerocefálica: 92 ± 1,94 h e; 4) Adulto farado: olhos transparentes: 125 ± 2,15 h; olhos amarelos: 23 ± 0,89 h; olhos róseos: 14 ± 0,73 h e olhos vermelhos 20 ± 0,60 h. O adulto farado estava completo após 296 horas e a emergência dos adultos ocorreu com 302 ± 3,81 h. Cada fase foi descrita e comparada com o descrito para Chrysomya albiceps (Calliphoridae).

Two new species of Huascaromusca Townsend from Colombia, and a new combination for Giovanella carvalhoi (Diptera: Mesembrinellidae).

The Mesembrinellidae (Diptera: Oestroidea) are a group of exclusively Neotropical flies, with 38 recognized species distributed in nine genera. A total of 11 of these species, present in seven genera, were known to occur in Colombia. Huascaromusca obscura Wolff, sp. nov. and H. cordillera Wolff & Ramos-Pastrana, sp. nov. are herein described and their male terminalia are illustrated. Based on a prior molecular study of the family, Giovanella carvalhoi Wolff et al., 2013 is transferred to Huascaromusca Townsend. A key to all known species of Huascaromusca is provided.

The first phylogenetic study of Mesembrinellidae (Diptera: Oestroidea) based on molecular data: clades and congruence with morphological characters.

The Mesembrinellidae (Diptera: Oestroidea) comprise a small group of strictly Neotropical calyptrate flies, with 36 described species. The group has often been treated as a subfamily of Calliphoridae, but there is growing evidence that it corresponds to a distinct Oestroidea lineage. Internal relationships have so far been addressed based only on morphology, with results lacking resolution and support. This is the first molecular phylogeny for the group, which is based on the analyses of 80 terminal taxa (22 mesembrinellid and 28 outgroup species) and 5 molecular markers (ITS2, 28S, COI, COII and 16S). Maximum-parsimony, maximum-likelihood and Bayesian inference methods were used, the latter two with partitioning strategies considering codon position and secondary structure information. Results corroborate the Mesembrinellidae as a monophyletic lineage inside Oestroidea. Three clades were consistently recovered: (1) (Laneella + Mesembrinella patriciae); (2) (Mesembrinella (excluding M. patriciae)  + Eumesembrinella); and (3) (Huascaromusca + Giovanella). Re-examination of the female reproductive tract of M. patriciae revealed a Laneela-type spermatheca, which corroborates the position of the species recovered in the molecular phylogenetic analyses. Mesembrinella and Huascaromusca are in all cases paraphyletic with regards to Eumesembrinella and Giovanella, respectively. These latter two genera should, thus, be seen as subjective junior synonyms.

Its2 para la identificación de califóridos (diptera: calliphoridae) de importancia forense en colombia / ITS2 for the Identification of Calliphoridae (Diptera: Calliphoridae) of Forensic Importance in Colombia

La entomología forense es una disciplina que utiliza insectos para obtener información útil en la determinación del intervalo postmortem (IPM). Las moscas de la familia Calliphoridae son muy utilizadas en entomología forense, sin embargo, su identificación a nivel de especie puede dificultarse cuando el individuo se encuentra incompleto o en estadio inmaduro. En el presente trabajo, se evaluó el potencial de la región ITS2 del genoma nuclear para la identificación de especies de Calliphoridae en Colombia utilizando tres aproximaciones: comparando distancias genéticas utilizando la metodología de códigos de barra, haciendo una reconstrucción filogenética, y con enzimas de restricción (PCR-RFLPs). Se secuenciaron un total de 520 pb en 44 individuos pertenecientes a 16 especies. Se calcularon los valores de distancia intraespecífica e interespecíficas utilizando el modelo K2P. Los valores de distancia intraespecífica oscilaron entre 0 y 0,252 %, mientras que las distancias interespecíficas fluctuaron entre 3,6 y 18,9 %, evidenciándose que esta técnica puede ser utilizada como código de barras genético en la identificación de especies de la familia Calliphoridae. Tanto en los análisis de Neighbour-Joining como en los análisis bayesianos el 90 % de los géneros presentan una monofilia sustentada en probabilidad posterior de 0,89 a 1. En todos los casos la especie Blepharicnema splendens agrupa con el género Lucilia. Con base en las secuencias obtenidas se utilizó la aplicación NEBCutter para identificar cuatro enzimas de restricción las cuales se probaron en el laboratorio y se comprobó su utilidad para la identificación rápida de especies de Calliphoridae en Colombia.

Forensic entomology is a discipline that uses insects to obtain useful information for the determination of the postmortem interval (PMI). Flies of the family Calliphoridae are extensively used for this purpose, however, the identification of these flies can be difficult when the individual is not an adult or when it is incomplete. In the present work, we tested the utility of the ITS2 region of the nuclear genome for the identification of Calliphoridae species in Colombia using three approaches: comparing genetic distances using the barcoding methodology, with a phylogenetic reconstruction, and with PCR-RFLPs. We sequenced 520 bp in 44 individuals belonging to 16 species of califorids. Intraspecific and interspecific distance values were calculated using the K2P model. The intraspecific distance values ranged between 0 and 0.252 %, while the interspecific distance values ranged between 3.6 and 18.9 %, indicating that this gene can be used as a genetic barcode for the identification of species of the Calliphoridae family. Both the Neighbour-Joining and Bayesian analyses recovered 90 % of the genera as monophyletic, with pp values between 0.89 and 1. Blepharicnema splendens was always recovered within the Lucilia genera. Based on the obtained sequences we used the NEBCutter application to identify four restriction enzymes that cut in a differential way and generated useful patterns for the identification of the species. The enzymes were successfully tested and confirmed the utility of this technique as a fast way to identify species of Calliphoridae in Colombia.
