A New Genus of Villini (Diptera: Bombyliidae: Anthracinae) from the Semiarid Caatinga Domain, with a Description of a New Species, Pupal Case, Bionomic Remarks and an Identification Key to the Brazilian Genera of the Tribe.

A new monotypic genus is described and illustrated based on the species Pugliesemyia titiznana gen. nov. et sp. nov. from the Caatinga domains of the state of Pernambuco, Brazil. It belongs to the small group of genera in the Neotropical region (Stonyx Osten Sacken, Lepidanthrax Osten Sacken, Rhynchanthrax Painter) among the tribe Villini, with a projecting proboscis. In addition, we also provide an updated identification key to the known Brazilian genera of Villini, description and illustrations of the pupal case, bionomic remarks on the feeding habits and the host record of the species and a brief discussion on Villini systematics and boundaries of their genera.

Improving the DNA Barcode Library of Mosquito Species With New Identifications and Discoveries in North-Central Argentina.

The family Culicidae is represented by 244 species in Argentina, many of them with epidemiological importance. DNA barcodes are effective tools for identifying mosquito species, for knowing genetic variability, and for establishing phylogenetic relationships. This work aims to explore mosquito diversity employing different species delimitation approaches and to establish formally a DNA barcode library for the Argentinian mosquito fauna. Barcode fragments of 80 specimens of Argentinian mosquitoes of 28 species of the genera Aedeomyia Theobald (Diptera: Culicidae), Anopheles Meigen (Diptera: Culicidae), Coquillettidia Dyar (Diptera: Culicidae), Culex L. (Diptera: Culicidae), Haemagogus Williston (Diptera: Culicidae), Mansonia Blanchard (Diptera: Culicidae), Nyssorhynchus Blanchard (Diptera: Culicidae), Ochlerotatus Lynch-Arribálzaga (Diptera: Culicidae), Psorophora Robinneau-Desvoidy (Diptera: Culicidae) and Uranotaenia Lynch-Arribálzaga (Diptera: Culicidae) were sequenced. Another 82 sequences were obtained from public databases to establish the phylogenetic relationships using Maximum Likelihood and Bayesian Inference, and the species boundaries based on three approaches (ABGD, GMYC, and mPTP). Sixteen of the 28 species sequenced were recovered as monophyletic, of which 12 were also recognized as molecular operational taxonomic units according to the three methodologies. The disparity between morphology and barcode-based identifications could be explained by synonymy, species complexes occurrence, hybridization, incomplete lineage sorting, or the effect of the geographical scale of sampling. Twenty of the 28 sequenced species are new barcodes for Argentina and 11 are the first for science. This increases from 31 to 52 (12.7 to 21.31%) and from six to 10 (28.57 to 47.62%) the number of species and genera, respectively, with barcode sequences in Argentina. New species records are provided.

Description of the immature stages of the flea beetle Omophoita personata (Coleoptera: Chrysomelidae: Galerucinae: Alticini)

Alticini is the most diverse tribe of Chrysomelidae with approximately 8,000 species. Despite of its high diversity, little is known about their natural history and immature stages. Herein, we describe the immatures of Omophoita personata (Illiger, 1807) reared in laboratory from adults sampled in field. We also investigated and compared with immatures of O. octoguttata (Fabricius, 1775). Detailed morphology and chaetotaxy are presented. Larvae of O. personata have their bodies covered with tubercles and the stemmata are absent. These characteristics are shared with other Oedionychina species, reinforcing the stability of these morphological characteristics as diagnostic of this subtribe. This study provides important descriptive and comparative data that increases the knowledge about Alticini immatures.(AU)

Efficient Monitoring of Adult and Immature Mosquitoes Through Metabarcoding of Bulk Samples: A Case Study for Non-Model Culicids With Unique Ecologies.

The rapid and economical monitoring of mosquitos is imperative to understanding the dynamics of both disease vectors and nuisance species. In light of technological advances in mosquito sampling and DNA sequencing, health agencies can now utilize the full potential of metabarcoding pipelines for rapid and standardizable surveillance. Here, we describe mosquito spatial and temporal variation, with particular focus on Mansonia Blanchard species, in the Madeira (Rondônia State) and the Ribeira (São Paulo) watersheds, Brazil using metabarcoding of the D2 rDNA marker. Sampling and molecular pipelines were used to evaluate the taxonomic contribution of mosquitos in pools of culicids collected en masse from macrophyte-roots (immatures) and from Mosquito Magnet traps and protected human landings (adults). Results for adult captures are comparable to morphological diagnoses and clarify previously unknown temporal and spatial species turnover. Metabarcoding of immature stages also confirmed the extent of the geographical distribution of some species and each taxon's association with macrophyte species. Given the benefits of metabarcoding, such as taxonomic acuity, high throughput processing, and objectivity, we suggest such techniques should be more fully incorporated into culicid monitoring schemes. The metabarcoding protocol described herein paired with standardized field sampling schemes, when used by mosquito monitoring professionals, offers substantial improvements in terms of practicality, speed and cost.

Description of the puparium and adult genitalia of Dactylodeictes brevifacies James, 1974 (Diptera: Stratiomyidae)

The puparium of Dactylodeictes brevifacies was described based on fifty-eight specimens reared in laboratory until the emergence of adults. Larvae were collected under the bark of fallen trees in a Cerrado vegetation, Gallery forest; Palm swamp (Vereda) and open grassland (Campo Limpo) in States of Goiás and Tocantins, Brazil (New Record). The puparium was compared with that of Brachyodina lopesi, the most closely related species with a described puparium. Despite this species clearly shared the larval pachygastrinae features it has a remarkable character not know before for this subfamily: the presence of four pairs of ventral setae (V) in the eighth abdominal segment in ventral view, while in other larvae and puparia of this subfamily, there are five pairs of ventral setae. The adult male and female were described and figured.(AU)

Schizonyxhelea thomsenae (Wirth), description of the pupa and first records from Argentina, Brazil and Peru (Diptera: Ceratopogonidae).

A New Anthropophilic Species of Simulium (Trichodagmia) (Diptera: Simuliidae) From Amazonia: Morphology, Chromosomes, and DNA Sequences.

The black fly Simulium (Trichodagmia) hirtipupa Lutz (Diptera: Simuliidae) is widely distributed in southern Brazil, with one report from Amapá state in the northern region of Brazilian Amazonia. Morphological comparison of northern and southern populations revealed differences in all life stages, corroborated by chromosomal and molecular analyses, and indicated that the population previously identified as S. hirtipupa from Amapá state represents an undescribed species. This new species is described based on all life stages above the egg, and its chromosomal and molecular divergence from S. hirtipupa is highlighted. Simulium criniferum n. sp. can be diagnosed by the deeply concave male ventral plate with a prominent median projection bearing a ventral keel; female anal lobe in lateral view with a broadly rounded, distal membranous area about as long as wide; pupa with a boot-shaped cocoon bearing a minutely bubbled surface, cephalic plate and thorax with abundant hair-like tubercles, and gill of 12 translucent filaments with darkly sclerotized, acuminate tips; and larva with the body cuticle bearing spiniform setae, abdomen truncated posteriorly, and gill histoblast in situ with the filament tips directed ventrally. Chromosomally, the new species has five unique fixed inversions and uniquely shares three additional fixed inversions with its nearest relative, S. hirtipupa. Partial COI sequences indicate a genetic distance of ~9% between the new species and S. hirtipupa. Females of the new species are anthropophilic.

Morphology and Polytene Chromosomes of a New Species of Simulium (Trichodagmia) (Diptera: Simuliidae) from the Espinhaço Mountains of Brazil.

The species richness of black flies in the Simulium (Trichodagmia) orbitale (Diptera: Simuliidae) species group is greatest in southern Brazil, where 9 of 19 species are found. A new species in the S. orbitale group was collected during a survey of black flies in Minas Gerais state, Brazil, in the Espinhaço Mountains, an area rich in endemic taxa. The new species is morphologically similar to Simulium guianense Wise (Diptera: Simuliidae), the main vector of the causal agent of onchocerciasis in Brazil and Venezuela. It can be identified in the male by the unpatterned scutum and slightly concave ventral plate with a prominent median projection, in the female by the bilobate anal lobe, in the pupa by the 12 slender gill filaments with nonsclerotized apices, branching in a rake-like pattern, and in the larva by the elongated abdominal segments V-VIII and ventrolaterally lobulate segment IX. The polytene chromosomes have one unique fixed inversion in the IS arm, relative to all other Brazilian members of the group, confirming the morphological evidence of a distinct species.

First description of larval stages of Aleochara pseudochrysorroa Caron, Mise & Klimaszewski, 2008.

Aleochara pseudochryssoroa is an abundant species near Centro Politécnico UFPR (Federal University of Paraná), Curitiba, Paraná, Brazil. This species can easily be collected in animal carcasses being an important fly regulator in this area. The adults of Aleochara prey on fly larvae, while the immature stages of Aleochara are parasitoids of fly pupae. The larvae studied here, were reared from adults of A. pseudochrysorroa collected in Curitiba, Paraná state, Brazil in animal carcasses. The immature specimens obtained were cleared and studied in glycerin in order to describe all immature stages. In this work, we describe and illustrate for the first time all larval instars of Aleochara pseudochryssoroa.

The Neotropical tanyderid Araucoderus gloriosus (Alexander) (Diptera, Tanyderidae), with description of the egg, larva and pupa, redescription of adults, and notes on natural history.

Larvae, pupae and adults of Araucoderus gloriosus (Alexander) were collected during fieldwork in Chilean Patagonia, December 2013 and January 2014. Eggs were obtained from females that oviposited in captivity. Association of all life stages is based on co-occurrence and rearing of individual larvae to adults. A diagnosis for the genus and species is provided. Descriptions of the egg, larva and pupa and redescriptions of the male and female are completed. Eggs of A. gloriosus are the first described for Tanyderidae. Natural history characteristics for this species, including microhabitat, copulatory behavior and oviposition, are discussed.

Armored Scales and Their Parasitoids on Commercial Avocados Grown in California or Imported from Mexico.

Levels of armored scales (Hemiptera: Diaspididae) on Mexican Hass avocados imported into California over May 2008-June 2009 were monitored on 135 trucks entering the state via the Blythe border station, the entry point receiving the highest volume of fruit. Levels of live sessile scales were 3.9-fold higher than indicated in a previous survey (September 2007-April 2008) although levels of live eggs and crawlers were similar to previous levels. A survey of avocado fruit in California infested with armored scales detected four species known to be endemic but failed to find any of the seven exotic Diaspididae entering the state on Mexican fruit. Monitoring of Mexican armored scales on imported avocados from September 2007 to December 2010 recovered 10 species of parasitoids predominated by two species of Signiphora Ashmead (Hymenoptera: Signiphoridae). One of these species, Signiphora flavopalliata Ashmead, comprised 36% of all collected Mexican parasitoids and is a known hyperparasitoid. A survey of armored scale parasitoids present on commercial California avocados detected 17 genetic signatures, with only four of these in common with those detected on imported Mexican fruit. The implications of these findings are discussed.

Two new species of Epimelitta Bates from Brazil and a new synonymy in Stenopseustes Bates (Coleoptera, Cerambycidae, Cerambycinae, Rhinotragini).

Two new species of Epimelitta (Cerambycidae: Cerambycinae: Rhinotragini) are described from Brazil: E. prodigiosa sp. nov., from Espírito Santo, Rio de Janeiro and São Paulo and E. penicillata sp. nov., from Santa Catarina and Rio Grande do Sul. The larva and pupa of E. prodigiosa sp. nov. are also described and illustrated. Stenopseustes gibbicollis Fisher, 1947 is synonymized with S. aeger Bates, 1873.

The family Cavognathidae (Coleoptera: Cucujoidea) in Argentina and adjacent countries.

The family Cavognathidae (Coleoptera: Cucujoidea) in Argentina is represented by three species of the genus Taphropiestes Reitter, 1875: T. fusca Reitter, 1875 [Chubut], T. magna Slipinski & Tomaszewska, 2010 [Río Negro; Chubut], and T. plaumanni Slipinski & Tomaszewska 2010 [Buenos Aires]. A total of 2565 larvae (multiple instars), 83 pupae, 2028 live adults, and 16 dead adults of T. plaumanni were found in Argentina between 2005 and 2013 in the nests of birds representing the families Columbidae, Emberizidae, Falconidae, Furnariidae, Hirundinidae, Mimidae, Passeridae, Psittacidae, Troglodytidae and Tyrannidae. The adults were most abundant in closed mud nests of Furnarius rufus (Gmelin, 1788) [Furnariidae] and its inquiline birds, but the larvae were most abundant in wood nest boxes. When T. plaumanni was scarcely represented in bird nests from some localities, Alphitobius diaperinus (Panzer, 1797), an exotic darkling beetle [Col.: Tenebrionidae: Tenebrioninae], and one native species, Phobelius crenatus Blanchard, 1842 [Col.: Tenebrionidae: Lagriinae], were most abundant in stick nests of Furnariidae. In contrast, when A. diaperinus and P. crenatus were absent in one locality from the province of Buenos Aires, T. plaumanni was the most abundant beetle. A complete account of data is provided for these collections of T. plaumanni in Argentina. Known distributional data for all Argentinian species of Taphropiestes are plotted on maps with biogeographical provinces indicated.

The immature stages of Micropygomyia (Coquillettimyia) chiapanensis (Dampf) (Diptera: Psychodidae, Phlebotominae).

The egg exochorion, larval instars and pupa of the phlebotomine sand fly Micropygomyia (Coquillettimyia) chiapanensis (Dampf) are described and illustrated based on specimens collected in the locality of Farallón, municipality of Actopan, Veracruz, Mexico. Morphology of fourth instar larval mouthparts, particularly the incisor lobe and molar lobe shape of mandible, could be important for species identification of immature Phlebotominae. In this work is compared the pupal chaetotaxy of Mi. chiapanensis with other species previously described. The fourth instar larva of Mi. chiapanensis is compared with other species of this genus, the most important differentiating characters being the size, shape and position of the abdominal dorsal internal seta.

Contribution to the knowledge of Stenochironomus Kieffer (Diptera, Chironomidae) from Brazil: seven new species and description of females and immatures of some previously known species.

Twenty two species of Stenochironomus Kieffer are known from Brazil, 19 of which occur in the Amazon region. In order to increase knowledge of the taxonomy of this genus in the Amazon region, collections were carried out in streams located in Presidente Figueiredo, Manaus and Itacoatiara municipalities, Amazonas State. Leaves and wood mined by Stenochironomus larvae were collected and transported to the laboratory where they were kept until adult emergence. Seven new species were found, one of which is described in the immature stages and as adults of both sexes (S. amazonicus sp. n.), one as immatures and adult male (S. liviae sp. n.), four as male and pupa (S. bare sp. n., S. figueiredoensis sp. n., S. gracilis sp. nov. and S. manauara sp. n.) and one only as male (S. suzanae sp. n.). Additionally, the female, pupa and larva of S. impendens Borkent, pupa and larva of S. jubatus Borkent, female and pupa of S. zonarius Borkent and female of S. palliaculeatus Borkent were described.

New morphological information on Simulium wygodzinskyorum Coscarón & Py-Daniel, 1989 (Diptera: Simuliidae).

Simulium wygodzinskyorum Coscarón & Py-Daniel was originally described based on a small number of specimens collected in Junín Province, Peru. We sampled in the same province as the type locality of this species, collecting last-instar larvae and pupae. Since the original larval description of this species was based on a single immature individual, our objective is to provide a last-instar larval description and also to provide additional morphological information on the pupa and male genitalia of this species. Some morphological characteristics not reported before for this species, such as, dorsal tubercles on larval abdominal segments, are described. Abdominal chaetotaxy of pupae is revised and the male ventral plate is fully illustrated, also it is discussed the importance of standardizing the position in which the ventral plate is illustrated. This species was collected in a stream with 2-8 m in width, exposed to sunlight with rocks of different sizes, in low density.

A new species of Metapelopia Silva, Oliveira & Trivinho-Strixino (Diptera: Chironomidae) from Peru.

A new species of the monotypic genus Metapelopia is described and illustrated based on all life stages. Adults of the Metapelopia peruensis sp. n. can be easily distinguished from those of M. corbii by the color pattern of the legs and abdomen. Larvae and pupae were collected associated with algae accumulated on rocks.
