Phylogeny and revision of Messatoporus Cushman (Hymenoptera, Ichneumonidae, Cryptinae), with descriptions of sixty five new species.

The large New World genus Messatoporus Cushman is diagnosed, redefined, described, and its species revised. A total of 89 valid species are recognized, of which 65 are described as new. All previously known species are redescribed and illustrated. The following synonyms are proposed: M. jocosus (Provancher) and M. rufiventris Cushman under M. discoidalis (Cresson), syn. nov. and M. tricolor (Szépligeti) under M. variegatus (Szépligeti) syn. nov. The following new species are proposed: M. advenus, M. albiaterartus, M. allomeros, M. amarelus, M. amazonensis, M. amplithorax, M. andinus, M. anepomius, M. apiopharkis, M. argentinus, M. atlanticus, M. atrifoveus, M. aurantius, M. badius, M. basiflavus, M. bennetii, M. bicolor, M. bimaculatus, M. campanulatus, M. caxiuanensis, M. citreocephalus, M. complexifemur, M. concavivenus, M. convexus, M. copiosus, M. depressifrons, M. dialeipsis, M. dissidens, M. dominicanus, M. elektor, M. ellipsicavus, M. euryoikos, M. igneus, M. interceptus, M. keraiopetalus, M. laevilatus, M. latissulcus, M. longicaudis, M. longitergus, M. lordos, M. lunatus, M. maculiscus, M. matucanus, M. nigriangulatus, M. nigriscapus, M. nigriscutus, M. occidentalis, M. opacus, M. orientalis, M. paeneater, M. pallidus, M. paradoxus, M. paralissonotus, M. pleuriflavus, M. semialbiventris, M. semiaurantigaster, M. subalaris, M. tenuiorbis, M. tenuissimus, M. teutonicus, M. titans, M. unidentatus, M. unimaculatus, M. versicolor and M. xanthogaster spp. nov. As well, a lectotype is designated for M. townesi Alayo and Tzankov, and Messatoporus nigrispina (Cameron) is transferred to Prosthoporus Porter, comb. nov.. A key to species based on both sexes is also presented, and new distribution records and distribution maps are provided. The validity and relationships of the genus are investigated cladistically using 162 morphological characters for 27 species of Messatoporus and 105 outgroup taxa. Tree search was conducted using TNT under implied weighting, with values of 1­6 for the concavity constant (K). All analyses recovered Messatoporus as a monophyletic group, supported by 7­11 synapomorphies. The results also support the monophyly of the six studied genera of Osprynchotina, in a clade including also Dotocryptus Brèthes. Messatoporus is diagnosed by the combination of the following features: apicolateral corners of clypeus projected; mandible long and tapered, ventral tooth much shorter than dorsal one or indistinct; transverse sulcus at base of propodeum long and shallow; anterior margin of propodeum concave; posterior area of propodeum almost always transversely wrinkled; first metasomal spiracle placed approximately on midlength; median dorsal carina of first metasomal segment absent; ovipositor basally cylindrical, apically depressed, with ventral valve enclosing completely dorsal valve as a sheath. A second analysis including all species of the genus was performed to evaluate the phylogeny at the genus level. The character set for that analysis included 104 characters considered of phylogenetic importance within the genus, and used the same tree searching protocol as the first one. A distinct and gradual transition is detected, from species more similar to the remaining Osprynchotina to a significantly different morphotype with several convergences with the Gabuniina. These convergences are interpreted as adaptations to host location and substrate perforation, and may be related to use of more deeply concealed hosts.

Revision of Fortipalpa Kasparyan & Ruíz-Cancino, (Ichneumonidae, Cryptinae).

Fortipalpa Kasparyan & Ruíz-Cancino, 2007 originally accommodates only its type species, F. yucatanica Kasparyan & Ruíz-Cancino, 2007. The genus can be distinguished from all other Neotropical Cryptini by having mandible with ventral tooth subequal to slightly longer than dorsal tooth; propodeum anteriorly smooth, posteriorly with transverse striation; T1 long and slender, without anterolateral tooth; and ovipositor moderately long and straight, with ventral valve without a lobe covering dorsal valve. The genus is revised, and the following new species are proposed, described, and illustrated: F. exelysae sp. nov., F. frida sp. nov., F. heredia sp. nov., F. panamensis sp. nov., F. pichincha sp. nov., F. sacha sp. nov., and F. shakira sp. nov. The male of F. exelysae sp. nov., the first for the genus, is also described and illustrated; other males remain unknown. The type species is redescribed and illustrated, including pictures of the paratype and a new record to Trinidad. Figures, distribution maps and a taxonomic key are provided for all valid species.

Clinical case report: treatment of permanent tooth avulsion following trauma from a dog bite.

This article reviews the treatment of a pediatric patient following head and neck trauma from a dog bite. The patient had an avulsed mandibular incisor, a fractured maxillary lateral incisor, and various facial lacerations. The avulsed tooth was replanted and secured for two weeks by using a physiologic splint. Both traumatized teeth received endodontic therapy and were returned to normal function. Trauma patients require a thorough evaluation and a multidisciplinary approach for the formation of a proper treatment plan.

A new species and southernmost record of Cestrus Townes (Hymenoptera, Ichneumonidae, Cryptinae).

Cestrus itatiensis sp. nov., from the Brazilian Atlantic Forest, is described and illustrated. This is the southernmost record for the genus and the first record in Brazil. The new species is characterized by having the body reddish brown; a narrow yellow stripe along eye margin on supra-clypeal area, reaching briefly the supra-antennal area; transverse carina of propodeum complete and stout; postpetiole and T2-8 progressively dark brown towards apical margin in a somewhat triangular pattern; and apex of dorsal valve of ovipositor with nine distinct teeth. Extensive sampling suggest this is a rare species.

Species delimitation, environmental cline and phylogeny for a new Neotropical genus of Cryptinae (Ichneumonidae).

A morphologically unusual Cryptini, Cryptoxenodon gen. nov. Supeleto, Santos & Aguiar, is described and illustrated, with a single species, C. metamorphus sp. nov. Supeleto, Santos & Aguiar, apparently occurring in two disjunct populations in northern and southeastern South America. The highly dimorphic female and male are described and illustrated. The phylogenetic relationships of the new genus are investigated using a matrix with 308 other species of Cryptini in 182 genera, based on 109 morphological characters and molecular data from seven loci. The analyses clearly support Cryptoxenodon gen. nov. as a distinct genus, closest to Debilos Townes and Diapetimorpha Viereck. Species limits and definition are investigated, but despite much morphological variation the analyses at the specimen level do not warrant the division of the studied populations into separate species. The considerable morphological variation is explored with principal component analyses of mixed features, and a new procedure is proposed for objective analysis of colors. The relationship of color and structural variation with altitude and latitude is demonstrated and discussed, representing an important case study for Ichneumonidae. Externally, Cryptoxenodon gen. nov. can be recognized mainly by its unusually large mandibles, but other diagnostic features include clypeus wide; sternaulus complete, distinct and crenulate throughout; areolet closed, about as long as pterostigma width; petiole anteriorly with distinct triangular projection on each side, spiracle near posterior 0.25; propodeum without posterior transverse carina; and propodeal apophyses conspicuously projected.

Rapid detection of Salmonella sp. in pork samples using fluorescent in situ hybridization: a comparison with VIDAS®-SLM system and ISO 6579 cultural method / Detecção rápida de Salmonella sp. em amostras de suinos por hibridação in situ fluorescente: comparação com o sistema VIDAS®-SLM e com o método de cultura ISO 6579

This study reports the use of the fluorescent in situ hybridization (FISH) with Sal3 probe for Salmonella detection in swine carcasses inner surface (swab); and in the correspondent samples of ileum, ileocolic, and mandibular lymph nodes; and tonsils, after dilution (1:10) in buffered peptone water and a pre-enrichment step (37(0)C, 18h). In order to evaluate the efficiency of FISH, 235 naturally contaminated samples were simultaneously tested by the cultural method (ISO 6579) and by the Vitek Immuno Diagnostic Assay System (VIDAS®) - Salmonella (SLM) system. The cultural method identified 39 positive samples. From these, VIDAS®- SLM only detected 23. FISH identified 115 positive samples. This difference was highly significant (P<0.001). From positive samples, 32 were also confirmed by the cultural method. The results indicate FISH as a promising tool for rapid Salmonella detection in samples of pork and swine carcasses

Descreve-se a utilização da técnica de hibridação in situ fluorescente (FISH), utilizando a sonda Sal3, para detecção de Salmonella na superfície interna de carcaças de suínos (zaragatoa), em amostras correspondentes de íleo, linfonodos ileocólicos, linfonodos mandibulares e amígdalas, após terem sido diluídas (1:10) e submetidas a uma fase de pré-enriquecimento em água peptonada tamponada (a 37ºC, 18h). Para avaliar a eficácia do método FISH, analisaram-se 235 amostras naturalmente contaminadas, usando o método de cultura ISO 6579 e o sistema Vitek Immuno Diagnostic Assay System (VIDAS®)- Salmonella (SLM), simultaneamente. O método de cultura identificou 39 amostras positivas, das quais o método VIDAS®-SLM detectou apenas 23. O método FISH identificou 115 amostras positivas. A diferença entre os métodos foi altamente significativa (P<0.001). Das amostras positivas, 32 foram confirmadas pelo método de cultura. Os resultados indicam que a FISH constitui uma promissora técnica de detecção rápida de Salmonella em amostras de suínos abatidos para consumo
