Two new Neotropical species of the genus Oxysarcodexia Townsend (Diptera, Sarcophagidae)

Abstract

ABSTRACT. Two new Neotropical species of the genus Oxysarcodexia Townsend (Diptera, Sarcophagidae). Oxysarcodexia nitida sp. nov. and O. notata sp. nov. from Peru are described and illustrated based on male specimens. These new taxa are morphologically more similar to O. vittata (Walker) and O. xon (Dodge) respectively.

A new flesh fly species of Oxysarcodexia Townsend from the Brazilian Atlantic Forest and redescription of Oxysarcodexia xon (Dodge, 1968)

“…Early authors considered Oxysarcodexia species with apical phallic enlargement under the distinct genus Xarcophaga (Dodge, 1968, but current authors have dealt with these species under Oxysarcodexia, following the synonymic proposal of Lopes (1975a) and , although species with phallic enlargement have been referred as "Xarcophaga group" or "xon species-group" (Soares & Mello-Patiu, 2010;Souza & Paseto, 2015;Souza & Buenaventura, 2016;Dufek & Mulieri, 2017). However, until now there is no formal proposition between species-groups or subgenera in Oxysarcodexia.…”

“…synonymized all these four genera under Oxysarcodexia. Subsequent authors have agreed with this genus concept and other species of Oxysarcodexia referred under "xon species-group" or "Xarcophaga group" have been described (Soares & Mello-Patiu, 2010;Souza & Paseto, 2015;Souza & Buenaventura, 2016;Dufek & Mulieri, 2017). Currently, there are 13 species of Oxysarcodexia recognized by several authors as related to "xon species-group": O. berthet Dufek & Mulieri, 2017;O.…”

“…Oxysarcodexia Townsend, 1917 has 90 known species and it is one of the largest genera of Sarcophagidae, with 83 species recorded in the Neotropical region (Lopes & Tibana, 1987;Soares & Mello-Patiu, 2010;Souza & Paseto, 2015;Souza & Buenaventura, 2016;Carvalho-Filho et al, 2017;Dufek & Mulieri, 2017). The genus diversity associated with the great similarity among the species lead to a difficulty in the identification at species level (Pape & Dahlem, 2010;Soares & Mello-Patiu, 2010).…”

The genus diversity associated with the great similarity among the species lead to a difficulty in the identification at species level (Pape & Dahlem, 2010;Soares & Mello-Patiu, 2010). Adults of Oxysarcodexia are one of the most frequent and abundant flesh flies reported in field collections, including studies on decomposition process using carrion-baited traps or pigs, and also in human corpses (Carvalho et al, 2000;Martínez et al, 2007;Barros et al, 2008;Barbosa et al, 2009;Battán Horenstein et al, 2010;Oliveira-Costa et al, 2001Oliveira & Vasconcelos, 2010;Lindgren et al, 2015;de Faria et al, 2017).…”

Description of a Neotropical New Species of OxysarcodexiaTownsend, 1917 (Diptera: Sarcophagidae)

“…xysarcodexia Townsend, 1917 (Diptera: Sarcophagidae) comprises 83 species (PaPe 1996;SoareS & Mello-Patiu 2010) with mainly Neotropical distribution, but few species also expanding their occurrence to the Nearctic, Australasian and Oceanian regions (loPeS 1973;loPeS & tibana 1987;PaPe 1996). This genus is considered monophyletic based on the autapomorphic character: presence of a lateral triangular extension of the phallic tube ("tooth-like") above the vesica (Giroux et al 2010).…”
