Cordiluroides Albuquerque from Costa Rica: first records, descriptions and taxonomic changes (Diptera, Muscidae, Coenosiinae)

Abstract

ABSTRACT. Cordiluroides Albuquerque from Costa Rica: first records, descriptions and taxonomic changes (Diptera, Muscidae, Coenosiinae). Cordiluroides Albuquerque is a genus of Neotropical Coenosiinae (Muscidae), known from six species. The genus is here recorded for the first time from Costa Rica, on the basis of three species: C. listrata Albuquerque, 1954, C. insularis (Willliston, 1896 and C. bistriata (Wulp, 1896) sp. rev.. We provide a key for the identification of these Costa Rican species, redescribe and illustrate their external morphological characters and terminalia. C. bistriata and C. vittifera (Stein, 1904) are both considered to be good species and are re-instated from the synonymy of C. insularis. The type material of C. listrata (Museu Nacional, Rio de Janeiro), of C. insularis and C. bistriata (The Natural History Museum, London) and of C. vittifera (Museum für Naturkunde, Humboldt-Universität zu Berlin) has been examined.

Cordiluroides Albuquerque (Diptera: Muscidae): new species and key to the Neotropical genus

“…Key to species (Modified from de Carvalho, 2002 andCouri et al, 2006) 1 Apical scutellar seta very reduced or absent (Fig. 1e and 2, 7, 8 and 9) 4 (3 7 (6) Abdomen of male very elongated, tergites 1+2 and 3 translucent yellow and with a median dorsal triangular brown cloud; tergites 4 and 5 brown, sometimes tergite 4 also translucent yellow at base; abdomen of female not elongated, brown, with lateral yellow areas on tergites 1+2 and 3 and grey pruinose on tergites 4 and 5; wings Diagnosis.…”

“…After, Couri and Gonçalves (2002) added a new species C. paulistensis to the genus. Finally, Couri et al (2006) recorded the genus for the first time from Costa Rica and revised the status of Cordiluroides bistriata and C. vittifera, removing them from the synonym of C. insularis, so that the genus has now eight valid species.…”

“…Species of the genus can be easy distinguished by the high insertion of antenna, above middle of the eye, the presence of only one pair of postsutural intra-alar setae, lower calypter transverse, and abdomen elongated (Albuquerque, 1954). There are three identification keys to the genus: Couri and Pamplona (1992) and Couri and de Carvalho (2002) for the Neotropical species, and Couri et al (2006) for the Costa Rica species. There is no information about the biology and immature stages.…”

A new genus and species of Coenosiini from Costa Rica (Diptera, Muscidae, Coenosiinae)

“…Four are currently known from Costa Rica: Bithoracochaeta Stein, 1911, Cordiluroides Albuquerque, 1954, Neodexiopsis Malloch, 1920 and Schoenomyza Haliday, 1833 (de Carvalho et al 2005; Couri et al 2006). …”
