On the identity of Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) (Diptera: Sarcophagidae) and a new generic synonym
The revision of the sarcophagid species Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) reveals its identity and a generic synonym. The male terminalia of this species was studied in detail for the first time and revealed its congeneric affinities with Oxyvinia Dodge, 1966. Consequently, the generic status of Orosarcophaga Townsend, 1927 was revalidated, including Oxyvinia Dodge, 1966 as its junior synonym, and O. ornata was corroborated as a valid species and name. Moreover, we provide an updated generic diagnosis of Orosarcophaga, a list of the eleven species of the genus with their distribution, and a detailed diagnosis of O. ornata
Morfologia Comparada da Terminália Masculina de Quatro Espécies de Oxysarcodexia Townsend, 1917 (Diptera, Sarcophagidae)
Many species of Oxysarcodexia, one of the most numerous neotropical genera of the family Sarcophagidae, are known only by descriptions which do not supply enough arguments for species segregation, mainly by the lack of detailed morphological study of the genitalia. A comparative and elaborate study of the male terminalia of O. avuncula, O. confusa, O. diana and O. parva, species with very similar morphology, has resulted in the survey of a character set which has allowed the species segregation.Muitas espécies de Oxysarcodexia, um dos gêneros neotropicais mais numerosos da família Sarcophagidae, são conhecidas apenas por descrições que não fornecem argumentos suficientes para sua segregação, principalmente pela falta de detalhamento da morfologia da genitália. Um estudo comparativo e minucioso da terminália masculina de O. avuncula, O. confusa, O. diana e O. parva, espécies morfologicamente bastante similares, resultou no levantamento de um conjunto de caracteres que permitem uma melhor segregação das espécies
Contribution to the knowledge of flesh flies (Diptera: Sarcophagidae: Sarcophaginae) attracted to carcasses in Piura, Peru
Despite being the most diverse family of flies found in carcasses and corps in the Neotropical Region, Sarcophagidae is still underestimated in Peru. This research was developed in the Department of Piura, Northern Peru and we identify the flesh flies captured on two kinds of animal carcasses: dog and guinea pigs. As a result, a new record was documented for Peru: Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830) and eight new records for the Department of Piura
Redescrição de Stylogaster Stylata (Fabricius, 1805) (Diptera, Conopidae), com Ênfase na Morfologia da Terminália e do Ovo
Stylogaster stylata (Fabricius, 1805) is redescribed and illustrated based on material from Brazil, including a detailed morphological study of male and female, with emphasis on the terminalia, and egg.Stylogaster stylata (Fabricius, 1805) é redescrita e ilustrada com base em material procedente do Brasil, incluindo um estudo morfológico detalhado de macho e fêmea, com ênfase na terminália, e do ovo
Checklist of the dipterofauna (Insecta) from Roraima, Brazil, with special reference to the Brazilian Ecological Station of Maracá
Roraima is a Brazilian state located in the northern portion of the Amazon basin, with few studies regarding its biodiversity. The Ecological Station of Maracá (Brazil, state of Roraima) harbors the third largest Brazilian pluvial island and is composed of a transitional landscape of savanna and Amazon rainforest components. Despite its ecological importance and strategic localization, few studies covered the dipterofauna of this locality. An updated checklist addressing 41 families of true flies (Diptera) occurring in Roraima is presented based on the literature and the specimens collected during a field expedition that occurred in 2015. This checklist brings several improvements such as new records of 165 taxa to the state of Roraima, 29 taxa to Brazil, and 259 morphotypes, mostly likely representing undescribed species
