          Abstract

          ABSTRACT A taxonomic revision of Megalothoracha Hendel, 1911 is provided, including a description of Megalothoraca rosalyae Wendt, sp. nov. from Colombia. The genus encompasses large species from Colombia, Ecuador, Peru and Bolivia (new record), and each species was described based either on males or females. These species can be diagnosed by long and slender mid and hind legs and wing longer than body, vein R2+3 with two strong curves on apical third, and short spurious vein medially. And males have costal vein conspicuously bowed anteriorly and thickened on medial portion. The following nomenclatural changes are made: Megalothoraca hendeli Enderlein, 1912, syn. nov. is a junior synonym of M. pterodontida Hendel, 1911; Batrachophthalmum teleopsis (Hennig, 1938) comb. nov. is transferred from Megalothoraca, and Batrachophthalmum quimbaya Carvalho, Wolff & Wendt, 2011, syn. nov. is a junior synonym of B. teleopsis. A key to species and illustrations of the female and male terminalia are provided.

            Seasonality of insect succession and pig carcass decomposition in a natural forest area in southeastern Brazil.

            In this study, successional patterns, relative abundance of larvae and adults of sarcosaprophagous insects, carcass decay, diversity and seasonality of species, and their potential as forensic indicators were studied. Four experiments were carried out in each season in a natural area of southeastern Brazil. Two pigs (Sus scrofa L.) were used in each experiment and were exposed to sunlight and shade, respectively. The Calliphoridae outnumbered the Sarcophagidae in specimens collected and reared from the carcasses. More insects were collected from carcasses exposed to the sun, while a larger number of specimens were reared from those in the shade. Temperature and rainfall influenced the stages of carcass decay and insect activity and abundance. Chrysomya albiceps was the most abundant species in all four experiments. The carcasses were used as a protein source and substratum for oviposition. The dark putrefaction and fermentation stages yielded more flies than the other stages. These results show that flies are important in carcass decay and are, therefore, also of forensic importance. Seven species can be considered valuable forensic indicators in Southeastern Brazil. However, only three species were useful as forensic indicators in wooded areas: P. intermutans, H. segmentaria, and H. semidiaphana.
