ABSTRACT
ABSTRACT Zygothrica (Diptera: Drosophilidae) is an almost entirely Neotropical genus, with thirteen species found in other biogeographical regions. The genus includes around 130 valid species, of which 54 occur in Brazil. There have been no new descriptions of species of this genus since the 1987s, although a large number of undescribed species are recognized in entomological collections. Here, three species of Zygothrica Wiedemann (1830) are described from Brazil, and figures are presented for external morphology and terminalia.
ABSTRACT
ABSTRACT The use of robust sample methodologies to estimate the highest number of species with different ecological requirements and traits is essential to the knowledge construction of the biodiversity and to establish wildlife assessment and monitoring programs. Our aims were to study the performance of colored pan traps in the capture of Drosophilidae (Diptera), a method never used for sampling this taxon. During six months, colored pan traps (blue, yellow and white) were tested in three areas in Southern Brazil. We captured 375 individuals of 30 species belonging to four genera of Drosophilidae. The most abundant species were Drosophila lutzii (n=215) p=0.58, Scaptomyza sp. (n=55) p=0.15 and D. bromelioides (n=17) p=0.04, all of them, anthophilous species. All colored pan traps captured a high quantify species of Drosophilidae, mainly anthophilous species.
