“…An interesting result of this study concerns the high level of cryptic diversity. In addition to the 22 species that have been previously described, we sampled at least 24 putative new species, which should be further described and added to the list of 75 Brazilian species included in the Zygothrica genus group (Vilela & B€ achli, 2007;Gottschalk et al, 2008;Robe et al, 2014). Nevertheless, cryptic or unregistered diversity levels are probably still underestimated.…”

Within Drosophilidae, the Zygothrica genus group corresponds to a speciose mycophagous group, which remains insufficiently investigated despite its potential for ecological and evolutionary studies. The recognised gap in the knowledge of species diversity and the threat provided by global warming due to niche conservatism and stringent temperature and humidity requirements make this group an excellent candidate for testing the implementation of DNA barcoding, which is the aim of this study. Extensive prospecting in various parts of Brazil provided 220 specimens. Considering both the morphological and molecular results, these individuals consisted of 56 species that could be distributed into three categories: 22 corresponded to previously described species, 24 very likely corresponded to undescribed species, and 10 uncertain cases corresponded mainly to one or a few females. Intra‐specific distances ranged from 0% to 5.3%, whereas inter‐specific congeneric and inter‐generic distances ranged from 2.4% to 21.7% and from 7.4% to 20% respectively. Moreover, all species were revealed as reciprocally monophyletic and presented positive barcoding gap values; 62.5% of them presented diagnostic characters. Although coalescent‐based methodologies suggested some additional splitting, species initially considered to be different were never lumped together. Therefore, in general, DNA barcoding of mycophagous drosophilids provided results that are largely congruent throughout different molecular approaches and also with morphological boundaries. Several putative new species were revealed, highlighting the potential of cytochrome c oxidase subunit I (COI) barcodes as a tool complementary to traditional taxonomy in unravelling cryptic diversity among Neotropical mycophagous drosophilids.

Comparison of Drosophilidae (Diptera) assemblages from two highland Araucaria Forest fragments, with and without environmental conservation policies

et al. 2014

Flies from the Drosophilidae family are model organisms for biological studies and are often suggested as bioindicators of environmental quality. The Araucaria Forest, one of Atlantic Forest phyto-physiognomy, displays a highly fragmented distribution due to the expansion of agriculture and urbanization. Thus, this work aimed to evaluate and compare the drosophilid assemblages from two highland Araucaria Forest fragments, one a conservation unit (PMA -Parque Municipal das Araucárias) and the other a private property without any conservational policy (FBL -Fazenda Brandalise), in space and time, using species abundances and richness, ecological indexes and Neotropical and exotic species proportions as parameters to establish the level of environmental quality of these fragments. Our results showed that the observed diversity in PMA (H' = 2.221) was approximately 40% higher than in FBL (H' = 1.592). This could be due to higher preservation quality and habitat diversity in PMA, indicating the importance of conservation units. However, richness were similar for these areas, with PMA (D mg = 6.602) only 8% higher than FBL (D mg = 6.128), which suggest that the larger distance from city limits and the larger size of FBL forested area could be compensating the higher disturbance caused by antrophic extractive exploitation of this fragment. This points out that, besides the quality of presevertion, the size and/or connection with other fragments should be considered for areas destined for biodiversity conservation. In general, both areas presented similar drosophilid assemblages, and the expressive abundance of both Neotropical species (mostly of the subgroup willistoni) and the exotic species D. kikkawai suggests that these areas are in intermediate stages of conservation.Keywords: ecological indexes, Mixed Ombrophylous Forest, exotic species, Drosophila, Atlantic Forest, Neotropical region.

En estudios realizados en el bosque nublado Intillacta, provincia de Pichincha, Ecuador, y en la Cordillera de los Guacamayos, provincia de Napo, Ecuador, se encontró una nueva especie de Drosophila. En base a estudios de la morfología de la genitalia masculina, se propone que, Drosophila intillacta sp. nov. pertenece al grupo Drosophila annulimana. Así mismo, se reporta Drosophila tarsata Schiner, 1868, capturada en la Cordillera de los Guacamayos, como un nuevo registro para el país.
