New Cases of Gynandromorphism in Xylocopa Latreille, 1802 (Hymenoptera: Apidae)

Gynandromorphism is the most common case of sexual anomaly reported in bees and is characterized by individuals that show male and female traits simultaneously in the body. Gynandromorphic cases have been reported for 140 species of bees, an underestimated number comparing to the twenty thousand bee species described nowadays. Here we describe and illustrate the first case of a gynandromorphic Xylocopa darwini Cockerell, 1926 and the fourth case of Xylocopa varipuncta Patton, 1879. The specimens show a mixed form of gynandromorphism with predominantly female features and with all its male traits concentrated in one side of the body, right side in X. darwini and left side in X. varipuncta. The gynanders of X. darwini and X. varipuncta were collected on Isabela Island (Galapagos – Ecuador) and Riverside (California – USA), and were deposited in Smithsonian Collection and California Academy of Sciences, respectively. Including this work, eighteen cases of gynandromorphism were reported to Xylocopa and twelve were recorded from Neoxylocopa subgenus

Belo Horizonte, MG, BrasilBackground: Sand fly collections were performed to study ecological aspects of the Phlebotominae fauna of the Xakriabá Indigenous Reserve, an area with endemic cutaneous leishmaniasis, located in the state of Minas Gerais, Brazil. Methods: The collections were performed in peridomicile areas and along trails previously selected for the study of wild and synanthropic Leishmania hosts. Differences in the distribution patterns of the sand fly species as well as in species richness and abundance between the different ecotopes were investigated during both rainy and dry seasons over the course of the study period. Results: A total of 8,046 sand flies belonging to 11 genera and 28 species were collected. Lutzomyia longipalpis and Nyssomyia intermédia were the most abundant species in peridomicile areas, whereas Martinsmyia minasensis and Lutzomyia cavernícola were the most abundant species among the different trail ecotopes. Conclusion: The different composition of the sand fly fauna observed in the peridomicile areas and in the trails during the study, reinforces the importance of sampled different areas in a phlebotomine fauna survey. The presence of Lutzomyia longipalpis and Ny. Intermedia most abundant in peridomicile can be important to Leishmania infantum and Leishmania braziliensis transmission in the Imbaúbas native village
