Ocorrência e morfologia de glândulas nas pernas de Centris e Epicharis (Hymenoptera, Anthophoridae)

Occurrence and morphology of glands in legs of Centris and Epicharis (Hymenoptera, Anthophoridae)

Resumo

The presence of glands in insect legs is largely difunded. In bees they are present in solitary and social species. In Centris and Epicharis three different types of glandular structures were found: bag-shaped structures in males femur and tibia, unicelular glandular cells in ali segments of all leg pairs in males and females, but more developed in females, and differentiated epidermis in the basitarsus of both sexes. The tarsal gland present in the distal tarsomere of all legs of males and females are a special type of the bag-shaped structure. The nature of secretion and it use is unknow, but some morphological and stainning properties indicate a lipidic nature.

The presence of glands in insect legs is largely difunded. In bees they are present in solitary and social species. In Centris and Epicharis three different types of glandular structures were found: bag-shaped structures in males femur and tibia, unicelular glandular cells in ali segments of all leg pairs in males and females, but more developed in females, and differentiated epidermis in the basitarsus of both sexes. The tarsal gland present in the distal tarsomere of all legs of males and females are a special type of the bag-shaped structure. The nature of secretion and it use is unknow, but some morphological and stainning properties indicate a lipidic nature.
