Registro de hospedeiro de Austrostelis Michener & Griswold (Hymenoptera: Megachilidae) e de sua ocorrência na caatinga

Abstract

-It is recorded the emergence of specimens of the cleptoparasitic bee Austrostelis catamarcencis (Schrottky) from nests of Epanthidium tigrinum (Schrottky) in the central area of the Caatinga, the semi-arid region from Northeastern Brazil.

Origins, Evolution, and Diversification of Cleptoparasitic Lineages in Long-Tongued Bees

“…In 1871, Hermann Müller observed that the hosts of cleptoparasitic bees are often other species of bees to which they are closely related (Müller ); nearly four decades later, Carlo Emery made a similar observation regarding the appearance of social parasitism in ants (Emery ). This trend, originally called “Müller's Law” (Popov ), also often referred to as “Emery's Rule,” is particularly apparent in young cleptoparasitic clades: the erythrogastra species group of Hoplitis ( Hoplitis ) on closely related species belonging to the same subgenus (Megachilidae, Osmiini; Sedivy et al ); Coelioxys and Radoszkowskiana on Megachile (Megachilidae, Megachilini; Rozen et al and references therein); Exaerete and Aglae on Eufriesea and Eulaema (Apidae, Euglossini; Bennett ; Garófalo and Rozen ); Austrostelis on Epanthidium (Megachilidae, Anthidiini; Zanella and Ferreira ); Dialictus on other species of Dialictus (Halictidae, Halictini; Michener ), and likely Ctenoplectrina on Ctenoplectra (Apidae, Ctenoplectrini; Schaefer and Renner ).…”

Espécies novas de Epanthidium Moure e de Austrostelis Michener & Griswold (Hymenoptera, Apidae, Megachilinae)

“…O Prof. Fernando C. V. Zanella (comunicação pessoal e fotos de espécimes) coletou exemplares de A. maranhensis na Paraíba, no Pico do Jabre, município de Maturéia, próximo de Patos. Zanella & Ferreira (2005) …”

Nests of bees of the anthidiine genus Ananthidium Urban (Hymenoptera, Apidae, Megachilinae)

“…The tribe also possesses obligatory cleptoparasitic genera that parasitize other species of Megachilinae, with a few taxa attacking unrelated bee groups, such as Hoplostelis Dominique that parasitizes nests of orchid bees (Apinae, Euglossini). Reports on the nest biology of the tribe are relatively scarce, especially for neotropical taxa (Jörgensen 1912, Claude-Joseph 1926, Janvier 1955, Laroca and Rosado-Neto 1975, Morato and Campos 2000, Morato 2001, Alves-dos-Santos 2004, Camarotti-de-Lima and Martins 2005, Zanella and Ferreira 2005, Rozen 2015, Alvarez et al 2015. Among Brazilian species, limited information indicates that Dicranthidium arenarium (Ducke, 1907) (Laroca and Rosado-Neto 1975) and Anthodioctes manauara Urban, 1999(Morato 2001 construct their nests in abandoned mud nest of eumenine wasps.…”
