A new bee species of the genus Dasypoda Latreille (Hymenoptera, Apoidea) from Portugal with comparative remarks on the subgenus Heterodasypoda Michez

Abstract

A new bee species of the genus Dasypoda Latreille (Hymenoptera, Apoidea, Melittidae), D. michezi Radchenko sp. nov., is described from south-western Portugal. This species belongs to the subgenus Heterodasypoda and appears very similar to D. albimana Pérez 1905, which occurs in the west Mediterranean Basin. A detailed comparative diagnosis of D. michezi with the other 3 species of the subgenus Heterodasypoda, is provided. The new species is most easily distinguishable by the widened protrusion at the apex of the 6th sternum, which is deeply emarginated apically in the form of a wide triangle. In addition, the new species differs from other described species of the subgenus by the structure of the 7th and 8th sterna, male genitalia, and relative dimensions of antennal flagellomeres.

Comparative ecology of two specialist bees: Dasypoda visnaga Rossi, 1790 and Dasypoda maura Pérez, 1895 (Hymenoptera, Melittidae)

“…As they are relatively rare and localised, data on their ecology are scarce. Within this bee family, the genus Dasypoda comprises 39 described species (Michez et al 2004a;Radchenko 2016Radchenko , 2017Radchenko et al 2019). Among them, nine species are recorded in Morocco (Lhomme et al 2020).…”

Assessment and conservation status of an endemic bee in a diversity hotspot (Hymenoptera, Melittidae, Dasypoda)

“…The male of Dasypoda michezi is distinguishable from its congeners by several features including the diagnostic sculpture and shape of the glossa, galea and sterna. To date however, the female of this taxon has not been described (Radchenko 2017).…”

“…Four subgenera are currently recognized within Dasypoda, with their centers of diversity found in parts of the Mediterranean region: the Balkans, Morocco and the Iberian Peninsula. Unlike the situation in many groups of wild bees, there continue to be significant additions to the knowledge of the Dasypoda fauna of Europe, with the description of new species (Radchenko 2016(Radchenko , 2017 and new records for many countries (Schmid-Egger and Dubitzky 2017; Ghisbain et al 2018;Shebl 2018;Radchenko et al 2019Radchenko et al , 2020Wendzonka et al 2020).…”

Dasypoda morawitzi Radchenko, 2016, a newly recorded solitary bee species in Hungary (Apoidea: Melittidae)

“…In this paper Dasypoda morawitzi (Radchenko, 2016) is presented as new for the Hungarian wild bee fauna. Th e species is widespread in some European countries and was recently recorded in Germany (Radchenko 2017, Scheuchl & Schwenninger 2017.…”

“…Th e genus Dasypoda Latreille, 1802 includes 40 described species worldwide that makes it the largest genus in the Melittidae family (Baker 2002, Michener 1981, Michez et al 2004, Radchenko 2016, 2017, Rasmont et al 2017. Four species have been known and listed for the Hungarian fauna so far, namely Dasypoda argentata (Panzer, 1809), D. braccata (Eversmann, 1852), D. hirtipes (Fabricius, 1793) and D. suripes (Christ, 1791) (Józan 2011).…”
