A new genus and species of Angarosphecidae, Decasphex cretacicus gen. et sp. nov., is described from Burmese amber. This species is similar to Burmasphex Melo et Rosa, 2018, but can be distinguished by the unique features of 10-segmented female antenna and morphological diversity within the Apoidea.
A new genus and species of the family Angarosphecidae, Decasphex cretacicus gen. et sp. nov., from the mid-Cretaceous Burmese amber is described and illustrated. The new genus and species is most similar to Burmasphex Melo et Rosa, 2018 and can be easily distinguished in having female antenna 10 segmented (vs. 12-segmented), mesosoma more elongate, forewing with cell 2cua lower, and metasomal segments 1e3 not separated with deep constrictions. Ten-segmented female antenna is a novel morphotype example of the morphological diversity of Apoidea. A key to genera of the Angarosphecidae is provided. (C) 2020 Elsevier Ltd. All rights reserved.
