Description

Genus Nesostenodentus Cushman, 1922

Nesostenodontus Cushman, 1922: 554. Type species: Nesostenodontus bakeri Cushman, 1922, by original designation and monotypy.

Remarks

Cushman (1922: 554) described the genus Nesostenodontus to accommodate only one species, N. bakeri Cushman, 1922, based on the following combination of characters: (1) unidentate mandible; (2) swollen genae and head almost cubic; (3) strongly dentate clypeus; (4) propodeum almost devoid of carinae, without long spines; (5) scutellum not bordered by carina; gastrocoeli and thyridia indistinct. Later on, Heinrich (1934: 129) added a new species to the count, N. celebensis Heinrich, 1934, whereas Cushman (1937: 284), while describing N. formosanus Cushman, 1937, identified some variation within the genus: the very elongated malar space, the convex clypeus, and the distinct anterior and posterior propodeal carinae. A close examination of the holotype of Heterishcnus mkomazi Rousse & van Noort, 2013 revealed that the species shares many features with the genus Nesostenodontus. Therefore, we transfer mkomazi to the genus Nesostenodontus. Below, we provide reasons for this new combination together with a new diagnosis of the species.

Before this contribution, the genus was recorded only from the Indomalayan region. This new combination marks the first record for the Afrotropical region.
