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.
