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.
