Temnothorax acutispinosus, Prebus, 2021

Prebus, Matthew M., 2021, Taxonomic revision of the Temnothorax salvini clade (Hymenoptera: Formicidae), with a key to the clades of New World Temnothorax, PeerJ (e 11514) 9, pp. 1-462 : 85

acutispinosus group overview

This group is monotypic, with the nominal Temnothorax acutispinosus sp. nov. being the only member. It is morphologically similar to the members of the acuminatus group, with which it overlaps geographically ( Fig. 93D ), but differs from them by the larger subpetiolar tooth and dorsally directed propodeal spines. However, T. acutispinosus sp. nov. is apparently more closely related to the members of the rugosus and annexus groups (Prebus, in prep.).
