Temnothorax altinodus, 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 : 89

altinodus group overview

This group is monotypic, with the nominal Temnothorax altinodus sp. nov. being the only member. It is morphologically similar to the members of the acuminatus and acutispinosus groups, sharing a lack of setae on the propodeal dorsum. It can be distinguished from these groups by the larger subpetiolar tooth (small in the acuminatus group) and the incrassate femora (not incrassate in the acuminatus and acutispinosus groups). Known from a single collection in the mid elevations of Honduras ( Fig. 94D ), this species is apparently sister to the fuscatus and pergandei groups (Prebus, in prep.).
