Leioproctus (Otagocolletes), Engel & Kaulfuss, 2025

Otagocolletes n. subgen.

TYPE SPECIES. — Leioproctus (Otagocolletes) barrydonovani n. sp.

DIAGNOSIS. — The new subgenus is similar to Nesocolletes Michener, 1965 in the possession of a more pronounced malar space (i.e., at least longer than 0.5× the basal mandibular width), about as long as wide in the fossil, and the short and wholly declivitous basal area to the propodeum but differs in the more parallel-sided pterostigma, the distal origin of r-rs, the more abruptly tapered pterostigmal border within the marginal cell (more convex in Nesocolletes), the weakly and evenly arched 2rs-m, and shortened second medial cell (vide etiam Discussion, infra).

ETYMOLOGY. — The new subgeneric name is a combination of the Otago region, southern Māori dialect version of Ōtākou, and kollitís (ΚΟλλητής, meaning, “gluer” or “one who glues”). The gender of the name is masculine.
