Spanionomia (Spanionomia) Engel & Tran 2025, n. subgen.

Spanionomia Engel & Tran, n. subgen. TYPE SPECIES. — Nomia elegans Smith, 1857. ETYMOLOGY. — The new subgeneric name is a combination of the Ancient Greek adjective σπᾰ́νῐΟς (spánios), meaning, “sparse” or “rare”, and the generic name Nomia Latreille. The gender of the name is feminine. DIAGNOSIS. — This subgenus is quite distinctive from all other Maculonomia for the comparatively sparse setation of the metatibial scopa and the light coloration of the legs, which are also rather thin in the male, and with scarcely any apical lobe present on the metatibia (versus the well-developed lobes of Maculonomia s.str.). Aside from the type species the subgenus also includes Maculonomia concinna Smith, 1860.
