Key for Oxystoglossella species from South America

Lepeco and Goncalves (2022) proposed two informal species groups for the subgenus based on their phylogenetic results: the A. iphigenia group (for species with slightly produced or transverse basal elevation of labrum) and the A. morrae group (for species with orbicular basal elevation of labrum). Herein, a refined scheme of informal species subgroups based on morphological features is proposed to facilitate species identification, as we proceed in determining species. Within the A. iphigenia group, a subgroup can be readily identified by female S1 tuberculate and male sternal modifications, the A. modica subgroup ( A. mendax , A. modica , A. simplex sp. nov. and A. tenax ). The species of the A. iphigenia subgroup have broad subapical tooth and strong cephalic polymorphism ( A. iphigenia , A. matucanensis and A. phoenicis ). Within the A. morrae group, two subgroups can be separated by the ornamentation of mesepisternum, rugulose anteriorly to mesepisternal groove on A. morrae subgroup ( A. antonita , A. cymatoides , A. erubescens , A. laevinota sp. nov., A. morrae , A. obidensis sp. nov. and A. thalia ) and punctate anteriorly to mesepisternal groove on A. aurinasis subgroup ( A. almeidai sp. nov., A. aurinasis , A. brevipilosa sp. nov., A. eucnemis , A. lamellata sp. nov. and A. mineira sp. nov.). Augochlora rightmyerae and A. meloi sp. nov. are distinct from other species, but they can be associated with the A. morrae and A. aurinasis subgroups, respectively, based on mesepisternum ornamentation.
