Abachrysa (Brooks & Barnard 1990: 165, Figs 125–132;

Breitkreuz 2018: 254–258; here, Figs 12–22).

A monotypic genus. Size: Body stout, relatively large; wing length 12.6–18.5 mm; males and females of similar size. Coloration: Cream to gold with bold black markings on thorax, abdomen, and legs; antennal flagellum dark basally. Wings: Slender, tips rounded; ratio of forewing length to width = ~3.2: 1; forewing and hindwing without splayed crossveins or dark markings, with most veins dark, interrupted by pale areas basally and within some longitudinal veins and crossveins. Tarsal claws: Basal dilation present. Abdomen: Setae numerous short, stout. Male: Ectoproct extending proximally as far as mid A8; dorsal apodeme of T9+e with a right-angled bend mesally, with basal section extending downward through at least half the length of A8; S8+9 fused with prominent suture visible; S6–S8 with microtholi; gonarcus without gonocornu, with frontal plate; parameres large, with membranous fusion basally. Female: Abdominal tergites with distinct mesal suture; dorsum of T9+e with deep mesal invagination; praegenitale present, visible externally.

In summary, Abachrysa is the only New World belonopterygine genus having a robust, pale body with bold markings, no wing markings or splayed costal veins, with males having large paired parameres joined in a V-shape, and females having the abdominal tergites mesally divided or very lightly fused and a praegenitale present externally.
