description: Key to males and females* of species of Argoravinia
* The females of A. candida, A. catiae, and A. timbarensis are unknown.
1. Five to six fronto-orbital bristles. Four post-sutural dorsocentral bristles, first two weak. Male cercus with prong strongly bent backwards and with a cluster of spines on dorsal surface (Figs. 17, 18, 24, 26, 35). Gena usually grayish with black setae …subgenus Argoravinia ................................................................................ 2
- Seven to 12 fronto-orbital bristles. Three post-sutural dorsocentral bristles. Male cercus with prong almost straight and without spines on dorsal surface (Figs. 5, 41), or if bent backwards then without spines on dorsal surface. Gena usually golden with whitish setae … subgenus Raviniopsis ..................................................................... 8
2. Males.............................................................................................. 3
- Females............................................................................................. 6
3. Lateral epandrial apophysis narrow and very long, as long as bent portion of cercus (Figs. 1, 16). Lateral apophysis with tip
claw-like, pointed and gently curved downwards (Figs. 1, 16). [Brazil, Colombia, Trinidad & Tobago, Venezuela]................................................................................... A. (Argoravinia) alvarengai Lopes - Lateral epandrial apophysis wide and short, shorter than bent portion of cercus (Figs. 2, 3, 4, 21, 25, 33, 34). Lateral apophysis with apex rounded and not pointed (Figs. 2, 3, 4, 21, 25, 33, 34)................................................. 4
4. Lateral apophysis very large, fully hiding the surstylus and projecting above dorsal surface of cercus (Figs. 2, 21) [Brazil].............................................................................. A. (Argoravinia) catiae sp. nov.
- Lateral apophysis narrow, hiding only basal portion of surstylus and most of the lateral portion of cercus (Figs. 3, 4, 25, 33, 34).................................................................................................... 5
5. Three pre-sutural dorsocentral bristles. Pregonite apex with two rounded tips (Figs. 8, 29). Lateral apophysis cone-shaped, with large base and narrow apex, not reaching beyond lateral margin of cercus (Figs. 3, 25) [United States to Argentina, Marshall Islands]........................................................ A. (Argoravinia) rufiventris (Wiedemann)
- Two pre-sutural dorsocentral bristles. Pregonite apex with two claw-like tips (Figs. 9, 36, 37). Lateral apophysis tongueshaped, with base little narrowed in relation to apex, reaching beyond lateral margin of cercus (Figs. 4, 33, 34) [Brazil].............................................................................. A. (Argoravinia) paraensis sp. nov.
6. Three pre-sutural dorsocentral bristles..................................................................... 7
- Two pre-sutural dorsocentral bristles [Brazil].................................... A. (Argoravinia) paraensis sp. nov.

10. Post-sutural acrostichal bristles absent. Meron with 7–8 bristles. Three pairs of marginal scutellar bristles [Cuba, Jamaica, Puerto Rico]................................................................ A. (Raviniopsis) candida (Curran)
- One weak post-sutural acrostichal bristle. Meron with 9–11 bristles. Two pairs of marginal scutellar bristles............ 11
11. Distiphallus in lateral view with glans (dark region inside distiphallus) narrow, restricted to lateral margin of distiphallus (Fig. 45) [Mexico to Brazil, Marshall Islands]....................................... A. (Raviniopsis) aurea (Townsend)
- Distiphallus in lateral view with glans large, from median region to lateral margin of distiphallus (Fig. 43) [southern Brazil]........................................................................... A. (Raviniopsis) brasiliana (Lopes)
