Scapteriscus Scudder, 1868

(figs. 1–10, 20 – 37)

Epiphallus: Transversal sclerite “ Y ”- shaped, ventro apical branch more developed than the dorsal one, tubular bmp, protuberant amp and three or four times longer than it is wide.

Ectophallus: Wide, with an expanded basal plate, wavy lateral margins, antero-apical process present, pedunculate and sclerotized, apical process thorn-shaped and almost as long as the antero-apical processes.

Comments. S. oxydactylus has genital variation regarding the species studied here: the apical sclerite of the epiphallus is reduced, only 1.5 times longer than it is wide, antero-apical process mostly membrane-like and shorter than the apical one. This species and S. headsi would make up Scapteriscus s. s., the remaining species should be placed in a new genus, to be described in a phylogenetic analysis of the family (Cadena-Castañeda in press).

Specimens examined: S. oxydactylus ( Perty, 1832) , S. didactylus (Latreille, 1804) , S. borellii Giglio-Tos, 1894 , S. imitatus Nickle & Castner, 1984 , S. quadripunctatus Nickle, 2003 , S. tetradactylus ( Perty, 1832) , S. peruvianus Nickle, 2003 , S. variegatus ( Burmeister, 1838) , S. parvipennis ( Serville, 1838) , S. headsi Cadena- Castañeda, 2011.
