Nemastygnus ovalis Roewer, 1929 Fig. 1

Nemastygnus ovalis Roewer, 1929: 277, fig. 44 (♂); Kury 2003: 145; (male holotype, Colombia, Cundinamarca, Bogotá, SMF RI 1005/4, examined).

Description.

Penis (Fig. 1 B–C; holotype): truncus with three pairs of bifid setae (basal, subdistal lateral and distal ventral). Ventral plate with rounded lobe on corners, two dorso-basal pairs of small single branched setae, a ventral distal pair of small single branched setae and a ventral median bifid setae. Glans dorsally projected, slender, with a small ventral crest and a long dorsal crest. Stylus smooth.

Taxonomical note.

Nemastygnus was originally placed in Gonyleptidae , Prostygninae . Kury (1994b) transferred Prostygninae to Cranaidae . Later, in his catalogue, Kury (2003) transferred Nemastygnus to Gonyleptidae , Metasarcinae without examining the type material. We herein propose the transfer of Nemastygnus to Agoristenidae Leiosteninae , based on characteristics of body and male genitalia, viz., filiform leg I, saddle-shaped ocularium, pedipalpus with well developed setae in ventral row of femur (basalmost longest, size including socket about length of pedipalpal femur) and prolateral/retrolateral of tibia and tarsus, penis with typical ventral plate and bifid setae ( Kury 1993; Pinto-da-Rocha 1996; Kury 1997; Pinto-da-Rocha and Hara 2009).
