Ordo: Opiliones
Familia: Agoristenidae
Genus: Nemastygnus
Name
Nemastygnus ovalis Roewer, 1929 – Wikispecies link – Pensoft Profile
- Nemastygnus ovalis Roewer, 1929: 277, fig. 44 (♂); Kury 2003[1]: 145; (male holotype, Colombia, Cundinamarca, Bogotá, SMF RI 1005/4, examined).
Description
Penis (Fig. 1B–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)[2] transferred Prostygninae to Cranaidae. Later, in his catalogue, Kury (2003)[1] 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[3]; Pinto-da-Rocha 1996[4]; Kury 1997[5]; Pinto-da-Rocha and Hara 2009[6]).
