Nyetnops Platnick & Lise, 2007


Genus Nyetnops Platnick & Lise, 2007 

Type species: Nyetnops guarani Platnick & Lise, 2007  .

Other species included. Nyetnops naylienae  n. sp., N. lachonta  n. sp. and N. buruti  n. sp.

Diagnosis. Members of Nyetnops  can be distinguished from non-nopine genera by having tarsi subsegmented ( Figs 2AView FIGURE 2; 5G, I, KView FIGURE 5); and from other two-eyed nopine genera by lacking all three membranous modifications on anterior legs: crista, gladius and arolium ( Figs 2View FIGURE 2 A–B; 5H; 6A–B). In addition, males of Nyetnops  can be distinguished from other nopine genera by having an extraordinary elongated copulatory bulb with limits between tegulum and embolus being discerned only by differences in the cuticle ( Figs 3View FIGURE 3 A–B, G–H; 6D–G).

Description. See Platnick and Lise (2007): 4–9. Complementary description: Female (IBSP 154310). External female genital area with anterior and posterior plates sclerotized ( Figs 1HView FIGURE 1; 4HView FIGURE 4), sclerotization around spiracles (ess) not reaching the anterior side of anterior spiracles ( Fig. 10View FIGURE 10 A–B). Internal genitalia consisting of transverse, anteriorly directed, slightly sclerotized receptaculum (re) with concave proximal margin, and a membranous uterus externus that extends anteriorly over the receptaculum ( Figs 1IView FIGURE 1; 4IView FIGURE 4; 10View FIGURE 10 A–B).

Distribution. Peru, Bolivia and Brazil ( Fig. 10CView FIGURE 10).
