Sánchez-Ruiz, Alexander, Brescovit, Antonio D. & Bonaldo, Alexandre B., 2020, Revision of the spider genus Nyetnops Platnick & Lise (Araneae: Caponiidae) with proposition of the new genus Nopsma, from Central and South America, Zootaxa 4751 (3), pp. 461-486 : 483

Key for the species of Nopsma n. gen. (males only)

1. Large tegulum, reaching or exceeding the palpal tibia length ( Figs 11B ; 17B )...................................... 2

- Small tegulum, not reaching the palpal tibia length ( Figs 15B ; 18B )............................................. 3

2. Elongated palpal tibia, two times the patella length ( Fig. 11B ), embolus projecting from the prolateral distal surface of the tegulum ( Figs 11 B–C; 14A), with a keel bordering the tip ( Fig. 14 D–F)............................. N. enriquei n. sp.

- Short palpal tibia, just a little greater than patella length ( Fig. 17B ), embolus projecting from the prolateral median surface of the tegulum, with three very thin, long projections on the tip ( Fig. 17 B–C, F)........................ N. armandoi n. sp.

3. Conspicuous small oval tegulum, only one-fifth the cymbium length ( Fig. 18 B–C), embolus tip with short distal projections...................................................................................... N. florencia n. sp.

- Oval tegulum one-third of the cymbium length ( Fig. 15B, D ), embolus with a keel bordering almost two-third of the tip ( Fig. 16 B–E)........................................................................ N. juchuy ( Dupérré, 2014)
