Nops bellulus Chamberlin, 1916

Nops bellula Chamberlin, 1916: 217 , pl. 10, figs 6–8, pl. 11, figs 1–3. Female holotype from Ollantaytambo (13°15′31″S, 72°15′49″W), 2743 m, Cusco, Peru, vii.1911, Yale Peruvian Expedition (MCZ 168; examined). Roewer, 1942: 316.

Nops bellulus: Bonnet, 1958: 3114 (emendation of N. bellula ).

Remarks. The holotype is an immature female. Chamberlin (1916) described two diagnostic characters to separate it from other Nops species: the unpaired claw elongated on the legs I‒II and a small deep brown or blackish triangular dorsal spot on abdomen. However, having the anterior unpaired claws elongated and dorsally reflexed is a diagnostic character for Nopsides , Nops and Medionops , and the triangular dorsal spot on abdomen described by Chamberlin, is actually an old scar on the specimen, which was solidified and acquired a blackish brown color. The holotype also had a chevron dorsal abdominal pattern, but this has currently almost entirely disappeared, possibly due to length of time since preservation. The loss of the dorsal abdominal pattern, combined with the fact that the holotype is immature and the absence of additional material from the region, renders it difficult to separate this specimen from any other known Nops species.
