Diagnosis

Easily distinguished from most known congeners (especially from N. subtilissima Simon, 1890 which has a similar male palp) by shape of male cheliceral apophyses ( Figs 60-61 View Figs 58 - 62 ); from N. russellsmithi Huber, 2002 (which has similar male chelicerae) by shorter embolus and presence of procursus ( Figs 58-59 View Figs 58 - 62 ). From other species by shapes of bulbal projections (both projections of same length in N. toliara Huber & El Hennawy, 2007 ) or by shape of procursus (larger and not pointed in N. minuta (Berland, 1919) and N. namibiae Huber, 2000 ). Females are not easily distinguished (epigynum wider in N. namibiae , narrower in N. minuta ; similar in other species).

Etymology

The name is a noun in apposition, derived from the type locality.

Description

Male (holotype)

MEASUREMENTS. Total body length 1.2, carapace width 0.50. Leg 1: 2.96 (0.80 + 0.20 + 0.80 + 0.73 + 0.43), tibia 2: 0.67, tibia 3: 0.50, tibia 4: 0.80; tibia 1 L/d: 12. Distance PME-PME 35 µm, diameter PME 40 µm, distance PME-ALE 25 µm, diameter AME 20 µm, distance AME-AME 20 µm.

COLOR. Entire animal ochre-yellow to ochre-grey.

BODY. Habitus as in Figs 53-54 View Figs 53 - 57 ; ocular area not elevated; carapace without median furrow; clypeus more sclerotized at rim and medially slightly protruding; sternum about as wide as long (0.38/0.37), with distinct humps near leg coxae 1. Chelicerae as in Figs 60-61 View Figs 58 - 62 , with distinctive pair of frontal apophyses; with very fine stridulatory ridges.

PALPS. As in Figs 55-56 View Figs 53 - 57 and 58-59 View Figs 58 - 62 , coxa and trochanter unmodified, femur with small retrolatero-ventral apophysis, tarsus with small pointed procursus; bulb with long ventral process and short membranous dorsal embolus.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 67%; prolateral trichobothrium apparently absent on tibia 1, present on other tibiae; tarsus 1 with ~6 pseudosegments.

VARIATION. Tibia 1 in 5 other males: 0.63-0.73 (mean 0.69).

Female

In general similar to male but clypeus, sternum, and chelicerae unmodified; tibia 1 in 5 females: 0.50- 0.60 (mean 0.53). Epigynum simple oval sclerotized area consisting of large anterior and smaller posterior plate; internal structures poorly visible through cuticle ( Fig. 57 View Figs 53 - 57 ); unclear if complex internal structures are part of anterior plate (as appears in dorsal view; Fig. 62 View Figs 58 - 62 ) or posterior plate (as appears in ventral view); anterior plate with transversal ridge apparently connected to median pocket. Pore plates not seen ( Fig. 62 View Figs 58 - 62 ).

Distribution

Known from two localities in the North Region of Cameroon ( Fig. 25 View Figs 25 - 26 ).
