Diagnosis

Tiny monochromous species, distinguished from superficially similar African species ( Nyikoa limbe Huber, 2007 , some ‘ Spermophora ’ and Quamtana species) by shape of simple short procursus ( Fig. 108 View Figs 107 - 110 ), simple bulbal apophysis and embolus with slightly sclerotized distal projection ( Fig. 107 View Figs 107 - 110 ), by shape of male cheliceral apophyses (provided with one modified hair each; Fig. 109 View Figs 107 - 110 ), and by sac-like internal structure frontally in female genitalia ( Figs 69 View Figs 50-69. — 50-52 , 110 View Figs 107 - 110 ; usually visible through cuticle).

Etymology

The species name is derived from the type locality; noun in apposition.

Description

Male (holotype)

MEASUREMENTS. Total body length 1.35, carapace width 1.0. Leg 1: 7.8 (2.0 + 0.2 + 2.1 + 2.6 + 0.9), tibia 2: 1.4, tibia 3: 0.9, tibia 4: 1.2; tibia 1 L/d: 43. Distance PME-PME 90 µm, diameter PME 70 µm, distance PME-ALE 10 µm, no AME.

COLOR. Prosoma monochromous pale ochre-yellow, legs ochre yellow, without darker rings, abdomen monochromous pale grey.

BODY. Habitus as in Figs 57 and 58 View Figs 50-69. — 50-52 ; ocular area barely elevated, carapace without thoracic furrow; clypeus unmodified. Chelicerae as in Fig. 109 View Figs 107 - 110 , each distal frontal apophysis with one modified hair at tip. Sternum wider than long (0.65/0.55), unmodified.

PALPS. As in Figs 107 and 108 View Figs 107 - 110 , coxa with small ventral apophysis, trochanter with retrolateral apophysis (slightly longer than appears in Fig. 108 View Figs 107 - 110 ), procursus very simple, without hinged process, without ventral flap; bulb with large proximal sclerite, small rectangular apophysis, embolus with slightly sclerotized distal projection.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 21%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with ~20 pseudosegments, distinct distally.

VARIATION. Tibia 1 in 22 other males from Uganda, Congo DR and Cameroon: 2.3-2.6 (mean 2.4). Males from Ghana seem to have indistinguishable palps but slightly longer and more widely spaced cheliceral apophyses and slightly shorter legs: tibia 1 in 21 males from Ghana: 2.0-2.3 (mean 2.1); they are therefore assigned tentatively.

Female

In general similar to male. Tibia 1 in 34 females from Uganda, Congo DR and Cameroon: 1.6-2.0 (mean 1.8). Epigynum extremely simple, no external modification visible in dissecting microscope; only internal frontal sac-like structure visible through cuticle; pair of pockets only visible in compound microscope ( Fig. 110 View Figs 107 - 110 ). In females from Ghana, these pockets are barely visible and slightly wider apart; tibia 1 in 20 females from Ghana: 1.4-1.6 (mean 1.55).

Distribution

Widely distributed in tropical Africa (Uganda, Congo DR, Cameroon; possibly also Ghana). Figure 27 View Figs 24 - 27 shows the only record from East Africa.
