Spermophora Cam 64: Dimitrov, Astrin & Huber 2012 (DNA sequence data). 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 ), simple bulbal apophysis and embolus with slightly sclerotized distal projection ( Fig. 107 ), by shape of male cheliceral apophyses (provided with one modified hair each; Fig. 109 ), and by sac-like internal structure frontally in female genitalia ( Figs 69 , 110 ; usually visible through cuticle). Etymology The species name is derived from the type locality; noun in apposition. Type material Holotype , in ZFMK ( Ar 8764 ) . Paratypes 4 ♂♂ , 11 ♀♀ , in ZFMK ( Ar 8765 ) .

Material assigned tentatively GHANA : Central Region : 24 ♂♂ , 32 ♀♀ (7 vials), in MRAC ( 217692, 95, 217705, 15, 20, 24, 29 ), Kakum forest ( 5°20’N , 1°23’W ), fogging in primary and secondary forest , 14-19 & 25 Nov. 2005 ( R. Jocqué , D. de Bakker , L. Baert ) . 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 ; ocular area barely elevated, carapace without thoracic furrow; clypeus unmodified. Chelicerae as in Fig. 109 , 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 , coxa with small ventral apophysis, trochanter with retrolateral apophysis (slightly longer than appears in Fig. 108 ), procursus very simple, without hinged process, without ventral flap; bulb with large proximal sclerite, small rectangular apophysis, embolus with slightly sclerotized distal projection. Figs 107-110. Spermophora kyambura sp. nov. 107-108. Left ♂ palp, prolateral and retrolateral views. 109. ♂ chelicerae, frontal view. 110. ♀ genitalia, cleared dorsal view. b: genital bulb; e: embolus; ep: epigynal pockets; pr: procursus. Scale lines: 0.2 mm (109-110), 0.3 mm (107-108). 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 ). 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 shows the only record from East Africa.
