Diagnosis

Easily distinguished from most congeners by procursus ( Figs 102-103View Figs 102 - 107; strongly bent towards ventral; with large hinged ventral process); from similar (East African) species ( S. morogoro Huber, 2003  ; S. usambara Huber, 2003  ; S. masisiwe Huber, 2003  ; cf. figs 222, 239, 245 in Huber 2003b) by long apophyses on male chelicerae ( Figs 104-105View Figs 102 - 107); from these and other congeners also by distinctive pair of round structures with concentric rings in female internal genitalia ( Figs 98View Figs 97 - 101, 106View Figs 102 - 107).

Etymology

Named for the Cameroonian writer Alexandre Biyidi Awala (1932-2001), known as Mongo Beti.

Description

Male (holotype)

MEASUREMENTS. Total body length 2.2, carapace width 0.8. Leg 1: 21.5 (5.2 + 0.3 + 5.2 + 7.9 + 2.9), tibia 2: 3.3, tibia 3: 2.0, tibia 4: 2.9; tibia 1 L/d: 73. Distance PME-PME 220 µm, diameter PME 95 µm, distance PME-ALE 35 µm, absent.

COLOR. Carapace ochre-yellow with black lateral margins and light brown median mark ( Fig. 97View Figs 97 - 101), ocular area with dark band between eye triads, clypeus with a few black spots, sternum whitish, legs ochreyellow, with black spots on femora proximally, black patellae and tibia-metatarsus joints, dark rings subdistally on femora and tibiae (unusually far from tip), abdomen ochre gray with black marks dorsally and laterally.

BODY. Habitus as in Fig. 97View Figs 97 - 101; ocular area barely elevated, each triad on low hump; carapace without median furrow; clypeus unmodified; sternum wider than long (0.58/0.42), unmodified. Chelicerae as in Figs 104-105View Figs 102 - 107, with pair of proximal lateral apophyses and long frontal apophyses provided with three modified hairs each at tips, without stridulatory ridges.

PALPS. As in Figs 100-103View Figs 97 - 101View Figs 102 - 107, coxa unmodified, trochanter with short retrolatero-ventral apophysis, femur unmodified, procursus strongly bent towards ventral, with complex tip and large ventral hinged process; bulb with long, weakly sclerotized embolus and short, hooked apophysis.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 8%; prolateral trichobothrium absent on tibia 1, present on other tibiae. Tarsus 1 with>20 pseudosegments, only distally fairly distinct.

VARIATION. Tibia 1 in 12 other males: 4.1-5.5 (mean 4.9). Some specimens with additional indistinct dark ring on each femur and tibia.

Female

In general similar to male; tibia 1 in 10 females: 3.6-4.6 (mean 4.2). Epigynum light brown area with pair of distinctive internal structures with concentric rings visible through cuticle ( Figs 98View Figs 97 - 101, 106View Figs 102 - 107), with median pocket between epigynum and spinnerets; internal genitalia as in Figs 99View Figs 97 - 101 and 107View Figs 102 - 107.
