Diagnosis

Easily distinguished from most congeners by procursus ( Figs 102-103 View 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 104-105 View Figs 102 - 107 ); from these and other congeners also by distinctive pair of round structures with concentric rings in female internal genitalia ( Figs 98 View Figs 97 - 101 , 106 View 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. 97 View 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. 97 View 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 104-105 View 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 100-103 View Figs 97 - 101 View 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 98 View Figs 97 - 101 , 106 View Figs 102 - 107 ), with median pocket between epigynum and spinnerets; internal genitalia as in Figs 99 View Figs 97 - 101 and 107 View Figs 102 - 107 .

Distribution

Known from several localities in Southwest and Centre Regions, Cameroon ( Fig. 34 View Figs 33 - 34 ).
