Remark. Roewer’s (1959) description of W. mabweana was based on 7♀ named ‘Typus’ from DR Congo, Upemba National Park, “Mabwe, riv. est du Lac Upemba, 585 m, 1–12.VIII.1947 ” and 5♀ named ’Paratypoide’ from Upemba National Park, “Buye-Bala, affl[uent] g[auche] Muye et s[ous]-affl[uent] dr[oit] Lufira, 1750 m, 27.IX.1948 ”. As no holotype was formally selected, all original materials are regarded as syntypes and a lectotype (previously labelled ‘holotype’) is here designated. Remaining females of the material listed in Roewer (1959) have not been located and are presumed lost.

Diagnosis. The male differs from other Wadicosa species except W. enucleata and W. manubriata by a long and looped embolus. It differs from W. mabweana and W. manubriata by a weakly developed posterior retrolateral tegular process in the bulbus ( Fig. 4E View FIGURE 4 : p.rl.p, 4H: arrow). The female is similar to W. enucleata in configuration of the epigyne but differs by the cavity in W. mabweana often being less wide and the foveolae less distinct when observed under light microscope (cf. Figs 5B–C and A View FIGURE 5 as well as 6C–D and A–B).

Description. Male ( DR Congo: Mikembo). Total length 5.1. Carapace 2.80 long, 2.15 wide.

Cephalothorax ( Fig. 2D–E View FIGURE 2 ). Carapace brown to blackish with oval yellowish to brownish median field, edge somewhat jagged, in thoracic part. No lateral bands. Sides of carapace with short black pubescence. Median field with recumbent longer white pubescence, often more or less missing due to wear. Recumbent white hairs in between eyes forwards to AME. Clypeus yellowish to dark brown. Chelicerae yellowish to dark brown with sooty longitudinal markings. Sternum greyish brown.

Eyes. Width of row I 50 (slightly procurved as seen from front), row II 64, row III 80, row II–III 63. Diameter of AME 13, ALE 10, PME 24, PLE 20. Distance between AME 8, between AME and ALE 2.

Abdomen ( Fig. 2D–E View FIGURE 2 ). Dorsum anteriorly with greyish brown lanceolate stripe bordered by dark spots.

Lanceolate stripe with a large whitish to yellowish elongated patch on each side ( Fig. 1D View FIGURE 1 ). From back of lanceolate stripe and rearwards dark chevrons and transverse bars on whitish to yellowish ground. Whitish to yellowish colour due to underlying guanocytes. Venter whitish yellow with recumbent white pubescence and scattered short dark hairs. Sides light brown to blackish brown, dotted with lighter spots.

Legs (Table I). Yellowish to greyish brown with darker annulation. In dark specimens, most of Fe appear dark and other segments more or less darkened. Coxae light yellowish, more or less suffused with grey.

Palp (3B, E, 4B, E, H). Pt 0.50, Ti 0.45, Cy 1.30. Fe mostly dark grey, other segments greyish brown to yellowish, partly suffused with dark grey. Cy brownish, more or less suffused with grey, distally lighter Tegular apophysis in ventral view ( Figs 3B View FIGURE 3 , 4B View FIGURE 4 ) longer than wide, widest distally, with hook-like process in lower distal “corner”. Anterior retrolateral tegular process in retrolateral view ( Figs 3E View FIGURE 3 , 4E, H View FIGURE 4 ) comparatively long, widest proximally, obliquely cut distally. Proximal retrolateral tegular process resembling a low crest ( Fig. 4H View FIGURE 4 ). Conductor not discernible. Embolus ( Figs 3B, E View FIGURE 3 , 4B, E View FIGURE 4 ) long, looped, wide, tapering at tip.

Female ( DR Congo: Mikembo). Total length 7.6. Carapace 3.40 long, 2.60 wide.

Cephalothorax and abdomen ( Fig. 2F View FIGURE 2 ). Similar to male. Lateral bands on carapace may be present as indistinct yellowish patches with whitish hairs.

Eyes. Width of row I 58 (slightly procurved as seen from front), row II 74, row III 93, row II–III 74. Diameter of AME 14, ALE 11, PME 27, PLE 24. Distance between AME 9, between AME and ALE 2.

Legs ( Table 1). Yellowish with greyish annulation. Darker specimens with darkened legs: Fe may be mostly black with annulation of whitish hairs. Coxae yellowish, suffused with grey.

Female genitalia ( Figs 5B–C View FIGURE 5 , 6C–D View FIGURE 6 , 7B, E, H View FIGURE 7 ). Epigyne with median cavity wider than long, anteriorly covered by cuticular extension forming a transverse edge posteriorly ( Figs 5B–C View FIGURE 5 , 6C–D View FIGURE 6 , 7B View FIGURE 7 ). Anterior to the latter two foveolae, not distinctly separated when seen under light microscope ( Fig. 6C–D View FIGURE 6 ). Accessory structures close to midline, partly surrounding spermathecae ( Fig. 7E View FIGURE 7 ).

Size variation. Carapace lengths of material measured: males 2.30–3.15 (N=15), females 2.70–3.60 (N=15).

Distribution ( Fig. 10 View FIGURE 10 ). Angola, DR Congo, Equatorial Guinea, Gabon, Namibia.
