Cangoderces milani sp. nov.

Figs 5–8, 12

Type material. Holotype: male (RMNH), Wak, leaf litter, Ngaoundere Province [7°19ʹ25.94ʺN, 13°35ʹ0 1.07ʺE], Cameroon, 19 November, 1976, A. P. B. Deeleman and A. Lansberg leg. Paratypes: 2 males and 1 female, same data as holotype.

Etymology. The specific name is after Milan Rezác, an arachnologist from Crop Research Institute in Czech Republic; noun.

Diagnosis. This new species is similar to C. koupeensis Baert, 1985 and C. christae sp. nov., but can be distinguished from C. koupeensis by the semi-membranous embolus, the appearance of a falculate modifier at the base of embolus prolaterally (Figs 5 A–B, 6A–B) in the male, and the distinct shape of spermatheca (Figs 5 C, 8A–B) in the female; from C. christae sp. nov. by the pear-shaped palpal bulb and the semi-membranous embolus (Figs 5 A–B, 6A–B) in the male, and the distinct shape of spermatheca (Figs 5 C, 8A–B) in the female.

Description. Male (holotype): Total length 1.65. Prosoma 0.60 long, 0.50 wide. Opisthosoma 1.00 long, 0.55 wide. Prosoma, sternum, yellow. Legs, labium, endites and chelicerae white. Prosoma round. Six eyes, anterior row of four eyes slightly curved posteriorly, AME close together, AME and ALE contiguous, lateral eyes contiguous. Chelicerae (Fig. 7 C) longer than endites, with two teeth and four tiny granulous denticles on the promargin, and five small triangular teeth on the retromargin. Leg measurements: I 4.27 (1.25, 0.20, 1.40, 0.87, 0.55); II 3.99 (1.00, 0.20, 1.25, 0.80, 0.54); III 2.63 (0.75, 0.16, 0.80, 0.55, 0.37); IV 3.55 (1.00, 0.20, 1.10, 0.75, 0.50). Leg formula: I- II-IV-III. Opisthosoma yellowish, pear-shaped, pedicle with a small, well-developed lorum consisted of a dorsal Xshaped plate (Fig. 7 E). Male palp (Figs 5 A–B, 6A–B): Tibia with a trichobothrium dorsally; bulb whitish, pearshaped, with a blunt, semi-membranous embolus and one falculate modifier at the basal of embolus prolaterally.

Female (one of the paratypes): Similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 1.50. Prosoma 0.55 long, 0.50 wide. Opisthosoma 0.90 long, 0.55 wide. Leg measurements: I 4.05 (1.20, 0.20, 1.30, 0.85, 0.50); II 3.47 (0.90, 0.20, 1.15, 0.70, 0.50); III 2.39 (0.70, 0.14, 0.75, 0.45, 0.35); IV 3.25 (0.95, 0.20, 1.00, 0.65, 0.45). Leg formula: I-II-IV-III. Vulva (Figs 5 C, 7F, 11A–B) has a weakly sclerotized, medially and posteriorly curved plate, which decorated with several small teeth at the edge.

Variation. Total length: males 1.61–1.65 (n=3).

Distribution. Cameroon (Ngaoundere) (Fig. 12).

Discussion. Cangoderces christae sp. nov. and C. milani sp. nov. are assigned to the genus Cangoderces because of the following characteristics: Opisthosoma pear-shaped, pedicle with a small, well-developed lorum consisted of a dorsal X-shaped plate, and embolus blunt, not sclerotized. The spermatheca of C. milani sp. nov. is similar to Seychellia cameroonensis Baert, 1985 from Batouri, Cameroon. The discovery of the male S. cameroonensis in the future will be able to help confirm the taxonomic status of C. milani sp. nov.
