Thyenula tenebrica sp. nov.

Figs 225–228

Holotype: female, SOUTH AFRICA, Eastern Cape Province, Stormsriver, Tsitsikamma National Park , 34°01'S: 23°53'E, coastal forest, leaf litter, 5 December 2012, leg. J.A. Neethling ( NCA 2013 /655).

Diagnosis. This species is characterized by the very dark coloration of the body. The female epigyne is similar to that in T. wesolowskae Zhang & Maddison, 2012 but differs by the presence of the accessory glands (lack in the latter species), the clearly narrower and shorter seminal ducts and the bean shaped spermathecae (versus rounded in T. wesolowskae ).

Etymology. The specific name is Latin for dark and refers to the colouration of this spider.

Description. Measurements. Cephalothorax: length 2.4, width 2.0, height 1.1. Abdomen: length 2.8, width 2.3. Eye field: length 1.2, anterior and posterior width 1.5.

Male unknown.

Anterior eyes encircled by small scales, fawn from above and whitish below, some reddish hairs on eye field anteriorly, grey hairs on thoracic part. Clypeus clothed in white hairs. Chelicerae dark brown, promargin with two teeth, retromargin unident. Sternum and mouth parts brown. Abdomen black with a few pairs of very small whitish spots medially ( Fig. 225 ), faint dark hairs on abdominal dorsum, on sides light narrow streak, venter dark with four lines composed of light dots. Spinnerets black. Femora of all legs black (dorsal surfaces slightly lighter), other segments light brownish with black rings and markings. Leg hairs thin, spines dark.
