Figs 146–153 View FIGURES 146–153

Holotype: male, SOUTH AFRICA, Mpumalanga Province, Mariepskop Forest Reserve , 24°35'S: 30°53'E, tree beating, afromontane forest, 22 May 2005, leg. J. Horn ( NCA 2010 /3937). GoogleMaps  

Paratypes: same locality, litter and bushes, 2 males, 1 female, 17 November 2012, leg. P. Jałoszyński ( MRAC)   .

Diagnosis. The male is similar to R. bellus   and R. tuberatus   described above. It differs from R. bellus   in the clearly wider and shorter embolus, and shorter proximal lobe of the bulb. It may be distinguished from R. tuberatus   by the absence of a ventral process on the tibia, by the bulb being narrower than the cymbium (wider in R. tuberatus   ) and the shorter embolus. The female differs from other Rumburak spp.   by the lack of a ridge between epigynal depressions.

Etymology. The specific name is Latin meaning masculine, courageous.

Description. Measurements (male/female). Cephalothorax: length 2.3–2.5/2.4, width 1.7–1.9/1.9, height 1.0–1.4/1.1. Abdomen: length 1.9–2.3/2.7, width 1.4–1.7/2.2. Eye field: length 1.1–1.2/1.2, anterior width 1.6–1.8/ 1.7, posterior width 1.5–1.7/1.6.

Male. General appearance as in Figs 146, 147 View FIGURES 146–153 . Carapace oval, high, sloping posteriorly, brown, ocular area slightly darker, black rings around eyes. Delicate translucent hairs on carapace, brown bristles on ocular area, denser at anterior eyes. Clypeus, “cheeks” and chelicerae brown, anterior margins of endites light, sternum yellow. Chelicerae as in Fig. 148 View FIGURES 146–153 . Abdomen ovoid, yellowish grey, anterior margin dark, dorsum with brownish orange median streak anteriorly and chevrons posteriorly ( Fig. 146 View FIGURES 146–153 ), sides light with small brownish patches, venter yellow or tinged with grey. Some brown bristles on dorsum. Book-lung covers brown, spinnerets yellowish. First pair of legs brown, only tarsi yellow, patellae and tibiae with long brown hairs ventrally. Other legs light yellow, only femora grey. Pedipalps brownish, cymbium darker, long white hairs on tip of palpal tibia dorsally. Palpal organ as in Figs 149, 150 View FIGURES 146–153 , basal part of embolus wide, length of terminal apophysis equal to embolus length.

Female. General appearance as in Fig. 151 View FIGURES 146–153 . Coloration similar to male, but slightly lighter. Dorsum of carapace clothed in brown hairs, some white hairs near eyes. Abdomen swollen, dorsum grey with median serrate yellow streak, sides and venter yellowish with small grey markings. Legs yellow, bearing brown hairs. Epigyne with two round depressions close to each other ( Fig. 152 View FIGURES 146–153 ). Internal structure as in Fig. 153 View FIGURES 146–153 .

Distribution. Known only from the type locality.

Genus Tanzania Koçak & Kemal, 2008  

Replacement name for Lilliput Wesołowska & Russell-Smith, 2000  

Type species: Lilliput mkomaziensis Wesołowska & Russell-Smith, 2000  

Description. Diminutive (length 1.3–3 mm) epigeic spiders, collected most often in litter. The male palp lacks a tibial apophysis; the embolus is coiled, ribbon-like, flattened at tip. The epigyne is relatively large, with median a septum and spiral sclerotized flanges surrounding the copulatory openings. The spermathecae are large and spherical. Males have a clearly marked abdominal pattern. The presence of a single very long curved seta on the clypeus is characteristic.

Distribution. Poorly known, but probably widespread in the Afrotropical Region.
