Thyenula dentatidens sp. nov.

Figs 195–199

Holotype: male, SOUTH AFRICA, KwaZulu-Natal Province, iSimangaliso Wetland Park, Mission Rock Beach Area , 28°16'S: 32°29'E, canopy fogging, Trichilia emetica , 12 May 2012, leg. J.A. Neethling & C. Luwes ( NCA 2013 /582).

Paratypes: together with holotype, 2 males ( NCA 2013 /583) .

Diagnosis. The species is related to T. magna Wesołowska & Haddad, 2009 and T. cheliceroides described above. It can be easily distinguished from those species by the form of the chelicerae which are elongated and have a characteristically long retromarginal tooth (compare Fig. 197 herein with Fig. 186 herein and Wesołowska & Haddad 2009: fig. 200).

Etymology. The specific epithet refers to the presence of a very long cheliceral tooth.

Description. Measurements. Cephalothorax: length 3.4–4.1, width 2.6–3.1, height 1.5–1.6. Abdomen: length 2.9–4.3, width 2.0–3.5. Eye field: length 1.6–2.0, anterior width 2.4–2.8, posterior width 2.3–2.7.

Male. General appearance as in Fig. 195 . Medium sized to large spider. Carapace oval, high, brown with darker margins, eyes surrounded by black rings, fovea clearly visible. Some brown hairs on carapace, long bristles in vicinity of eyes. Clypeus low, dark. Chelicerae very large, with two small promarginal teeth, long retromarginal tooth and long fang ( Figs 196, 197 ), dorsal surface of chelicerae very dark, with metallic shine. Labium and endites brown with whitish tips, sternum light brown. Abdomen oval, dorsum covered by mosaic of dark brown spots on creamy whitish background, with light serrate belt median passing into chevrons posteriorly. Venter yellowish tinged with grey. Some brown hairs on abdomen. Spinnerets light grey. First pair of legs longest, brown, femora with black streak on prolateral surface, tibiae blackish, clothed in long dense black hairs ventrally. Other legs light brown, basal parts of femora slightly lighter. Leg hairs and spines brown. Pedipalps relatively small, their femora long and thin. Palpal organ as in Figs198, 199 , proximal lobe of bulb absent.

Female unknown.

Distribution. Only known from the type locality.

Remarks. These specimens were collected from the canopy of Trichilia emetica by fogging.
