Type material: Holotype 3 (MNHN, #20381) Natal / C.M. [= Republic of South Africa, KwaZulu-Natal, exact locality and date unknown (C. Martin)].
Other material: RSA: 13 (NCA 87/133) Gauteng, Pretoria/Tswane, Roodeplaatdam Nature Reserve, 26°21'S, 28°21'E, sweepnetting, 9.03.1982 (I. van Rooyen, T. Marren); 13 (NCA 84/862) Mpumalanga, Bergvliet Staatsbos, Sabie, ca. 25°07'S, 30°53'E, sweepnetting, grass and ferns next to Sabie river, 19.09.1984 (A.S. Dippenaar); 13 (NCA 86/577) KwaZulu-Natal, Vernon Crookes Nature Reserve, near Park Rynie, ca. 30°18'S, 30°38'E, 25.03.1985 (R.Maartens).
Diagnosis. This species closely resemble Thyenula magna Wesołowska & Haddad 2009, but differs in the shape of the bulbus (broad in T. natalica and narrow in T. magna) and length of palpal tibia: long in T. magna (see Wesołowska & Haddad 2009, Figs 201–202) and short in T. natalica (Figs 61–62). It differs from other Thyenula in the shape of embolus that has a thin membrane (Figs 63–64).

Eye field: length 1.20, anterior width 1.95, posterior width 1.80. Cheliceral length 0.90. Clypeal height 0.15. Diameter of AME 0.70. Length of leg segments: I 1.80+1.20+1.50+1.10+0.70; II 1.60+0.90+1.00+0.80+0.60; III 1.65+0.85+1.00+1.25+0.60; IV 1.50+0.70+1.00+1.25+0.70.

Clypeus brown, chelicerae dark brown (Fig. 67). Sternum yellow, laterally brown. Abdomen greyish-yellow, ventrally with two narrow grey stripes. Dorsum brown, medially with yellow stripe. Book-lungs brownish-yellow. Spinnerets yellow. First pair of legs big and robust, all segments brown. Femora of II–IV pairs of legs brown, patellae, tibiae and metatarsi II–IV pairs ventrally brown, dorsally yellow. Tarsi II–IV pairs yellow. Palps brownish-yellow. Palpal structure as in Figs 63–64.
Female unknown.
Distribution. Republic of South Africa.
Comments. This species shares the synapomorphy of all Thyenula, viz. an embolus that forms a distal coil separated from the tegulum by the distal heamatodocha. We therefore transfer this species to the genus Thyenula (subfamily Euophryinae).
