Material examined. REP. SOUTH AFRICA: 1♂, 1♀, Mpumalanga, Waterval-Boven, st. 11, 28–29.x.2002, H.W.v.d. Wolf, genitalia slide NHMO ♂ 2161, ♀ 2717 (NHMO).

Diagnosis. Externally, Cosmetra tumulata cannot be separated from C. larseni and C. Fibigeri ; all three are about the same size. In the male genitalia Cosmetra tumulata differs from C. larseni by its differently shaped cucullus of the valva, from C. fibigeri n. sp. by the broader tegumen, and from both by the larger socii. The female genitalia of Cosmetra tumulata are close to those of C. larseni , but in the former the ductus bursae is gradually widened towards the corpus bursae in its whole length, and the shape of the corpus bursae is different.

Redescription of male genitalia. Uncus consisting of one pointed process; socii large, broadest subbasally, apically bent, ending in strong spine-like process; cucullus with numerous strong spines along lower two thirds of ventral margin, apically rounded.

Redescription of the female genitalia. Apophyses posteriores and anteriores about 1.5 times the length of 8th segment; lamella postvaginalis laterally rounded, with posterior median projection, lateral ridges joined with posterior median process; ductus bursae sclerotized except at entrance of corpus bursae, narrowing posteriorly, ribbed anteriorly on right side; corpus bursae round.

Distribution. Republic of South Africa.

Biology. The food plant is unknown.

Remarks. The identity of Cosmetra tumulata is based on the figure of the female holotype given by Clarke (1958). The holotype was collected in January 1907 in the Pretoria district in Natal by A.J.T. Janse (Meyrick 1908, Clarke 1958). The male holotype of C. neka was collected in the Cape Province in March 1978 by D. & M. Davis & B. Akerbergs (Razowski & Brown 2009). Dissections of the male and female collected together in Mpumalanga by Hugo W. van der Wolf, shows that C. tumulata and C. neka represent the female and the male of the same species.
