Figs. 1, 3, 5 A–C, 6–7, 8A–D

Etymology. The species name comes from the Latin word malleatus (“wrought or beaten with a hammer”), in reference to the shape of the male prolateral tibial apophysis.

Types. Male holotype: Xiaojialu Village, Hongtan Station, Huaping National Nature Reserve, Guangxi Prov., N25.60931°, E109.95181°, Alt. 850m, Coll. Lihong Tu, 3 Nov. 2007. Paratypes: 2 males, 4 females, same data as holotype.

Diagnosis. Males of the two new species can be easily distinguished by the prolateral tibial apophysis stout and dentate, strongly sclerotized in T. malleatus (Fig. 7 D), but thumb-like without dentils in T. siculus (Fig. 10 D). Females are distinguished by having the median plate longer than wide in T. malleatus, and wider than long in T. siculus (Fig. 8).
