Tremellia timah Gorochov et Tan, new species (Figs 9, 10, 24–34) Material examined. Holotype (male): Singapore , Bukit Timah Nature Reserve, Hindhede Nature Park, secondary forest, 29 January 2012, coll. M.K. Tan & J.J.Y. Chan. Paratypes: Singapore : 1 male, same locality as for holotype, 30 October 2010, coll. M.K. Tan; 1 male, Dairy Farm Nature Park, along Dairy Farm Loop, secondary forest, 20 January 2012, coll. M.K. Tan, R.W.J. Ngiam & W.L. Lim; 1 female, same park, along Wallace Trail, secondary forest, 10 July 2012, coll. M.K. Tan & K.H. Ong. Diagnosis. The new species differs from all the other congeners with known males (Gorochov, 1996, 2004a, 2011) in the presence of characteristic lamellar ventral lobe at the distal part of ectoparameres, that is, its ectoparameres ventrally are without any notch at the subapical part; but in Tremellia fratercula (Chopard), Tremellia mindoro Gorochov and Tremellia minahassa Gorochov, such lobe is undeveloped or almost undeveloped, and their ectoparameres ventrally are with a distinct notch at the subapical part. Without female specimens of this species, differences of the new species from Tremellia spurca Stål, described for a single female from the Philippines, are unknown. Description. Male holotype. General appearance typical of this genus (Figs 25, 26, 28). Head rostrum approximately as wide as scape. Pronotum pubescent, broader than long, widening posteriorly, with anterior and posterior margins of disc fairly straight. Fore tibia with inner tympanum (as in Fig. 9) large and oval (opened); outer one slightly smaller but also oval (opened); both tympana barely immersed; hind tibia with 4 pairs of rather long and movable dorsal spines (length of longest inner distal spine 1.5 mm), several distinctly shorter immovable spinules between them, and 6 rather long spurs (length of longest inner dorsal spur 2.0 mm). Tegmina slightly surpassing abdominal apex, with 8 oblique veins in dorsal field (3 proximal oblique veins small), with mirror broader than long and ...
