Material examined. — Holotype: male (SAR09_10_PST1), Malaysia, Sarawak, Bintulu Division , Sarawak Planted Forest Project ( SPFP), Tubau area, in disturbed forest in block E2K, ca 156 m, 16 Aug.2009, coll. RAD, in RMNH.

Others : male, Malaysia, Sarawak, Kapit Division , Hose Mountains, Gunung Kajang area, at side of stream 900–1000 m in disturbed forest, 6 Apr.2011, coll. RAD .

Remarks. — This species meets the definition of Telosticta , but judging by the absence of the interior projection on the superior anal appendage it may be only remotely related to the other known species of the genus. The clump of long setae on abdominal S10 of this species are remarkable (Dow, 2010: Fig. 10 ), but as short setae typically occur on the abdomen and anal appendages of the Platystictidae , perhaps it should not be too surprising that they become highly modified in some species.

The male from the Hose Mountains is teneral and very shrivelled. It bears the distinctive patch of setae on the dorsum of S10 found on the holotype of T. tubau , but the condition of the appendages and other potentially diagnostic features of the specimen are such that it is not possible to determine if it is T. tubau or some closely related but un-described species. The female of this species is unknown.
