Terrathelphusa ovis Ng, 1997

Material examined. 1 female, Baram River , Sarawak, Borneo ( NHM 1898.10.25.12), coll. C. Hose, no date .

Remarks. Specimens from Sarawak and Gunung Mulu National Park which is just east of the Baram River have been identified as Perbrinckia loxophthalma (De Man, 1892) by Bott (1970), Holthuis (1979), and Ng (1989). Ng (1997) re-examined the holotype of Geothelphusa loxophthalma and showed that its G1 structure was different from that of specimens from Gunung Mulu in northern Sarawak and referred the latter to a new species, Terrathelphusa ovis . The real T. loxophthalma was almost certainly collected from southeastern Borneo (cf. Holthuis, 1979; Ng, 1997). On the basis of the location where the present specimen was collected, it is likely to belong to T. ovis .
