Embed Size px x x x x Four new species of parathelphusidcrabs are also described, viz. Terrathelphusa ovis from Sarawak , Terrathelphusa telur fromBrunei , Parathelphusa baweanensis from Bawean Islands and Parathelphusa quadrata from Lombok.

Over the last 10 years, I have examined a large amount of Javan and Bomean freshwatercrab material in various museums. While most of the new genera and species have beendescribed, for one reason or another, several have remained "in limbo" and have not beenreported. The present paper intends to resolve this. A new genus and four species ofparathelphusids are described here.

Allmeasurements are of the carapace width and length respectively. The abbreviations Gl andG2 are used for the male first and second pleopods respectively. The terminology basicallyfollows that utili sed by Ng Frontal median triangle very small but visible, lateralmargins not confluent with frontal margin.

Exopod of third maxilliped with well developedflagellum. Male abdomendistinctly T-shaped, segments strongly constricted. G 1 very stout, relatively short, directedoutwards; terminal segment about one third length of subterminal segment, cone-shapedwith sharply tapered, slender tip, distalmost part strongly setose; G2 distal segment abouthalf-length of basal segment. Gender feminine. Bott placed this species in Mainitia Bott, type species Parathelphusa Perithelphusa mainitensis Balss, , mainly on the basis of its stout Gl, although ashe commented, the external features closely resemble Terrathelphusa loxophthalma asPerbrinckia loxophthalma.

The orbits and G 1 of M. Ng, Itis obvious, however, that Bott's species does not belong to Mainitia s. Transferring M. Ng had earliershowed that Javan and Bornean species referred to Perbrinckia Bott, , by Bott actually belonged to a separate genus, Terrathelphusa Ng, see also Ng, A newgenus for M.

At this stage, it is uncertain if Torhusa is closely allied to Terrathelphusaspecies, or if the similarities between the two genera are merely a result of convergentevolution. Material examined. Nieuwenhuis, Para type - 1 male RM H I "E. Itremains uncertain if the female paratype from Kapuas is conspecific with the holotype andparatype males.

This paratype female RMNH is much smaller and is still young andit is possible that the carapace differences observed less broad and less swollen are simplydue to age differences.

Until males from the Kapuas can be collected. Nothing know'n about the biology of this species. Torhusa nieuwenhuisi Bott.
