A new species of Polyonyx Stimpson, 1858, of the P. sinensis group (Crustacea: Decapoda: Anomura: Porcellanidae) commensal with a chaetopterid worm from Peninsular Malaysia Naturalis
Ng, P.K.L.; Sasekumar, A..
A new species of porcellanid crab, Polyonyx vermicola, belonging to the P. sinensis group is described from Selangor, Peninsular Malaysia. The species is an obligate commensal of tubes of the chaetopterid worm Sasekumaria selangora Rullier, 1976 (Polychaeta). Polyonyx vermicola is differentiated from all congeners by its small size, possessing a more rectangular carapace, proportionately longer carpus on the larger cheliped, strongly gaping cheliped fingers, the tips of which are turned outwards, the outer surface of each cheliped fingers lined with a row of small granules, and having the ventral margin of the third ambulatory propodus armed with strong spinules.

Ng, P.K.L..
The freshwater crabs obtained from the Lanjak-Entimau area in Sarawak, East Malaysia, Borneo, are reported upon. One new genus (Ibanum) and two new species of Potamidae (Ibanum aethes and Isolapotamon stuebingi) and a new species of Grapsidae (Geosesarma katibas) are described. The identity of Potamon (Geothelphusa) bicristatum De Man, 1899, orginally described from the upper Kapuas in Kalimantan is also clarified, and is here assigned to the new genus, Ibanum.

A new species of parathelphusid freshwater crab, Parathelphusa ceophallus, is described from Pulau Buton, a small island southeast of the island of Sulawesi in Indonesia.

On two new species of the genera Haberma and Parasesarma (Crustacea: Decapoda: Brachyura: Sesarmidae) from Papua, Indonesia Naturalis
Rahayu, D.L.; Ng, P.K.L..
Two new species of sesarmid crabs are described from the mangroves of Timika in Papua (= Irian Jaya), Indonesia. Haberma kamora spec. nov. is the second species in the genus described from Singapore, differing from the type species in the form of its male first pleopods and possessing relatively more slender ambulatory legs. Parasesarma charis spec. nov. resembles P. erythrodactyla, P. tripectinis and to some extent, P. lepidum, but has different ambulatory leg proportions and a distinctive male first pleopod structure. Parasesarma acis Davie, 1993, is regarded as a junior synonym of P. tripectinis Shen, 1940.

Parathelphusa reticulata spec. nov., a new species of freshwater crab from blackwater swamps in Singapore (Crustacea: Decapoda: Brachyura: Gecarcinucoidea) Naturalis
Ng, P.K.L..
A new species of gecarcinucoid crab, Parathelphusa reticulata spec. nov. is described from blackwater swamps in Singapore. Parathelphusa reticulata is characterized by its relatively small adult size, diagnostic colour pattern, swollen carapace physiognomy, anterolateral armature, male abdominal structure and sharply tapering male first pleopod. This species appears to be closely allied to the poorly known P. maindroni from Sumatra.

[Proceedings of the 5th Symposium on Mesozoic and Cenozoic Decapod Crustaceans, Krakow, Poland, 2013: A tribute to Pál Mihály Müller / R.H.B. Fraaije, M. Hyžný, J.W.M. Jagt, M. Krobicki & B.W.M. van Bakel (eds.)]: Fossil brachyuran crabs from the Jambusan Caves (Bau, Sarawak), collected by A.H. Everett in 1878-1879 Naturalis
Ng, P.K.L.; Cranbrook, Earl of.
Crustacean subfossils from the Jambusan Caves in Bau (Sarawak), collected by the late A.H. Everett are assigned to two relatively large species of potamid freshwater crabs (Brachyura) that are still extant in the area, viz. Isolapotamon bauense Ng, 1987 and I. consobrinum (De Man, 1899). While I. bauense is known to occur naturally in the caves, I. consobrinum is a primarily riverine species. On the basis of the available archaeological evidence, the two species were probably collected for food by early human inhabitants of Sarawak. Characters that are useful to identify the chelae and fingers of Bornean freshwater crabs are also discussed.

A new species of freshwater crab, Siamthelphusa holthuisi spec. nov., is described from eastern Thailand. This species is closely allied to Siamthelphusa improvisa (Lanchester, 1901) from southern Thailand and northern Malaysia, but can be easily separated by its different male first pleopod structure.
