Material examined. - Type material of C. oblitus Sharp : 1 male (holotype) - “ Singapore ”, “ Type ” ( BMNH). Type material of C. andamanicus Régimbart : 1 male (lectotype) -: “Ills Andaman”, “Cotype”, “ Copelatus andamanicus Rég. Cotype ”, “ Lectotype ” ( MNHN) .

Additional material: 44 specimens - Central catchment area - 11 ex., Nee Soon Swamp Forest , puddle on track, 16 Dec.1996, coll. L. Hendrich ( CBH, ZRC) ; 16 ex., MacRitchie Reservoir , 21 Apr.1997, coll. M. Balke & L. Hendrich & C. M. Yang ( CBH, ZRC) ; 1 ex., Lower Peirce Reservoir , after the concrete water runoff, 22 Apr.1997, 230a, coll. H. K. Lua ( ZRC) . Bukit Timah – 6 ex., Bukit Timah Nature Reserve , coll. C.F. Lim ( ZRC) ; 1 ex., at pipeline, MTB track, swampy area near pond, 9 Apr.1997, coll. L. Hendrich ( CBH) ; 4 ex., MTB track at pipeline, 22 Dec.2001, coll. M. Balke & C. M. Yang ( CBH) . Other areas - 1 ex., Sembawang Senoko , mud track, 10 Jan.1992, 177 b, coll. C. M. Yang & K. L. Yeo ( ZRC) ; 4 ex., ditch on grassy patch near road, Singapor gun club, close to Bukit Timah MTB track, 22 Dec.2001, coll. M. Balke & C. M. Yang ( CBH) .

Distribution. – India [Andaman Islands], Japan [Yaku-shima and Ryukus Islands], Malaysia [ Sarawak], Taiwan ( Satô, 1985, 1990) and Singapore ( Vazirani, 1977). The record for Indonesia: Sulawesi ( Balfour-Browne 1939a) needs to be confirmed.

Ecology. – The species is found among leaf litter, roots and submerged plants of very small, temporary, shallow puddles in or near forested areas. The species seems to be restricted to the second growth forests of the Central Catchment Areas and Bukit Timah Nature Reserve.
