Remarks:Peňa-Santiago & Coomans (1996)described Tylencholaimus intermediusfrom Spain. Ahmad and Araki (2003)reported two females of this species from Japanand recently, Ahmad et al. (2009)recorded a single specimen from Korea. The present specimens from Singaporeconform well with the typespecimens as well as the Japanese and Korean specimens. It seems that this species is quite widely distributed in East and South East Asia. Recently, Andrássy (2009)transferred this species to the genus Tantunemabecause of its small amphids and shape of lip region. We have examined this species from Japan, Koreaas well as the present one from Singapore. In all these specimens, the amphids are consistently cup-shaped with slit-like aperture and a postlabial sclerotization is present. The genus Tantunemais characterized by the presence of a pore-like amphid and none of the three species presently described under this genus has post-labial sclerotozation. Hence, the placement of this species under Tylencholaimusappears more justified.
