A taxonomical revision of the Korean species of family Belonolaimidae has been undertaken. Twenty three species belonging to four different genera under two subfamily were reported from Korea hiteroto. Among them Tylenchorhynchus martini to T. annulatus. Merlinius acuminatus, M. brevidens, M. joctus, M. lenorus, M. nothus and M. koreanus to genus Geocenamus. M. clavicaudatus, M. macrurus, M. socialis to genus Amplimerlinius and Quinisulcius capitatus to Tylenchorhynchus capitatus were synonymized respectively. The keys of the each genera were proposed for identification. Distribution, host plants and photograps were included.

A new species, Geocenamus seonunensis n. sp. and an unknown species, Geocenamus processes (Siddiqi, 1979) Brzeski, 1991 were newly reported from Korea. The Korean specimens closely related to G. myungsugae Choi & Geraert, 1993 but differ from G. myungsugae in having; Lip region set off by constriction and much longer stylet (Lp region is button-like , set off, stylet 22~$27{\mu}$m in G. myungsugae). It further differs from G. tumensis (Skwiercz, 1984) Brzeski, 1991 in having spermatheca rounded, stylet much longer, from G. superbus (Allen, 1955) Fortuner & Luc, 1990 in having tail terminus annulated, from G. brevicaudatus (Peng & Hunt, 1995) Brzeski, 1998 in having much longer stylet, from G. longus (Wu, 1969) Tarjan, 1973. in having smaller number of longitudinal striae. Another Korean specimens are well corresponded with Geocenamus processus (Siddiqi, 1979) Brzeski, 1991 ex- cept male tail tip which is not flagellum-like.

Two new species of Tylenchorhynchus Cobb, 1913 from sugar cane fields in Sudan, T. sudanensis and T. elamini are described and illustrated. T. sudanensis is characterized by rather medium body size female, L= 0.692 mm long with rather medium stylet length of 20 - 23 ${\mu}m$. While T. elamini is characterized by medium body size female, L = 0.61 - 0.78 mm long, medium stylet length of 16 - 19 ${\mu}m$. Different characters of two new species are discussed. In addition, vital measurements and brief descriptions of two species are presented.
