A new nematode species, Rhabdochona (Globochona) rasborae sp. n. (Rhabdochonidae), is described from the intestine of the freshwater cyprinid fish (sidestripe rasbora) Rasbora paviana in the Bangbaimai Subdistrict, Muang District, Surat Thani Province, southern Thailand. It differs from other representatives of the subgenus Globochona which possess eggs provided with lateral swellings in having a spinose formation at the tail tip of both sexes and in some other morphological features, such as the body length of gravid female (8.6-23.7 mm), presence of two-three swellings on the egg, eight anterior prostomal teeth, length ratio of spicules (1 : 5.3-6.7) and arrangement of male genital papillae. This is the third nominal species of Rhabdochona and the second species of the subgenus Globochona reported from fishes in Thailand. The three species of Rhabdochona recently described from fishes in Pakistan, viz. R. annai, R. bifurcatum, and R. pakistanica, are considered to be species inquirendae.
