Abstract

One genus and two new for science nematoda species, found in coral reefs of coast area of Vietnam are described. Minisigma gen. nov. characterized by the finely annulated cuticle with lateral files in the form of two parallel sclerotized ridges. At both edges of lateral files there are cuticular pores. Pharyngostoma armed with large dorsal tooth and two small subventral teeth. The fovea of amphids in the form double-turn spirals. There are ocellius. Pharynx bulb elongate-oval, poorly expressed. In front of cloaca four S-shaped sclerotized supplements. Minisigma vietnamicum gen. nov., sp. n. is described and illustrated Hofmaenneria longisetosa sp. n. in body size is close to H. keoladensis Khan, Husain, Sultana, 2005 and H. niddensis Gerlach, Meyl, 1957. It differs from first species by relatively shorter pharynx, relatively shorter tail, longer outer labial setae. It differs from second species by thinner body, relatively shorter tail, longer outer labial setae and shorter spicules.
