详细

A new genus of nematodes, Valvaelaimoides gen. n., from the family Linhomoeidae Filipjev, 1922 has been validated. The genus is characterized by very large and circular amphidial fovea with edges strongly sclerotized, as well as a rather complex vulva structure of the pharynx bulb. The new genus includes two species: Valvaelaimoides macramphis sp. n. (type species) and Valvaelaimoides leptus sp. n. Their illustrated description has been given. V. leptus sp. n. is distinguished from V. macramphis sp. n. by a shorter body, relatively longer cephalic setae, and shorter spicules.
