Abstract

A new genus, Morasia is proposed for Dorylaimoides rhabdotus (Kreis, 1930) Thorne & Swanger, 1936 and a closely related new species, both of which are similar to Dorylaimoides but possess dissimilar tails in the two sexes. Morasia dimorphicauda n. gen., n. sp. (1.53-1.91 mm long) has 57-70 glandular organs in lateral hypodermal chords, spear 7-9 μ ventrally and 11-13 μ dorsally, spear extensions 17-20 μ, amphidelphic gonads, tail elongate conoid in female and bluntly rounded in male. Dorylaimoides constrictus n. sp. (0.80-0.90 mm long) spear 4-5 μ ventrally and 6.7 μ dorsally, spear extensions 9-11 μ, mono-opisthodelphic gonad, tail filiform and 6-9 anal body-widths long. Dorylaimoides saueri n. sp. (0.80-0.95 mm long) has spear 7 μ, ventrally and 9-10 μ dorsally, spear extensions 12-13 μ, mono-opisthodelphic gonad and tail elongate, 5-6 anal body-widths long. Dorylaimoides arcuicaudatus n. sp. (1.24-1.41 mm long) has spear 7-10 μ ventrally and 10-13 μ dorsally, spear extensions 15-16 μ, amphidelphic gonads, tail conoid, ventrally arcuate, 2.0-2.5 anal body widths long. Males of D. arcuatus Siddiqi, 1964 and D. parateres Siddiqi, 1964 are here reported for the first time. A key to the species of the genus Dorylaimoides is provided.
