摘要

Kashmira dimorphicauda gen. n., sp. n. and Aphelenchoides hypotris sp. n. are described and illustrated from freshwater stream soil in Kashmir Valley, India. Kashmira gen. n. is characterized by having dimorphic tails: coinoid-spicate tail in femaleand subcylindroid with rounded, non-spicate tip with a minute mucro in male. It belongs to the family Seinuridae. Kashmira dimorphicauda gen. n., sp. n. has females with 0.317-0.415 (0.365) mm long body, sclerotized labial framework, tubular stylet 13-15mum long lacking basal thickenings, vulva located at 77-79 percent, degenerate rectum and anus and dorsally convex-conoid tail with spicate terminus. Male has typical spicules with elongate rod-like apex directed anteriorly, well developed pointed rostrum direct ventrally and ventral limb strongly curved, about half as long as the dorsal limb. Aphelenchoides hypotris sp. n. is characterized by its shorter body length under 0.3 mm than most other Aphelenchoides spp. (hence the name), stylet 6.5-8.5 mumlong, with minute rounded basal knobs, excretory pore close to oesophageal bulb, potvulval uterine sac 18-35 mum or 2.0-3.5 vulval body widths long, tail subcylindroid, ventrally curved 17-26 (20) mum long with a pointed terminal mucro and 8-10 mum longspicules with indistinct apex and rostrum.
