| Abstract |
The free-living nematode genus Metachromadoroides Timm, 1961 (Desmodorida: Desmodoridae) is rediscovered after a gap of 60 years from the Bay of Bengal mudflats. Two new species viz., Metachromadoroides champensis sp. nov., distinguishable from congeners by the presence of 14–19 pairs of precloacal supplements and two pairs of post-anal ventral protuberances on tail, and Metachromadoroides hamatus sp. nov. distinguishable from congeners by the presence of arcuated spicules with distal hook, and gubernaculum with dorsal apophysis distally bent, are described herein with light microscopic images and illustrations. Comparison with congeners of the genus Metachromadoroides and an identification key to species based on males are also provided. |
