文摘

Coomansinemoides wasimi n. gen., n. sp. was collected from the soil around the roots of guava. The new genus is characterized by moderate labial sclerotisation, double guiding ring, moderately narrow odontostyle with wide aperture, smaller expanded portion of pharynx, amphidelphic reproductive system, and dissimilar tail shape in female and male. Due to the moderate labial sclerotisation and the relatively anterior position of the second pair of pharyngeal gland nuclei, the new genus has been included in the subfamily Thornenematinae. It comes closest to the genus Coomansinema, distinctly differing in having very minute labial sclerotisation, smaller and narrower odontostyle with wider aperture, shorter odontophore, smaller expanded part of pharynx, the shape of cardia and also in having different female tail shape. Coomansinemoides n. gen. is also related to Mesodorylaimus, but can be differentiated on the basis of larger stylet aperture, double guiding ring, smaller expanded part of pharynx, and by the position of second pair of pharyngeal gland nuclei which is typical of the subfamily Thornenematinae.
