Abstract

A new species of the genus

Poikilolaimus Fuchs,1930, viz. P. istvani sp. n., along with known species P. oxycercus (de Man, 1895) and P. jodhpurensis (Khera,1969) Sudhaus, 1980 are described and illustrated, and their relationships with other Poikilolaimus species are evaluated using morphological characters. The new species is characterized by its slender body, finely striated cuticle, slightly raised labial sensilla, isomorphic and isotopic stoma with two setose metastegostomal denticles, thick-walled vagina with four ovoid vaginal glands in proximal part of uterus, ovoid spermathecae, inconspicuous rectal glands, and males with spicules having triangular capitula and angular lamina, gubernaculum proximally crochet-shaped with distal lateral elevations, eight pairs of genital papillae and four pairs of copulatory muscle bands. The identity of P. jodhpurensis is appraised with justification, meanwhile P. oxycercus is described with minor variations.
