The new species <em>P. brevisetosus</em> sp. n. resembles to <em>P. pandispiculatus </em>(Hopper, 1961) but differs from it by the longer body, absence of somatic and cervical setae, more wide labial region, longer cephalic setae and longer spicules, and <em>P. areniculus </em>sp. n. resembles to <em>P. macrodentatus</em> (Timm, 1961) but differs from it by the longer body, relatively shorter cephalic setae, absence of knob-like swellings at base of dorsal tooth in stoma and presence of small piece in spicular apparatus of males.</p> ER -
