Tarsus IV 58 in length, seta e stick­like, seta f setiform, only insertion of seta d present ( Fig. 10 View FIGURES 8 – 10 ).

Anterior hysteronotal shield: greatest length 258–277, width at level of setae cp 133–139; surface with lacunae of irregular shape and with median furrow running entire length of the shield; posterior end of this furrow bifurcate as an inverted Y ( Fig. 12 View FIGURES 11 – 12 ).

Epimerites I fused as a narrow U, coxal fields I, II and III not closed. Setae ps 2 and ps 3 button­like. Spermatheca and spermaducts as in Fig. 7 View FIGURES 5 – 7 .

ETYMOLOGY: the specific designation refers to the longitudinal furrow on dorsal shields.

Differential diagnosis. The new species resembles P. bilineatus Berla, 1958 in having a longitudinal median suture on the hysteronotal shield. However, in P. fissuratus , the suture on dorsal surface of the body also spreads onto the posterior half of the prodorsal shield in the male and runs through almost the entire length of the prodorsal shield in the female ( Figs. 1 View FIGURES 1 – 2 , 3 View FIGURES 3 – 4 ). Prodorsal and hysteronotal shields in both sexes have numerous wellpronounced lacunae of irregular shape, which somewhat resemble those of Montesauria pardalis (Gaud & Mouchet, 1957) . Seta cG of genua I and II are normal, setiform (greatly thickened, blade­like in P. bilineatus ). The aedeagus in P. fissuratus is shorter and reaches only the level of adanal discs ( Fig. 5 View FIGURES 5 – 7 ). The epimerites I of male are fused as a narrow U and are not connected with epimerites II, differently from P. bilineatus , which has a narrow V connected with epimerites II by a transverse bar. The new species was collected from Turdus leucomelas , Turdidae , whereas P. bilineatus was collected from Cariothraustes canadensis (Linnaeus, 1966.), Cardinalidae .
