Remarks. The genitalia of P. costirufa were not described by Draudt (1950), so we use the opportunity to describe male and female genitalia below. He also did not designate the holotype in the text. Draudt listed two specimens from Batang, 2600 (2800) m collected on 10.v.36 and several more worn specimen from 29.iv.-25.v.1936, but D. Stüning found a specimen designated by Draudt as P. costirufa holotype in the ZFMK collection. The same specimen was pictured and called as a male in the description in Taf. II, Fig. 9 ., but actually it‘s a female, as Draudt correctly marked it on the labels.

Male genitalia ( Figs 11, 12 ). Uncus long, elongated, hook-like strongly curved, apically acute, subapical hairs long, forming a long ridge; tegumen low-positioned, rather weak and narrow; penicular lobes small, covered with long apical hairs; fultura small, pendulum-shaped, interiorly rhomboidal, anteriorly tapering and thin; vinculum small but strong, Ushaped; sacculus large, ventral process strong, blade-shaped and fused with valva; harpe strong, medium length and elongated, thorn-shaped with wider basis; valva elongated, finely S-shaped, apically broadly rounded and covered with strong setae. Aedeagus straight, medium length, tubular; coecum broader, ventral carinal bar long, sclerotised; vesica broadly sack or balloon-like, dorsally everted, terminal cornutus large and long, thorn-like, complimented with a short strip of setae, terminal half of vesica strongly tapering, tubular, medial diverticulum small, reduced.

Female genitalia ( Figs 11, 12 ). Papillae anales small, weakly sclerotised, conical in shape, densely hairy; apophyses anteriores short but strong; apophyses posteriores very short but strong; ostium bursae wide, more or less rectangular in shape; lateral processes well developed, elongated-conical in shape; ductus bursae very short but broad; cervix bursae very large, elliptical in shape, 45 degree turned and entirely heavily sclerotised, it’s middle section strongly ribbed; corpus bursae medium-sized, memranous, elongated-elliptical in shape with finely wrinkled surface and numerous signums.

Biology and distribution. Polia costirufa is a rare species, usually averaging only 3- 5 specimens per night in different types of habitats and elevations.
