Type material. HOLOTYPE, ♂ labelled [printed in Cyrillic], [RUSSIA], “Krasnodarskiy Territory/ Apsheronskiy r-n [district], okr. st. [vicinity of village] Tverskaya [44°36′11″N, 39°36′39″E]/ 26.iv.2013, Kustov S.Yu. (ZIN). PARATYPE: RUSSIA: Krasnodarskiy Territory, Krimskiy District, vicinity of village Neberdzhaevskaya [44°50′00″N, 37°54′00″E]/ 22.v.2010, coll. Kustov S.Yu. (1 ♂, ZIN).
Recognition. Species of the P. pallidiventris-cursitans group; occiput with 1 pair of pale vertical bristles; antenna with scape and pedicel yellow, postpedicel largely darkened, about 3X longer than wide; thorax with pale to yellowish bristles; katepisternum with polished black patch; legs largely yellow, fore femur brownish on about basal half, tarsomeres narrowly brown annulated; abdomen shinning.
Description. Male. Body length 2.6 mm; wing length 2.8 mm. Head black. Occiput greyish pollinose; with 1 pair of long, pale yellow, inclinate verticals; clothed with rather long pale hairs. Ocellar tubercle greyish pollinose, with long anterior and minute posterior setae. Frons broad, somewhat broadened toward ocellar tubercle, greyish pollinose. Face very narrow, nearly 3X narrower than frons, somewhat broadened below, densely silver-grey pollinose; clypeus polished black. Antenna with scape and pedicel yellow, postpedicel yellow on about basal third, otherwise brownish, conical, 3X longer than wide; stylus black, slightly longer than postpedicel. Proboscis dark brown, short. Palpus yellowish, small, elongate ovate, silvery pubescent, with several pale bristly hairs.
Thorax with mesonotum densely yellowish grey dusted, pleuron densely silvery grey pollinose; with pale to yellowish bristles; katepisternum (= sternopleuron) with large polished black patch. Postpronotal lobe rather narrow, with 1 long seta and several short hairs. Mesonotum with 2 notopleurals (anterior short, posterior long), 1 long postalar and 4 scutellars (apical pair long, cruciate, lateral pair short); acrostichals short, arranged in 2 narrow, almost regular rows; dorsocentrals 1–2-serial, short, 2 prescutellar pairs long.
Legs largely yellow, fore femur brownish on about basal half, tarsomeres narrowly brown annulated (sharply on fore tarsus). Coxae and trochanters with yellowish setae of different lengths. Fore femur thickened; with rows of anteroventral and posteroventral yellowish setae longer on basal part. Fore tibia slender, clothed with ordinary setulae. Mid femur slightly thicker than fore femur; with double row of black ventral spinules, with long yellow posteroventral setae. Mid tibia bearing row of black ventral spinules; with long sharply pointed apical spur. Hind femur slender, with short anteroventral setae. Hind tibia slender, clothed with ordinary setulae. Tarsomeres unmodified.
Wing almost hyaline, somewhat tinged with yellow, with brownish-yellow veins. One moderately long yellow costal seta. Veins R4+5 and M1+2 convergent near wing margin, M1+2 slightly bowed; CuA2 almost perpendicular. Crossveins m-cu and r-m distinctly separated. Calypter yellow, with yellow setae. Halter yellow.
Abdomen entirely black and shining, covered with faint short whitish setae becoming longer on last segments. Segment 8 with numerous long yellowish posteromarginal setae. Terminalia (Figs 14–16) rather large, black, subglobular. Right cercus (Fig. 15) digitiform, narrow, not extending beyond apex left epandrial lamella, with rounded apex, covered with ordinary setae of different lengths; left cercus digitiform, nearly as long and broad as right cercus, slightly narrowed apically; covered with ordinary setae of different lengths. Right epandrial lamella (Fig. 14) elongate oval (ventral view), with short numerous setae over lower margin and tuft of several very long setae subapically; right surstylus rather large, digitiform, rounded apically, with some short ordinary setae. Left epandrial lamella (Fig. 16) rather subtriangular, broadly rounded apically, with short subtriangular projection on lower margin closer to base, projection covered with numerous, very long, curved, pale yellow setae.
Female. Unknown.
Etymology. The name of new species refers to the area of its origin, Krimskiy distinct, village Neberdzaevskaya.
Distribution. PALAEARCTIC: Russia (Krasnodarskiy Territory). Known only from submontane forest.
Remarks. The new species is similar to P. annulitarsis Kovalev, 1978 known from Estonia, Germany, Poland and north-western part of Russia (Chvála 2013). However, P. neberdzaensis sp. nov. has longer postpedicel, which is about 3 times as long as wide (2.5 times in P. annulitarsis); shorter stylus, which is nearly as long as postpedicel (nearly 2.0 times longer P. annulitarsis); fore femur brownish on about basal half (entirely yellow in P. annulitarsis); sharply pointed apical spur on mid tibia of the male (blunt-tipped in P. annulitarsis).
