Etymology

This species is named in honour of Professor V.N. Dublyansky (1930–2012), who was the instigator of complex karstological and speleological studies of the Kizil-Koba (= Krasnaya) Cave.

Material examined

Description

BODY. Body length 2.7 mm. Epicuticle smooth under optical microscope but with a reticulate surface under SEM (Fig. 47); body with sparse thin and middle-sized clothing setae with 1–3 thin distal barbs.

HEAD. Two intact antennae with 35 antennomeres, longer than body length (3.2 mm); thin subcylindrical sensillum on third antennomere in ventral position between macrosetae d and e; central antennomeres 2.1× as long as wide, apical antennomere 3.0× as long as wide; cupuliform organ occupying 1/7 of its length, with nine complex olfactory chemoreceptors; gouge sensilla 40–50 µm long in a single whorl of 10–12 sensilla on each medial and distal antennomere; a small, thin subcylindrical sensillum on third antennomere. Non-protruding frontal process with very slightly tubercular frontal macrosetae. Frontal process plain, with very slight tubercular frontal macrosetae; macrosetae along line of insertion of antennomere and x setae similar in length and with a few distal barbs (a/i/p/x with relative lengths of 29/19/24/25). Small suboval labial palps with a large subcylindrical sensillum, two guard setae, five normal setae and up to 20 neuroglandular setae.

THORAX. Thoracic macrosetal distribution: pronotum with 1+1 ma, 2+2 la 2, 2+2 lp 2,3; mesonotum with 1+1 ma, 2+2 la 2,3, 2+2 lp 2,3, 1+1 mp; metanotum with 1+1 ma, 2+2 lp 2,3, 1+1 mp. All notal macrosetae long and barbed along distal two-thirds; marginal setae similar to clothing setae, but a bit longer. Legs elongated (1.53 mm long), overpassing end of abdomen. Femur I without dorsal macrosetae; femora II–III with one dorsal macroseta inserted on distal third. No ventral tibial macrosetae. Calcars with 2–3 rows of long barbs, from base with a smooth and narrow lateral side along each calcar. Dorsal and lateral subapical tarsal macrosetae smooth. Very unequal claws, posterior claw 1.80–2.05× as long as anterior one, including a large backward overhang in posterior claw; ventral surface of claws with grooves, dorsal surface including large lateral crests with thin stripes. Posterior claw with a long, setiform pretarsal process reaching claw; anterior claw with short pretarsal processes without reaching extremity of this short claw (Figs 48–49).

ABDOMEN. Distribution of abdominal macrosetae on tergites: 1+1 post 1 on I–III; 1+1 la, 1+1 post 1 on IV; 1+1 la, 2+2 post 1,2 on V; 1+1 la, 3+3 post 1,2,3 on VI; 1+1 la, 4+4 post 1,2,3,4 on VII; 5+5 post on VIII; 8+8 post on abdominal segment IX. All post urotergal macrosetae long, robust, barbed; la urotergal macrosetae much shorter, with thin distal barbs. Urosternite I with 7+7, urosternites II–VII with 5+5, urosternite VIII with 2+2 macrosetae; all urosternal macrosetae robust, large, covered by long barbs along distal half to three-fourths. Thick stylus with almost smooth stylar setae.

SECONDARY SEX CHARACTERS. Male urosternite I without glandular g 1 setae, with subcylindrical, short and enlarged appendages with up to 15 large glandular a 1 setae, with spermatozoid fascicles. Female unknown.
