BODY. Length 3.0 and 3.1 mm in two males, 3.5‒4.8 mm in nine females, 2.2 and 2.3 mm in two juveniles ( Table 1 ). Epicuticle smooth under optical microscope but slightly reticulated at high magnifications with irregular polygonal structures of variable size. Body with short to middle-sized smooth clothing setae.

HEAD. Antennae with 25‒30 antennomeres in 10 complete intact antennae; antennae 0.6‒0.8 × length of body in adults and 0.9× in juveniles ( Table 1 ). Medial antennomeres 1.4× as long as wide, apical antennomere 2.3× as long as wide. Cupuliform organ with about ten oviform sensilla of types I and II and an unknown number of tree-shaped sensilla (type III) in this olfactory complex ( Fig. 27 ). Distal and central antennomeres with five whorls of barbed macrosetae and scattered smooth setae, plus single distal whorl of about ten short, thin gouge sensilla 15‒18 µm long ( Fig. 28 ). Proximal antennomeres with typical trichobothria, plus small and slightly shallow, 7 µm long sensillum on 3 rd antennomere in ventral position.

Plain frontal process with one frontal and two posterior macrosetae with length ratios a/p 45/30; three macrosetae along each side of insertion line of antennomere and setae x with thin distal barbs; length ratios a/i/p/x 28/38/27/ 30 in paratype ♀ 05 IBB-92102. Occiput of the head dorsally with 6+6 macrosetae, including 3+3 la, lp and mp macrosetae, longer than clothing setae and with few distal barbs. Large suboval labial palps each with microsensillae on the surface, small shallow latero-external sensillum, two guard setae, and up to ten clothing setae in anterior position, with up to 120 neuroglandular setae in medial and posterior positions, in holotype.

THORAX. Thoracic macroseta distribution: pronotum and mesonotum with 1+1 ma, 1+1 la, 2+2 lp macrosetae; metanotum with 1+1 ma, 2+2 lp macrosetae. All macrosetae long and slightly thickened, with barbs along distal five-fourths of each seta; marginal setae up to twice as long as and thicker than clothing setae, well barbed near base ( Fig. 29 ). Metathoracic legs reaching abdominal segment VI, about 0.3‒0.4 × as long as body length ( Table 1 ). Femora II–III each with one long, thick dorsal macroseta with barbs along distal half and with two long ventral macrosetae. Calcars with long barbs along one side. Tibiae I‒III with two short, thick ventral macrosetae with barbs along distal two-thirds. Two rows of ventral barbed setae. Three smooth, dorsal distal tarsal setae longer than rest. Subequal claws with large basal half with tiny dorsal spines and distal half curved and thinner. Laminar processes of pretarsus smooth on dorsal side and with long, thin, ending curved and with enlarged on ventral side.

ABDOMEN. Distribution of abdominal macrosetae on tergites: 1+1 post 1 on I‒II; 2+2 post 1–2 on III; 4+4 post 1–4 on IV–VII; 5+5 post 1–5 on VIII; and 7+7 post 1–7 on abdominal segment IX. All tergal abdominal macrosetae long, thick and short, with thin barbs along the distal fourth-fifths.

Urosternite I with 8+8 macrosetae ( Figs 30−31 ); urosternites II–VII with 4+4 macrosetae; urosternite VIII with 1+1 macrosetae; urosternal macrosetae of medium length or longer, with long barbs in single row along distal one-fourth to three-fourths. Stylus with apical seta, subapical seta and ventromedial seta with few long barbs arranged in one row along distal half to four-fifths. Cerci 0.6‒0.85 × length of body, with 5 and 7 primary articles, not counting multi-divided basal article ( Table 1 ). Each primary article covered with unarranged whorls of barbed macrosetae and typical whorl of short setae with tiny distal barbs.

SECONDARY SEX CHARACTERS. Female first urosternite with slightly thickened cylindrical appendages, each bearing microsensillae and 32‒64 glandular a 1 setae in a distal field ( Table 1 ; Fig. 31 ). Male first urosternite with short subcylindrical appendages, each bearing microsensillae and 19‒22 glandular a 1 setae in distal field ( Table 1 ; Fig. 30 ).

Type locality

Kyrgyzstan, Kara Alma Village, Suzak Province, Jalal-Abad Region, 41º15′59″ N, 73º22′43″ E, 1661 m a.s.l.

Habitat

The morphological features and locations where Turkmenocampa edaphica Sendra & Sánchez-García sp. nov. has been found are congruent with those of a soil-dwelling species. In all cases, the species has been found in endogean habitats: under stones or among tree roots, always in humid places at 1661 m a.s.l. and 1851 m a.s.l., which is an average elevation for this mountainous country.

Phyletic affinities

Turkmenocampa edaphica Sendra & Sánchez-García sp. nov. is the second known species of a genus known previously from a troglobitic species inhabiting Kaptarhana Cave in Eastern Turkmenistan, Turkmenocampa mirabilis Sendra & Pavel, 2017 , which is characterized by a Plusiocampinae pattern of macrosetae on the thorax and abdomen. Turkmenocampa also has a unique pretarsus consisting of subequal claws comprised of a large basal half with tiny dorsal spines, a thin, curved distal half and lateral laminar processes with long ventral barbs. Turkmenocampa mirabilis shows slight troglobiomorphic features: 30–32 antennomeres; up to twenty oviform sensilla on the cupuliform organ; gouge sensilla 18–26 μm long; middle antennomeres 2–2.5× as long as wide; legs slightly elongated; metathoracic legs reaching abdominal segment VIII; and much longer than wide appendages of the first urosternite, both in males and females ( Sendra et al. 2017). However, T. edaphica Sendra & Sánchez-García sp. nov. shows body characters of a soil dweller: 25–30 antennomeres; up to ten oviform sensilla on the cupuliform organ; middle antennomeres 1.4× as long as wide; gouge sensilla 15–18 µm long; metathoracic legs reaching abdominal segment VI; and much longer than wide appendages of the first urosternite in both females and males. Turkmenocampa edaphica Sendra & Sánchez-García sp. nov. differs from T. mirabilis by the greater thickness of barbed marginal setae and by the greater number of glandular a 1 setae on the first urosternite appendages in females: with 32–64 in T. edaphica Sendra & Sánchez-García sp. nov., 12–21 in T. mirabilis .
