MATERIAL. Holotype, ♂ (slides); Republic of Crimea, Karadag Nature Reserve, environs of Kurortnoe, leg. V. Martynov, 3.X.2020, under stones with ants Tetramorium sp., 44°54′45″N, 35°11′30″E (VIZR). Paratypes, 2 ♀♀ (slides); same data and place of collection as for holotype (VIZR).
DESCRIPTION. Body length 3.0– 3.9 mm; head length 0.22–0.25 mm; thorax length 1.1–1.3 mm. Head width 0.7–0.8 mm; thorax width 1.1–1.4 mm; abdominal segment IX width about 0.50–0.55 mm. General body colour whitish with golden setae and scales. Small size, elongate ateluriform shape, covered with relatively large scales, including head and coxae. Body 2.6–3.0 times longer than wide; head small, about 3.0–3.5 times wider than long. Antennae and cerci partially broken. Male pedicellus of antennae with well-developed almost triangular apophysis not reaching distal margin of the first flagellomere (Fig. 1). Articles of cerci and caudal filament only with one, two or 3–8 dorsal, ventral and lateral trichobothria. Macrochaetae simple or with apical bifurcations.
Basal annuli of flagellum also with trichobothria: the first annulum of antennal flagellum with 4–7, the second one with two, and 3–7th annuli with one trichobothrium. Mandibles with well-developed incisor and molar regions and with a row of macrochaetae along outer surface, first of which with apical bifurcation. Incisor region with five (in male, Fig. 2) or six (in female) incisives. Maxillary palps with five palpomeres. Ultimate palpomere of maxillary palps 1.2 times longer than penultimate in females and in 1.5 times in male. Ultimate palpomere with three apical sensorial papillae of usual form in both females and male (Fig. 3).
Galea of maxilla with two apical conules, one of which more rounded than the other. Apical tooth of lacinia single-top, pectinate prostheca long with about 18 (female) or 16 (male) narrow hyaline projections, five bifurcated hyaline lamellae, first of which large and perpendicular, the rest inclined, and with 3–4 simple macrochaetae and 2–3 small setae along inner margin. Perpendicular lamella in apical part with five lateral projections (Figs 3, 4). Apical palpomere of labial palp ovoid, in female about 1.3–1.4, in male 1.5 times longer than wide, with six typical sensorial papillae (Fig. 5). Undersurface of last three palpomeres of labial palps with numerous relatively shortened and thickened, slightly curved, apically bifurcated setae. Glossae divided into two pairs of lobes, shorter than paraglossae. Paraglossae with simple setae.
Lateral margins of thoracic tergites with a row of setae, two of which in the posterior corners apically bifurcated and the longest, without sensory fields. Anterior border of pronotum with numerous small setae. Posterior margin of pro-, meso- and metanotum in both female and male with 4, 5 and 7–8 thin setae, respectively (Fig. 6).
Legs quite elongate. Coxae and femora widened (Fig. 7). Ratio length to width of coxae I, II and III about 1.57, 1.35 and 1.43; femora — 1.83, 1.82 and 1.90; tibia — 3.56, 3.37 and 4.05, respectively. Apex of dorsal part of tibia I, II and III with two, femur with one lyriform spines in both female and male (Fig. 8). Tibia also with one relatively large apical spur and four ventral simple macrochaetae. Middle part of femur I, II and III with two long macrochaetae, distal ones bifid and proximal ones simple. Praetarsus with two strong claws, two small pulvilli, medial empodial claw and slightly convex small support oval platform with 3–4 transverse ribs.
Urotergites I–VIII infralaterally with 2 + 2 bifid and 3 + 3 additional simple macrosetae; inner setae more robust and longer than others. Posterior margin of urotergites I–VIII with 4–5 setulae in female and 4–6, sometimes 8–10 setulae in male. Urotergite IX with posterolateral corners protruding, with 2 + 2 apical, 4–5 + 4–5 outer and 1–2 + 1–2 inner shorter macrosetae. Urotergite X with semi-circular concave hind margin (Figs 9, 11). Ratio depth to width of concave about 0.53 in female and 0.70 in male. Apex of posterolateral angles of urotergite X with 1 + 1 long and strong macrosetae, inner and outer margin of notch with 3–4 + 3–4 macrosetae. In male, underside of tergite X with 1 + 1 groups, usually consisting of 5 pegs; opposite them, there are also 5 + 5 pegs on the inner lateral side of basal cercomeres (Fig. 9).
Urosternite I with 1 + 1 submedian small setulae. Urosternite II with one pair of submedian vesicles (Fig. 12). Urosternite III with 4–5 + 4–5 (Fig. 13), IV–VI with 5–6 + 5–6 setae in the hind margin. 1 + 1 submedian macrosetae long, apically bifurcated. Urosternite VII with one pair of pseudovesicles and with subgenital plate (Fig. 13). Subgenital plate well-developed, 1.8 times wider than long, with rounded hind margin and with single row of simple setae, apically slightly acute. Styli on urosternites VII–IX. Length ratios of styli (without apical spines) and urosternite VII about 0.58, urocoxites VIII — 0.70, urocoxites IX — 0.80, apical spines and styli — 0.24, 0.22 and 0.20, respectively (Fig 14).
Male parameres wide, 7-segmented, longer than the penis, and slightly protrude beyond the tips of the coxites IX (Fig. 10).
Ovipositor spindle-shaped, slightly shorter than styli IX, gonapophyses VIII and IX with eight divisions and acute apexes. Gonapophyses VIII and IX with acute apex. Gonapophyses VIII with numerous outer straight setae. Outer margin of gonapophysis VIII also with one or two thin long sensorial setae on 1st to 7th divisions. Outer margin of gonapophysis IX with one or two long sensorial setae on 2nd to 7th and three such setae on apical division (Figs 15, 16). Gonapophyses IX also with an inner apical spiny area. Apical part of gonapophyses IX also with well-developed oval sensorial field.
ETYMOLOGY. The name of the new species derives from the name of Crimea.
