Description.

Female. Body length 7 mm. Flagellum with 32 segments, slender and almost bristle-shaped; 1st flagellar segment 5.0 × as long as wide, ca. 15th segment square, widest segments 1.1 × as wide as long. Temple strongly and almost linearly narrowed behind eye. OED 1.1 × ocellar diameter. Frons almost smooth, with very fine granulation, shining. Face densely punctate. Clypeus moderately convex, with dense punctures. Mandible with two teeth; ventral tooth smaller than dorsal tooth and moderately bent inwards (by 45°). Malar space 0.9 × as long as width of mandibular base. 2nd maxillary palpomere strongly swollen, ovoid, about 2 × as long as wide. Genal carina reaching hypostomal carina far from mandibular base, hypostomal carina slightly elevated (about same width as 4th maxillary palpomere).

Mesosoma covered with short setae. Mesoscutum densely punctate, shining. Notaulus not impressed. Mesopleuron and metapleuron densely rugose-punctate. Juxtacoxal carina indicated by some irregular rugae. Scutellum moderately elevated, about as long as wide, with complete lateral carina and rather dense punctures. Propodeum with short-oval spiracles. Area superomedia almost rectangular, 1.4 × as long as wide; costula weakly indicated at anterior 0.3 of area superomedia. Area petiolaris slightly impressed, almost smooth, with distinct lateral carina. Posterolateral edge of area dentipara with distinct blunt apophysis. Hind coxa densely punctate, without scopa. Hind femur punctate, 4.0 × as long as wide. Tarsal claws simple, strongly curved apically (by 90°). Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 2 × distance of these veins. Vein 1cu-a interstitial.

Metasoma amblypygous. Petiole wider than high. Postpetiole slightly widened, with fine latero-median carina; median field almost smooth, with some fine punctures. Gastrocoelus weakly impressed. Thyridium oblique, 0.7 × as wide as interval. 2nd tergite 1.3 × as wide as long. 2nd tergite finely rugulose-punctate, ± dull. 3rd tergite rugulose, ± shining. Following tergites almost smooth.

Colour. Black with extended ivory colouration. Metasoma, except blackish petiole, brownish. Stripes on flagellar segments 9-14, scape ventrally, palps, mandible, except teeth, clypeus, inner orbit up to vertex, outer orbit ventrally, frontal and upper margins of pronotum, central spot on mesoscutum, subtegular ridge, spot of mesopleuron, upper division of metapleuron, apical half of scutellum, postscutellum, apophysis and area posteroexterna, narrow apical bands of all sternites and tergites, fore- and mid-coxae mainly, dorsal spot and apical margin of hind coxa, all trochanters and 1st to 3rd hind tarsomeres ivory. Legs, except coxae and trochanters, otherwise red; hind femur and tibia black in apical third. Wings hyaline, pterostigma brown.

Male. Unknown.

Remarks.

This new species resembles the type species of Cratolaboides , C. palpalis Tereshkin, 2009 (see Tereshkin (2009: 1471-1474)). It differs by more slender basal flagellar segments (1st segment 3.7 × as long as wide in C. palpalis ), ivory colouration of mesosoma and different colour pattern of the hind leg (hind femur and tibia entirely red in C. palpalis ).
