( Figs 3-7 ) H o l o t y p e: ( ♀ ) SW Georgia , Kintrishi NP, 1634m asl., 41.44535308°N 41.05384144°E , MT 12, 24.viii.-7.ix.2018, leg. G. Japoshvili ( Tbilisi ). D e s c r i p t i o n: ♀ : Body length 9.2 mm . Flagellum with 33 flagellomeres, filiform; 1 st flagellomere 3.1× longer than wide; preapical flagellomere about square. Head dorsally 2.4× wider than long. Temple strongly and almost linearly narrowed behind eye. Distance between lateral ocellus and eye 0.55× and between lateral ocelli 1.1× their diameter. Face with convergent sides ventrally, finely rugose-punctate, minimal width 0.85× frontal width and 0.55× eye length. Malar space 0.4× as long as width of mandibular base. Genal carina straight, not bent outwards ventrally, reaching hypostomal carina; both carinae low. Figs 3-7: Casinaria georgiana RIEDEL nov.sp. HT: ( 3 ) face, ( 4 ) head from dorsal, ( 5 ) mesosoma from lateral, ( 6 ) propodeum from dorsal, ( 7 ) metasoma from dorsal. Side of pronotum with longitudinal striation ventrally. Mesopleural disc granulate and partly with fine rugose punctation; speculum with microsculpture, but shining; dorsal impression with strong longitudinal striae. Epicnemial carina low ventrally. Propodeum coarsely rugose, without distinct carinae, with moderately strong central longitudinal impression covered with transversal striae. Hind femur 4.8× as long as wide; posterior spur of hind tibia 0.75×as long as hind metatarsus. Hind claw with two or three strong teeth. Areolet pointed, vein 2m-cu strongly distad its middle; vein 1cu-a postfurcal by 2× its width; postnervulus intercepted in the middle. Metasoma slender, but apical tergites not distinctly compressed. 2 nd tergite 2.0× longer than wide; 3 rd tergite about as long as wide. Thyridium roundish, its distance to basal margin of 2 nd tergite 2.0× its length. Apical margin of 7 th tergite straight, not excised medially. Ovipositor unmodified. Color: black. Palps ivory. Mandible except teeth yellowish. Tegula black. 1st and 2nd tergites entirely and 3 rd tergite medially black; 3 rd tergite laterally and following tergites entirely reddish-brown. Coxae black; trochanters and trochantelli black, ± yellowish apically. Fore femur red, blackish ventrally; fore tibia and tarsus red. Mid femur black, narrowly yellow apically; mid tibia yellowish, sub-basally and apically black; mid tarsus cream-yellow. Hind femur black; hind tibia black, with ivory spot basally; hind tarsus black, metatarsus with narrow ivory ring basally. Wings hyaline, pterostigma dark brown. ♁ unknown. Taxonomical remark: This new species runs to Casinaria nigrotrochanterata RIEDEL in the key of Western Palaearctic Casinaria species (RIEDEL 2018), but differs by larger ocelli, reduced carination of propodeum, black tegula, reddish-brown apical tergites and mainly blackish hind tibia.
