(Figs 1B; 2C)  
 Xyalaspis hyalina Belizin, 1951: 574 (male).   
 TYPE MATERIAL.— Holotype. ♂ with the following labels: “Kondara, 20.IX, Tadzhik SSR, 1945, V. Gussakovskij ” (white label, handwritten, in Cyrillic); “ Holotypus Xyalaspis hyalinus ♂, V. Belizin det” (red label, handwritten), “ Xyalaspis hyalinus, V. Belizin, Kovalev det 1996” (white label). (Deposited in ZIN).   
OTHER MATERIAL EXAMINED. — Cyprus: Pera Pedri Krios R, 10.IX.1937, G. A. Mavromoustakis, B. M. 1987-808, 1♂ (NHM).  
BIOLOGY. — Unknown.  
DISTRIBUTION. — Palaearctic. Known from Russia, Kazakhstan, Tajikistan (Belizin 1951), Armenia (Belizin 1961), first record from Cyprus.  
 DIAGNOSIS. — Species close to X. laevigata, but it can be distinguished by the presence of incomplete notauli, scutellar spine slightly projected upwards in lateral view and antennae longer than the body (notauli weakly impressed in X. laevigata but complete, scutellar spine straight in lateral view and antennae shorter than the body).   
REDESCRIPTION (MALE ONLY)  
 Length   
Body 2.8 mm. Wings 2.6 mm. Antennae 3.2 mm.  
 Coloration   
Head, mesosoma and metasoma black. Mandibles yellowishbrown with darker teeth. Antennae yellowish-brown. Legs yellowish-brown with darker coxae. Wing venation yellow.  
 Head   
Width of head 1.2 × its height in front view and 1.8 its length in dorsal view. Face smooth, shiny and pubescent, with abundant piliferous punctures. Malar sulcus present, coriaceous, 0.5 × height of compound eye. Transfacial line subequal to height of compound eye. Diameter of toruli equal to inter-toruli distance and larger than torulus to compound eye distance. Clypeus not apparent; smooth, glabrous and convex. Occipital and postocular carinae absents. Compound eyes completely glabrous. POL:OOL:LOL ratio = 6:4:2.5, ocelli diameter 2. Frons smooth, shiny and shortly pubescent with some punctae.  
 Antennae   
Flagellomeres cylindrical and hairy. Antennal formula: 25(11), 9.5(9.5), 25(8), 25.5(8.5), 26(8.5), 24.5(8.5), 26(8), 26(8), 25(8), 25(7.5), 25(7), 23(7), 23(7), 28(6). Placodeal sensilla start at F1.  
 Mesosoma   
Pronotum carinated in its lower part and smooth on its upper side (Fig. 2C). Mesoscutum 1.2 × wider than long in dorsal view. Mesoscutum smooth, pubescent and punctate, with alutaceous sculpture at base of notauli. Notauli weakly impressed and lacking internal carinae, being replaced by weak carinated sculpture at anterior third of the mesoscutum (Fig. 1B); median mesoscutal furrow weakly impressed. Parapsidal signum and parascutal sulcus absent. Scutellum 0.8 as long as mesoscutum in dorsal view. Scutellar foveae smooth, basally defined by a carina and including an oblique internal carina. Interfoveal line complete. Lateral pits of scutellar foveae distinct. Scutellar spine narrowing apically; slightly projected upwards in lateral view.Mesopleuron smooth, shiny and glabrous, basally carinated. Mesopleural triangle smooth and pubescent. Propodeum heavily areolate and pubescent; central area divided by a longitudinal median carina and a several transverse carinae defining eight cells.  
 Wings   
Pubescent. Radial cell of the forewing closed, 2.4 × longer than wide. Marginal pubescence of forewing denser in its apical third.  
 Metasoma   
Petiole as long as wide, dorsally smooth and laterally and ventrally carinated. T3 3.6 × longer than T 4 in dorsal view. T5 and T6 are visible in dorsal view. Metasoma smooth and glabrous.
