Temelucha latastigma nov.sp.

Female. Front wing 3.1 mm, body 4.8 mm, ovipositor sheath 2.2 mm long. Head not narrowed behind, temple swollen ( Fig. 1 ). Occipital carina widely obsolescent above. Ocellus diameter 0.75 as long as distance between lateral ocellus and eye. Frons weakly concave above antennal sockets, mat. Antenna slightly shorter (2.8 mm long) than front wing ( Fig. 3 ), weakly thickened apically. Flagellum with 24 segments. First segment 3.8 as long as wide, penultimate segment almost square. Inner eye orbit slightly divergent downwards ( Fig. 2 ). Face 2.2 as high as wide, rare punctured on shine surface. Clypeus rather flat with almost right apical ridge and few long setae. Malar space 0.7 as long as basal width of mandible.

Epomia, notaulus and sternaulus faint. Scutellum not carinated laterally. Prepectal carina reaching subtegular swelling. Mesosoma coarse but rare punctured. Mesopleuron with longitudinal concavity (transversally striated) below speculum. Fore wing with very wide pterostigma. Second radius curved to front margin of wing. Second recurrent vein (2mcu) postfurcal, with single bulla. Nervulus interstitial, parallel vein connected postnervulus above its middle. Hind wing with 5 distal hamuli and not intercepted nervellus, discoidella absent ( Fig. 3 ). Legs moderately slender, hind femur 4.0 as long as wide. Longer spur of hind tibia slightly shorter (8:9) than apical width of tibia. Correlation between hind tarsal segments as 27:14:9:6:9. Tarsal claws pectinated basally. Propodeum fully areolated. Areola hexagonal, pointed in front ( Fig. 4 ).

First metasomal segment 1.4 as long as second tergum. Ventral margins of first segment not touching each other. First, second and basal half of third tergum longitudinal striated.

Ovipositor sheath as long as front wing from base to apex of radial cell ( Fig. 5 ). Ovipositor thick with weakly curved down tip and faint subapical dorsal notch.

Black; antenna from bellow, inner and outer eye orbit widely, clypeus, malar space, mandible, palpi, large triangle spot on hind upper area of pronotum, lateral and median longitudinal stripes on mesonotum, scutellum entirely, subtegular swelling, front and middle legs, apical half of hind coxa, hind trochanters except lower basal half of hind one, hind tarsus, apical spot on first and second terga, apical half of III-VII terga and II- VII sternites yellow; pterostigma and hind femur yellow orange, hind tibia yellow on middle, unclearly darkened sub basally and apically.

Male unknown. In Sedivy’s key the species runs to T. signata HOLMGREN , but it is differs by not touching ventral carinae of first metasomal segment, entirely yellow inner and outer eye orbit, more short area superomedia, more wide pterostigma, slightly divergent down inner eye orbit, first metasomal segment longer than second tergum, longer ovipositor sheath, smaller size and coloration of the body.

Holotype female, Bulgaria, Plovdiv, 160 m, 29.09.1999, in collection of Plovdiv University.

Etymology: The species name is derivate from Latin "lata" (= wide) associated with very wide pterostigma in front wing.
