Type material.

Holotype: Saudi Arabia • ♀; Asir, Abha, Hay Al-Nusub; 18°13'N, 42°30'E; 2226 m alt.; 24.vii.2013; H.A. Dawah leg.; ZDAMU Reg. No. HYM.CH.873, body, dissected head with one antenna and one dissected hind leg on card; one pair of fore wing and antenna on slide under two coverslips, slide HYM.06.

Diagnosis.

The new species is similar to L. insularis in having a yellow band on the pronotum and scutellum and distinct discal, preapical, and marginal carinae, but the new species differs from L. insularis as follows: discal carina on pronotum strong and angulate (discal carina on pronotum weak and straight in L. insularis ); metafemora oval with eight ventral teeth, basal tooth triangular and robust (metafemora slender with nine ventral teeth, basal tooth angular and pointed in L. insularis ); pubescence on sides of propodeum and metatibia relatively short and less dense (pubescence on sides of propodeum and metatibia long and more dense in L. insularis ) ovipositor hardly reaching posterior margin of GT4 (ovipositor distinctly reaching beyond posterior margin of GT1 in L. insularis ).

Description.

Colour (Figs 2A , 3 ). Head dark brown; maxillary and labial palps yellowish brown; antenna dark brown except scape with posterior margin yellow. Mesosoma dark brown except a yellow transverse strip in front of discal carina, not continuing to sides of pronotum, and a narrow, transverse yellow strip on scutellum just above apex. Gaster largely reddish to dark brown, with transverse yellow strips medially on GT4 and apically on GT5. Basal two-thirds of ovipositor reddish brown; the rest dark brown. Pro- and mesofemur brown, with yellow tips where joining tibia; pro- and mesotibia reddish brown, with their margins yellow; hind legs dark brown except apex of coxa in ventral view and margins of femur yellow; all tarsi yellow. Fore wing below PMV and in apical half strongly infuscate, the rest hyaline.

Head (Fig. 2A ). Head in frontal view 1.2 × as broad as high and as wide as posterior margin of pronotum; less densely punctuate, medially at psa smooth, setae on face and eyes silvery, erect, and less dense; POL 2 × OOL and 3 × MOD; scrobe 1.5 × as wide as parascrobal area, transversely carinate; occipital carina distinctly visible between and beyond posterior ocelli; malar space 0.35 × eye height and as long as F7; flagellum with erect, black setae; F1 widened apically, as long as broad and shortest of all funicular segments individually; F3-F5 subequal in length; F7 longest; clava 1.7 × as long as broad, distinctly longer than F7 and F8 combined (Fig. 2B ); mandible tridentate.

Mesosoma (Fig. 3A, C ). Mesosoma densely punctuate, punctures setigerous, with dense, long, pale setae; setae denser on propodeal callus; discal, preapical, and marginal carinae well developed, raised, and angulate; posterior margin of scutellum with punctures in a line with margins and with carina; propodeum medially with a complete carina. Hind leg with coxa punctuate, carinate and subserrate posterodorsally; metafemur oval, 1.9 × as long as broad, punctuate, and setose, with eight ventral teeth; basal tooth robust, 3-5 longer than rest and subequal (Fig. 3B ); metatibia with spine subequal to spur. Fore wing 3.2 × as long as broad, with dense, black setation towards apical margin; STV with bifurcate uncus; uncus longer than apical process of stigmal vein (Fig. 2C ). Hind wing 4.4 × as long as broad (Fig. 2C ).

Metasoma (Fig. 3A, C ). Gaster moderately punctuate, with dense, pale setae; density of setae more at epipygium. GT1 wider than long, interiorly with triangular process attached to petiole and, medially with a raised carina, narrower than GT4 in dorsal view; GT4 with posterior margin entire; ovipositor sheaths long, nearly reaching anterior margin of GT3.
