Hecabalodes anthaxiae Wilkinson, 1929 Figures 6A-E , 7A-E

Hecabalodes anthaxiae Wilkinson, 1929: 106, ♀♂.

Re-description of female.

Body length: 4.2 mm; ovipositor length: 2.35 mm; fore wing length: 2.5 mm. (we re-describe this species in full because of the short original description of Wilkinson (1929)): Dark brown, except for the yellowish hue on lateral sides of T1 and T2 as well as apex of T2 (Figs 6A, B , 7E ); antenna orange, scape slightly darker (Fig. 6C ); legs dark brown (except for the yellowish base of fore tibia, and all tarsi), telotarsi darker. Fore wing subhyaline, with distinct infuscation along marginal cell (Fig. 7D ).

Head (Figs 6C-E , 7A ): 1.3 × as wide as its median length, slightly wider than mesoscutum; coarsely rugose; head behind eye broadly rounded; temple 0.6 × as long as eye height in dorsal view; POL 1.6 × OD, 0.9 × OOL; eye with few scattered short setae; malar space 0.4 × as long as eye height, 1.2 × as long as basal width of mandible, malar suture absent; face smooth laterally just behind eyes; face 1.5 × as wide as eye width, 0.8 × as long its length combined with clypeus; hypoclypeal depression more or less quadrate, ca. as wide as its distance from eye; occipital carina complete dorsally, not meeting hypostomal carina ventrally; antenna broken; scape twice as long as its maximum width; F1 6.5 × as long as its apical width, 1.2 × as long as F2; ocellar triangle with base longer than lateral sides. Mesosoma (Fig. 7A-C ): 2.3 × as long as its height; pronotum with two sharp transverse carinae dorsally; mesoscutum gently rounded above or at the same level of pronotum when seen from lateral view, flattened on disc, densely rugose, finely alutaceous laterally; notauli indistinct; mesoscutellum slightly convex, truncate at apex, finely sculptured, with a number of thick carinae laterally; mtn 0.4 × as long as mesoscutum, with a short longitudinal median carina and 2-3 oblique submedian carinae on its depressed anterior part, convex postero-medially; propodeum finely and sparsely granulate, with two short postero-medial, parallel carinae, 0.3 × as long as propodeal length, median longitudinal carina of propodeum absent; mesopleuron finely punctate, with irregular spaces in between, shiny; precoxal sulcus shallow, irregular, running ventrally along almost the entire length of mesopleuron. Fore wing (Fig. 7D ): 3.6 × as long as its maximum width; pterostigma 1.7 × as long as maximum width; vein M + CU1 slightly curved; 1-SR+M nearly straight; vein r-m absent; vein r arising at basal third of pterostigma; 2-SR 1.75 × as long as r, slightly longer than m-cu, 0.6 × as long as 1-SR+M; 1CU1 0.2 × as long as 2CU1. Hind wing (Fig. 7D ): With fringe of long, fine setae along apical and anal margins; vein 1-M 1.7 × as long as 1-rm. Legs. Hind coxa (Fig. 7C ) 1.7 × as long as wide, without distinct basoventral tubercle, finely punctate especially ventrally, with some fine whitish setae distally and laterally; hind femur 2.6 × as long as wide; hind tarsus 1.1 × as long as hind tibia; hind basitarsus slightly shorter than rest of tarsomeres combined; second tarsomere 0.55 × as long as hind basitarsus, 2.2 × as long as telotarsus (excluding arolium); outer edge of hind tibia with long, fine whitish setae. Metasoma (Figs 6A, B , 7E ): 1.3 × as long as head and mesosoma combined; T1 and basal half of T2 with distinct interrupted longitudinal striae, somewhat dotted in between; T1 1.5 × as long as its apical width; T2 0.9 × as long as its apical width, 2.7 × as long as T3; posterior half of T2 finely reticulate, T3-5 (except posterior margin of T5 smooth and shiny), finely reticulate; T6 entirely smooth and shiny. Ovipositor sheath about as long as or slightly longer than metasoma (Fig. 6A, B ), and the fore wing as well.

Material examined.

Kingdom of Saudi Arabia, 1♀, Jazan, Farasan Islands, Al-Sajid; 16°51'25.46"N, 41°55'58.78"E; 10 Nov.2017; Abu El-Ghiet & El-Sheikh leg.; LT [KSMA].
