Diagnosis.
Pedicel bilobed, long and thick (Figs 4D-E View Figure 4 ; vs. calciform and elongate in Cretolyra noijebumensis gen. et sp. nov.); axillae almost rounded and reduced on edges of mesoscutellum, not contiguous medially (vs. contiguous medially in Cretolyra noijebumensis gen. et sp. nov.); axillar grooves smooth (Fig. 4A View Figure 4 ; vs. axillar grooves crenulated in Cretolyra noijebumensis gen. et sp. nov.); medial cell nearly triangular, with 1m-cu very short (Fig. 2B View Figure 2 ; vs. medial cell rectangular, with 1m-cu distinct in Cretolyra noijebumensis gen. et sp. nov.).
Description.
Body length 2.82 mm. - Head globular, higher than long (length ca. 0.40 mm), covered with short setae; frons convex, smooth, divided by sulcus; compound eye oval, higher than long; vertex convex; clypeus smooth, apically rounded; mandibles symmetrical, with three teeth; toruli separated from each other by less than their own diameter; subantennal groove present; antenna about half body length; scape shorter than pedicel; pedicel thick, bilobed; flagellomeres cylindrical, longer than wide; flagellomere 1 shorter than flagellomeres 2-5 (length 0.15 mm vs. ca. 0.21 mm); flagellomeres 6-11 shorter (length ca. 0.10 mm); flagellomere 12 as long as flagellomere 1 (length 0.15 mm); occipital carina minutely crenulate. - Mesosoma one third of body length (length 0.98 mm); mesoscutum convex, divided by smooth median mesoscutal sulcus; parapsidal lines present; axillae small, almost rounded and not contiguous medially; axillar groove smooth; mesoscutellum smooth, convex, diamond-shaped; pronotum smooth, not visible dorsally, with posteromedial part moderately high as viewed laterally; anterior thoracic spiracle not surrounded by pronotal cuticle posteriorly; mesometapectal sulcus crenulate; propodeum carinate. - Fore wing hyaline and covered with microtrichiae, two thirds of body length (length 2.57 mm); pterostigma reduced; C, Sc+R, M+Cu, A, Rs fully pigmented; R1 extending beyond marginal cell; Rs closing marginal cell in straight line; M pigmented to apex; medial cell small, elongate and rectangular, nearly triangular by side of 1m-cu. - Legs with two mesotibial and one metatibial spurs; metacoxa elongate; metafemur and metatibia swollen; metabasitarsus two to three times as long as remaining metatarsomeres; row of comb-like setae along ventral surface of metatibia and metabasitarsus. - Metasoma longer than mesosoma (length 1.44 mm); elongate and narrowed at apex; tergites smooth; hypopygium well-developed; ovipositor shorter than metasoma (length 1.33 mm; OL/BL ratio 0.43), sheaths fully preserved, transversely striated.
