Elasmus curticornis Gunawardene & Taylor 2012

Body length. 1.48–2.13 mm. Coloration. Head and mesosoma blackish with green sheen, except antenna, mandibles and base of tegula cream, dorsellum translucent. Gaster primarily orange, except T1 black, T4 with or without posterolateral dark spots meeting medially, posterior part of T5 to end of gaster black or T5 with transverse dark stripe and T6 to end of gaster dark, S6 to end of gaster black. Leg 1 with base of coxa black, remainder yellow except basal infuscation on femur; legs 2 and 3 each with coxae black except distal ends yellow, trochanters yellow, femora mostly brown except proximal and distal ends yellow, tibiae and tarsi yellow. Head. Slightly narrower than mesosoma; in dorsal view 2.0 times wider than long; in frontal view slightly (1.1 times) wider than high. Vertex and frons with dense piliferous punctures, with interspaces on frons subequal to diameter of punctures. Ocellar triangle about twice as long as wide, POL:OOL 2.3–2.5:1, OD:OOL 0.3–0.4:1, OC:OD 0.8–0.9:1. Compound eye 1.5–2.1 times as high as wide in lateral view; inner margins of compound eyes straight to slightly concave, frons minimum width 0.7 times total head width. Malar space 0.4–0.5 times eye height; lower margin of toruli 2.1–2.5 times their diameter from lower margin of face, about in line with lower margin of eyes. Each mandible with seven teeth. Antenna (Figure 4B, C). Scape 0.5 times as long as pedicel and flagellum combined, lengths of scape and of pedicel and flagellum combined 0.6–0.7 times and 1.0–1.2 times compound eye height; pedicel 1.4–1.8 times as long as wide, 1.3 times length of funicle 1; funicle 1 subtriangular, 0.9–1.0 times as long as wide; funicle 2 and 3 each shorter than (0.8 times and 0.8–0.9 times length of, respectively) funicle 1, funicle 2 0.6–0.7 times and funicle 3 0.6 times as long as wide; clava 1.4–1.5 times as long as wide, 2.3–2.8 times as long as and 1.3 times as wide as funicle 3, clava 3 triangular. Mesosoma (Fig. 4D, E). 1.5–1.7 times longer than wide. Mesoscutum 0.9 times as long as wide, densely covered with piliferous punctures; posterior margin of mesoscutum concave. Scutellum 0.9 times as long as wide, finely reticulate, setae absent except elongate setae at anterolateral and posterolateral corners, anterior and posterior pairs of setae of similar length, posterior setae not extending beyond apex of dorsellum. Dorsellum length 0.7 times basal width. Wings. Hyaline. Forewing (Fig. 4F, G) 1.4–1.5 times length of head and mesosoma combined, 3.3–3.6 times as long as wide; isolated subcubital line of setae present; postmarginal vein subequal in length to stigmal vein. Hind wing 0.9 times length of forewing, 5.1 times as long as wide. Legs. Mid femur with stout apical posterolateral seta 0.2–0.3 times length of tibia. Hind tibia with dorsal pattern of black setae demarking four diamonds anterolaterally and three diamonds posterolaterally. Gaster. Gaster 0.8–1.1 times length of head and thorax combined, 2.1–2.3 times as long as wide, not produced; posterior margin of T6 straight.
