Description.

Holotype, female, length of body 8.3 mm (of fore wing 7.6 mm).

Head. Antenna with 22 segments; frons spaced punctate and vertex densely punctate with no smooth interspaces (Fig. 319), with rather long setae; temple rugulose-punctate (Fig. 322); head gradually narrowed behind eyes, eye in dorsal view 1.3 times as long as temple (Fig. 319); occipital carina narrow medio-dorsally; supra-antennal elevations medium-sized (about 0.2 times as long as scapus), outer side oblique and largely smooth except for sparse punctures; clypeus slightly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.4 times its height (Fig. 324); mesopleuron obliquely rugose; notauli narrow, deep and finely crenulate; middle lobe of mesoscutum coarsely irregularly rugose, lateral lobes longitudinally rugose (Fig. 323); scutellar sulcus complete, moderately wide and crenulate; scutellum densely and coarsely reticulate-rugose, convex anteriorly and near level of mesoscutum, but flattened medially; metanotum medially slightly convex, not protruding and densely reticulate-rugose (Fig. 323); propodeum coarsely reticulate-rugose (Fig. 323); posterior propodeal carina thick lamelliform.

Wings. Fore wing: length of vein 1-M 1.3 times as long as vein 1-SR (Fig. 321).

Metasoma. First tergite 0.4 times as long as apically wide, smooth and with shallow elliptical depression medially (Fig. 325); other tergites and all sternites densely and finely punctate (Figs 325, 327); second sternite distinctly convex medially, rather flattened anteriorly and posteriorly; third sternite about 0.1 times as long as second sternite (Fig. 327).

Colour . Black; head anteriorly with moderate orange-brown pattern (Fig. 318); remainder of head black except for yellowish brown outer orbita (Fig. 322); mesosoma laterally black except for ventral and dorsal brown small patches of pronotal side and middle mesoscutal lobe strongly contrasting with both lateral lobes, yellow laterally and orange-brown medially (Fig. 323); scutellum largely orange-brown, only medio-posteriorly and narrowly black laterally (Fig. 323); axilla with small brown patch; metasoma dorsally black, first three tergites with posterior orange-brown stripes, other tergites with large orange-brown patch medially; metasoma ventrally black (Fig. 323), first sternite with orange posterior brown stripes black basally, second and third sternites with pair of small orange-brown patches latero-posteriorly; palpi and antenna (but ventrally brown) dark brown; patch on middle and hind coxae, all trochanters partly, apex of all femora, fore and middle tibia tarsi dark brown, remainder of legs black; pterostigma and anterior half of fore wing largely dark brown (Fig. 321), remainder of wing membrane hyaline.

Male . Unknown.

Biology.

Unknown. Collected in June.

Distribution.

Etymology.

From “cordatus” (Latin for “heart-shaped”) after the cordate shape of the yellow and orange-brown middle lobe of the mesoscutum.
