Diagnosis

Vein r of fore wing extremely short ( Fig. 6E ), vein 3-SR about 12 × as long as vein r; vein 1-CU1 of fore wing short ( Fig. 6E ); vein 1-M of fore wing yellowish; apical tooth of mandible comparatively slender ( Fig. 6J ); eye small and in lateral view 0.9 × as wide as temple ( Fig. 6C ); clypeus with three minute teeth ( Fig. 6D ); fore wing with brown patches ( Fig. 6A ); hind basitarsus white and strongly contrasting to dark brown hind tibia; vein 2-CU1 curved basally in holotype, but straight in paratype.

Etymology

Named after the protruding antennal sockets, from the Latin ‘ corona ’ for ‘crown’.

MEASUREMENTS. Length of body 5.2 mm, of fore wing 4.8 mm.

COLOURATION. Head yellow but frons, vertex medially and stemmaticum dark brown; mesosoma yellow except lower lateral angle of prosternum, mesoscutum excluding notauli and scutellar sulcus dark brown, most of mesopleuron, metapleuron and mesosternum brown; metasoma brown; vein 1-M of wing yellow with veins 3-SR, 2-SR, 2-M, cu-a, 2-CU1 and 1-SR+M brown; legs yellow but coxa basally, middle and hind femur, and hind tibia brown.

HEAD. Width 1.3× median length in anterior view ( Fig. 6D ) and part of head above eye in lateral view 0.3× height of eye ( Fig. 6C ); antennae missing; OOL: diameter of posterior ocellus: POL=41: 10: 6; eye 1.1 × temple in dorsal view ( Fig. 6B ); frons with longitudinal rugae medially, rugose laterally and with weak median ridge; vertex granulate-rugose and with satin sheen; temple largely striate and with satin sheen; face obliquely rugose and with short median crest; clypeus mostly smooth, shiny and about as long as minimum width of face, intertentorial distance 2.9× minimum width between clypeus and eye, clypeus long erect setose and with 3 small and distinctly spaced teeth medio-ventrally ( Fig. 6D ); eye small and in lateral view 0.9× as wide as temple ( Fig. 5B ), in anterior view its height 0.6 × minimum width of face; upper condyle of mandible far below lower level of eyes ( Fig. 6D ); malar space 0.8× as long as basal width of mandible; lower tooth of mandible very small, 0.2 × length of apical tooth ( Fig. 6K ).

MESOSOMA ( Fig. 6F ). Length 1.5× its width in lateral view; side of pronotum mainly rugose, but dorsally nearly smooth; mesoscutum densely rugose and rather shiny, densely setose; notauli hardly indicated; scutellar sulcus wide and with six carinae ( Fig. 6F ); scutellum triangular, flat, distinctly longitudinallygranulate and rather shiny; metanotum with short median carina anteriorly and small tooth protruding posteriorly; propodeum coarsely reticulate-rugose, latero-posteriorly distinctly tuberculate, no median or transverse carinae.

WINGS. Fore wing 2.8× as long as its maximum width; length of 1-R1 1.4× as long as pterostigma; r issued rather far beyond middle of pterostigma and 0.2 × 3-SR; distance between 1-R1 and wing apex 0.4 × 1-R1; 2-SR nearly straight and converging to posterior margin of pterostigma ( Fig. 6E ); SR1 slightly bent; 2-SR+M present; parastigma small; 1-CU1 almost absent; r: 3-SR: SR1 =2: 13: 33; 2-SR: 3-SR: r-m=25: 13: 8; 2-M straight apically and curved basally ( Fig. 6E ).

LEGS ( Fig. 6I ). Hind femur moderately wide and with satin sheen, 3.7× as long as wide and rather widened submedially; hind tibia rather swollen; middle tibia with medium-sized pale-yellow blister; hind coxa smooth and shiny.

METASOMA ( Fig. 6G–H ). Carapace oval in dorsal view, 1.7× as long as wide and 1.1× as long as mesosoma; first and second tergites coarsely and densely longitudinally rugose; second suture wide; third tergite 1.7× as long as second tergite and laterally weakly curved, in lateral view slightly convex posteriorly, in dorsal view convex medially, densely and semi-circularly rugose and rounded ( Fig. 6G ), lateral lamella narrow, medio-apically widely emarginate; ovipositor sheath narrow and parallel-sided ( Fig. 6H ), with some long and erect setae; hypopygium apically acute, lacking an up-curved triangle or apical spine ( Fig. 6H ).

VARIATION. Vein 2-CU1 curved basally in holotype but straight in paratype; third tergite 1.5–1.7× as long as second tergite.
