Description.

(Female)Head (Figs 4-5) 1.60 × wider than long, covered with long erect setae and short decumbent white setae; frons transversely rugose; surface around ocellar triangle smooth with rows of punctures behind anterior ocellus and outside of posterior ocelli; vertex reticulate-rugose; eye margined posteriorly by foveate groove and single post-ocular orbital carina; gena smooth with irregular carina under orbital carina; occipital carina not forming a depression; clypeus punctuate with small punctures.

Mesosoma (Fig. 6) entirely covered with short decumbent setae, but long erect setae also present on mesonotum; mesoscutum smooth except lateral carina present on anterior surface; dorsal mesoscutal surface not humped; axilla and scutellum smooth; metanotum setose; propodeum (Figs. 13) with pair of median, submedian and lateral carinae; median region narrowed anteriorly, with eight indistinct transverse carinae, posterior margin posteriorly produced; submedian propodeal region converging posteriorly, with two transverse carinae excluding posterior areola; lateral region with two (right side) or four (left side) transverse carinae.

Fore wing (Fig. 4) bearing four transverse dark bands but separation between second and third bands indistinct; vein M 2.2 × basal part of RS; erect setae on C 1.2 × longer than those on Sc+R, equal to those on vein A.

Metasoma smooth except anterior surface of 6-8th metasomal tergites shagreened; ovipositor 1.29 × mesosoma length, apex with small teeth and single knob.

Color. Body entirely black except tarsi and ovipositor sheath dark brown, ovipositor reddish brown; long setae on vertex, gena, mesonotum and dorsal surface of hind tibia and basitarsus black, other setae white.

Measurements. Head 0.80 mm long, 1.55 mm wide; mesosoma 2.15 mm long; scutum 1.35 mm wide; propodeal disc 0.75 mm long, 1.10 mm wide; fore wing 4.85 mm long; metasoma 1.90 mm long, 1.20 mm wide; ovipositor 2.75 mm long; total body length excluding ovipositor 4.85 mm.

(Male) Unknown.

Distribution.

Sulawesi Island.

Etymology.

This species is named for its black legs.

Remarks.

This species is similar to Ettchellsia reidi Mita & Shaw, sp. n. by the almost flat mesoscutum, however, it is distinguished from the latter by the anteriorly weakly narrowed median region of propodeum (Fig. 13) and the mostly smooth surface between posterior ocellus and eye (Fig. 5).
