Diagnosis. Length of fore wing 4.25–4.56 mm; pronotal fovea obsolete, humerus short and roundly truncate, carina with lamella reduced ( Fig. 24 ); mesoscutum with sparse and notably elongated setae; metanotal process distinctly wider than long, with apex rounded; propodeum with a wide and deeper cavity ( Fig. 25 ); deeper and numerous mesopunctation on mesoscutum; color brownish with marks yellow ( Fig. 26 ), mesoscutum brownish, scutellum with two marks, metanotum with yellow band anterior; preapical region of aedeagus not angular ( Fig. 43 ).

Description. FEMALE. Length of fore wing 4.25 mm; clypeus wide (HClp=0.55; MxWClp=0.80; TeW=0.50; MiWClp= 0.77 mm), with ventral margin acute; tentorial pit closer to antennal socket than to eye margin; interantennal area relatively wide, approximately 2 × diameter of antennal socket; mandibles relatively short with length 0.78 × distance between eyes at vertex; occipital carina distinct, strong and salient throughout; humerus short and roundly truncate, carina with lamella reduced ( Fig. 24 ), pronotal fovea obsolete, preceded by a short and low prominence; length of mesoscutum approximately 0.87 × its width; mesepisternal groove absent; scutellum with a short but well-marked median line; metanotum triangular, length of median axis approximately 0.86 × width of central disk, metanotal process distinctly wider than long, with apex rounded; propodeum with a wide and deeper cavity ( Fig. 25 ); T1 sessile with distal margin wider and nearly straight, cup-like.

Mesoscutum with sparser micropunctation and deeper and numerous mesopunctation; mesopleuron and T2 to T5 with distinct punctures; clypeus with short golden bristles, except on ventral margin, which has elongated bristles; vertex, mesoscutum, scutellum and metanotum with sparse and notably elongated setae ( Fig. 24, 26 and 56 ).

Species ferruginous with few yellow spots ( Fig. 26 ); antennae ventrally testaceous, dorsally brown; mandibles yellow, with apex brown, clypeus and frons entirely testaceous to yellow, inner orbit with wide band that extend to ocular sinus, two marks inconspicuous on vertex, small mark on pronotal carina and fovea, mesoscutum brownish, tegulae yellow, large spot on mesepisternum, metapleuron without spot, scutellum with two spots, metanotum partially, propodeum with paired dorsal marks, distal spot on T1 to T3. Legs testaceous to ferruginous; wings hyaline, venation brown.

MALE. Length of fore wing 4.45 mm; eyes wide, produced inwards; clypeus with ventral margin acute; tento- rial pit closer to eye margin than to the antennal socket; gena narrow; color like female. Male genitalia. Parameral spine narrow, without elongate bristles; basal and apical angle of paramere widened ( Fig. 41 ); digitus wide, with apical margin approximately rounded; basal process of digitus narrow and acuminate; digitus and cuspis filled with dense and elongated bristles ( Fig. 44 ); ventral process of aedeagus approximately lobed, strongly sclerotized and not serrated ( Fig. 42 and 43 ); preapical region of aedeagus not angular ( Fig. 43 ).
