Diagnosis.

Body length 5.5-5.8 mm, forewing 5.4-5.5 mm (Fig. 86 View Figures 86–94 ); interspaces between punctures leathery; black, with the following parts whitish yellow: whole clypeus in male, antenna ventrally in male, two anterior spots of pronotum dorsally (or not), outer margin of tegula, apical bands of both T1-T2 and S2, apical spot of S3 laterally (or not), part of tibiae; mandibular teeth ferruginous in male. Body with sparse and small punctures; in front view, head slightly subquadrate, two lateral margin almost parallel (Fig. 87 View Figures 86–94 ), in dorsal view head thick, vertex prolonged (Fig. 88 View Figures 86–94 ); mandible enlarged and angular, the outer edge curved (Fig. 87 View Figures 86–94 ); clypeus punctate, interspaces between big punctures densely micropunctate, and sparser at apex, clypeus wider than long (1.3 × in female), apically with deep U-styled emargination wider than depth (1.5 × in female) (Fig. 87 View Figures 86–94 ); interantennal carina at the same level as frons; in female A6-A12 thick and short, A13 in male wide and flat, backward reaching apical margin of A9; frons wide and swollen, with a medial longitudinal furrow from anterior-ocellus to base of interantennal carina; frons, vertex and gena with sparse and deep punctures, interspaces with extremely minute punctures (Fig. 88 View Figures 86–94 ); occipital carina curved latero-ventrally (Fig. 91 View Figures 86–94 ). Mesosoma with sparse and deep punctures, interspaces with extremely minute punctures (Fig. 90 View Figures 86–94 ); sharp angle of pronotal carina at humeral angle, and pronotal carina posteriorly with a row of short longitudinal carinae; mesoscutum with two longitudinal furrows of punctures on posterior margin; anterior margin of scutellum with a row of dense punctures, and with a shallow longitudinal furrow in the middle; metanotum medially with transverse raised bulge (Fig. 90 View Figures 86–94 ); propodeal furrow deep, propodeal carina in the furrow developed and complete (Fig. 89 View Figures 86–94 ). Metasoma leathery, punctures smaller and shallower than those on head and mesosoma, punctures on T1 a little larger and deeper than the second metasomal segment, and those on metasomal segments 3-6 indistinct (Figs 7-9 View Figures 1–9 ); in dorsal view, the first metasomal segment bell-shaped, the second one with narrow apical lamellae; S2 concave basally, and flat in lateral view (Fig. 94 View Figures 86–94 ).
