Diagnosis. This subspecies can be distinguished from others by the presence of a triangular yellow maculation on the supraclypeal area of females, forewing orange-yellow subhyaline, metasomal terga I and II black setae, terga III–VI covered by yellow-orange setae, metatibia and metabasitarsus with black setae except yellowish-orange setae on posterior margin of metatibia.

Description. Female: Total body length (holotype) 14.5 mm, forewing length (holotype) 11.5 mm. Head broader than long, approximately 1.5× as broad as long ( Fig. 14A View Fig ). Mandible bidentate. Labrum with tubercles baso-laterally, rather broadly emarginate medio-apically ( Fig. 14B View Fig ). Clypeus convex in profile, about 1.6× as broad as long and slightly depressed medioapically ( Figs. 13A View Fig , 14A View Fig ). Scape slender, about 4.4× as long as broad, flagellomere I slender, about 5× as long as broad, flagellomere II shortest, as broad as long, flagellomeres III–IV subequal in lengths and longer than flagellomere II, flagellomeres VI–IX subequal in lengths and longer than flagellomere III, flagellomere X long, about 2.3× flagellomere II in length ( Fig. 14C View Fig ). Mesosoma round, approximately as broad as long ( Fig. 14D View Fig ). Forewing with three submarginal cells, first and third submarginal cells broader than second submarginal cell, 1m-cu entering at two-third length of second submarginal cell ( Fig. 14E View Fig ). Pygidial plate with lateral margins gradually converging to rounded apex ( Fig. 14F View Fig ).

Clypeus with dense, wrinkled punctures laterally and medio-apically, punctures round and separated by 0.5–1.5× puncture width, sparser punctures medially, forming a impunctate linear longitudinal area on midline basally, and minute area medioapically. Supraclypeal area with faint, sparse punctures except denser punctures laterally ( Fig. 14A View Fig ). Labrum with dense punctures of unequal size, punctures contiguous but small and sparse basally and laterally, punctures separated by 1–1.5× puncture width. Mandible with elongate, wrinkled punctures on basal half and impunctate on remainder ( Fig. 14B View Fig ). Paraocular area, frons, and vertex with elongate, dense punctures. Mesoscutum and mesoscutellum with rather round, dense, contiguous punctures, size of punctures unequal. Metasomal terga with small, round, dense punctures, space between punctures about 0.5–1× puncture width.

Body black except labrum with dark ferruginous marks baso-laterally; mandible with dark reddish brown on basal half; supraclypeal area with triangular yellow mark ( Fig. 14A View Fig ); scape dark brown except ferruginous basally and apically, flagellomere I dark brown except ferruginous apically, flagellomere II dark ferruginous, flagellomeres III–X pale ferruginous ventrally ( Fig. 14C View Fig ); forewing orange-yellow hyaline ( Fig. 14E View Fig ). Most of legs dark ferruginous except lighter on apical tarsomeres, pretarsal claws apically. Sterna dark ferruginous.

Setae on body plumose except for simple setae mostly found on clypeus and labrum. Clypeus with some extremely short, yellow setae except dense, longer, yellowish grey plumose setae laterally. Labrum with short, yellow setae. Paraocular area with short, dense, yellowish grey setae. Frons, inner space betweenocelli with dense, blackish setal tufts ( Fig. 14A View Fig ). Vertex and occiput with dense, blackish setae ( Fig. 14D View Fig ). Mesoscutum blackish setae except yellowish grey setae basally and yellowish grey setae laterally. Mesoscutellum with dense, blackish setae ( Fig. 14D View Fig ). Propodeum with yellowish grey setae. Anterior-facing surface and base of dorsal-facing surface of tergum I with long, sparse yellowish grey setae, remainder of tergum I with long, dense, black setae; tergum II dense, black setae except orange-yellow setae apically; terga III–VI with dense, yellow-orange setae ( Fig. 13B View Fig ); sterna I–IV with long, grey setal bands apically. Sternum V with long, orange grey setae apically. Ventral surface of pro- and mesofemora with long, blackish setae; anterior, posterior margins, and apex of protibia with yellowish setae, inner surface of protibia and probasitarsus with stiff, dense ferruginous setae; outer surface of mesotibia and mesobasitarsus with blackish setae except yellowish setal tuft on mesotibia apically; inner surface of mesotibia with sparse, blackish setae. Outer surface of metafemur with dense, black setae except ferruginous setal tuft apically. Outer surface of metatibia with long, dense, stiff, black setae except yellowish-orange setae on posterior margin, inner surface of metatibia with blackish setae. Outer surface of metabasitarsus with stiff, dense, black setae; inner surface with ferruginous setae ( Fig. 13A View Fig ).

Etymology. The subspecific epithet refers to the country of Vietnam and is combined with the Latin suffix – ‘ica’– feminine form of ‘-icus’ meaning, “belonging to” or “derived from”.
