In his description of Indodynerus malickyi, Gusenleitner (2010) mentioned that the clypeus is slightly longer than wide, but judging

from his fig.4, it is slightly wider than long. Below we provide a redescription of the species for future study.

Description. — Female. Body length about 11 mm; forewing length about 10.5 mm. Head in frontal view subcircular, about 1.15 times as wide as high. Vertex with cephalic foveae small, bearing dense pubescence, situated far from each other with distance between foveae about equal to distance between posterior ocelli; depression for cephalic foveae obsolete. Distance from posterior ocelli to apical margin of the vertex about twice of the distance from posterior ocelli to inner eye margin ( Fig. 1 ). Gena narrower than eye, in lateral view about 0.7 times as wide as eye; occipital carina complete, present along entire length of the gena. Inner eye margins weakly convergent ventrally; in frontal view about 1.2 times further apart from each other at vertex than at clypeus. Clypeus in lateral view weakly and smoothly convex; in frontal view about 1.1 times as wide as high, with basal margin slightly convex medially ( Fig. 2 ) and distinctly separated from antennal sockets; apical margin shallowly emarginate medially, forming a blunt tooth on each lateral side ( Fig. 2 ); width of the emargination less than 1/3 width of clypeus between inner eye margins. Mandible quadridentate, basal tooth with inner margin much reduced to a straight line, second and third teeth short with inner margins slightly produced to form round edges, outer one pointed apically with inner margin nearly straight ( Fig. 3 ). Antennal scape about 3.5 times as long as its maximum width; flagellomere I about 1.3 times longer than wide, flagellomere II about as long as wide, flagellomeres III–IX wider than long, terminal flagellomere bullet-shaped, as long as its basal width ( Fig. 4 ).

Pronotal carina slightly raised, slightly produced at humeral angles, reaching ventral corner of pronotum. Mesoscutum weakly convex, about as long as wide between tegulae; anterior margin broadly rounded. Scutellum weakly convex, strongly depressed along anterior margin with many short longitudinal carinae. Metanotum weakly convex, sloping down to apical margin. Propodeum excavated in the middle, the basal fovea about 1/3 of the length of the median carina which runs from the fovea to the apical margin; in lateral view outline of the posterior surface slightly curved; border between posterior and lateral surfaces rounded.

First metasomal segment narrower than second, truncate at base; anterior vertical surface convex, with some shallow punctures, clearly separable from the posterior horizontal part, but without carina; tergum divided laterally by a sharp carina into upper and lower parts. Tergum I in dorsal view less than twice as wide as long; tergum II slightly wider than long; sternum II nearly flat at base, then slightly convex to apical margin ( Fig. 5 ).

Body covered with short, ferruginous hairs except lower part of propodeum with dense long silver hairs.

Clypeus with dense, large, flat-bottomed punctures, each bearing a golden bristle, punctures at the center larger than at sides. Mandible with several shallow small punctures. Frons densely covered with coarse punctures. Vertex and gena with punctures similar to those on frons. Pronotum with punctures coarser than punctures on vertex and gena, spaces between punctures very narrow, slightly raised to form reticulation. Mesocutum densely and coarsely covered with flat-bottomed punctures, punctures on scutellum and metanotum dense, coarse and equal to those on mesoscutum. Mesepisternum with dense, coarse, well-defined punctures in posterodorsal part, barely punctured in anteroventral part; border between posterodorsal and anteroventral parts distinct. Dorsal metapleuron with striae, ventral metapleuron with sparse shallow punctures. Propodeum with punctures dorsally and laterally similar to those on mesopleuron, posterior surface with shallow sparse large punctures. Metasomal segments densely covered with strong punctures, punctures on tergum II coarser than on terga III–V, tergum and sternum IV with minute punctures.

Colour. Black; following parts orange-yellow: large spots on upper lateral corner of clypeus, narrow band along inner eye margin extending from bottom of frons nearly to ocular sinus, a spot on frons, spots on basal mandible, antennal scape beneath, narrow band at apical margin of first and second terga. Legs black. Wings dark-brown, strongly infuscate, veins dark brown.
