Diagnosis.

Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, anteroventral contour of mesopleuron convex ( Fig. 165A, I ), propleuron with fine punctations throughout ( Fig. 165A, I ), longitudinal median carina on face present ( Fig. 165B ), surface of metasternum convex, edges of median area on T2 obscured by weak longitudinal stripes ( Fig. 165G, H ), dorsal outer depression on hind coxa absent ( Fig. 165A, J ), and fore wing with r vein slightly curved, outer side of junction of r and 2RS veins forming a stub ( Fig. 165K ).

Coloration

( Fig. 165 A–L ). General body coloration polished black except pedicel yellow-brown; scape and all antennal flagellomeres brown on both sides; labrum and mandibles yellow-brown; glossa maxillary and labial palps, and tegulae yellow; clypeus, dorsal furrow of pronotum, dorsal ATS groove, lunules, BS, PFM, BM, and lateral ends of metanotum with a slightly brown-red/reddish tints. Eyes and ocelli silver. Fore and middle legs yellow except brown claws, and middle coxae proximally with a brown spot; hind legs yellow except black coxae, distal 1/3 of femora brown, additionally with a narrow dorsal brown strip from top to bottom; tibia brown with 1/3 distal yellow, and tarsomeres brown, although basitarsus proximally with a yellow band. Petiole on T1 black and sublateral areas yellow; T2 with median and adjacent areas brown, silhouette of adjacent area well-defined, and lateral ends yellow; T3 mostly brown, proximally dark area coincides with the width of median and adjacent area onT2, and proximal half of lateral ends yellow; T4 and beyond completely brown; distally each tergum with a narrow yellow translucent band. In lateral view, T1-3 completely yellow; T4 yellow, but dorsally brown; T5 and beyond brown. S1-3 yellow; S4 yellow, but medially brown; penultimate sternum and hypopygium brown.

Description.

Head ( Fig. 165 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.06, 0.25:0.06, 0.23:0.06), distal antennal flagellomere longer than penultimate (0.13:0.06, 0.10:0.06), antenna longer than body (3.03, 2.78); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, punctate-lacunose, interspaces wavy and longitudinal median carina present. Frons smooth. Temple wide, punctate-lacunose and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.11, 0.13). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 165A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces wavy/lacunose. Scutellum long and slender, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune with complete and undulate/reticulate carinae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation with a sloped transverse strip and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM oval/circular with a short proximal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick and smooth; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum with medium-sized punctation and with a median longitudinal dent, but no trace of median longitudinal carina, proximal half weakly curved; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by faintly concave/wavy carina; nucha surrounded by very short radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.07). Hind coxa with medium-size punctate throughout, dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.21, 0.15), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.15, 0.12).

Wings ( Fig. 165K, L ). Fore wing with r vein straight; 2RS vein straight; r and 2RS veins forming an angle at their junction and outer side of junction forming a slight stub; 2M vein slightly curved/swollen; distally fore wing [where spectral veins are] with microtrichiae more densely concentrated than the rest of the wing; anal cell 1/3 proximally lacking microtrichiae; subbasal cell with microtrichiae virtually throughout; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 165A, G, H, J ). Metasoma laterally compressed. Petiole on T1 with sculpture on distal half, virtually parallel-sided over most of length, but barely narrowing over distal 1/3, apex truncate (length 0.32, maximum width 0.18, minimum width 0.13), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.19, length T2 0.19), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.19, maximum width 0.25, minimum width 0.12); T2 scarce pubescence throughout. T3 longer than T2 (0.24, 0.19) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.

Cocoon. Unknown.

Comments.

Male.

Similar in coloration to female, although the metasoma is slender and cylindrical .

Etymology.
