Diagnosis.

Petiole on T1with a mix of fine rugae and coarse sculpture over most of the surface ( Fig. 47H ), precoxal groove shallow, but visible ( Fig. 47A, I ), fore wing with vein 1 cu-a curved, r vein curved, outer side of junction of r and 2RS veins not forming a stub ( Fig. 47K ), dorsal outer depression on hind coxa present ( Fig. 47A ), inner margin of eyes diverging slightly at antennal sockets ( Fig. 47B ), propodeum without median longitudinal carina ( Fig. 47G ), and lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Fig. 47H ).

Coloration

( Fig. 47 A–L ). General body coloration polished black except scape, pedicel, all antennal flagellomeres (on both sides) and tegulae brown; glossa, maxillary and labial palps light yellow-brown; labrum, mandibles, dorsal furrow of pronotum, lunules and BS brown-red/reddish. Eyes gray and ocelli reddish (in preserved specimen). Fore and middle legs light yellow-brown, except brown/brown-reddish coxae, additionally femora, tibiae and tarsomeres with a narrow dorsal brown strip from top to bottom, and claws brown; hind legs light yellow-brown except black coxae, femora with a small brown area on the apex, tibia and tarsomeres brown, additionally femora, tibiae, and tarsomeres with a narrow dorsal brown strip from top to bottom. Petiole on T1 black and sublateral areas yellow-brown; T2 with median area black and lateral ends brown; T3 and beyond completely brown; distally each tergum with a narrow yellowish translucent band. In lateral view, T1-2 completely yellow-brown; T3 yellow-brown, but dorsally brown; T4 and beyond completely brown. S1-3 completely yellow-brown; S4 and beyond completely brown.

Description.

Head ( Fig. 47 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.25:0.10, 0.25:0.10, 0.25:0.10), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.12:0.06), antenna longer than body (3.78, 2.88); antennal scrobes-frons sloped and forming a shelf. Distal half of face dented, laterally with punctations barely noticeable, interspaces smooth 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 subequal in length with OOL (0.11, 0.12). Malar suture faint. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 47A, F, G, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, and interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct 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 short stubs delineating the area; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM circular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick and smooth with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum without median longitudinal carina, proximal half curved with rather coarse sculpture and distal half with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and short stubs; propodeal spiracle distally framed by a short transverse carina; nucha surrounded by long 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 finely sculptured only ventrally 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 entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.08). Dorsally hind coxa with scattered punctation, medially smooth and ventrally with dense punctation, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.31, 0.20), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.14, 0.14).

Wings ( Fig. 47K, L ). Fore wing with r vein slightly curved; 2RS vein slightly concave; r and 2RS veins forming a weak, even curve at their junction and outer side of junction not forming a stub; 2M vein straight; 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; vein 2 cu-a absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a curved, 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. 47 H–J ). Metasoma cylindrical . Petiole on T1 with a mix of fine rugae and coarse sculpture over most of the surface, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.34, maximum width 0.17, minimum width 0.14), and with scattered pubescence on distal half. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.17, length T2 0.17), edges of median area polished and followed by a deep groove, median area broader than long (length 0.17, maximum width 0.20, minimum width 0.10); T2 with pubescence only distally. T3 longer than T2 (0.23, 0.17) and with scattered pubescence only distally.

Cocoon ( Fig. 47E ). White or beige oval cocoon with silk fibers messy/disordered/fluffy.

Comments.

The distal half of petiole with contours convex. The distal half of propodeum with a transverse discontinuous carinae present only laterally, proximally with a dent in each lateral side, proximal half with coarse sculpture. The limit between mesopleuron and metasternum with a flattened area. The middle part of petiole is elevated, at different level that the remaining portion of the structure.

Female.

Unknown.

Etymology.
