Mesosoma. Mesosoma 1.6 × as long as high. Collar of pronotum long (Fig. 5 D – F View Figure 5 ). Pronotum strigose on coriaceous surface laterally (Fig. 5 D, E View Figure 5 ). Mesoscutum strongly convex (Fig. 5 E View Figure 5 ), with notaulus reaching middle of mesoscutum (Fig. 5 F View Figure 5 ); surface of mesoscutum granulate with scattered punctures except longitudinally strigose postero-median portion (Fig. 5 F View Figure 5 ). Epicnemial carina complete (Fig. 5 E View Figure 5 ); subtegular ridge sharp (Fig. 5 E View Figure 5 ); impression below speculum weak (Fig. 5 E View Figure 5 ); sternaulus distinct, crenulate, sharp, almost reaching base of mid coxa (Fig. 5 E View Figure 5 ); posterior transverse carina of mesosternum absent; surface of mesopleuron obliquely strigose, smooth anteriorly, speculum slightly polished (Fig. 5 E View Figure 5 ). Scutellum highly elevated above metanotum (Fig. 5 E View Figure 5 ), with crenulate lateral carina reaching apex and dorsal surface almost flat (Fig. 5 F View Figure 5 ); hind margin of metanotum with a triangular projection on each side of metanotum (Figs 5 F View Figure 5 , 6 A View Figure 6 ). Juxtacoxal carina distinct, complete (Fig. 5 E View Figure 5 ). Propodeum in profile with triangular area basalis flat and evenly slanted from base of area superomedia (Fig. 5 E View Figure 5 ); regular carinae of propodeum complete (Fig. 6 A View Figure 6 ); area superomedia hexagonal, 1.4 × as long as wide (Fig. 6 A View Figure 6 ); apex of area dentipara with very strongly developed, long and sharp apophysis, almost perpendicular to surface of propodeum, apophysis almost straight (Fig. 6 A View Figure 6 ); surface of propodeum smooth (Fig. 6 A View Figure 6 ); area petiolaris indistinct laterally, transversely strigose (Fig. 6 A View Figure 6 ). Propodeal spiracle 1.4 × as long as wide.
Legs. Legs very slender and long (Fig. 5 A View Figure 5 ); all legs longer than fore wing. Hind femur and tibia 4.5, 7.0 × as long as maximum width respectively; ratio of length of tibiae fore: mid: hind = 1.0: 1.1: 1.6.
Wings. Fore wing 5.9 mm long; areolet 1.5 × as wide as long, 1.5 × as high as 3 rs-m, 0.9 × as high as 2 m-cu, pentagonal and sides nearly parallel, slightly narrowing anteriorly (Fig. 6 E View Figure 6 ); 1 cu-a opposite M & RS (Fig. 6 E View Figure 6 ); ramulus absent (Fig. 6 E View Figure 6 ). Hind wing with cu-a one-fourth as long as first abscissa of CU.
Metasoma. Metasoma mostly coriaceous (Fig. 6 B – D View Figure 6 ). First tergite in profile almost straight, slightly bent downward at base of postpetiole (Fig. 6 B View Figure 6 ), smooth anteriorly, irregularly sculptured between latero-median carinae; in dorsal view 5.0 × as long as wide at base (Fig. 6 C View Figure 6 ); petiole very long, rounded in cross-section, of approximately equal width and height (Fig. 6 B, C View Figure 6 ); in dorsal view petiole slightly broadened posteriorly; latero-median carina present only on anterior portion of postpetiole (Fig. 6 C View Figure 6 ). Second tergite in dorsal view 2.6 × as long as wide anteriorly, distinctly punctate (Fig. 6 D View Figure 6 ). Gastrocoelus slightly impressed, in form of longitudinal groove (Fig. 6 D View Figure 6 ). Thyridium oval, distant from base of second tergite by 0.3 × its length (Fig. 6 D View Figure 6 ). Tergites 3–6 smooth with laterotergites separated by distinct creases (Fig. 6 B View Figure 6 ). Sternites 2–5 laterally sclerotized and middle part not sclerotized (Fig. 6 B View Figure 6 ). Hypopygium with apical margin rounded and longitudinally folded in middle. Ovipositor sheath with apex pointed, protruding beyond apex of metasoma (Fig. 6 B View Figure 6 ).
Colour. Body black except following: clypeus apically, maxillary and labial palps, face antero-laterally, scape and pedicel, flagellomeres 7–11, frons laterally, pronotum antero-laterally, mesopleuron anteriorly, scutellum posterior half, propodeum, metapleuron, fore and mid legs except tarsi, hind coxa, femur, tibia proximal half, basitarsus distal half, tarsomeres 2–4, first metasomal tergite posterior 1 / 3, second metasomal tergite posterior half, metasomal tergites 6–7, ovipositor yellow.
Male. Similar to female except: body length 5.1 mm, white inner orbits and clypeus laterally, apically; dorsal inner orbit patch narrowly separated from wider white line below antennal sockets. T 1 and hind coxa (rest of hind legs missing) largely dark brown. Gonostyle narrow, ‘ finger-like’.
Distribution.
Oriental region ( India).
Etymology.
We dedicate the new species to the National Geographic Society (NGS) for their outstanding support for the Siang Expedition in which specimens of the new species were collected. It’s a humble dedication to the society in recognition of their committed support to explore, illuminate and protect the wonders of our world through research. The epithet natgeo is treated as a noun in apposition.
Comparative diagnosis.
The new species is distinctive and unique as the fore wing areolet is very large, hardly narrowing anteriorly. The propodeal spiracle is also shorter than in other Heinrichiellus , 1.4 × as long as wide. Superficially this species resembles Heinrichiellus brevispinus sp. nov. but can additionally be separated by the length of the propodeal apophyses and the shape of the area superomedia.
