Figs 69, 70, 117, 141, 151, 168, 194, 234  
 Description. Holotype FEMALE. Fore wing 14.8 mm.   
 Head. Ventral tooth of mandible longer than dorsal tooth. Clypeus apical area delimited by smooth or creased border; clypeal margin with one small tooth. Antenna beyond flagellomere XII missing; white band starting at flagellomere V; 5 flagellomeres at least 50% white.   
 Mesosoma. Covered with very fine pilosity, seen mostly with tangent light (Fig. 141), otherwise apparently glabrous; hairs longest and most distinct behind propodeal apophyses. Mesopleuron weakly but distinctly and entirely strigate. Subalar prominence very narrow, almost linear, punctuate (Fig. 151). Sulcus between sternaulus and scrobe weak. Posterior transverse carina of mesosternum entirely absent (Fig. 168). Lower metapleuron weakly strigate-rugulose, ventrally with dense, delicate white pilosity. Propodeum (Fig. 70): area in front of anterior transverse carina entirely alutaceous to very finely rugulose, matt, medially with two complete, straight, diverging longitudinal ridges. Propodeal apophyses stout, scale-like. Posterior transverse carina clearly developed in between apophyses, approximately horseshoe shaped. Area between anterior transverse carina and petiolar foramen transversely strongly strigate-rugose. Fore wing in Fig. 194; vein 3-Cu 1.68 length of 4-Cu. Hind wing in Fig. 234.   
 Metasoma. Postpetiole dorso-anteriorly with very small, linear depression; dorsolateral carina weakly indicated above and behind spiracle, not reaching apex of tergite; median dorsal carina absent; petiolar spiracles in dorsal view not prominent. Ovipositor 1.38 length of hind tibia. Apex of lower valve with 15 teeth.   
 Color. Mesosoma dark red; head and metasoma main color black, with pale yellow stripes. Lateral pattern as in Fig. 69. Orbital band well delimited, widely interrupted at malar space, briefly interrupted at 12 h; width on supraclypeal and supra-antennal areas and gena ventrally about 0.15 of interocular distance, on gena, narrowing progressively towards dorsal part. Labrum pale yellow. Clypeus, including apical area, malar space dorsally, and parantennal impression, black; supraclypeal area dark red; pale yellow spot on each side between parantennal impression and base or torulus; supra-antennal area centrally transversely dark red, otherwise black; mandibles entirely black. Mesosoma unicolorous, devoid of yellow marks (Figs 69, 70), except pronotum anterior margin medially with two pale yellow spots. Fore and mid coxae and femora and hind coxa with same color as pleural region, hind coxa ventro-apically with large blackish spot; fore and mid trochanters and trochantelli with blackish marks; hind trochanter, trochantellus and coxa black; fore tibia dorsally dark brown, ventrally pale yellow; mid tibia black, except basal end ventrally with tiny whitish mark; hind tibia black, basal 0.1 whitish; fore tarsus dark brown, except t1 dorsally pale yellow; mid t1 basal 0.2 and apical 0.1 black, centrally whitish, t2–5 black; hind t1 basal 0.2 black, t1 otherwise and entire t2–3 white, t4–5 black. Metasoma black, T1 and T3 apical margin with narrow pale yellow stripe, somewhat diffuse on T1; T2 medially on apical margin with thin, straight, transverse pale yellow line; T4–7 apical stripe widely interrupted, absent dorsally; T8 black.   
 Morphological variation. Although known from a single specimen, some color variation for the extension of black on the hind femur might be expected, since it is highly variable for all species of the inflatus group; it seems however to be of no taxonomic relevance in defining species.   
MALE. Unknown.  
 Comments. The following combination of features is characteristic for this species: clypeal sulcus indistinct, clypeus continuous with supraclypeal area; anterior area of propodeum covered with fine sculpturing, matt; posterior transverse carina of mesosternum absent; mandible entirely black, without basal yellow spot; mesosoma, except appendices, entirely dark red.   
 Material examined. HOLOTYPE ♀ [Db13] “Abitagua, Ecuador // Rio pastazer 1000m // XI.4.39// W.Clarke.McIntyre ”; “near// Mesostenus // rufithorax // CWT’58 Tasch.”; “ Digonocryptus // sp.27// Tow.1966”. Right wings slide mounted, left antenna entirely and right antenna beyond flagellomere 12 missing, metasomal segments 6–8 broken but attached to specimen; otherwise in good shape. Distribution. Ecuador.
