Digonocryptus yacamus Aguiar et Ramos , sp. nov.

Figs 29, 30, 215, 255

Description. Holotype FEMALE. Fore wing 16.1 mm.

Head. Ventral tooth of mandible approximately as long as dorsal tooth. Clypeus apical area delimited by sharp border or carina; clypeal margin with two very weak teeth. Antenna with 28 flagellomeres; white band starting at flagellomere V; 4 flagellomeres at least 50% white.

Mesosoma . Mesopleuron with scarce short hairs, about 99% of cuticular surface visible; mostly smooth. Subalar prominence more or less elongate, weakly keeled. Sulcus between sternaulus and scrobe absent. Posterior transverse carina of mesosternum absent. Lower metapleuron densely striate-rugulose. Propodeum: area in front of anterior transverse carina polished, smooth, medially without ridges from carina towards anterior margin. Propodeal apophyses conspicuous, higher than wide, somewhat compressed (oblong in cross-section). Posterior transverse carina weakly and incompletely developed between apophyses, triangular. Area between transverse carinae regularly obliquely striate-rugose; area behind posterior transverse carina striate-rugose mostly transversely. Fore wing in Fig. 215; vein 3-Cu 1.35 length of 4-Cu. Hind wing in Fig. 255.

Metasoma. Postpetiole dorso-anteriorly, at level of spiracles, weakly but distinctly concave; dorsolateral and median dorsal carinae absent; petiolar spiracles in dorsal view somewhat prominent, protruding from T1. Ovipositor 1.38 length of hind tibia. Apex of lower valve with 16 teeth.

Color. Black, with orange coxae and whitish marks. Lateral pattern as in Fig. 29. Orbital band interrupted only between 4–7 h; width on supraclypeal and supra-antennal area about 0.2 of interocular distance, on temple and gena half as wide, linear. Labrum and clypeus yellowish. Head otherwise dark brown. Mesosoma dorsally dark brown, except as follows. Pronotum with traces of yellow dorso-anteriorly (from marginal stripe), dorso-lateral margin with almost linear yellow stripe. Scutellum antero-lateral angles with large yellow spot, one on each side. Propodeum as in Figs 29–30, apex of apophyses with yellowish spot. Wing membrane distinctly and uniformly amber, darker on tip. All coxae orange brown, fore coxa darker basally. All femora and hind tibia dark brown. Fore tibia mesal side and longitudinal stripe on lateral side white, otherwise dark brown. Mid tibia, except base and apex, dorsally and partially on each side whitish, otherwise dark brown. Fore tarsus dark brown, except t1 mesally mostly whitish. Mid t1 basal 0.2 and apical end, and entire t2–5 dark brown, t1 central 0.7 whitish. Hind t1 basal 0.5, apex of t4, and entire t5, dark brown, t1 apical half, entire t2–3 and most of t4 white. Metasoma dorsally dark brown, except as follows. Postpetiole apical margin with two small whitish spots, one on each side. Apical whitish stripes widely interrupted medially, except on T7 complete and narrow.

Morphological variation. Fore wing 13.7–16.1 mm. Ovipositor 1.37–1.41 length of hind tibia. Clypeal margin teeth varying from indistinct to clearly differentiated. Posterior transverse carina of propodeum sometimes weakly developed, from triangular to horseshoe-shaped. Clypeus often brownish or dark brown. Pronotum dorso-anterior margin and collar rarely (10%) with distinct yellow stripe; dorso-lateral margin sometimes only with small yellow spot. Scutellum yellow spots rarely small. Propodeal apophyses rarely (10%) without yellowish spot at apex. T7 apical margin dorsally sometimes without yellow stripe. T7 latero-dorsal small yellow dot usually (60%) present.

MALE. Unknown.

Comments. Similar to D. cennitus from which it can be separated readily by having mid and hind coxae orange brown (vs. black); orbital band almost complete (vs. restricted to very narrow stripe between 10–11 h and 1– 2 h). Also similar to D. banius from which it can be easily differentiated by having T2–6 apical margin with whitish stripes (vs. without); and fore wing without dark spot (vs. with a fuscous transverse spot).
