Digonocryptus caceres Aguiar et Ramos , sp. nov.

Figs 37, 38, 109, 110, 121, 163, 164, 182, 222

Description. Holotype FEMALE. Fore wing 11.0 mm.

Head. Ventral tooth of mandible approximately equal in length to dorsal tooth. Clypeus apical area delimited by somewhat round, bulbous elevation, with brief emargination centrally ( Fig. 121); clypeal margin with two distinct small teeth. Antenna with 26 flagellomeres; white band starting at flagellomere V; 7 flagellomeres at least 50% white.

Mesosoma . Mesopleuron with scarce tiny hairs, 100% of cuticular surface visible, centrally with weak, longitudinal, transverse strigate, otherwise smooth. Subalar prominence large and round, suboval, not keeled. Sulcus between sternaulus and scrobe absent. Posterior transverse carina of mesosternum absent. Lower metapleuron faintly transversely strigate, with fine pilosity slightly more evident than on mesopleuron. Propodeum pilose, hairs much longer than on metapleuron; area in front of anterior transverse carina polished, smooth or with faint sculpturing, medially with traces of two medio-longitudinal ridges. Propodeal apophyses present as small scale-like structures. Posterior transverse carina present but weak and inconspicuous. Area between transverse carinae from transversely to concentrically and regularly strigate, continuing on area behind posterior carina, except radially around petiolar foramen. Fore wing in Fig. 182; vein 3-Cu 1.42 length of 4-Cu. Hind wing in Fig. 222.

Metasoma. Postpetiole medio-apically very weakly convex, nearly flat; dorsolateral and median dorsal carinae absent; petiolar spiracles in dorsal view not prominent; T8 basal depression and longitudinal crease weak. Ovipositor 1.44 length of hind tibia. Apex of lower valve with 13 teeth.

Color. Head and dorsal mesosoma main color black, body otherwise predominantly light orange (255,165,087). Lateral pattern as in Fig. 37 (paratype from Bolivia). Orbital band pale yellow, complete, except interrupted at malar space, covering entire supra-clypeal area; width on supra-antennal area about 0.2 of interocular distance, on temple about 0.15, then widening suddenly to cover gena entirely; behind ocelli forming short projection towards center ( Fig. 110). Clypeus yellow, except apical area dark brown. Pronotum dorsally along anterior margin with wide yellow stripe from side to side, laterally along dorsal margin with elongate yellow spot. Propleuron antero-mesal 0.3 dark brown, laterally and apically yellow. Mesoscutum centrally, between notaulus, at level of tegula, with large yellow spot. Subalar prominence, tegula and scutellum yellow. Axillar carina yellow, except dorsal margin. Postscutellum pale yellow. Propodeum as in Figs 37–38 (paratype from Bolivia). Coxae , trochanters and femora light orange, all tibia yellowish; in all cases, lighter on fore leg, darker on hind leg; fore and mid tarsomeres 1–2 colored as respective tibia, apical tarsomeres dark brown; hind tarsus entirely yellow, brighter than on respective tibia. Metasoma unicolorous, light orange .

Morphological variation. [Fore wing of identical length for both females]. Ovipositor 1.29–1.44 length of hind tibia. On female specimen from Bolivia orbital band interrupted between 1–2 h ( Fig. 109), and posterior transverse carina of propodeum absent.

MALE. Very similar to female on all features, except as follows. Specimen from Cáceres ( Brazil) with 27 flagellomeres, white band with 8 articles, starting at apical 0.5 of flagellomere IX; fore t1–4 light colored as respective tibia. Specimen from Tucuman ( Argentina) with 32 flagellomeres; white band with 10 articles, starting at flagellomere VII; orbital band interrupted between 2–3 h. Variability: in the specimen from Cáceres the apical flagellomeres are compactly united ( Fig. 163), while in the male from Tucuman they are clearly spaced ( Fig. 164).

Comments. Similar to D. siraeus from which it can be distinguished by having two clypeal teeth (vs. one); clypeal suture fully yellow (vs. entirely and distinctly black); pronotum with longitudinal yellow stripe at dorsal margin (vs. without yellow marks); yellow around eyes covering entire genal width on basal half (vs. as a narrow stripe at gena); postscutellum yellow (vs. black). Also similar to D. petrus , from which it can be distinguished by having speculum, carinal triangle, and a small area near prepectal carina dark orange as remaining of mesopleuron (vs. yellowish); propodeum without yellow (vs. medio-longitudinally with a faint to distinct, elongate, wide yellow mark); T1 with no traces of yellow (vs. with small, faint to distinct yellow dot dorso-apically).

Material examined. 2 females, 2 males. HOLOTYPE ♀ “Cáceres, MT.// 13.XI.1984 // Buzzi, Mielke, Elias// Casagrande leg.// PROJ. POLONOROESTE// G-4”; “ Digonocryptus // sp.// A. F. Yamamoto det. 1985// C.I.I.F.” ( DZUP). Mesoscutum somewhat damaged by pin, hind basitarsomeres compressed, probably by pins holding specimen during drying process; otherwise in good shape .
