Mesosoma ( Fig. 112). Pronotum lateral portion next to mesopleuron inconspicuously corrugated, epomia inconspicuous; notaulus faintly impressed, inconspicuously, minutely corrugated, especially anteriorly, not reaching middle of mesoscutum; mesopleuron dorsal half medially inconspicuously rugulose, especially dorsally, ventral half without distinct ridges or rugae, epicnemial carina restricted to ventral 0.7 of mesopleuron, posteriorly inconspicuously, sparsely corrugated; mesopleural groove moderately corrugated; sternaulus anterior half faintly corrugated; postpectal carina medially straight ( Fig. 46); metapleuron, subapical fovea shallow, subcircular; pleural carina moderately stout, or inconspicuous; propodeum anterior area short, PLL 0.61 ( Fig. 50), anterior transverse carina distinct, complete, medially distinctly arched forwards, posterior area moderately strigate-rugose, with ridges medially slightly arched backwards, spiracle very elongate, SWL 2.67, propodeal apophyses long, thornshaped, AHD 2.36. Legs ( Fig. 70): Hind t4 posterior lobe about 0.35 × as long as anterior lobe. Fore wing vein (Rs+M)b nearly straight, limit with crossvein 1m-cu distinct, ramellus absent; vein Rs&1M uniformly slightly curved; crossvein 1cu-a uniformly slightly convex, arising opposite or slightly apicad vein Rs&1M, angle with vein M+Cu about 90 degrees; vein 2Cua much shorter than crossvein 2cu-a, FWC 0.44; areolet small, APH 0.92; vein 2Ma approximately as long as vein 2Mb; vein 2Mb tubular; crossvein 2m-cu with bulla short, about 0.2 × as long as vein length or shorter; vein 2Rsb sinuous. Hind wing vein 2-1A long, reaching about 0.8 × the distance to wing margin, HWC 1.50.

Metasoma ( Fig. 112). T1 petiole basal half smooth towards base, apical half, postpetiole coriarious-punctulate, except pospetiole apical parts centrally smooth, sparsely punctulate, spiracle at about basal 0.7, prominent, T1LW 2.58, T1WW 2.75, T1GL 0.33; T2 moderately short, apically robust, T2T1L 0.78, thyridium distinctly longer than wide, T2LW 0.94, T2WW 1.96. Ovipositor approximately straight, OST 0.51, dorsal valve with nodus absent, notch absent; ventral valve tip with inconspicuous serrations restricted to very tip.

Color. Head black, mesosoma and legs orangish brown (125, 092, 057), metasoma mostly dark brown (073, 054, 042) and dark yellowish (189, 164, 034). Head: Scape ventrally whitish (218, 216, 195) towards apex; scape and pedicel dorsally, flagellomeres 1, 5–9 entirely white; clypeus dark brown; mouth parts whitish, except mandible apex blackish. Mesosoma: Ventrally blackish; collar dorsally, tegula laterally and propodeal apophyses white; propleuron darker than pronotum, except ventro-lateral corner white; mesoscutum medially with centroposterior square dark mark; scutellum centrally darkish; propodeum anterior portion darkest. Legs: Fore and mid coxae and trochanters, hind coxa apical margin, hind trochanter basal margin, dorsal longitudinal line and ventrally, and hind tibia basal 0.2 white; trochantellus ventrally, femora basal 0.1 and hind tibia ventrally lightest; trochantellus apical parts dorsally, fore and mid femur ventrally, fore and mid tibiae anteriorly and posteriorly, rather mid tibia dorsal elliptical mark at apex, pale yellow (241, 224, 144) to whitish. Fore wing with two distinct dark spots, on apical half of cell 3M and 1+2R1, and cell 1Cu apical parts, and respective surrounding areas. Metasoma: T1 and T2 entirely, and T3 basal half dark brown, except T1 basal margin and apical 0.2, and T2 apical 0.3 with white stripe, T2 stripe interrupted at central 0.3–0.6; T3 apical half, T4–8 basally brown, dark yellowish toward tergites apex; T6 apical margin, T7 and T8 dorsally, and sternites medially white; ovipositor sheath dark brown, except basal 0.7 ventrally whitish; ovipositor light brown (187, 144, 084).

Male. Unknown.

Variability. Color: Propodeum anterior area darkish marks sometimes restricted to anterior portion, or even taking posterior area apically; extension and brightness of lightest marks on legs variable; extension of yellowish marks on T3–8 variable, from blackish toward tergites base to entirely yellowish.

Comments. Included in the D. typurum species group (see item Species Delimitation). Among all Debilos spp. , D. sanimum along with D. okarum , D. masipum , and D. makirum uniquely have the mesoscutum with a medial, centro-posterior square dark mark. Within this set of species, however, D. sanimum is most likely to be mistaken for D. masipum , because of their very similar body color pattern, especially the metasoma posterior half dark yellowish. Debilos sanimum differs from D. masipum by having the collar dorsally white (vs. entirely white), postpectal carina medially straight (vs. distinctly bent), propodeum anterior area short, PLL 0.61 (vs. very long, PLL 1.23), propodeal spiracle very elongate, SWL 2.67 (vs. distinctly elliptic, SWL 1.80), and hind tarsus without white marks (vs. t2 entirely and t3 basal half whitish).

Debilos tasamunum also has the metasoma posterior half dark yellowish, but D. sanimum can be differentiated from it by having the flagellomere 1 dorsally white (vs. without white mark), collar dorsally white (vs. entirely white), mesoscutum medially with centro-posterior square dark mark (vs. without medial dark mark), propodeum anterior area short, PLL 0.61 (vs. very long, PLL 1.33), propodeal spiracle very elongate, SWL 2.67 (vs. distinctly elliptic, SWL 1.80), and hind tarsus without white marks (vs. t1 apically, t2 and t3 white).

Etymology. From the Carib word sanìme, meaning “short, small,” in reference to the propodeum anterior area distinctly short in this species.

Distribution. Brazil. Apparently associated to Atlantic rainforest, recorded from only one locality at Espírito Santo: Reserva Biológica Duas Bocas, Cariacica (20°16’21”S 40°28’40”W) ( Fig. 150).
