Mesosoma ( Fig. 102). Epomia faint; notaulus faintly impressed, uniformly sculptured with mesoscutum, not reaching middle of mesoscutum ( Fig. 42); mesopleuron dorsal half medially inconspicuously rugulose, especially dorsally, ventral half without distinct ridges or rugae, epicnemial carina restricted to ventral 0.8 of mesopleuron, posteriorly inconspicuously, sparsely corrugated; mesopleural groove faintly, sparsely corrugated; sternaulus anterior 0.6 faintly corrugated; postpectal carina medially straight to slightly arched posteriorly; metapleuron, subapical fovea shallow, subcircular; pleural carina moderately stout; propodeum anterior area short, PLL 0.68, anterior transverse carina distinct, complete, medially distinctly arched forwards, posterior area faintly strigaterugose, with faint ridges medially slightly arched backwards ( Fig. 9), spiracle distinctly elliptic, SWL 2.00 ( Fig. 56), propodeal apophyses long, thorn-shaped, AHD 3.33. Legs ( Fig. 67): Hind t4 posterior lobe about 0.38 × as long as anterior lobe. Wings ( Fig. 33): Fore wing vein (Rs+M)b nearly straight or slightly sinuous, 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 moderately shorter than crossvein 2cu-a, FWC 0.54; areolet small, APH 0.71; vein 2Ma distinctly longer than vein 2Mb; vein 2Mb tubular ( Fig. 34); 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 1.82.

Metasoma ( Fig. 102). T1 petiole basal half smooth towards base, apical half, postpetiole imbricate, except pospetiole apical parts smooth, spiracle at about basal 0.7, not prominent, T1LW 2.90, T1WW 2.73, T1GL 0.27; T2 moderately short, apically robust, T2T1L 0.78, thyridium distinctly longer than wide ( Fig. 18), T2LW 0.99, T2WW 2.10. Ovipositor approximately straight, OST 0.51, dorsal valve with nodus absent, notch absent; ventral valve tip with inconspicuous serrations restricted to very tip ( Fig. 22).

Color. Head black, mesosoma orangish brown (188, 093, 032), metasoma and legs mostly dark brown (069, 050, 024). Head: Scape apically lightest; pedicel and flagellomeres 1, 5–10 dorsally white; mouth parts whitish (218, 216, 195), except mandible apex blackish. Mesosoma: Ventrally slightly darkest; propodeal apophyses white; propleuron darker than pronotum. Legs: Fore and mid coxae and trochanters, hind trochanter basal parts ventrally, tibia basal 0.2, t2 and t3 white, except mid coxa anteriorly and posteriorly with brown mark, and fore and mid trochanters dorsally dark brown; hind coxa dark brown, except dorsal longitudinal mark orangish brown and apical margin white; trochantellus ventrally and apically, femora basal margin and ventrally, and hind t1 lightest ( Fig. 67); 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 one distinct dark spot, on apical half of cell 3M and 1+2R1, and surrounding areas; basal dark spot often minute, indistinctly or almost so, on cell 1Cu apical parts. Metasoma: Basally blackish, changing to dark brownish (084, 053, 021) towards apex; T1 ventrally lightest; T1 apical 0.2 and T2 apical 0.3 with white stripe, T2 stripe central 0.6–0.7 anteriorly concave, concavity apex reaching about half stripe width; T3–7 darkest towards base; T3–5 apical margin lightest; T6 apical margin, T7 and T8 dorsally, and sternites medially white; ovipositor sheath dark brown, except basal 0.9 ventrally whitish; ovipositor light brown (187, 144, 084).

Male. Unknown.

Variability. Supra-antennal area sometimes with almost indistinct longitudinal line. Color: Flagellomere 4 apical parts sometimes white; mesosoma color orangish brown (188, 093, 032) to brownish; extension and brightness of lightest marks on legs variable.

Comments. Included in the D. typurum species group (see item Species Delimitation). Debilos typurum is differentiated from all the other species of its species group by a combination of pedicel and flagellomere 1 white, collar without white mark, fore wing with one apical dark spot, fore and mid coxae white, except by mid one with a mark slightly brownish, hind coxa dark brown, except dorsal longitudinal mark orangish brown and apical margin white, and hind t2 and t3 whitish. If the coloration of the coxae is ignored, this color pattern may resemble that presented by D. pekujum , but D. typurum can be recognized by having the clypeus black (vs. dark brown), T1 dorsally dark brown, as darker as T2 (vs. dorsally orangish brown, lighter than T2), with spiracle not prominent (vs. inconspicuously prominent), and T2 with thyridium distinctly longer than wide (vs. subcircular).

Etymology. From the Carib word typuru, meaning “reddish brown color,” in reference to the color pattern of this species and all the other of the species group that bear its name.
