Flat in lateral view, with conspicuous punctures. Eye elliptical. Clypeus flat, protruding medially. Epistomal declivity of clypeus divergent, arched and short. Mandible with five teeth. Antenna elbowed, articulated above level of mesosoma, without some longer setae, inserted at level of midline of eye. Scape long. Pedicel as longer than wide. Flagellum with 11 meres. Flagellomeres each longer than wide, evenly wide along length. First flagellomere short. Distal most flagellar article longest. Subocular groove absent. Malar space at least 3 times greater to basal mandibular width. Gena wide, nitid. Occipital carina present as fine ridge and completed dorsally.

Higher than long, with inconspicuos punctures dorsally, slightly areolate ventrally. Mesosoma higher than head. Pronotum dorsally obscure in midline, with fine, irregular striae laterally. Mesoscutum raised in midline; lateral carina complete from anterior to posterior margin; notaulus inconspicuously sinuous, posteriorly with dilation conspicuous, convergent and joined at scutellar groove; parapsidal furrow inconspicuous as a fine ridge, complete to anteroposteriorly region. Scutellar groove scrobiculate laterally. Metanotum scrobiculate, partially covered by scutellum anteriorly. Mesopleuron higher than wide, mostly without sculpture; anterodorsal corner scrobiculate; anteriorly polished; posteriorly with a even scrobiculate line; anteroventral margin finely scrobiculate; ventrally most polished. Metapleuron strongly sculptured, mostly areolate, with some punctures ventrally. Propodeum short, less than half length of petiole, not raised to metanotum; dorsally with areolated to rugulose sculpture laterally polished; propodeal area ventral to petiole flat. Distance between mid and hind coxae less than distance between fore and mid coxae. Hind coxae mostly rugulose. Hind leg faintly imbricate, without some longer setae. Hind tibia and tarsus without conspicuous spines. Internal tibial spur length almost two times greater than external tibial spur. Tarsal claw with apical tooth greater than subapical tooth.

Fore wing with six cells enclosed by tubular veins. 1st subdiscal cell open, 2A and 2cu-a absent. First marginal cell digitiform. Ventral margin of apex angulated, with angulation more opened. Abscissa between r-rs and 1R1 vein almost straight. 2R1 vein greater than first marginal cell length. R-m vein absent. Stigmal vein shorter, less than first submarginal cell length, narrowing posteriorly. 2Mb and 3M vein spectral. 3CU vein nebulous. 1RS vein attached to Sc+R at stigmal vein. Hind wing without jugal lobe and with three adjacent hamuli. M+CU vein absent.

Elliptical. Petiole arched, dorsally with striae, dorsally without lateral expansion.

Not dissected.

(VEN) can be distinguished from other species of Alobevania by the arched epistomal declivity of the clypeus; notaulus inconspicuously sinuous; metapleuron ventrally with some punctures, dorsally with areolate to rugulose surface sculpture; fore wing with ventral margin of apex angulated, 3CU vein nebulous.
