Diagnosis.

Male. Body length 8.5-10.2 mm. First flagellomere 1.2 × flagellomere 2. POL:OOL = 0.36. Distance between outer ocellar margins equal to distance between posterior ocelli and posterior border of occiput. Mandible bidentate apically, with subbasal tooth on outer margin beneath. Metasomal sternum 2 (except apical third) with strong longitudinal median carina highest apically. Female unknown.

Description.

Male. Body length 8.5-10.2 mm. Black with ferruginous metasomal terga 1-2, sterna 1-3, and base of terga 3 and 4. Head, mandible and scape with yellowish, dense, subappressed setae; pronotum dorsally, mesoscutum, scutellum and metanotum medially with subappressed and erect golden setae, longer on scutellum and metanotum, posterodorsal margin of pronotum densely fringed; propleuron, mesopleuron, and propodeum laterally with whitish appressed and subappressed setae, denser on mesopleuron; posterior propodeal slope with whitish yellow, sparse, erect setae; dorsal propodeal slope with short appressed white setae; legs with dense pale yellow, suberect setae. Metasomal terga with appressed and erect yellowish setae, apically sparsely fringed with pale yellowish setae, sterna with sparse subappressed yellowish setae. Metasomal tergum 2 laterally with felt line, sternum 2 without lateral felt line.

Relation of head width and mesosoma width including tegulae 55:60; relation of maxillary palpus length and cardo length 5.0:1.5. Mandible bidentate apically, with subbasal tooth on outer margin beneath and dorsal carina extending from base to subapical tooth. Clypeus with median area subtriangularly raised, anterior margin with two denticles, distance between them much less than between denticle and base of mandible. Scape not widened apically, bicarinate beneath. First flagellomere 1.2 × flagellomere 2; antennal scrobe carinate above. Ocelli small, POL:OOL = 0.36. Distance between outer ocellar margins equal to distance between posterior ocelli and posterior border of occiput. Frons and vertex with shallow dense punctures. Tegula large, not projecting scuto-scutellar suture, with smooth and shiny disc and posterior border. Mesoscutellum evenly convex. Notauli well developed, half length of mesoscutum. Parapsides poorly defined. Metanotum densely punctured, medially with deep glabrous area medially. Pronotum and mesopleuron with large, sometimes confluent punctures; mesoscutum with moderately coarse, more or less separated punctures; mesoscutellum with moderately coarse, somewhat confluent punctures; propleuron obscurely striato-punctate; inferior portions of metapleuron glabrous and shiny. Propodeum reticulate, more finely so laterally, and with larger reticulae dorsomedially.

Fore wing fuscous, first submarginal cell large, subtriangular, apically acute, 0.8 × length of marginal cell; second submarginal cell receiving recurrent vein at midpoint; third submarginal cell less distinct than submarginal cell 2 and receiving recurrent vein at midpoint. Pterostigma length equal to distance between origin of RS1 on SC and pterostigma.

Carina on metasomal sternum 1 well developed, straight, 0.8 × length of sternum 1 in profile, straight; sternum 2 (except apical third) with strong longitudinal median carina highest apically. Terga 1-6 and posterior halves of sterna 3-6 with moderately fine, well separated punctures, larger on tergum 2; sternum 2 with large, moderately coarse, separated punctures; sternum 8 (hypopygium) and tergum 7 (except apical part) with moderately coarse, dense punctures; tergum 7 medially with longitudinal narrow glabrous area up to apical fourth where it with small punctures.

Female. Unknown.

Etymology.

The specific name is a Latin adjective meaning “abnormal”, with reference to the unusual carina on metasomal sternum 2, like that of males of Zeugomutilla Chen, 1957.
