Head 1.19 × as wide as high, 1.9 × as high as long; IOS 0.61 × head width, 1.23× eye length; OOL>POL in ratio of 29.4: 22.0 (LOL not visible in the image); OOL 3.34 × OD; eye (L: W = 68.1: 40.2) setose; frons with oblique carinae directed towards anterior ocellus; space between carinae smooth with long brown setae; vertex and interocellar area smooth with sparse setigerous punctae; interantennal process rectangular, smooth with a medial longitudinal carina; occiput entirely smooth with sparse setigerous punctae, except for a small patch of dense setigerous foveae medially; gena longitudinally carinate with setigerous punctae; ocelli raised above surface of vertex; antennomeres not clearly visible.

MESOSOMA (Figs 17, 18A, C). Cervical pronotal area transversely carinate; mesoscutum (L:W = 104.4:127.9) laterally smooth with setigerous punctae, anteromedial ¾ areolate, remaining ¼ smooth with sparse longitudinal carinae; adjoining this medial patch, longitudinal carinae extend for almost entire length of mesoscutum; mesoscutum laterally smooth with sparse areolae and setigerous punctae; pronotal shoulders with a blunt spine visible when viewed dorsally; lateral pronotal area anteriorly foveate; posteroventral margin of lateral pronotal area extending as a blunt spine; netrion foveate; dorsal mesopleuron with a small triangular rugose patch beneath tegula; mesopleural pit distinct; speculum with weak transverse carinae; mesepimeral sulcus not foveate; posteroventral femoral depression with transverse carinae; episternum and ventral mesopleuron densely setose, obscuring sculpture; metapleuron anteriorly and ventrally densely setose, remainder with large depressions; scutoscutellar sulcus laterally with large foveae; mesoscutellum (L:W = 36.7: 88.2) areolate; a median keel present; metascutellum foveate and posteromedially with a triangular spine, metanotal trough foveate; lateral propodeal area laterally densely setose, remainder smooth, except for foveae present along posterior margin; lateral propodeal area extending posterolaterally as a blunt straight spine. Fore wing (L:W = 142: 45) and hind wing (L: W = 122:30) weakly infuscate.

METASOMA (Figs 17, 18B). L:W = 251.2: 140.3; T1 longitudinally costate, space between costae weakly foveate; T2 with basal foveae, remainder longitudinally costate, space between costae smooth; T3 longitudinally costate on anterior 4 /5, sublaterally areolate, and laterally, posteromedially and posteriorly smooth; space between costae with small foveae medially; T4 medially smooth, setose, remainder with setigerous foveae; T5 and T6 predominantly with setigerous foveae; T7 setose; T1 and T2 with sparse long setae laterally, T3–T6 densely setose laterally; length and width of tergites T1–T 7 in ratio of 46.3: 37.8, 62.2: 51.2, 72.0: 115.8, 37.8:136.5, 19.5: 101.2, 11.0: 60.9, 73.2:36.5, respectively.

Remarks

Kieffer erroneously referred to the holotype as a female specimen in his type information, although later in the description of the genus he stated that females are unknown.
