Mesosoma:
Mesosoma length:height 1.3. Mesoscutal midlobe areolate medially, areolate-reticulate laterally, with moderately long setae; lateral lobe areolate to areolate-reticulate. Axilla areolate to areolate-reticulate; mesoscutellar disc areolate; frenal line regularly foveate; frenum areolate; axillular groove anteriorly absent, broad and foveate posteriorly; axillula areolate with longitudinal carinae. Propodeum with irregular median carina; propodeal disc areolate medially to areolate-reticulate laterally; callus areolate-reticulate, with 3–5 setae. Mesepisternum reticulate to areolate-reticulate laterally, smooth ventrally, broadly rounded anterior to mid coxa. Upper mesepimeron mostly smooth, except for small patch of weak sculpture posteriorly; lower mesepimeron reticulate to areolate-reticulate; transepimeral sulcus distinct. Metepisternum laterally smooth to weakly reticulate. Hind coxa 2.0–2.1× as long as broad; hind femur 5.4–5.5× as long as broad. Fore wing 2.5× as long as broad, 2.7– 2.8× as long as mesothorax; stigma with 4 sensilla widely separated in a row. Hind wing costal cell with 1 or 2 irregular rows of setae.
