Dorsocentrals present both anterior and posterior to transverse suture. Microtrichia cover entire wing. Prothoracic femur with long, fine, hair-like posteroventral setae. Metathoracic coxa with one lateral macroseta; trochanter blackish; femur anteriorly yellow with brown-black markings and with black and yellow/white macrosetae. Abdomen: Ovipositor relatively short and broad (length:width ratio, measured dorsally <3.3) and relatively short and deep (length:depth ratio, measured laterally <2.8). Gonocoxite length:width ratio 1.6–2.0. Distal margin of S8 with weakly developed medial process. Ventromedial area of hypandrium moderately constricted (ca. half width of lateral parts). Gonostylus shape moderately slender (viewed ventrally). Aedeagal terminal filaments moderately well developed, trifurcate. Gonostylus and gonocoxite of approximately equal length (viewed ventrally). Aedeagus straight, relatively short and laterally compressed. Epandrium distally bilobed.
