Diagnosis. Male: Two large ellipsoid-like white marks on largely black mesepisternum (Figs. 37E–F) diagnostic. Cercus in lateral view: small dorsobasal expansion present. Ventrobasal expansion triangular, occupying more than 1/2 length, angled downward at approximately 45º to reach most ventral point at mid length of expansion, then upward at equal angle to reach horizontal branch of cercus (Fig. 22B), slightly curved downward. Cercus in mediodorsal view: apical portion longest, basal portion slightly longer than medial one. Ventral expansion present and sparsely hairy on ventral border. Ventral branch of medial process fingerlike, ridge reaching tip through internal side. Dorsal branch of medial process small and roughly triangular, with two sides shorter than base, internal side sclerotized and toothed (Fig. 22A). Female not examined.
