Redescription

COLORATION. Body red with one longitudinal black stripe arising on pronotum running along dorsum and pair of black stripes on each side of forewings. Face red with large black spot near ecdysial line; crown red with quadrate median anterior black spot, anterolateral margins weakly sinuate; ocelli black; postfrontal suture red, extended laterad of ocelli. Midline faint red, not carinate. Antennal ledge red with margin straight. Frontoclypeus red and slightly convex medially; surface weakly striated. Anteclypeus red; in lateral view straight; similar in proportions of length versus width. Gena red with lateral margin slightly acute. Lora red 2 × slender than anteclypeus mid-width. Pronotum mostly red with a black stripe on midline broadened near posterior margin. Scutellum red. Forewings black with red longitudinal stripe along claval suture continued onto inner apical cell. Abdomen mostly fuscous. Legs with femora red, tibiae and tarsi dark brown. Male genital capsule fuscous.

MALE TERMINALIA. Pygofer 1.3× as long as tall; posterior margin subquadrate with minute pointed projection near mid-length; 4 rows of 5–7 macrosetae without microsetae. Subgenital plate triangular; broader near base and strongly tapering to tip; 8–10 uniseriate macrosetae on lateral margin with few intercalated fine setae. Style narrow; surface partially smooth; base curved inwards and acute, medial anterior lobe not developed, preapical lobe strongly developed, apophysis somewhat long and wide, apex pointed. Connective stem longer than arms, 1.4 × as long as style. Aedeagus not prominent in pygofer, shaft recurved dorsad, apex broadly rounded in lateral view; base broad with basal atrial process short, curved and pointed.

FEMALE TERMINALIA. Pygofer pale with some dark distal stout elongated macrosetae, posterior margin darker and weakly pointed; sternite VI mostly pale with minute dark impressions near to posterior margin produced.
