Head including the neck black, space between eye and ocellus and narrow longitudinal stripe running between ocelli to base of post-tylar sulcus yellow; antennal segment I dark reddish brown, II to IV dark castaneous orange; pronotum including the collar pale orange, with posterior margin, posterolateral margins and humeri including the spine black; scutellum black with apex yellow; clavus and corium black with claval and corial veins, costal border and apical angle dark castaneous orange with posterior third of apical margin yellow; connexival segments III–VII pale yellow; dorsal abdominal segments black with median pale yellow longitudinal stripe running from III to mid third of segment VII. Ventral coloration. Head, rostral segments I–IV (apex of IV brown), thoracic sterna, pro-, meso-, and metapleura and metathoracic peritreme shiny pale orange; fore and mid legs with coxae, trochanter and tibiae pale orange; femora with basal and mid third pale orange and posterior third and spines reddish brown; basal tarsus pale orange and mid and apical tarsi dark brown; hind leg with coxae, and trochanter pale orange; femora dark reddish brown with basal joint pale orange; tibiae pale castaneous brown with apical third yellow; basal tarsus yellow, and mid and apical tarsi dark brown; pleural abdominal margins III–VII yellow; abdominal sternite III yellow with lateral margins pale castaneous, sternite IV pale castaneous with basal margin near the middle yellow, and sternite V–VII dark reddish brown. The male genital capsule as figure 39. Parameres. See figures 27 and 28.

Discussion. Differential diagnosis. This species is distinguished by having the antennal segment IV uniformly dark castaneous orange; the abdominal segments black with median pale yellow longitudinal stripe running from III to mid third of segment VII; the head dorsally and ventrally black with the space between eye and ocelli, and narrow longitudinal stripe between ocelli to base of post-tylar sulcus yellow; and pronotum including the collar pale orange, with posterior margin black.
