Description
Male: General body shape oval. Dorsum dark reddish brown with yellow and red markings on the hemelytra and pronotum. Head lighter in color than rest of body; with sporadic, fine concolorous punctures at base, between eyes. Paraclypei contiguous beyond anteclypeus, lateral margins concave, narrower towards apex, with transverse oblique rugae. Anteclypeus small, triangle in shape, immaculate. Eyes very prominent; ocelli large, reddish, located near base of anteclypeus. Antennae concolorous with rest of body. First antennomere reaching to near apices of paraclypei. Apical two antennal segments missing in holotype. Rostrum short, reaching half way between procoxa and mesocoxa, second segment curved, last two segments subequal in length, shorter than second segment.
Pronotum hexagonal with sparse fine punctures. Anterolateral pronotal margins with a submarginal yellowish band, transversely rugose. Humeral angles somewhat prominent, produced beyond base of coria by about the diameter of eye, subhumeral lobe with a short process, posterior pronotal margin biconcave basally. Cicatrices unpunctated. Scutellum triangular in shape, with sparse fine punctation and transverse rugae basally, most noticeable near basal angles; apex depressed, not reaching beyond corial apices. Clavus margined with yellowish band similar to that on pronotum, with a fine line of punctures. Hemelytra finely sculpted, surrounded by a yellowish band, with dendriform red markings. Evaporatorium rugose; ostiole elongated, ostiolar peritreme longer, vermiform, fleshy; ostiolar plate immaculate. Legs light brown with short yellowish-brown pilosity on the femora and tarsi, trochanters each with a small hook at base.
Abdominal dorsum iridescent green, connexiva exposed, not covered by hemelytra, with dentate margins and yellowish and reddish transverse bands. Abdominal venter reddish-brown, uniformly colored. Abdominal spine thick at base, reaching procoxa. Spiracles black, each on a slightly elevated callus, concolorous with rest of abdominal venter. Male genitalia (Figs. 4, 7): pygophore ventrally brownish, darker posteriorly, with ventral margin slightly bilobed, overall concave. Posterolateral angles rounded, prominent, with yellowish-brown pilosity. Parameres cane-shaped (with curved apex) with straight margin at the base.
Measurements (n=1): Total length: 19.89; head length: 1.90; head width: 3.08; pronotum length: 5.44; pronotum width: 11.61; scutellum length: 7.71; scutellum width: 6.43; antennae: I=1.29, II=3.28, III=4.33, (remaining segments missing); rostrum: I=1.44, II=2.27, III=0.87, IV=0.98.
