Description. Head with five spines; frontal spines erect, short; occipital spines extremely long, porrect, nearly as long as first antennal segment, down-curved; medial spine long, porrect, nearly as long as occipital spines. Eyes small, red. Antennae moderately long; scape (segment I) infuscate, slender at base, greatly expanded on middle third, then constricted on apical third; pedicel (segment II) tan, shorter, one third length of scape; basiflagellomere (segment III) tan, slender, extremely long, more than four times longer than scape; distiflagellomere (segment IV) short, clavate, covered with fine hairs, black, basally tan. Bucculae tan, biseriate, closed apically projecting anteriorly beyond apex of frons and posteriorly over prosternum. Rostrum moderately long, extending to mesocoxae, yellow ochraceous, tip black.

Pronotum finely punctate, yellow ochraceous; paranota biseriate, each anterolateral margin with two prominent spines, one expressed anteriorly and the other laterally, irregular spines and spinules along lateral margins; pronotal hood extremely minute, low, porrect; tricarinate; median carina low, but arched in middle, uniseriate except biseriate near middle; lateral carina not as tall as median carina, uniseriate, subparallel.Triangular pronotal posterior projection unicolorous with pronotum, rugose on basal third, then gradually areolate on apex.

Hemelytra constricted, extending far beyond apex of abdomen, with spines along lateral margins; costal areas biseriate, with a few intercalary cells near hemelytral constriction; subcostal areas uniseriate at base, biseriate at middle, cells infuscate along subcostal extensions; rm veins elevated above cubital veins in lateral view; discoidal cells narrow, triseriate, each extending to middle of hemelytra; sutural areas triseriate at widest. Rostral laminae slightly elevated, uniseriate, subparallel on pro- and mesothorax, crescentic on metathorax. Legs yellow, slender; tarsi red fuscous. Abdomen narrow, ochraceous, beset with few scattered hairs; abdominal spiracular peritremes laterally projected.

Measurements. (n = 1) Length: 2.27, width at widest: 1.20, length of antennal segments one through four, respectively: 0.22, 0.10, 1.21, and 0.33.
