Redescription. Body 2X longer than broad ( Fig. 2A ). Tylus surpassing juga, slightly dilated apically. Posterior margins of eyes convex.

Labium reaching abdominal fifth sternite (fourth visible); ratios 1:1.8:1.4:1. Ostiole of metathoracic scent gland lenticulate; peritreme strap–shaped, curved anteriorly, apically rounded, apex deflexed away from pleura, 7–8X longer than wide, reaching 2/3 of distance from ostiole of metathoracic scent gland to lateral metapleural margin; evaporative area covering much of meso- and metapleuron. Episternal ridge located 4/5 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron.

Color and vestiture. Ground color straminous with black punctures. Entire body with piceous lateral bands. Antennae with segment I with piceous longitudinal dorsal marking; segments II–V straminous proximally becoming castaneous distally. Pronotum with triangular dark markings on posterior margin formed by high concentrations of punctures; scutellum with two dark lateral longitudinal bands. Legs mostly straminous with castaneous speckling, tibiae with two testaceous bands. Antennae with segments I–II waxy with sparse vestiture, segments III–V with dense short pile.

Male. Outer ventral rim of pygophore posteriorly produced; dorsolateral lobes short, broadly curved apically ( Fig. 3B–D ). Proctiger as wide as long; basal sclerite wider than long, posterior margin concave ( Fig. 3D ).

Female. Eighth gonocoxa broadly triangular, rounded apically, leaving most of ninth gonocoxae exposed. Ninth laterotergites elongate, distally surpassing posterior margin of eighth tergite ( Fig. 3A ).
