Thoracic sterna black with median pale markings ( Fig. 1B ). Median process of pygophore vertical and truncated ( Figs. 2A–B ), apical process of the dorsal phallothecal sclerite with a short-recurved spine ( Figs. 2E–F ).

Dorsal color black with pale yellow markings along inner margin of eyes and longitudinal faint stripe between ocelli; sides of head black with yellowish markings on mandibular plate and posterior rounded area behind eyes; gula yellow. Head with intermixed recumbent and erect yellowish setae. Antenna: scape black with three yellowish bands, first at middle of basal half, and remaining two at middle of apical half and at apex; pedicel black with a yellowish band at middle; flagellomeres yellowish brown. Scape with sparse short recumbent and erect setae; pedicel with more abundant erect setae, flagellomeres with abundant short decumbent setae. Antennal segment lengths: scape 2.87, pedicel 1.50, basiflagellomere 1.65, distiflagellomere 0.99. Ocelli slightly elevated on a tubercle, distance between ocelli longer than distance between ocellus and eye.

Thorax. Pronotal length 2.49, width 3.06. Anterior pronotal lobe rounded with medial longitudinal sulcus deeply impressed, not extending into posterior lobe. Anterior lobe of pronotum black with lateral pale orange strip reaching anterolateral tubercles ( Fig. 1 , A), covered with abundant intermixed recumbent and long erect setae. Posterior pronotal lobe flattened, dark brown medially, pale orange laterally, with triangular pale-yellow mark medially on posterior margin ( Fig. 1A ), with semierect setae less abundant than on anterior lobe. Humeral angles rounded, posterior margin sinuous. Scutellum black with a pale-yellow strip at base of Y-shape carina, with long erect setae. Propleura with orange spot on proepimeron, proepisternum orange to dark brown to the venter. Meso and metapleura blackish. Pleurae with sparse long erect setae and irregular patches of recumbent setae. Acetabular areas with a whitish mark. Prosternum pale yellow, meso and metasterna black with central pale yellowish marks ( Fig. 1B ). Sterna with long erect setae. Legs mostly black; coxae black with ventral pale markings; trochanters black with lateral pale markings; femora black with narrow pale base and a pale yellowish spot on dorsal surface; tibiae annulated, black and white, apical band diffuse black, tibial spur and apex black; third tarsal segment as long as first and second combined, second and third tarsal segments with darker apices on anterior and middle legs, homogeneously colored on posterior leg. Legs with intermixed recumbent and erect setae, more abundant ventrally. Hemelytron smoky brown, shiny, corium and clavus with abundant short recumbent setae.

Abdomen. Abdominal width 2.82. Abdominal terga black with lateral margins next to pale areas of connexivum paler. Venter orange red to reddish brown on lateral margins, with short erect setae. Connexivum bicolored, dorsal laterotergites with anterior areas blackish, posterior area whitish, ventral laterotergites with smaller anterior blackish areas. Male genitalia ( Fig. 2A‒F ): Pygophore mostly rounded, transverse bridge (br) dorsally elevated ( Fig. 2A ); area surrounding paramere socket (ps) postero-laterally produced with long setae ( Figs. 2B‒C ); median process of pygophore (mpp) vertical and truncated apically ( Figs. 2A‒B ). Aedeagus: Arms of articulatory apparatus (apt) abruptly curved and long in dorsal view, ponticulus basilaris absent ( Fig. 2D‒F ); dorsal phallothecal sclerite (dps) wide basally, tapering apically with a short recurved spine ( Figs. 2 E, F ); endosoma with a median (mel) and two lateral spined lobes (lel) ( Figs. 2D‒F ).

Paratypes: Males with same characteristics as holotype, except for some specimens with ventral pale markings on femora ( Fig. 1B ). Females with these pale markings more conspicuous and more extended. Triangular pale-yellow mark on posterior margin of pronotum more evident. Female genitalia ( Figs. 2G‒J ): gonocoxite VIII trapezoidal, erect setae in middle area and posterior margin; gonapophysis VIII subtriangular with numerous erect setae in posterior margin ( Fig. 2H ); gonocoxite IX subtriangular with setose apex rounded ( Fig. 2I ). Syntergite IX+X wide, trapezoid and covered with erect setae ( Fig. 2J ); bursa copulatrix not examined.
