( Figs 3b View FIGURE 3 , 8a View FIGURE 8 , 12d–f View FIGURE 12 )

Diagnosis. Recognized by the following set of features: scutellum dark castaneous with three yellow patches ( Fig. 3b View FIGURE 3 ); corium with narrow patch medially, not reaching outer margin of clavus ( Fig. 3b View FIGURE 3 ); secondary gonopore undifferentiated, medial sclerotization indistinct ( Fig. 12d View FIGURE 12 ).

Description. COLORATION ( Fig. 3b View FIGURE 3 , 7a View FIGURE 7 ). Dorsum dark castaneous with yellow areas. Head. Dark red brown to entirely black; antennal segment I dark yellow tinged with red; segment II from yellow tinged with dark brown apically to entirely dark brown; segments III and IV dark brown; labium yellow with red and fuscous areas. Thorax. Pronotum. Dark castaneous. Mesoscutum and scutellum. Dark castaneous; scutellum with two patches basolaterally and one apically. Thoracic pleura. Dark castaneous; metathoracic scent gland evaporative area yellow. Hemelytron. Dark castaneous with dark yellow areas; clavus and corium dark castaneous, corium with yellow patches – one basally and other medially; embolium dark yellow; cuneus dark brown, yellow basally; membrane fuscous. Legs. Dark yellow with brown and dark brown areas. Abdomen. Dark castaneous. TEXTURE AND VESTITURE. As in generic description. STRUCTURE ( Fig. 3b View FIGURE 3 ). Thorax. Pronotum. Collar broad, about as wide antennal segment I diameter; calli broadly developed, about the same size as eye diameter. Genitalia. Endosoma simple, with well-developed, straight, medial sclerite narrowing toward apex, acute apically ( Fig. 12d View FIGURE 12 ). Left paramere when viewed dorsally ovoid, apex short and narrowed ( Fig. 12e View FIGURE 12 ). Right paramere apical process short, strongly narrowing toward apex; sensory lobe prominent, rounded ( Fig. 12f View FIGURE 12 ).

Female. Unknown.
