Redescription. Male. Dorsal coloration. Head, including the neck, black, tinged with metallic bluish green reflections, space between eye and ocelli, and narrow longitudinal stripe running between ocelli to apex of tylus yellow; antennal segment I dark castaneous, basal third black, segments II–IV dark reddish brown; pronotum shiny castaneous orange, densely tinged with metallic bluish green reflections at collar, anterior lobe, calli, posterolateral and posterior margin; scutellum shiny castaneous orange densely tinged with metallic bluish green reflections; apex yellow; clavus and corium dark castaneous orange with metallic bluish green reflections; hemelytral membrane brown with basal angle darker; connexival segments III–VI yellow, VII yellow with posterior border brown; dorsal abdominal segments pale brown with scars of scent glands IV–V, and V–VI orange. Ventral coloration. Head including buccula and rostral segments I–IV (apex of IV black) yellow to pale yellowish orange; propleura metallic bluish green reflections with anterior spot shiny castaneous orange; meso-, and metapleura shiny castaneous orange with acetabulae and posterior margin densely tinged with metallic bluish green reflections; pro-, meso-, and metasternum shiny castaneous orange; metathoracic peritreme pale orange; each leg shiny pale castaneous orange; spines reddish brown; hind coxae pale castaneous orange with narrow pale brown stripe; abdominal sterna shiny orange with pleural margins yellow; genital capsule shiny orange with lateral angles yellow, and middle third with dark brown irregular spot.
