Antennomere III longer than II. Pronotum with smoky stripe reaching posterior margin. Thoracic and abdominal pleurites and sternites with black spots ( Fig. 2D ). Anterior excavation of metasternal process harboring fourth and almost whole third rostral segment ( Fig. 10F ). Male genitalia. Pygophore ( Figs 10A–D ). Posterolateral angles developed, bent inwards ( Fig. 10A ). Superior process of genital cup bilobate, short and close to proctiger; inner and outer ends projected ventrally ( Figs 10C,D ). Paramere with two lobes; anterior lobe developed, triangular and directed to base of proctiger; lateral lobe large and rounded ( Figs 10C,D ). Proctiger with scattered setae on lateral excavation; posterior face subtriangular ( Figs 10A–C ). Ventral rim with expansions acuminate, ventrolateral side gently impressed, dorsal side with brown spot on margin; barely surpassing level of posterolateral angles ( Fig. 10B ). Female genitalia . Genital plates ( Fig. 10E ).
