Description

TOTAL LENGTH. Between 6.3 and 6.6 mm.

HEAD. In dorsal view ( Fig. 3A, C ), median part of vertex with small triangle, indistinct, on lower margin. Ocelli separated by thin carina. Lateral part of vertex curved on upper part and flattened on anterior margin of head. Postclypeus slightly convex forming obtuse angle in lateral view. Postclypeus with triangle dimple below frons-postclypeus suture with clear sulciform mark on middle.

THORAX. Anterior part of pronotom with very thin carina.

MALE GENITALIA. Subgenital plates long, reaching dorsal third of pygofer, strongly curved; diameter decreasing gently toward tip, which is rounded and covered with short setae ( Fig. 3E ). Dorsal margin of parameres possesses two rounded extensions: anterior than other. Sterno-lateral plates wide and exceeding pygofer with triangular shape with dorsal and ventral junction convex and oriented posteriorly ( Fig. 3G ). On ventral part of parameres, anterior and posterior margins mainly parallel with junction forming rounded endpoint. Aedeagus ( Fig. 3F ) not exceeding height of pygofer. Anterior margin of aedeagus with successively (from base to apex) short bump, small membranous part and with two spined excrescences, lower one being longer. Ventral margin extending in very convex arc. Dorsal part of aedeagus arced in obtuse angle. Apical part of aedeagus bifid with anterior thin spine-like extension and a posterior wider extension with rounded apex; anterior extension one third length of posterior one.

COLORATION. Head and anterior third of pronotum uniformly dark brown. Middle of pronotum with continuous transverse yellow stripe ( Fig. 3A–C ). Rest of pronotum and scutellum dark to light brown. In ventral view, thorax dark as head ( Fig. 3B ). Abdomen and legs reddish brown with tarses dark brown or black ( Fig. 3B–C ). Tegmina brown or slightly clearer than rest of body. Tegmina with two distinct yellow bands ( Fig. 3A–B ): one extending over clavus, starting from insertion of tegmina to apical part of PCu; other extending on corium between M and Cu. Insertion of tegmina reddish or light brown.
