Proamblia elongata: Bergroth 1920: 73 ; Carvalho 1957: 33, 1980a: 644; Schuh 1995: 35; Gorczyca 2006: 72 Proamblia cunealis: Gorczyca 2006: 72 , Fig. 24

Diagnosis. Recognized by having anterior lobe of pronotum relatively convex medially; posterior lobe with relatively broad, longitudinal, yellowish, slightly raised swelling contiguous with anterior lobe and terminated on posterior margin ( Fig. 2 C–D); sclerite inside endosoma widened medially and sharply terminated ( Fig. 8 F, G).

Redescription. Female. COLORATION ( Fig. 2 C–D). Head. Varying from brownish to almost entirely dark brown with paler areas; vertex sometimes with two yellow patches posteriorly almost contiguous with margin of eye; antennal segment I dull yellowish slightly tinged with red, paler basally; segment II (excluding apex) brownish, gently tinged with yellow; labial segment I sometimes slightly tinged with red. Thorax. Pronotum. Ranging from brownish to almost entirely dark brown with yellow markings; yellow marking on calli hardly present in medially or broad, almost entirely occupying calli; posterior margin always with broad, longitudinal stripe contiguous with anterior lobe and terminated on posterior margin, sometimes yellow patches on sides of the stripe are also present. Mesoscutum and scutellum. Scutellum slightly tinged with red, and with dark, longitudinal stripe in medially of scutellum broad, sometimes scutellum almost entirely dark, always yellow apically. Hemelytron. Yellow transverse patch near medially spreading onto medial fracture, occupying most of its length; clavus slightly tinged with yellow apically; cuneus ranging from yellow with dark brown patch on lateral margin to almost entirely brown, inner angle of cuneus sometimes slightly tinged with red. Thoracic pleura. Proepimeron ranging from pale brown to almost black, paler posteriorly; mesepimeron dark brown, paler posteriorly varying from yellow to brown; metepisternum ranging from entirely yellowish with dark patch to dark brown with blackish areas with large, yellow, longitudinal stripe; scent-gland evaporatory areas and peritreme yellow. STRUCTURE AND VESTITURE ( Fig. 2 C–D, 7A–E). Thorax. Pronotum. Calli somewhat convex; anterior lobe slightly carinate laterally; posterior lobe with indistinct longitudinal swelling medially.

Male. Similar to female in overall appearance, but slightly smaller.

Male genitalia ( Fig. 8 ). Endosomal sclerite broadened medially and sharply pointed apically.
