Type species: Gigantometopus rossi Schwartz & Schuh 1990 . Diagnosis. Differs from other genera in the tribe Gigantometopini by the large body (more than 5 mm), mostly punctate dorsum, with dense, long, golden setae; the straight vertex, slightly protruding above eye level, narrower than compound eye width; compound eye large, slightly less than 1/2 head height in lateral view; frons rugose and punctate; second antennal segment longest; pronotum large, distinctly elongate, campanulate, 1/3 as long as body length, mesal length more than 1/2 posterior width, lateral margin weakly constricted, posterior margin concave at the middle, anterior part covered with golden and silvery setae; calli region swollen, with one distinct fossa in the middle; scutellum large, heart-shaped, almost as long as 1/2 hemelytra length, tumid, attaining height of pronotum, deeply punctate, pale; combined length of pronotum and scutellum subequal to 1/2 body length; commissure markedly short. Description. See Schwartz & Schuh (1990) for original description. Note. We do not consider the much smaller (i.e., 3 mm) G. schuhi Akingbohungbe congeneric with G. rossi and G. coronobtectus sp. nov. , even though we included this species in the key. This genus is distinguished from Astroscopometopus by the body stout; rugose and distinctly punctate head; large compound eye, the medial length subequal to 1/2 head length; fovea antennalis at middle of the ventral margin of compound eye and apex of clypeus; large pronotum and scutellum (subequal to 1/2 body length); the distinctly punctate scutellum, attaining the height of pronotum; and the short commissure.
