Amnestus brailovskyi Mayorga & Cervantes, 2005 , 159–166

Diagnosis. Tylus convex, transversely rough, except apical lobe, juga and anterior half of pronotum with sparse punctures; anterior margin of pronotum concave, delimited by a series of setigerous punctures. Ventral margin of prosternal carina rounded. Body length 2.8 mm. This species is similar to A. calakmulensis , but the tylus on A. brailovskyi has transverse impressions, while A. calakmulensis lacks them.

Description. Head, III, IV, and V antennal segments, pronotum, scutellum, and abdomen dark brown. Hemelytra, legs, and rostrum pale yellow.

Head. Anterior half without punctures, tylus transversely rough except apical lobe, which has four fine and long spines; rostrum short reaching base of mesosternum. Thorax. Pronotum with anterior margin concave, delimited by a series of setigerous punctures, anterior half elevated with sparse punctures, anterolateral margins slightly explanate, posterior half densely punctuated. Propleura dull and smooth, prosternal carina low and with ventral margin lobulate. Mesopleura with evaporatorium expanded towards posterior and lateral margins. Metapleura flat with evaporatorium reaching middle part of pleura, peritreme elongated with dark brown border, posterior margin of evaporatorium with setigerous punctures well defined. Legs. Fore tibiae with five spines on dorsal margin; femora with a bifid long spine on posterior mesial region of ventral surface; ventral and dorsal margins of femora smooth, with a simple spine near apex on ventral surface. Scutellum. Triangular, with acute apex, disc dark brown with sparse punctures. Hemelytra. Corium with regularly distributed punctures, clavus with three rows of punctures; membrane hyaline, slightly passing apex of abdomen. Abdomen. Ventrally convex, and covered by fine hairs. Male genitalia. Parameres large and broad with acute apex, and three long setigerous punctures on central area.
