description: Amnestus henryi sp. nov.
(Figs. 7–12)
Diagnosis: This species is distinguished by these characteristics: the fore tibia flattened with four robust spines on external margin and one on its apex, ventrally with a small spine on middle area; posterior femur with a spine near to apex on internal margin. This species is very similar to A. bergrothi Distant, but in A. henryi the parameres are elongated and have one side slightly straight (Fig. 12), whereas in A. bergrothi the parameres are not elongated and one side is rounded.
Head. Antennal segments III and IV, pronotum, prosternal carina, abdominal venter and scutellum pale brown; antennal segments I, II, and V, rostrum, clavus, corium, and legs pale yellow, posterior margin of pronotum dark brown (Fig. 7). Posterior part of head with disperse punctures; tylus with four robust pegs and with transverse rugae, not longer than jugum; antenna with five segments, second very small; rostrum longer than base of metasternum. Thorax. Pronotum with anterior margin concave and anterior half area elevated and with disperse punctures, transverse impression strongly marked; anterolateral margins entire, no carinated; posterior margin wide and convex. Propleura shiny and smooth; prosternal carina with anterior part elevated (Fig. 10); mesopleura even; evaporatorium extended, reaching posterior and lateral margins of pleura; metapleura with evaporatorium extended to posterior and lateral margins of pleura, with peritreme elongated and slightly curved apically; posterior margin toothed with a series of setigerous punctures (Fig. 11). Legs. Fore tibia flattened with four robust spines on external margin and one on its apex, ventrally with a small spine on middle area (Fig.8) Fore femur with a bifid spine on its ventral area; posterior femur with a spine closed to apex with a simple spine near to apex, on internal margin (Fig. 9). Scutellum. Triangular, with evenly distributed punctures on disc. Hemelytra. Slightly punctured surface, with basal margin entire; clavus with two rows of punctures through its first half of its length; membrane hyaline, longer than apex of abdomen; membrane hyaline. Abdomen. Shiny, ventrally convex, covered with fine hairs.
Male genitalia. Parameres elongated with middle region swallowed and slightly curved apically (Fig. 12).
