( 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. FIGURE 7. Amnestus henryi sp. nov. Male. Male genitalia. Parameres elongated with middle region swallowed and slightly curved apically ( Fig. 12 ).
