Diagnosis: This species resembles the most A. coibensis by its darker coloration, larger size, increased number of ommatidia on the eyes and general shape of the scent gland peritreme. It differs from this species by the even darker aspect of its habitus, and by the short hemelytra carina-like vein, which seems to be unique among its congeners. The unequally divided peritreme also differs from A. coibensis and A. zeteki , the other species bearing such unequally divided peritreme. The sinuosity of the anterior branch is more pronounced, and the tip of the anterior branch is rounded and not acutely defined as in A. coibensis , and the posterior region of the posterior branch is not enlarged like in A. coibensis and A. zeteki .

Description: Body: Dark brown; head same as body; antennae, rostrum and legs brown ( Fig. 25A View Figure 25 ). Head: Pubescent, with well-spaced hairs; clypeus slightly lighter than head; antenniferous process less than one-fourth of the pedicel length; pedicel subequal to basiflagellomere, both smaller than distiflagellomere and more than twice as big as scape; eyes with few scarcely distributed ommatidia, more than what is usually observed among its congeners; bucculae rounded, widest anteriorly, slightly concave posteriorly; with scarce hairs on its border, at least three rows of punctures not so deeply impressed, concave posteriorly ( Fig. 25E View Figure 25 ); rostrum reaching at least the third abdominal segment ( Fig. 25B, C View Figure 25 ). Thorax: Punctate, one row at collar and then only on the posterior lobe of pronotum; anterior border usually straight, posterior sinuous; paranota carinate, with hairs on its border ( Fig. 25F View Figure 25 ); scutellum conspicuously large, about one-third the maximum pronotum width ( Fig. 25D View Figure 25 ). Hemelytra: Coriaceous and coleopteroid, pubescent almost entirely, glabrous only on the middle of the hemelytra; laterally constricted anteriorly; carina-like vein extending from the anterior border to only the first third of hemelytra, smoothly fading; coarsely punctate anteriorly, up to the hemelytra constriction, completely smooth thereafter. Scent gland: Anterior branch edges sinuous and considerably enlarged if compared to posterior branch; posterior straight, edges conspicuously narrow, even narrower than sulcus; sulcus prominent on posterior branch, weakly impressed on anterior branch, fading entirely way before the tip; evaporatorium with curved border anteriorly, advancing to up to one-fourth of mesopleuron ( Figs 16F View Figure 16 – 25C View Figure 25 ).

Measurements: BL, 2.91 (2.82; 2.82–3.00 xF); BW, 1.49 (1.48; 1.48–1.50 xF); HL, 0.32 (0.29; 0.29–0.36 xF); HW, 0.55 (0.55; 0.55– xF); ID, 0.35 (0.34; 0.34–0.36 xF); PL, 0.57 (0.57; 0.57– xF); PW, 1.17 (1.16; 1.16–1.18 xF); AS, 0.15 (0.15; 0.15– xF); AP, 0.44 (0.42; 0.42–0.46 xF); AB, 0.39 (0.36; 0.36–0.42 xF) and AD, 0.51 (0.51; 0.51 xF).

Etymology: This species was named after the great American entomologist Dr Randall T. Schuh, who identified these specimens as Anommatocoris sp. and made important contributions to the study of Vianaidinae ( Schuh et al., 2006); not to mention the countless contributions to Miridae and Heteroptera in general throughout his fruitful career.
