Anommatocoris coleopteratus View in CoL

( Kormilev, 1955) ( Fig. 22 View Figure 22 )

Diagnosis: This species is the only Anommatocoris species with a visible scent gland in dorsal view. It also presents an unusually large tip of the anterior branch of the peritreme for the genus and a long carina-like vein on the hemelytra, reaching its posterior region.

Redescription: Body: Light brown; head whitish; antennae, rostrum and legs yellowish ( Fig. 22A View Figure 22 ). Head: Pubescent, with small and well-spaced hairs; clypeus darker than head, same colour as body; antenniferous process length more than half of pedicel; pedicel subequal to basiflagellomere, both smaller than distiflagellomere and at least twice as big as scape; eyes with few scarcely distributed ommatidia; bucculae rounded, with scarce hairs on its border and deeply impressed punctures near head insertion, concave posteriorly ( Fig. 22E View Figure 22 ); rostrum reaching at least second abdominal segment ( Fig. 22B, C View Figure 22 ). Thorax: Punctate, with small punctures, one row at collar and then only on the posterior lobe of pronotum; anterior border straight, posterior sinuous; paranota carinate with hairs and few irregularly distributed small scale-like projections on its border ( Fig. 22F View Figure 22 ); scutellum large, a little less than one-fifth the maximum pronotum width ( Fig. 22D View Figure 2 ). Hemelytra: Coriaceous and coleopteroid, evenly pubescent; laterally constricted anteriorly; carina-like vein extending from the anterior border to the posterior third of hemelytra, fading abruptly; finely punctate entirely, punctures small, larger anteriorly, up to the hemelytra constriction. Scent gland: Anterior branch tip tilted horizontally, large, same size as the rest of the anterior branch, presenting a cracked texture; posterior branch slightly curved, with considerably enlarged bottom edge on its tip; sulcus prominent on both branches; evaporatorium with curved border anteriorly, advancing to most of the upper part of the mesopleuron ( Figs 16C View Figure 16 – 22C View Figure 22 ).
