Anommatocoris minutissimus, China, 1945

Anommatocoris minutissimus View in CoL

China, 1945 ( Fig. 24 View Figure 24 )

Diagnosis: This species is distinguishable from the other Anommatocoris species by the lack of acute humeral angle, the lightly pronounced punctations on pronotum, the narrow scutellum and the scent gland peritreme, which is similar to the one presented by A. coibensis due to the almost straight upper part of the anterior branch, but it is equally divided by the posterior branch and lacks a sinuous margin.

Redescription: Body: Light brown; antennae, rostrum and legs even lighter; head whitish ( Fig. 24A View Figure 24 ). Head: Pubescent, with small and well-spaced hairs; clypeus darker than head, same colour as body; antenniferous process half of pedicel length; pedicel twice the size of scape; eyes with just a few scarcely distributed ommatidia; bucculae rounded, widest anteriorly, with scarce hairs on its border and fine marks of punctures organized in a single complete row in the middle, concave posteriorly ( Fig. 24D View Figure 24 ); rostrum reaching at least second abdominal segment ( Fig. 24B View Figure 24 ). Thorax: Finely punctate, with tiny punctures on collar and on the posterior lobe of pronotum; anterior border concave, posterior only slightly sinuous; paranota carinate with hairs on its border ( Fig. 24E View Figure 24 ); scutellum large, a little less than one-sixth the maximum pronotum width ( Fig. 24C View Figure 24 ). Hemelytra: Coriaceous and coleopteroid, pubescent mostly on subcostal and costal areas; laterally constricted anteriorly; carina-like vein extending from the anterior border to the middle of hemelytra, fading abruptly; finely impressed by punctures anteriorly up to the hemelytra constriction, smooth posteriorly to the hemelytra constriction, bearing punctures marks but not punctures. Scent gland: Anterior branch tip tilted horizontally, large, slightly smaller than the rest of the anterior branch, presenting a lightly cracked texture; posterior branch straight, with evenly enlarged edges through its whole extant; sulcus much more prominent on posterior branch than in anterior branch; evaporatorium with curved border anteriorly, advancing to up to one-third of the mesopleuron on its upper part ( Figs 16E View Figure 16 – 24B View Figure 24 ).
