Anommatocoris zeteki View in CoL

Drake & Froeschner, 1962 ( Fig. 28 View Figure 28 )

Diagnosis: Anommatocoris zeteki can be identified by the colour of the head, the lightly pronounced humeral angle, the relatively large scutellum, the carina-like vein reaching the middle of the hemelytra and the scent gland unequally divided as in A. coibensis and A. schuhi . It differs from these two species in the degree of development of such traits, on the body length and width remarkably smaller, and by the almost straight and with enlarged edges anterior branch of the peritreme.

Redescription: Body: Brown; head, same as the body; antennae, rostrum and legs lighter ( Fig. 28A View Figure 28 ). Head: Pubescent, with small and well-spaced hairs; clypeus lighter than head, same colour as antennae; antenniferous process about one-third of pedicel length; pedicel more than twice the size of scape; eyes with just a few scarcely distributed ommatidia; bucculae rounded, widest anteriorly, with scarce hairs on its border and punctures organized in a single row in the middle with a couple of extra punctures above, slightly concave posteriorly ( Fig. 28E View Figure 28 ); rostrum reaching at least third abdominal segment ( Fig. 28B, C View Figure 28 ). Thorax: Finely punctate, with fine punctures on collar and on the posterior lobe of pronotum; anterior border straight, posterior sinuous; paranota carinate culminating in a small humeral acute angle ( Fig. 28F View Figure 28 ), with hairs on its border; scutellum large, less than one-third of the maximum pronotum width ( Fig. 28D View Figure 28 ). Hemelytra: Coriaceous and coleopteroid, pubescence apparently concentrated on subcostal and costal area, with some few scattered hairs in the middle of the hemelytra; laterally constricted anteriorly; carina-like vein extending from the anterior border to the middle of hemelytra, fading abruptly; punctures on anterior part up to the hemelytra constriction, completely smooth posteriorly to the hemelytra constriction. Scent gland: Anterior branch with slightly sinuous edges, these considerably enlarged if compared to posterior branch, tip slightly tilted horizontally; posterior straight, edges conspicuously narrow, bottom edge three times as wide as upper edge; sulcus prominent on posterior branch, weakly impressed on anterior branch; evaporatorium with straight border anteriorly, advancing to slightly less than one-third of mesopleuron ( Figs 16I View Figure 16 – 28C View Figure 28 ).
