The genus Pachymeroceroides

The monotypic genus Pachymeroceroides was created by Carvalho & Gomes in 1971, to include the only species, Eurycipitia bromelia , described by Carvalho (1946) based on 11 males and 20 females. The chief character which distinguishes Pachymeroceroides from other genera of the tribe is the presence of a deep fossa in the hemelytra exocorium of males.

Diagnosis. Bryocorinae . Eccritotarsini . Body shining with metallic bright. Hemelytra with a deep fossa in hemelytra region of exocorium of male. Cuneus rounded apically. Cubital vein with dense pilosity.

Redescription. Specimens of small size (4.0 mm, on average). Body shining metallic covered with short setae; dorsal surface smooth. Head uniformly dark with dense pubescence, longer than wide, somewhat inclined anteriorly; clypeus slightly convex, well delimited, with lateral margin almost parallel; rostrum extending between hind coxae; eyes sessile, occupying most of height of head in lateral view, contiguous to anterior margin of pronotum. Antennal III and IV thinner than I and II. Pronotum faintly punctuated, covered with dense and adpressed pubescence; anterior and humeral angles rounded; collar larger than width of antennal segment I; calli convex and well-delimited; discal area convex, higher than hemelytra. Hind femur larger in its apical 1/3, with three long erect setae at apex; tibiae covered with dense and short pubescence equal or shorter than width of segment. Mesoscutum covered by posterior margin of pronotum. Scutellum shining, covered with scattered pilosity and with a “V” basal depression. Hemelytra smooth, metallic shining, reaching beyond apex of abdomen; lateral margins somewhat parallel. Males in the median portion of their exocorium with a conspicuous fossa-like depression; aedeagus without character structures to distinguish both species of the genus. Parameres asymmetric, left longer than right as in most mirids. Membrane dark with cubital vein salient covered with short hair.
