Dolichiella Reuter, 1908 , restored to generic rank

Dolichiella Reuter, 1908: 6 . Type-species by monotypy Dolichiella pilosa Reuter, 1908 (Synonymized with Plochiocoris Champion by Carpintero, 2002: 29).

DESCRIPTION: Medium-sized species, elongate, not flattened dorso-ventrally, densely pilose on dorsal surface. Male: Head: Smooth, shining; prominent, longer than wide; antennal segment II more than 4.5x the length of I, and longer than length of head + pronotum, with long and erect pilosity. Eyes large but smaller than in Plochicoris, nearly touching ventrally and removed from pronotum by a distance equal to 75% the length of one eye. Labium long, reaching the midcoxae; segment I short, not reaching the base of antennal segment I; second labial segment twice the length of third ( Fig. 22 ). Thorax: Dorsally covered by erect pilosity. Pronotum short, with posterior margin concave and twice the width of anterior margin; lateral margins slightly sinuate but not carinate; calli smooth, slightly elevated, with a narrow longitudinal sulcus. Posterior lobe of pronotum rugose, collar absent ( Fig. 23 ). Scutellum smooth and with long and erect setae. Hemelytra smooth, opaque, anterior margins not sinuate, subparallel-sided ( Fig. 25 ). Apices of endo- and exocorion of the same width. Cuneus long, membrane dark, long, extending beyond the apex of cuneus by a distance equal to the length of this. Legs slender and unarmed ( Fig. 24 ). Vestigial pads. Ostiolar peritreme straight but posterior margin slightly concave. Metasternum sulcate medially, elongate and apically truncate with its apical margin straight ( Fig. 26 ). Abdomen: Genitalia with left paramere hook-like, wide, not of Orius - type, i. e. spiraled ( Fig. 27 ); externally straight, angular, internal curvature shallow ( Fig. 28 ). Female: Similar to male in coloration and vestiture. Head with small eyes not reaching the ventral surface and separated from pronotum by a distance equal to the length of one eye; antennal segment II more than 3x the length of I.

DISTRIBUTION: Central and South America.

DISCUSSION: Differs from Plochiocoris by having somewhat smaller eyes and a longer interocular space, male genitalia more strongly angular, a shorter second labial segment and by the metasternum’s being sulcate medially and apically straight.
