Plochiocoris Champion, 1900

Plochiocoris Champion, 1900: 314 . Type-species by monotypy Plochiocoris longicornis Champion, 1900 .

DESCRIPTION: Medium-sized species, elongate, not flattened dorso-ventrally. Male: Head: Smooth, shining; prominent, longer than wide ( Fig. 29 ); antennal segment II sightly less than 4.5x the length of I and longer than length of head + pronotum, with long and erect pilosity. Eyes large and nearly touching ventrally. Labium long, reaching midcoxae; segment I short, not reaching base of antennal segment I; second segment 2.5x longer than third. Thorax: Dorsally covered by erect pilosity. Pronotum with lateral margins slightly bisinuate and not carinate; posterior lobe of pronotum slightly rugose, collar absent ( Fig. 30 ). Scutellum posteriorly rugose. Hemelytra smooth, not sinuate laterally, subparallel-sided ( Fig. 31 ). Legs slender and unarmed. Vestigial pads. Ostiolar peritreme straight ( Figs. 1–2 ). Metasternum elongate and apically truncate ( Fig. 32 ). Apical margin concave. Abdomen: Genitalia with left paramere hook-like, slender, strongly curved ( Fig. 33 ); external margin rounded, internal margin deeply sinuate ( Fig. 34 ). Female: Similar coloration and vestiture to those of male. Head with small eyes not reaching ventral surface; antennal segment II more than 3x as long as I.

DISTRIBUTION: Widely distributed in Western Hemisphere.

DISCUSSION: Differs from Dolichiella by having somewhat larger eyes, with a shorter interocular space, male genitalia strongly curved, a longer penultimate labial segment, and by a smooth and apically concave metasternum.
