PLOCHIOCORINI new tribe

Type-genus: Plochiocoris Champion, 1900 .

DIAGNOSTIC CHARACTERS: Habitus less robust than in Lasiochilini , the morphology of left paramere, extremely curved (but not spiraled as the Orius - type); right paramere short but present in Dolichiella . Ostiolar peritreme straight but directed posteriorly; metapleura with mushroom processus forming rounded alveoles; legs of males with forefemora not widened, foretibiae, forecoxae and foretrochanters unarmed, and with vestigial pads. Marked sexual dimorphism, especially of head (see under key and generic description). Males have no particular modifications on sixth and seventh sternites. Females lack a parietovaginal gland but have the typical punctures on seventh sternite. Macropterous forms only.

DISCUSSION: The genera Plochiocoris Champion, 1900 and Dolichiella Reuter, 1908 were described on the basis of the external characters of a few specimens. These genera were not redescribed posteriorly and the genitalia were never studied. Both genera may be easily distinguished from other Lasiochilinae by the strongly curved left paramere of the male, the strong sexual dimorphism evident in the head and pronotum, the unarmed legs of males and the ostiolar peritreme not curving posteriorly.
