Prolygus Carvalho, 1987 View in CoL View at ENA
Prolygus Carvalho, 1987: 137 View in CoL (original description), type species by original designation: Lygus papuanus Poppius, 1914: 353 .
Prolygus: SCHUH (1995) View in CoL : 941 (catalog); KERZHNER & JOSIFOV (1999): 172 (catalog); YASUNAGA (2001): 260 (diagnosis); ZHENG et al. (2004): 560 (diagnosis, key to Chinese spp.).
Diagnosis. Prolygus is distinguished from other similar taxa of the Lygus complex by the following combination of characters: Body elongate oval, small to medium in size (3.0– 4.5 mm); antenna uniformly linear, 0.66–0.75× as long as body; clavus at least basally with two or three rows of keeled lines parallel to claval vein (cf. Figs 1–4 View Figs 1–11 , 12, 16, 18 View Figs 12–23 , 49, 50–52 View Figs 43–53 ); cuneus pale, sometimes median part darkened but not infuscate at apex; male with left paramere L- or C-shaped, with a flat, median projection at apex of hypophysis; right paramere long, not much shorter than left one (its total length usually greater than that of left paramere sensory lobe), with apical part of sensory lobe often inflated; endosoma composed of three lobes, usually with two lobal sclerites (PL and SL); secondary gonopore thick-rimmed, small; phallotheca slender, smooth; female with: sclerotized ring elongate ovoid, thick-rimmed, more or less narrowed medially; posterior wall with spinulate lateral and interramal lobes.
Biology. Little is known about the biology. Specimens of most species were collected using UV light traps. Several Asian species were found on inflorescences of broadleaf trees or shrubs.
Distribution. Known from the Oriental Region and across Wallacea east to New Guinea and several Pacific islands or atolls; at least three species occur in the eastern Palearctic Region (SW Japan and Taiwan).
Discussion. Prolygus was established by CARVALHO (1987) to accommodate sixteen New Guinean species. However, he included many species with irrelevant or questionable affinities which made the generic definition inadequate. Thirteen of the sixteen species (ca. 81%) placed in Prolygus by CARVALHO (1987) have, in our opinion, uncertain generic placements based on their original descriptions or subsequent redescriptions and illustrations: Prolygus albocuneatus Carvalho, 1987 , P. biscutellatus Carvalho, 1987 , P. erimensis ( Poppius, 1914) , P. femoralis ( Poppius, 1914) , P. finisterrensis Carvalho, 1987 , P. kandanus Carvalho, 1987 , P. kebarensis Carvalho, 1987 , P. maai Carvalho, 1987 , P. nakanaiensis Carvalho, 1987 , P. punctialbus Carvalho, 1987 , P. quatei Carvalho, 1987 , P. stali ( Poppius, 1914) , and P. watutensis Carvalho, 1987 . Definitive treatments for these taxa are beyond the scope of our current study. It would require additional material and further investigations of Lygus -complex and related taxa on a world-scale.
Prolygus can now be defined by the characters mentioned in above diagnosis. Based on the possession of these characters, placements of a dozen species in Prolygus are now contradictive. Accordingly, we regard six species as genuine members of Prolygus , but more than a few unidentified congeners are evidently present in the Indo- Pacific Region.
