Pseudopelmatops Shiraki

Pseudopelmatops Shiraki, 1933: 49 . Type-species: P. nigricostalis Shiraki, 1933 , by original designation.

Diagnosis. This is another distinctive genus of Tephritidae characterized by the head of both sexes prolonged laterally, eyes borne at the ends of stalks, the eye stalk in the male shorter than the abdomen ( Fig.6 , 8,9); antenna almost equal to face or longer than face; arista plumose; chaetotaxy reduced: head with orbital, medial vertical and genal setae present, frontal setae present or absent; thorax with 1 notopleural, 1 postalar and 1 apical scutellar setae present; anatergite covered with fine erect setulae; wing predominantly hyaline; cell sc yellow-brown; vein R 4+5 bare or setose; legs slender and long, femora lacking setae or spines ventrally; abdomen elongate, syntergite 1+2 nearly parallel-sided. Metathoracic postcoxal bridge broadly sclerotised. Female terminalia: oviscape yellow-brown, tapering and somewhat cylindrical, aculeus more or less rectangular in ventral view, with a small and round apex, apicolaterally not serrated. Male terminalia: epandrium large and broad, rounded in posterior view; lateral surstylus small and short, apex rounded in lateral view; medial surstylus with 1 black prensiseta.

Pseudopelmatops is closely related to Pelmatops Enderlein in the head being strongly prolonged laterally, eyes borne at the ends of stalks; chaetotaxy of head and thorax reduced; femora lacking setae or spines ventrally; and abdomen long and slender, syntergite 1+2 almost parallel-sided, about equal in length to tergites 3–5. It can be recognized by the presence of orbital setae; the eye stalk in the male distinctly shorter than the abdomen; palpus narrow, parallel-sided and densely covered with strong, black setulae (except for Ps. indiaensis Chen sp. nov.).

Five species are known and restricted to the Oriental Region.
