Pelmatops Enderlein, 1912

Pelmatops Enderlein, 1912: 355 . Type-species: Achias ichneumoneus Westwood, 1850 , by original designation.

Diagnosis. Head of both sexes strongly prolonged laterally, eyes borne at the ends of stalks, the length of which usually is as long as or longer than the abdomen in males or much shorter than the abdomen in females ( Fig. 2, 4 ); antenna shorter than face; arista plumose; chaetotaxy greatly reduced: head with one or two pairs of vertical setae; thorax with only one pair of apical scutellar setae, one pair of scapular and two notopleural setae, postsutural supra-alar, postalar, intra-alar, and anepisternal setae presenr; postpronotal seta present or absent; anatergite covered with fine and long erect microtrichia; wing predominantly hyaline tinged with illdefined pale yellowish-brown markings; cell sc yellow-brown; vein R 4+5 sparsely setose up to slightly beyond level of crossvein R-M, the latter situated well beyond middle of cell dm; 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 tapering and somewhat cylindrical; aculeus more or less rectangular in ventral view, apically tapered to relatively sharp tip and with 4 large, broad serrations on lateral margin. Male terminalia: epandrium large and broad, nearly oval in posterior view; lateral surstylus small and short, apex rounded in lateral view; medial surstylus with 1 black prensiseta.

Pelmatops is very similar to Pseudopelmatops Shiraki in general appearance, especially in having 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 differs by the absence of orbital and genal setae, the eye stalks comparatively long in males, aculeus apically tapered to relatively sharp tip and with 4 large, broad serrations on each side in female.

Three species are known and restricted to the Oriental Region.
