Type species (by original designation): Neopius carinaticeps Gahan, 1917 (= Opius rudis Wesmael, 1835 ). Diagnosis. Occipital carina complete dorsally and crenulate in dorsal and lateral view; frons distinctly granulate; mandible normal, gradually widened basally; hypoclypeal depression variable; anterior margin of pronotum sculptured, notauli elongated at least until half of mesoscutum; medio-posterior depression of mesoscutum present; precoxal sulcus sculptured; propodeum densely sculptured; vein 3-SR of fore wing distinctly longer than vein 2-SR, vein m-cu of fore wing postfurcal, second submarginal cell narrowing outwards, CU1b short and apically absent, first subdiscal cell open; first tergite as long as apical width, second tergite as long as third tergite and sparsely granulate-punctate, ovipositor sheath short. Biology. Parasitoids of Agromyzidae , including species Agromyza megalopsis Hering 1933 and Agromyza nigripes Meigen, 1830 . Comments. Neopius Gahan was considered a synonym of the genus Euopius Fischer, 1967 ( Fischer, 1967 ) . Later, Fischer (1972) included Neopius Gahan as a synonym of the former subgenus Xynobius Foerster, 1863 in Opius Wesmael, 1835 . In 2005, this genus was proposed as a subgenus of the genus Xynobius ( Papp, 2005 ) . Quicke et al. (1997) included Neopius as a subgenus in Phaedrotoma Foerster, 1863 because its venom apparatus is very similar to those of other Phaedrotoma species examined, and it has no apomorphies in common with Xynobius or Opius s.s. However, Neopius differs from other subgenera of Phaedrotoma in having a medio-dorsally complete occipital carina and granulate frons, and the molecular data presented in Li et al. (2013) indicated that Neopius is not closely related to Phaedrotoma , so it is treated here as an independent genus of Opiinae with its own apomorphies (occipital carina secondarily complete dorsally and frons distinctly granulate).
