Sinoneoneurus He, Chen & van Achterberg 1997: 70 View in CoL . Syn. nov. Type species: Sinoneoneurus obscuripennis He, Chen & van Achterberg View in CoL [= Elasmosoma obscuripennis (He, Chen & van Achterberg, 1997) comb. nov.].

General description. Antenna of ♀ with 13 antennomeres (of ♂ with 14 antennomeres and somewhat longer), shorter than head and mesosoma combined. Head large and transverse. Maxillary palp with 2–3 segments, labial palp with 1–2 segments. Hind tibial spur acute apically. Hind wing without closed cell.

Biology. Attacks adult ant workers, for details see Gómez Durán and van Achterberg (2011). The known hosts are Camponotus castaneus , C. vagus , F. fusca , F. integra , F. obscuripes , F. obscuriventris clivia , F. pratensis , F. rubicunda , F. rufa , F. rufa japonica , F. rufibarbis , F. sanguinea , F. schaufuss , F. subpolita , F. subsericea , Lasius niger , and Polyergus lucidus ( Yu et al., 2016) .

Distribution. Palaearctic, Nearctic and Oriental Regions.

Remarks. The type species of Sinoneoneurus was recently re-examined by C. van Achterberg. The differences between Sinoneoneurus and Elasmosoma as indicated in the key are few, therefore, we include Sinoneoneurus as a subgenus of Elasmosoma .
