Chrysis chrysofacialis Linsenmaier, 1984 , Chr. scyphiphora Linsenmaier, 1984 and Chr. turmalina Linsenmaier, 1984 were synonymized by Kimsey & Bohart (1991) with Caenochrysis parvula ( Fabricius, 1804) based on Linsenmaier’s descriptions.Of these, only Cae. chrysofacialis is apparently a synonym of Cae. parvula , although one of the key diagnostic characters, the arched transverse frontal carina, cannot be verified as the head of the holotype of Cae. chrysofacialis is lost; however, further examination of paratypes may prove definitive. Meanwhile, based on morphological comparison of the types of Cae. chrysofacialis and Cae. parvula , we consider these two taxa as conspecific. Linsenmaier (1984) also accepted the synonymization of Cae. parvula with Cae. tridens Lepeletier de Saint-Fargeau & Audinet-Serville, 1825 proposed by Mocsáry (1889), although he considered it doubtful because of the different sizes of these two species; they were later considered as two valid species by Kimsey & Bohart (1991).
