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).
