A review of species of the genera Protapalochrus Erichson and Paratinoides L. Medvedev (Coleoptera, Malachiidae).

The species of the genera Protapalochrus Evers, 1987 and Paratinoides L. Medvedev, 1964 are reviewed. A new subgenus, Protapalochrus (Latapalochrus) Tshernyshev, subgen. n. with type species P. puncticollis (Wittmer, 1970) is proposed. P. arcticus (L. Medvedev, 1958) comb. n. is transferred from Paratinoides L. Medvedev. Two species, Apalochrus chamaeleon Evers, 1971 syn. n. and Troglocollops eversi Iablokoff-Khnzorian, 1988 syn. n. are synonymized under P. puncticollis . The status and position of Apalochrus chamaeleon var. chamaeleonoides Evers, 1971 is discussed. Figures of male external appearance, special structures, genitalia, and distribution map for species are given, and a key to all species of the genus Protapalochrus is provided.
