Abstract

A new Neotropic genus of Pyxidicerini (Coleoptera: Pselaphidae) ROBERT O. SCHUSTER and ALBERT A. GRIGARICK The pselaphid beetle tribe Pyxidicerini in the neotropics is redefined to include genera with eleven antennomeres and without maxillary fossae. The genera Barroeuplectoides, Tuberoplectus (formerly Euplectini) and Ocabajara n.gen. are placed in the tribe on the basis of sternal, tarsal and abdominal characteristics which are identical to those of Bythinoplectus. Key Words: Pselaphidae, Pyxidicerini, neotropic. R. O. Schuster and A. A. Grigarick, Dept. of Ent., Univ. of California, Davis, California 95616, U.S.A. The tribe Pyxidicerini has been known to both North and South America only by species of the genus Bythinoplectus Reitter, 1881. Bythinoplec- tus is distinguished by nine antennomeres and large fossae for the reception of the maxillary palpi. Other characters consistent for all known species of Bythinoplectus are: 1) Mesosternum (Fig. 2) without an anterior fovea on the midline. 2) Mesosternum with simple anterolateral fovea. 3) Foveae present near both anterolateral and posterolateral margins of mesocoxal cavities. 4) Large basolateral foveae on sternites II, III, IV and V. 5) Lateral margins of tergite IV trans- versely divided (Fig. 4). 6) Two tarsomeres (Fig. 3) (not three as stated by Park 1942
