New synonymies and lectotype designations in the Neotropical tribes Nycteliini, Praocini, and Scotobiini (Coleoptera: Tenebrionidae)

Seven new synonymies within the genus Praocis Eschscholtz, 1829 (Praocini) are proposed: P. audouini Solier, 1840 with P. sanguinolenta Gay & Solier, 1840; P. rufitarsis Gay & Solier, 1840 with P. tibialis Gay & Solier, 1840; P. submetallica Guérin-Méneville, 1834 with P. subaenea Erichson, 1834; P. chevrolati coquimboana Kaszab, 1969 with P. chevrolati subcostata Gay & Solier, 1840; P. convexa Germain, 1855 with P. pleuroptera Gay & Solier, 1840; P. denseciliata Fairmaire, 1883 with P. striolicollis Fairmaire, 1883; and P. compacta Fairmaire, 1883 with P. inermis Burmeister, 1875. Two new synonymies within the genus Nyctelia Latreille, 1825 (Nycteliini) are proposed: N. planicauda Fairmaire, 1905 with N. laticauda Burmeister, 1877 and N. bifoveata Fairmaire, 1905 with N. vageimpressa Fairmaire, 1904. Praocis elliptica Philippi & Philippi, 1864 stat. rev., placed prior to this study as a synonym of P. submetallica, is reinstated as a valid name. Praocis concinna Burmeister, 1875 is rediscovered and assigned to the subgenus Postpraocis Kulzer. Lectotypes are designated for 66 nominal species of the Neotropical tribes Nycteliini, Praocini, and Scotobiini (Coleoptera: Tenebrionidae), including all the species treated in the synonymies.Fil: Flores, Gustavo Ernesto.
