Escalona, H. E. Revision of the neotropical genus <i>Serrotibia</i> Reitter, 1877 (Salpingidae, Coleoptera).

Abstract

The genus Serrotibia Reitter, 1877 is revised, based on adults, larvae, and pupae. The morphology of the genus is studied and its principal characters are described and illustrated. Four species are redescribed: S. cucujiformis Reitter, 1877 from Venezuela (here designed type species), S. unicolor Reitter, 1877 from Peru, S. bicolor Reitter, 1877 from Colombia and S. partita (Olliff, 1883) comb. nov. from Ecuador and Colombia, 14 new species are described: S. pollocki sp. nov. from Guadalupe; S. iviei sp. nov. from Santa Lucia; S. obrieni sp. nov. from Saint Vicent; S. bordoni sp. nov., S. paria sp. nov., S. propinqua sp. nov. and S. indistincta sp. nov. from Venezuela; S. goliathus sp. nov. from Colombia; S. arnaudi sp. nov., S. opitziana sp. nov., S. stanislawi sp. nov. and S. frater sp. nov. from Ecuador; S. lawrenciana sp. nov. from Peru and S. indiscreta sp. nov. from Peru, and Bolivia. S. cucujiformis Reitter was collected on the aroid Philodendron ornatum Schott, 1853 and the palms Wettinia praemorsa (Willdenow, 1804) Wessels, 1988 and Bactris setulosa Karsten, 1857; S. bordoni sp. nov. and S. paria sp. nov. were collected on P. ornatum Schott, 1853. It is feasible to rear these beetles in the laboratory. The most efficent collecting methods are directly on the host plant and with use of lindgren funnel and etanol/metanol traps.
