Hyboptera Chaudoir, 1872 of the Cryptobatida group of subtribe Agrina: A taxonomic revision with notes on their ways of life (Insecta, Coleoptera, Carabidae, Lebiini)

Abstract. Hyboptera Chaudoir, 1872 of the Cryptobatida group of subtribe Agrina, Lebiini, living in the Neotropics and southernmost Nearctic realms are diagnosed, described, and illustrated, and new species are assigned to two inclusive species groups. Occurrences of species range from Texas, USA, to the state of Santa Caterina in Brazil. Seven new species of Hyboptera are described: Hyboptera biolat Erwin & Henry, sp. n.; Type locality – Perú, Madre de Dios, Manu Reserved Zone, Río Manu, BIOLAT Biological Station, Pakitza; Hyboptera vestiverdis Henry & Erwin, sp. n.; Type locality – Perú, Madre de Dios, Manu Reserved Zone, Río Manu, BIOLAT Biological Station, Pakitza; Hyboptera lucida Henry & Erwin, sp. n.; Type locality – French Guiana, Cayenne, Commune de Roura, Montagne des Chevaux; Hyboptera scheelea Erwin & Henry, sp. n.; Type locality – Perú, Loreto, Pacaya-Samiria National Reserve, Río Samiria (South Branch), Camp Terry; Hyboptera shasta Erwin, sp. n.; Type locality – Brazil, Amazonas, north of Manaus on Amazonas 010 at Km 26, Reserva Ducke; Hyboptera tepui Erwin & Henry, sp. n.; Type locality – Venezuela, Amazonas, Cerro de la Neblina, Río Baria Basecamp; Hyboptera tiputini Erwin & Henry, sp. n.; Type locality – Ecuador, Orellana, Yasuni National Park (edge), 95.43 km E (heading 101.46°) Coca, Tiputini Biodiversity Station. A revised identification key is provided to the genera of the Cryptobatida group and another to the species of Hyboptera Chaudoir and distributional data are provided for all known species of the latter. Adults of these species often occur in the canopy of many tropical tree species and records are reported where known. In addition, adults are found under the webbing of Psocoptera and in fleshy anther rings of Bombacaceae (Pseudobombax septenatum (Jacq.) Dugand), on the rain forest floor in the dry season. Larval and pupal stages of one species from Panamá are known from under bark of living fence posts; however, these immature stages are not treated in the current paper.
