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.
Highlights
The Cryptobatida Group of Lebiini was proposed to include a number of genera including Hyboptera Chaudoir (Erwin 2004)
Species names (Erwin and Johnson 2000) with descriptions and provide more complete re-descriptions of known species, so that the group is available for further study, their way of life in association with Psocoptera
One H. auxilidora adult was found by George Vogt in Texas under the webbing of a live colony of Psocoptera, reminiscent of adults of Hyboteroides Erwin & Ball species that live in the colonies of Embioptera (Embiidina) under their webbing (Erwin and Ball 2012)
Summary
The Cryptobatida Group of Lebiini was proposed to include a number of genera including Hyboptera Chaudoir (Erwin 2004). This genus was treated most recently by Reichardt (1971, 1973) and those reports were brief and superficial, not full revisions. Only five isolated species descriptions by Chaudoir, Reiche and Oberthür existed. This small group of very attractive and biologically interesting beetles requires an initial taxonomic revision. We provide full descriptions of all known taxa, including color images, an up-to-date map of their known distributions, and what is known of their ways of life including host tree species
