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.

New records of eight species of ground beetles (Coleoptera, Carabidae) from Colombia

“…This study adds eight species to the list of Colombian Cara bidae. These species were expected to be found in Colombian territory because previous studies have shown their distribution in nearby countries (Putzeys 1845;Ball 1986;Arndt 1998;Moret and Toledano 2002;Moret 2005;Hoover 2016;Erwin and Henry 2017) (Fig. 3).…”

“…Individuals were collected in various field trips between 1987 and 2019. Identifications were made following the taxonomic keys proposed by Arndt (1998), Martínez (2005), Hoover (2016), Erwin and Henry (2017), and Shpeley et al (2017), and by identification/confirmation by specialists in the family: Terry Erwin (Smithsonian Museum of Natural History, Washington, USA), Danny Shpeley (Strickland Museum, University of Alberta, Edmonton, Canada) and Pierre Moret (Université Toulouse II, France). In addition, some records were confirmed by comparison with high quality images of type material deposited in the Natural History Museum (NHM, London, United Kingdom) and the Museum of Zoology of the University of Sao Paulo (MZUSP, São Paulo, Brazil).…”

Neotropical Thoasia Liebke, 1939 and Straneotia Mateu, 1961 of the Cryptobatida group, subtribe Agrina: Taxonomic revisions with notes on their ways of life (Insecta, Coleoptera, Carabidae, Lebiini)

“…In regard to the genus Hyboptera , with adults having many similar physical attributes as those in Thoasia (Erwin and Henry 2017), recent discoveries of several new Hyboptera species in remote parts of the upper Amazon Basin suggests that further sampling in such areas will also increase the species richness of Thoasia .…”

“…As noted by Erwin and Henry (2017), “Adults of the (currently) monobasic Thoasia Liebke 1939 are exceedingly common in canopy fogging samples (Erwin 1991); however, nothing is known about their way of life and they are only known with precise location from foggings in Perú and Ecuador, and FIT samples in French Guiana. Feeding specializations such as those hypothesized herein for adult Hyboptera and Hybopteroides and commonality of morphological attributes offer a fertile field of study on Thoasia for coleopterists eager to spend long periods of time in the rainforest canopies.”…”

“…Valeriaaschero – Erwin 2004; Hybopteroides – Erwin and Ball 2012; Hyboptera – Erwin and Henry 2017; Aspasiola – Kyana Pike, in prep; Cryptobatis – Charlotte Aldebron, in prep.). Mateu (1961) treated Otoglossa and Pseudotoglossa , but did not have recent canopy samples at the time, thus his work was incomplete from a present day viewpoint; however, his treatment does allow identification of species described up to that time.…”
