Polyzosteria cockroaches in Tasmania (Blattodea: Blattidae: Polyzosteriinae) represent a new, endemic species, with allopatric alpine and coastal sub-populations.

We describe the endemic Tasmanian cockroach, Polyzosteria yingina sp. nov. (Henry), 78 years after it was first documented. Evidence from morphology, biogeography and CO1 barcodes is used to distinguish this species from related mainland Australian taxa it has previously been confused with. Polyzosteria yingina sp. nov. has two strongly allopatric populations: a compact alpine population above 1000m and a dispersed east coastal one at sealevel. However, mitochondrial Control Region D-loop molecular analysis suggests a single species identity for these disparate populations. Detailed internal and external morphological descriptions and photographs of living and preserved type material are presented. We also speculate on some hypotheses which could account for the unusual distribution of this charismatic insect.

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

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.

Resumen Hyboptera Chaudoir, 1872, del grupo Cryptobatida, perteneciente a la subtribu , Lebiini, viviendo en los Neotrópicos y en las áreas meridionales del Neártico se diagnostican, describen e ilustran y nuevas especies se asignan a dos grupo-especies inclusivos. La distribución de las especies recorre desde Texas, EE.UU., hasta el estado de Santa Caterina en Brasil. Siete nuevas especies de Hyboptera se describen: 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. Se provee una clave revisada para los géneros dentro del grupo Cryptobatida y otra para las especies del género Hyboptera Chaudoir y se incluye información sobre la distribución de todas las especies conocidas de éste último. Los adultos de estos comúnmente se encuentran en el dosel de muchas especies de árboles tropicales y registros se reportan cuando se conocen. Además, los adultos pueden estar debajo de las telas de sócidos y en los anteridios carnosos de los Bombacaceae (Pseudobombax septenatum (Jacq.) Dugand) en el suelo del bosque lluvioso. Las etapas de larva y pupa de una de las especies de Panamá se conocen viviendo debajo de la corteza de postes vivos de cercas; sin embargo, estos so se tratan en este artículo.
