This study evaluates the conservation status of all of the United States species and subspecies of tiger beetles on the basis of the published literature, unpublished reports, museum and private collections, our personal field work and contact with collectors. We provide a brief summary of the status of the four species already listed and the two candidates for listing by the U. S. Fish and Wildlife Service. We indicate three taxa believed to be extinct and evaluate 62 others that we deem sufficiently rare to be considered for listing as endangered or threatened. We used a 1, 2, 3 grading system that is generally comparable to the terminology of critically imperiled, imperiled, and vulnerable designations, respectively, used in NatureServe Explorer. Fifty-two of these taxa are from the western states and Texas and most of them are named subspecies with extremely limited distributions and habitats. We assigned seven taxa a 1+ grade, our highest level of rarity and/or threats; of these there is presently sufficient information available to consider two of them-- Cicindelidia floridana Cartwright and Cicindela tranquebarica joaquinensis Knisley and Haines-- as the U. S. forms most in danger of extinction. Future prospects for conservation and listing of tiger beetles seem bleak because of the limited budget and personnel available for Endangered Species in the U. S. Fish and Wildlife Service and the current economic and political climate in the United States.

Results of taxonomic revision of Mexican and Central American species of the genus Odontocheila Laporte de Castelnau, 1834, related to Odontocheila mexicana Laporte de Castelnau, 1834 (rectified publication date) and O. ignita Chaudoir, 1860 are presented. Redescriptions of O. mexicana, O. iodopleura Bates, 1872 and O. exilis Bates, 1884 are provided with their lectotype designations, and redescriptions of O. tawahka Johnson, 1996 and O. ignita are presented. O. exilis is restored to its original species status. Lectotype designations of O. cinctula Bates, 1881 and O. quadrina (based on Cicindela quadrina Chevrolat, 1835) are provided. The synonymy of O. cinctula with O. ignita is confirmed, as well as the synonymy of O. quadrina with O. mexicana. O. potosiana sp. nov. is described from Mexico as new for science; it represents the northernmost occurrence of the genus. A key to these related species is presented and their biology and distribution is treated. Illustrations in colour photographs of the habitus, diagnostic characters and variability are provided.

A new species of the Madagascan endemic genus Physodeutera Lacordaire, 1842 is described from northern Madagascar as Physodeutera (Microlepidia) propripenis sp. nov. The new species is compared to similar Physodeutera (Microlepidia) marginemaculata (W. Horn, 1934) and Physodeutera (Microlepidia) peyrierasi Rivalier, 1967. Apart from a detailed description of the new species, illustrations in colour photographs of its habitus, diagnostic characters and habitat are introduced. Differential diagnoses of the two similar species, as well as illustrations of their habitus and distinguishing characters in colour photographs are presented with references to their redescriptions and illustrations based on type and other relevant specimens in the monograph of the genus (Moravec 2002a). A revised key to the subgenus Microlepidia Rivalier, 1967 is presented in order to supplement the key previously published in the monograph. Essential maps of the distribution of the three species are also given.

Taxonomic and nomenclatorial revision within the Neotropical genera of the subtribeOdontochilina W. Horn in a new sense -11. The genus Cenothyla Rivalier, 1969 (Coleoptera: Cicindelidae)Jiří MORAVEC Sadová 336/21, Abstract. Results of a taxonomic and nomenclatorial revision of the genus Cenothyla Rivalier, 1969 with type species Cicindela consobrina Lucas, 1857 is presented with a brief history and lectotype designations in relevant taxa. The revision has confirmed that Cenothyla is clearly a delimited genus separated from the related genus Odontocheila Laporte de Castelnau, 1834 by the shape of the aedeagus, namely by the characteristic structure of the internal sac which in Cenothyla lacks any trace of a flagellum, and contains unique sclerites.

A new replacement name Odontocheila microptera nom. nov. for Odontocheila euryoides W. Horn, 1922 that is a junior primary homonym of Odontocheila bennigseni euryoides W. Horn, 1906 (currently Euryarthron bennigseni euryoides), is introduced. It has been confirmed that O. microptera, due to its atrophic thoracic wings, is the only flightless species of the genus and of the whole subtribe Odontocheilina W. Horn, 1899 sensu Moravec (2012). Redescription and illustrations of the habitus, diagnostic characters and biotope of this hitherto little know species, as well as of the similar O. nitidicollis (Dejean, 1825), along with the lectotype designation of the latter, are presented. Distributions and habitat of both species are treated and discussed.
