TAXONOMIC REVISION OF NEARCTIC, MEXICAN, AND WEST INDIAN OODINI (COLEOPTERA: CARABIDAE) YVESBOUSQUET Centre for Land and Biological Resources Research, Agriculture and Agri-Food Canada, Ottawa, Ontario, Canada KIA OC6 Abstract The Canadian Entomologist 128: 443-537 (1996) Eight genera and 25 species are recognized among the Nearctic, Mexican, and West Indian Oodini. Four new species are described: Oodinus pseudopiceus (type locality: Hillsborough River St. Pk., Hillsborough Co., Florida); Oodinus sirnilis (type locality: San Quintin, Chiapas, Mexico); Oodinus darlingtoni (type locality: Cauto El Cristo, Oriente, Cuba); and Oodinus edentulus (type locality: 3 1.8 mi E Francisco Escircega, Campeche, Mexico). Oodes fluvialis LeConte, 1863, previously recognized as a subspecies of 0.arnericanus Dejean, 1826, is given specific status. The following new synonymies are established: Eulachnocrepis Habu, 1956 with Lachnocrepis LeConte, 1853; Stenocrepis texana (LeConte, 1863), S. chalcas Bates, 1882, and S. chalcochrous Chaudoir, 1883 with S. insulana (Jacquelin du Val, 1857); Stenocrepis quatuordecirnstriata (Chaudoir, 1843), S. picipes (LeConte, 1844), S. stenocephala (LaFertC-Sknectkre, 1851), and S. sulcata Chevrolat, 1863 with S. rnexicana (Chevrolat, 1835).Lectotypes are designated for Oodinus alutaceus (Bates, 1882), Oodes arnaroides Dejean, 1831, 0.fluvialis LeConte, 1863, 0. arnericanus Dejean, 1826, Stenocrepis texana (LeConte, 1863), S. chalcas Bates, 1882, S. lecontei (Chaudoir, 1857), S. quatuordecirnstriata (Chaudoir, 1843), S. picipes (LeConte, 1844), S. cuprea (Chaudoir, 1843),S. tibialis (Chevrolat, 1834),S. fernoralis (Chaudoir, 1835),S. elegans (LeConte, 1851), and S. gratiosa (Bates, 1882). The genus-group name Nanodes Habu, 1956, a homonym of Nanodes Schonherr, 1825, is replaced by Nanodiodes, new replacement name. For each genus treated, the following are provided: citation of original description and selected references, notes about synonymy (if required), description, geographical distribution and diversity, and monophyly and phylogenetic relationships. For each species included, the following are given: citation of original description and synonymies, type material, etymology (for new species only), notes about synonymy (if required), diagnosis, description, geographicaldistribution, bionomics, and phylogenetic relationships (if the genus includes more than two species). Keys to genera and, for each genus, to species are included. The species distributions are mapped, and the important structural features are illustrated. Bousquet, Y. 1996.

INTRODUCTION LaFertC-SCnectbre (1851) first used the family-group name Oodites for four genera, Oodes Bonelli, 1810 and three he proposed himself, Lonchosternus, Hoplolenus, and Hololeius. LaFertC-SCnectbre listed the following character states as common to members of Oodites: mentum tooth simple, antennomere 3 not longer than following ones, elytra glabrous, and pronotum nearly always as wide as base of elytra. Hololeius was subsequently transferred to the tribe Chlaeniini (Chaudoir 1856). Other than isolated descriptions of new taxa, little changed in the classification of oodines until Chaudoir (1882-1883) reviewed the world fauna. This work, published posthumously, laid the basis of the present classification of oodines. Chaudoir treated 139 species which he arrayed in 24 genera. Some genera included by Chaudoir within Oodini are today placed in the tribes Dercylini and Melanchitonini. Since Chaudoir's last work, the systematics of oodines has improved mostly through regional studies, such as those of Sloane (1910), Burgeon (1935), Jeanne1 (1949), Basilewsky (1953), Habu (1956), Darlington (1968), Lecordier and Girard (1987, 1988, 1990), or taxonomic revisions of genera, such as those of Basilewsky (1949) and Erwin (1974). The North American fauna has been little studied. Horn (1870) published a revision of the species and subsequently a key to the species (Horn 1881). Blatchley (1910) briefly treated the species found in Indiana. Ball (1960) compiled the information on the genus- group taxa and Lindroth (1969) reviewed the four species found in Canada and one that reaches the northern part of the United States of America. The aim of this publication is to revise the classification of the Nearctic, Mexican, and West Indian species.
