A REVISION OF THE ELEODES (SUBGENUS CAVERNELEODES) WITH NEW SPECIES AND NOTES ON CAVE BREEDING ELEODES (TENEBRIONIDAE: AMPHIDORINI)

Abstract. Subgenus Caverneleodes of the genus Eleodes is diagnosed and revised. Six new species from the United States: California (E. microps); Utah and Northern Arizona (E. wynnei), Central Arizona (E. wheeleri), Southern New Mexico (E. guadalupensis), and Mexico (E. thomasi and E. grutus) are described. The biogeography of the subgenus is discussed. Diagnoses and a key are provided to known species of Caverneleodes. Relationships with other Eleodes are discussed. Cave associated Amphidorini are surveyed.

Studies in the Genus Eleodes Eschscholtz with a Revision of the Subgenus Melaneleodes Blaisdell and Omegeleodes, New Subgenus (Coleoptera: Tenebrionidae: Eleodini)

ABSTRACT The taxonomic history of the genus Eleodes Eschscholtz is reviewed and the subgenus Melaneleodes Blaisdell redefined based on characters of the female terminalia with Blaps carbonaria Say herein designated as type-species. Eleodes debilis LeConte is removed from Melaneleodes to a new monotypic subgenus, Omegeleodes, based on the female characters. The subgenus Melaneleodes as redefined contains eleven species: anthracinus Blaisdell (new status), carbonarius (Say), halli Blaisdell (new status), humeralis LeConte, neomexicanus Blaisdell, parowanus Blaisdell, pedinoides LeConte, quadricollis Eschscholtz, rileyi Casey, tricostatus (Say) and wenzeli Blaisdell. Eleodes halli Blaisdell is resurrected from synonymy as the oldest available name to replace the homonym Eleodes fuscipilosus Blaisdell 1925 (nec Casey 1890). Eleodes anthracinus Blaisdell, a subspecies of E. quadricollis Eschscholtz is elevated to full species. The subspecies E. quadricollis lustrans Blaisdell is placed in a new combination as Eleodes anthracinus lustrans. Eleodes speculicollis Blaisdell is reduced to subspecific status as E. wenzeli speculicollis, new combination. Eleodes reductus Blaisdell is reduced to a subspecies giving a new combination, E. rileyi reductus. Eleodes coloradensis Blaisdell, Eleodes concinnus Blaisdell and Eleodes quadricollis lassenica Blaisdell, are all submerged as synonyms under Eleodes rileyi Casey. A key to the species is provided along with diagnoses for each with notes on distribution and variation. Eleodes carbonarius (Say) is redefined to contain a number of variants previously recognized as species or subspecies. Along with the previously recognized subspecies Eleodes carbonarius carbonarius, Eleodes carbonarius omissus LeConte, E. carbonarius knausi Blaisdell, and E. carbonarius soror LeConte, newly recognized subspecific combinations are: E. carbonarius omissoides Blaisdell and E. carbonarius chihuahuaensis Champion. New subspecies described herein are: Eleodes carbonarius nuevoleonensis and E. carbonarius disjunctus. Eleodes mazatzalensis Blaisdell is placed in synonymy under E. carbonarius carbonarius and Eleodes lineatus Blaisdell is placed in synonymy under E. carbonarius chihuahuaensis Champion. A key for the identification of the nine subspecies of Eleodes carbonarius is provided.

A Revision of Eleodes Subgenus Eleodes Eschscholtz (Coleoptera: Tenebrionidae)

ABSTRACT Keys, descriptions and figures are provided for the identification of 30 species assignable to the nominate subgenus of the tenebrionid genus Eleodes. Three species groups can be recognized: the grandicollis group, containing only E. grandicollis Mannerheim; the obscurus group, containing E. obscurus (Say), E. acutus (Say) and E. suturalis (Say); and the dentipes group, containing E. dentipes Eschscholtz, E. acuticaudus LeConte, E. adumbratus Blaisdell, E. armatus (LeConte), E. curvidens Triplehorn & Cifuentes, E. discinctus Blaisdell, E. eschscholtzi Solier, E. femoratus LeConte, E. gracilis LeConte, E. hispilabris (Say), E. loretensis Blaisdell, E. mexicanus Blaisdell, E. mirabilis Triplehorn, E. moestus Blaisdell, E. muricatulus Triplehorn, E. rossi Blaisdell, E. rugosus Perbosc, E. samalayucae Triplehorn, E. sanmartinensus Blaisdell, E. scyropterus Triplehorn, E. spinipes Champion, E. sponsus LeConte, E. subcylindricus Casey, E. tenuipes Casey, E. vanduzeei Blaisdell, and a new species described herein, Eleodes fiski Triplehorn. Eleodes amadeensis Blaisdell and Eleodes striatipennis Blaisdell are synonymized under Eleodes armatus (LeConte). Eleodes subpinguis Blaisdell is synonymized under Eleodes hispilabris (Say). Eleodes wickhami Horn is synonymized under E. eschscholtzi Solier. The status of Eleodes femoratus LeConte 1851 under E. militaris Horn 1870, is reversed based on priority.

A Revision of Eleodes Subgenus Litheleodes Blaisdell (Coleoptera: Tenebrionidae)

Abstract Litheleodes Blaisdell, a subgenus of Eleodes Eschscholtz, is reviewed with diagnoses, distributions, and nomenclatural notes for the nine included species. A type species, Blaps extricata Say, is herein designated, and the subgeneric definition is updated to differentiate it from related subgenera. The species, distributed over the western USA and adjacent parts of Canada and Mexico, are keyed and illustrated.
