Several Coleopterists have been asked to revise the family sections, working from diskettes modified and provided from the original "Beetles of the United States." They will rewrite these sections, and will be recognized as the author of the section. They are asked to sign a writing contract with the publisher. Other Coleopterists have been asked to review the family sections of the new book. These persons are acknowledged in the family section text.
The New World species of Cryptolestes Ganglbauer are revised and keys, diagnoses, descriptions, and illustrations are provided for the 13 non-economic species. Six stored products species of the genus are also keyed and illustrated. Two species, Laemophloeus pubescens Casey and L. bicolor Chevrolat, are reassigned to Cryptolestes. Eight new species are described: C. dissimulatus (southwestern United States); C. dybasi (Florida); C. mexicanus (Mexico and Guatemala); C. capillulus (Brazil); C. spatulifer (Argentina); C. trinidadensis (Trinidad); C. ampiyacus (Peru); and C. calabozus (Venezuela). Cryptolestes uncicornis (Reitter) is revived from synonymy under C. punctatus (LeConte), C. schwarzi (Casey) is revived from synonymy under C. weisei (Reitter), and four specific names are synonymized: C. quadratus (Casey) [ = C. uncicornis (Reitter)]; C. extricatus (Casey) and C. adumbratus Casey [ = C. punctatus (LeConte)]; and Laemophloeus concavus (Reitter) [ = C. bicolor (Chevrolat)]. Cyptolestes horni (Casey) and C. disseptus Casey are removed from Cryptolestes and reassigned to Rhabdophloeus Sharp. Lectotypes are designated for Laemophloeus geminatus LeConte, Cryptolestes adumbratus Casey, and Laemophloeus quadratus Casey.
One of the rarest U.S. cerambycids, Romulus globosus, was described by Knull in 1948 based on four specimens collected in peninsular Florida. No new records have been reported in the literature since. Linsley (1963) apparently saw no specimens, since he merely quoted the original description, and gave the distribution as "Southern Florida."
The genus Pediacus Shuckard is revised for America north of Mexico. Seven species are recorded: P. andrewsi Thomas, n. sp.; P. fuscus Erichson; P. gracilis Thomas, n. sp.; P. hesperoglaber Thomas, n. sp.; P. ommatodon Thomas, n. sp.; P. stephani Thomas, n. sp.; and P. subglaber LeConte, new status. The species are described and illustrated, and a key is presented for their identification. The described European and Neotropical species are reviewed and illustrated.
The following new species of Cryptolestes Ganglbauer are described and illustrated: Cryptolestes obesus Thomas, new species, Brazil; Cryptolestes turnbowi Thomas, new species, Honduras and Mexico; Cryptolestes inyoensis Thomas, new species, California; Cryptolestes spectabilis Thomas, new species, Ecuador. A revised key to the New World species is provided. The male genitalia are illustrated and the female of C. calabozus Thomas is characterized, and new distribution records are provided for it, C. cornutus Thomas and Zimmerman, C. trinidadensis Thomas, C. curus Lefkovitch, and C. hlapperichi Lefkovitch.
