The key description and illustrations of mouthparts, ocelli, and terminal abdominal segments by Bovinq & Craighead (1931) have been the only information on the larval stages of the genus Hemipeplus Latreille, except for the observation by van Emden (1942) that individuals of the genus would not key properly in Boving & Craighead's key. Their example was of an undescribed species from Cuba. The semidiagrammatic illustrations make it difficult to identify the species illustrated, although it may be H. marginipennis (LeConte). This paper is based on larvae collected by the authors, in each case associated with adults. From the family diagnosis of larval Mycteridae (Crowson & Viedma 1964). Hemipeplus larvae differ noticeably in the form of the sensorium, which Crowson & Viedma describe as “very short, dome-shaped”; in Hemipeplus it is elongate and conical. From the larva of Mycterus (described by Crowson & Viedma 1964) those of Hemipeplus also differ in having five ocelli on each side (cf. two), mala with an uncus and medial pit (cf. without uncus or medial pit), mola ridged (cf. not ridged), cardines not divided (cf. distinctly divided, labial palpi with only one distinct palpomere (cf. with two palpomeres), abdominal asperities absent (cf. asperities present), and different form of spiracle (compare fig. 13 with fig. 4 in Crowson & Viedma 1964). Larvae of Hemipeplus are more similar to that of Eurypus muelleri Seldlitz (described by Costa & Vanin 1977) than to that of Mycterus. As in Hemipeplus, Eurypus larvae possess five ocelli arranged in rows of three and two on each side; two pairs of tubercles at posterior margin of abdominal sternite IX; mala with an uncus, and cardines divided. Hemipeplus larvae differ from those of Mycterus most notably in the form of abdominal tergite IX (see Costa & Vanin 1977:fig. 2 ) . The uncus is located on the mesal margin of the mala in Hemipeplus, whereas it is located on the ventral aspect of the mala in Eurypus.
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.
A specimen of Rhizophagus sayi Schaeffer collected in a flight trap at 29°34½'N82°29'W in Alachua County, Florida, on 23-1-1993, by R.W. Lundgren prompted a search of unidentified specimens in the Florida State Collection of Arthropods. The search resulted in the discovery of seven additional Florida specimens with the following data: "FLA., Dixie Co. 3.5mi. N. Old Town 13-1-1980 Coll. M.C. Thomas", 2; "FLORIDA: Alachua Co. Gainesville 3-XII-1983 Coll. M.C. Thomas", 1; "FLORIDA: Alachua Co. San Felasco Hammock 4-11-1983 M.C. Thomasn, 3; same, except date is 12-II-1983. These specimens comprise a new state record for R. sayi, which Bousquet (1990) recorded from most of the eastern United States except for Florida and Georgia.
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."
Neoma, a new genus of Cerambycidae (Coleoptera: Cerambycidae: Prioninae: Macrotomini) is described for Mallodonopsis corrosus Bates, 1879, compared to related genera (Aplagiognathus Thomson, 1861; Archodontes Lameere, 1903; and Mallodonopsis Thomson, 1861), and its tribal position discussed. A lectotype for Mallodonopsis corrosus is here designated with the species redescribed and figured.
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 Mesoamerican species of Telephanus distinguished by the presence eight lateral pronotal spines
and long temples are reviewed. The group includes T. serratus Nevermann and two previously undescribed species
that are described herein: T. bellus Thomas, new species, from Costa Rica, and the flightless T. monstrosus
Thomas, new species, from Mexico.
The Guadeloupe Archipelago, the French overseas Département de Guadeloupe, is a geographically associated group of islands and a natural biogeographic unit. The islands have been available for terrestrial colonization since the late Tertiary. From the viewpoint of beetle systematics and biodiversity, this is the most important set of islands of the Lesser Antilles because more species have been described or recorded from Guadeloupe than any other island or group in the Lesser Antilles. We present a summary of the 1338 beetle species recorded in the literature from the archipelago, in 60 families, and 719 genera. The families with the largest numbers of species are Curculionidae (420), Staphylinidae (153), Chrysomelidae (75), Cerambycidae (69), Scarabaeidae (64), and Tenebrionidae (59). Four hundred eighty two species are known only from one or more islands of the Guadeloupe group and likely speciated there. Guadeloupe is the type locality for an additional 59 species. At least 61 species have been accidentally introduced by human activities. A total of 261 species are known only from the Lesser Antilles including Guadeloupe. The remaining species are naturally more widespread in the Lesser Antilles, or the West Indies, and elsewhere in the New World. The actual number of species on the Guadeloupe Archipelago is estimated to be around 1850 or more species.
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.
Four species of Anchonus Schonherr occur in Florida: A. flol'idanus Schwarz, A. dul'yi Blatchley, A. blatchleyi Sleeper, and A. suillus (Fabricius), which is recorded from Florida and the continental United States for the first time. The species are distinguished in a key and illustrated. A lectotype is selected for A. floridanus.
