- Two leaf beetles new to Florida (Coleoptera: Chrysomelidae) (1999)
- Specimens recently submitted to the first author for identification turned out to represent two species of leaf beetles previously unknown from Florida, one of which is new to the eastern United States and the other new to the continental United States.
- Description of the larvae of two species of Hemipeplus Latreille (Coleoptera: Mycteridae) (1986)
- 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.
- A revision of the New World species of Cryptolestes Ganglbauer (Coleoptera: Cucujidae: Laemophloeinae) (1988)
- 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.
- Generic key to the known larvae of the Cucujidae, Passandridae, and Silvanidae of America north of Mexico (Coleoptera) (1988)
- Illustrated generic identification keys are presented to the known larvae of cucujidae, Passandridae, and Silvanidae occuring in America north of Mexico.
- Rediscovery of Romulus globosus Knull (Coleoptera: Cerambycidae) (1991)
- 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."
- A new state record for Rhizophagus sayi Schaeffer (Coleoptera: Rhizophagidae) (1992)
- 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.
- An annotated checklist of West Virginia May or June beetles (Coleoptera: Scarabaeidae: Phyllophaga spp.) (1994)
- This first published checklist of West Virginia May or June beetles (Coleoptera: Scarabaeidae: Phyllophaga), lists 29 species. County distributions and the range of collection dates are included.
- Two species of Cerylonidae new to Florida and the U.S. (Coleoptera) (1995)
- In their paper on the Cerylonidae of America north of Mexico, Lawrence and Stephan (1975) noted that Euxestus erithacus Chevrolat is widespread in the Antilles and, although not recorded from Florida, might be found in the southern part of the state. We here report the accuracy of their prediction.
- New revision underway: American beetles : a handbook of the beetles of Nearctic America (1997)
- 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.
- On the genus Anchonus Schönherr in Florida (Coleoptera: Curculionidae) (1999)
- 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.
