A new species, Chrysobothris cerceripraeda Westcott and Thomas (Coleoptera: Buprestidae), is described from prey specimens found in nests of the ground-nesting wasp, Cerceris fumipennis Say (Hymenoptera: Crabronidae), near Jacksonville, Florida, USA. A listing for all species of Buprestidae taken as prey of the wasp in that state is provided, four of which, including the species described herein, are new. Notes are also given for
four new state records for Buprestidae.
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.
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.
Australophanus, new genus, is described and illustrated for Cryptamorpha redtenbacheri (Reitter). Platamus Erichson is synonymized under Telephanus Erichson, new synonymy. Euplatamus Sharp, new status, replaces Platamus Erichson as the genus name. Type species are designated for Aplatamus Grouvelle and Euplatamus Sharp. Telephanus velox (Haldeman) is synonymized under Telephanus atricapillus Erichson. A diagnosis of the tribe Telephanini, a key to the described telephanine genera of the world is presented, and a phylogeny of the family Silvanidae is proposed.
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.
