- The genus Cotinis Burmeister in the eastern United States,with description of a new species from the Florida Keys, including a checklist of the genus (Coleoptera: Scarabaeidae: Cetoniinae) (2008)
- In the eastern United States, the genus Cotinis Burmeister previously contained only C. nitida (L.), the common economic pest known as the "Green June Beetle". A new species from the Florida Keys, Cotinis aliena, is here described and illustrated. A checklist is provided for the genus, which includes 27 valid New World species, and 44 synonyms.
- A new fossil species of stag beetle from Dominican Republic amber, with Australasian connections (Coleoptera: Lucanidae) (2009)
- The first New World amber member of the family Lucanidae is described from the Dominican Republic. Its age is presumed to be Miocene (20-30 million YBP). It is also the fourth known amber species, the second Miocene fossil species, the second fossil species in the subfamily Syndesinae, and the first species (fossil or extant) of Lucanidae from the entire Caribbean. It is especially interesting because it is a member of the Australasian genus Syndesus MacLeay. Other such disjunct Dominican amber insect fossils are also discussed.
- 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.
- Life or death in amber? (1994)
- Because I've studied Dominican Amber for 25 years, this article began as a simple request for me to review a recent book: "Life in Amber" by George 0. Poinar, Jr., Stanford university Press. 350p.; 37 color and 154 black and white photos; 8 maps. Publication date: Sept. 25, 1992. Price: $55.00. It was soon obvious that the volume and nature of my comments precluded a simple review. My paraphrased title is a minor semantic difference with Dr. Poinar's, although I doubt that he would write of "Life in Egyptian Tombs". Creatures preserved for 30 to 40 million years should at least be "Former Life in Amber". So much for trivia.
- A new species of Phyllophaga Harris from the island of Navassa in the Caribbean (Coleoptera: Scarabaeidae: Melolonthinae) (2011)
- The small Caribbean island of Navassa (U.S. possession) is unoccupied by humans, but recent surveys have detected a surprising number of endemic (precinctive) invertebrates. A new species of May beetle, Phyllophaga navassa, is here described and compared to the Hispaniolan Phyllophaga fauna.
- Corrigenda to and validation of Ozophora woodruffi Slater 2005 (Hemiptera: Lygaeidae) (2012)
- Important missing specimen data are provided for the original description of Ozophora woodruffi Slater (2005: 245) (Hemiptera: Lygaeidae), along with additional comparative relationships. Because of the missing type information, according to ICZN rules (1999), the species became a nomen nudum. This paper now serves to validate the name, and authorship becomes Slater (2012).
- New Species of Phyllophaga Harris (Coleoptera: Scarabaeidae: Melolonthinae) from northeastern Mexico (2014)
- Three new species of Phyllophaga are described from northeastern Mexico: P. (s.str.) gramma n. sp. from grasslands near Monterrey city, state of Nuevo Leon; P. (s.str.) jeanmathieui n. sp. from mixed forests of Sierra Chipinque, Nuevo Leon; and P. (Listrochelus) pinophilus n. sp. from pine-oak forests of mountains in Nuevo Leon and Coahuila. Illustrations of diagnostic structures and comments about the relations of each species are provided.
- A new species of the beetle genus Brachypsectra from the Dominican Republic : with fossil connections (Coleoptera: Brachypsectridae) (2002)
- With the description of Brachypsectra uiuafosile n. sp., from the Cabo Rojo desert area of Hispaniola, the beetle family Brachypsectridae now contains 4 described species. The family was originally known from the Dominican Republic by Miocene amber fossils oflarvae. Genitalia are illustrated for the first time for the family. Relationships of the family within the Elateroidea are briefly discussed.
- Revision of the Phyllophaga of Hispaniola (Coleoptera: Scarabaeidae: Melolonthinae) (2004)
- With this study, the fauna of Hispaniolan Phyllophaga is now composed of 48 species, all of which are endemic (precinctive), including 22 new species described herein (4 attributed to Woodruff and Sanderson: approxima, bonfils, jimenezi, rex; 18 to Woodruff: aceitillar, alcoa, androw, baoruco, carnegie, davidsoni, eladio, haitiensis, jaragua, larimar, marcano, nunezi, ortizi, pedernales, rawlinsi, rustica, santachloe, toni). Additionally, allotypes are described for 7 species with previously unknown males (aliada, canoa) or females (esquinada, fossoria, imprima, kenscoffi, panicula), and 6 new country records (Dominican Republic) are provided (aliada, leptospica, minutissima, panicula, permagna, recorta). Of the 48, only 1 male remains unknown (barrosa), and 9 females are missing (aceitillar, carnegie, costura, davidsoni, espina, garrota, probaporra, rustica, toni); 32 are recorded only from the Dominican Republic, and 5 are known only from Haiti. The 727 Figures include 50 habitus illustrations for all species, as well as SEM photos of male and female genitalia, and other salient morphological characters. The discovery of “sister species”, on opposite sides of the Enriquillo basin, provides significant data to support the 2 island concept; 15 species are known only from the paleo “south island”, and 23 are restricted to the “north island”.
