Two new species of dioptine moths (Lepidoptera: Noctuoidea: Notodontidae: Dioptinae) are described from the Caribbean island of Hispaniola, and placed in two new monobasic genera. These are the first records of subfamily Dioptinae in the Caribbean Region. Eremonidia mirifica new genus, new species, is a plesiotypic member of the tribe Dioptini, and Caribojosia youngi new genus, new species, is placed in the tribe Josiini. Both species are described from cloud forest habitats in the Sierra de Neiba (Dominican Republic and adjacent Haiti); E. mirifica is also known from similar habitats in the Cordillera Central (Dominican Republic). The larvae of C. youngi are described feeding on mature leaves of Passiflora sexflora Jussieu (Violales: Passifloraceae). Habitats, relationships, ecological associations, behavior, and conservation issues for these species are discussed.

A new species, Camptosaurus aphanoecetes, is named for a partial skeleton of ornithopod dinosaur from the Morrison Formation (Upper Jurassic) of Dinosaur National Monument, Utah. The specimen was originally described as Camptosaurus medius Marsh, 1894, and later referred to Camptosaurus dispar (Marsh, 1879). Comparison of the specimen with a large sample of C. dispar from Quarry 13 shows differences in the proportions and shape of various axial and appendicular elements. Based on the dorsoventrally depressed form of the ilium, Camptosaurus depressus Gilmore, 1909 (Lower Cretaceous of South Dakota) is assigned to the Barremian genus Planicoxa DiCroce and Carpenter, 2001, as Planicoxa depressa, new combination. The well-preserved, undistorted forelimb material of C. aphanoecetes allows for a biomechanical analysis. The range of motion is rather limited throughout the forelimb. The analysis supports the quadrupedal locomotion previously hypothesized for Camptosaurus Marsh, 1885, from limb ratios, fusion of the wrist, and presence of short digits.

This paper presents an analysis of human cranial remains from the Cartago Phase (Period VI, A.D. 1000–1550) in the Central Highlands Region of Costa Rica. The collection was likely obtained by Carl Vilhelm Hartman, Curator of Ethnography and Archaeology at the Carnegie Museum of Natural History, in 1903 during his seven month field expedition to Costa Rica. Aside from the geotemporal context, little is known about the sample, because it was not excavated through systematic archaeology. Bioarchaeology in Costa Rica is restricted due to the poor preservation of biological material because of acidic volcanic soil and high humidity. Large scale looting of archaeological sites has been an unfortunate part of Costa Rican history, and sites have been completely decimated by the hands of looters. This analysis provides information and contributes to the limited corpus of comparative Costa Rican skeletal data that can be utilized for future research.

Ten crania were analyzed for demographic, metric, nonmetric, and pathological conditions. Substantial dental disease was present in the sample. All individuals exhibited periodontitis, and many demonstrated calculus, antemortem tooth loss, abscessing, and carious lesions. Porotic hyperostosis was recorded with varying levels of severity in six of the adult individuals and the juvenile, in whom cribra orbitalia was also noted. Interesting nonmetric traits were identified that demonstrated within-group variation.

The North American flea genus Opisodasys Jordan, 1933 (Siphonaptera: Ceratophyllidae), consists of eight recognized species assigned to three subgenera: Opisodasys Jordan, 1933 (two species); Oxypsylla Smit, 1983 (two species); and Sciuropsylla Dampf, 1942 (four species). Opisodasys (Sciuropsylla) robustus mexicanus Dampf, 1942, is synonymized with the nominate taxon, and Opisodasys (Oxypsylla) keeni nesiotus Augustson, 1941, is elevated to full species status. Keys and brief redescriptions of the subgenera and species are included. Distributions and host preferences for the species are discussed.
