A new species of Tithorea, Tithorea pacifica n. sp., is described and diagnosed from pluvial premontane rain-forest in northwestern Ecuador. Two additional new subspecies, T. pacifica euphonia n. ssp. and T. pacifica concordia n. ssp., are also described, from western Colombia and extreme eastern Panama, respectively. Adult specimens and genitalia of both sexes are illustrated for the three known species of Tithorea and the characters that distinguish the species are tabulated.

Five new species of Cerambycidae from Puerto Rico, Antilleptostylus guilartensis, Leptostylopsis guanica, Leptostylopsis yukiyu, Leptostylopsis monin, and Urgleptes borikensis are described. A new combination, Antilleptostylus brunneofasciatus (Fisher), and new synonymy, Leptostylopsis oakleyi (Fisher) = Leptostylopsis gundlachi (Fisher) are also proposed. Habitus figures of the new species, keys for separating the Puerto Rican species of Leptostylopsis Dillon and Urgleptes Dillon, a key and figures for separating the species of Antilleptostylus Gilmour, a figure to help in separating Leptostylopsis gundlachi Fisher and two new related species, and a figure of some typical elytral color pattern variations in Urgleptes borikensis are presented.

An intensive survey for Cerambycidae of El Yunque National Forest and many of the state forests in Puerto Rico showed 49 species representing over half of the hitherto reported species from the Island. Two tribes and four genera are recorded from Puerto Rico for the first time. The description of a new genus, Pseudothonalmus Guerrero, is included. Four new species are described: Elateropsis julio Lingafelter and Micheli, Pseudothonalmus woodleyi Lingafelter, Micheli, and Guerrero, Styloleptus taino Lingafelter and Micheli, and Distenia puertoricensis Lingafelter and Micheli. The larva of Parandra tavakiliani is described. Locality data and method of collection are provided for all encountered Cerambycidae.

Six new species of Leptoglossus Guérin from Brazil, Costa Rica, México, Peru, and Venezuela are described. Diagnostic taxonomic characters of antennal segments, legs, male genital capsules, and dorsal views of some species are illustrated. Most of the species are placed in their corresponding species-group, as well as the previous incertae-sedis species.

Eleven species of Heteroptera in seven families, including the first record of the family Alydidae, are reported from the Galápagos Islands. The first Galápagos Island records are given for the following: Alydidae [Neomegalotomus parvus (Westwood)]; Coreidae [Vazuezitocoris andinus Brailovsky = Anasa mimetica Brailovsky]; Miridae [Halticus bractatus (Say)]; Pentatomidae [Mecidea minor Ruckes, Nezara viridula (Linnaeus), Piezodorus guildinii (Westwood), and Podisus distinctus Stål]; Reduviidae [Heza ephippium (Lichtenstein)]; Rhopalidae [Niesthrea ashlocki Froeschner, Niesthrea sidae (Fabricius)]; and Tingidae [Leptobyrsa decora Drake]. For each species, we give a diagnosis, dorsal photograph, a summary of the distribution and host plants, and provide information to facilitate identification. With the discovery of these new taxa and the correction of several misidentifications, the number of Heteroptera known from the Galápagos Islands is increased from 20 families, 71 genera, and 131 species to 21 families, 76 genera, and 140 species.

Twenty individuals diagnosed with delusory parasitosis participated in a single site clinical study under the auspices of the National Pediculosis Association (NPA) and the Oklahoma State Department of Health. The objective of this study was to determine if there were any common factors in skin scrapings collected from this population. These individuals, whose symptoms were originally attributed to lice or scabies, were part of a larger group reporting symptoms of stinging/biting and/or crawling to the NPA. Multiple skin scrapings from each person were microscopically examined. Any and all fields of view that appeared incongruous to normal human skin were digitally photographed. When the photographic images were initially evaluated, no common factor was identified. However, more extensive scrutiny using imaging software revealed evidence of Collembola in 18 of the 20 participants.
