The issid planthopper genus Acanalonia is reviewed and a key to the 18 species provided. Detailed descriptions and illustrations of the complete external morphology of A. conica (Say), and descriptions and illustrations of the male and female external genitalia of the species of united States Acanalonia are given. The principal genitalic features used to separate species included: male-shape and length of the aedeagal caudal and lateral processes, and presence of caudal extensions; female -shape of the 8th abdominal segment and the number of teeth on the gonapophysis of the 8th segment.
Two new species of the genus Euxesta Loew are described and illustrated: E. pacifica from California and E. atlantica from Florida, in the Quaternaria subgroup of the Notata group. A key is presented to the two new species, as well as E. calligyna (Bigot 1857), E. quaternaria Loew (1868), E. luteocesta Foote (1960), and E. nigricans Wulp (1903) of the quaternaria subgroup.
The dictyopharid planthopper genus Phylloscelis is reviewed and a key to the four species provided. The morphology ofadult male and female P. pallescens Germar, P. atra Germar, P. rubra Ball, and P. pennata Ball is described and illustrated in detail. The species are separated principally by color patterns, wing venation, and features of the male and female external genitalia.
Recent collections have resulted in provisional extensions of distributional ranges of 4 species of Bruchidae. All species of plants listed belong to the Leguminosae (Fabaceae). Acanthoscelides obvelatus Bridwell was recently intercepted at the Miami, Florida, International Airport infesting Phaseolus spp. beans grown in Haiti and Cuba. Previous records for this bruchid include mainland localities in Mexico, Guatemala, and Colombia. No precise localities in the West Indies are known. These collections indicate that this bruchid is probably established on Hispaniola and Cuba.
Examination of a large collection of Ceratopogonidae from Rondonia, Brazil, resulted in records of 11 species in the tribes Heteromyiini and Sphaeromiini, including the NEW GENUS Groganhelea Spinelli & Dippolito NEWGENUS, which is described herein, with its type-species G. rondoniensis Spinelli & Dippolito, NEW SPECIES. Heteromyia correntina Lane & Duret and Mallochohelea termophila (Spinelli) are recorded for the first time from Brazil.
Book Review: Of all of the Florida invertebrates that exist, or may have existed (one estimate claims 50,000 species) only descriptions of 350 species are included in this book. These are species that are thought to be, according to the many individual authors who wrote the accounts of these species, in decline or in danger of extinction. Final acceptance to be included in this book, and others in the series, is made by the Florida Committee on Rare and Endangered Plants and Animals. They believe, as do the various authors and editors, that there is enough information available to show that these species need special attention.
Two new species of Kermesidae, Kermes orientalis Liu and Shi and K. flavus Liu, are designated. Morphological characters of post-reproductive and teneral young adult females, as well as the first instars (crawlers) are described and illustrated. A key to the young adult females of the genus from China is given. Type materials are deposited in the Insect Collection, Section of Entomology, Department of Entomology, Shandong Agricultural University, Shandong; Insect Collection, Institute of zoology, Chinese Academy of sciences, Beijing, China; and British Museum (Natural History), London, England.
The species of Tirnarcha are unique living fossils among the leaf beetles. They walk very slowly, cannot escape by flight, and their majestic bearing can be compared to the Athenian judges, the Timarches. Unfortunately, they are vulnerable to habitat disturbance, insecticides, and environmental changes. Some of the European such as Timarcha tenebricosa and T. goettingensis are becoming more and more rare because of these same habitat changes.
Ten new species of Tetraleurodes (bireflexa, caulicola, chiuela, confusa, dorsirugosa, mexicana, perseae, pseudacaciae, quercicola, tuberculosa) are described and four previously known species are redescribed. The acaciae group consisting of seven species is proposed, and a key to the acaciae group and 12 North American species is provided. In addition, herberti Penny is synonymized with acaciae (Quaintance), nudus Sampson and Drews is synonymized with fici Quaintance and Baker, and stanfordi (Bemis) is synonymized with perileuca (Cockerell). Aleurotrachelus cacaorum Bondar is reassigned to Tetraleurodes, and T. papilliferus Sampson and Drews is reassigned to Aleurotrachelus.
