Additions to the known range of Bembidion rufotinctum Chaudoir (Coleoptera: Carabidae: Bembidiini)
(1995)
Previously known from northeastern United States and Virginia, Bembidion rufotinctum Chaudoir is recorded from North Carolina, Tennessee, South Carolina, and Georgia. Habitat preference for this species appears to remain the same throughout its range. Specimens may be found hiding in cracks in rocks exposed to rapidly flowing water. The presence of this species may be indicated by Pentacora ligata (Say)(Hemiptera: Saldidae) that occurs on the same rocks.
Distributional data for the fourteen species of Gerridae known to occur in Argentina are given: Eurygerris fuscinervis (herein first recorded from San Juan and San Luis Provinces), Limnogonus (Limnogonus) aduncus (herein first recorded from Formosa Prov.), L. (L.) ignotus, L. (L.)profugus, L. (Neogerris) lubricus (herein first recorded from Cordoba Prov.), Brachymetra albinerva albinerva (herein first recorded from Salta Prov.), Rheumatobates (Rheumatobates) bonariensis, R. (R.)crassifemur crassifemur (herein first recorded from Santa Fe Prov.), Halobatopsis platensis, H. spiniventris (herein first recorded from Entre Rios Prov.), Metrobates plaumanni plaumanni, M. vigilis, Ovatametra gualeguay (herein first recorded from Buenos Aires Prov.), and Trepobates taylori (herein first recorded from Jujuy Prov.). In addition distributional maps are provided. The species characteristic for each main geographic area of Argentina are: E. fuscineruis and T. taylori for the Northwestern mountainous area; L. ignotus, L. lubricus, and R. crassifemur for the Chacoan plain; L. ignotus and H. platensis for the Bonarian plain; L. ignotus, R. bonariensis, H. platensis and 0 . gualeguay for the Mesopotamian plain. E. fuscinervis and T. taylori are restricted to mountain rivers and rivulets, whereas the remaining species seem to be genuine inhabitants of either rivulets in forested hilly areas (L. aduncus, L. profugus, B. albinerva, H. spiniventris, M. plaumanni and M. vigilis), or rivers, rivulets and ponds in plains (L. ignotus, L. lubricus, R. bonariensis, R. crassifemur, H. platensis, and 0 . gualeguay). L. ignotus is a pioneer species in lowlands, readily colonizing new pools. Excepting L. aduncus, L. profugus, and 0. gualeguay which are rare, the remaining species are common in Argentina (no enough data are available for B. albinerva, M. plaumanni, and M. vigilis). Gregariousness is high in E. fuscinervis, R. bonariensis, R. crassifemur, and H. platensis, and probably also in B. albinerva. The other species mentioned seem not to be gregarious, but 0 . gualeguay appears sometimes in the dense aggregations of H. platensis, suggesting some gregarious tendency.
It is demonstrated that there is no valid basis on which to sustain the monotypic genus Bathycranium Strobl and concluded that Bathycranium should be recognised as a junior synonym of Syntormon Loew (new status). The species Syntormon bicolorellus Zetterstedt (new combination) falls into a natural grouping of Syntormon species with downcurved facial hairs in females. This species and S. luteicornis Parent are redescribed. Distinctions between Syntormonand Parasyntormon are discussed.
First country records for 5 species of Rutelinae are given for Guatemala, as well as new geographical and altitudinal distributions for Plusiotis prototelica Moron & Howden and Plusiotis quiche Morón. Plusiotis auropunctata Ohaus and Chrysina triumphalis Morón are cited from western Guatemala. Plusiotis luteomarginata Ohaus, Plusiotis strasseni Ohaus and Chrysina karschi Nonfried are cited from eastern Guatemala, near the Honduran border.
Calligrapha androwi is newly described from specimens collected in Ohio, Kentucky, West Virginia, and Alabama. It is placed in the subgenus BidensomelaMonros. Acalligrapha Monros and Coreopsomela Monros are reduced to subjective junior synonyms of Bidensomela Monros. A key to the striped species of Calligrapha occurring north of Mexico is adapted from Wilcox (1972) to include the new species.
Fifteen species of Megacyllene occur in Argentina: M. acuta (Germ.), M. bonplandi (Gounelle), M. castanea (Laporte & Gory), M. insignita (Perroud), M. falsa (Chevrolat), M. mellyi (Chevrolat), M. minuta (Chevrolat), M. multiguttata Burmeister (status nov.), . murina Purmeister), M. neblinosa new species, M. proxima (Laporte and Gory), M. spinifera (Newman), M. rotundicollis Zajciw, M. rufipes (Laporte and Gory) and M. unicolor Fuchs (=M. lateripilosa Zajciw new synonym). A Lectotype and Paralectotype are designated for M. multiguttata. Megacyllene quinquefasciata Melzer, 1931, is not considered a true Megacyllene but its generic status remains uncertain and needs further revision. Geographica1 distributions in Argentina and a key are provided.
To date, only two references place members of the genus Diplocentrus in Sonora, Mexico. The first was a passing comment by Francke (1975) that D. spitzeri Stahnke occurs in northeastern Sonora. The specimens he examined and used in his systematic studies on that species are the same as the ones reported here for the first time from a specific Sonoran locality. The second reference was by Sissom and Walker (1992) listing a single record of D. gertschi Sissom and Walker from Libertad on the northern coast. Examination of material from the American Museum of Natural History (AMNH), the California Academy of Sciences (CAS), and the Academy of Natural Sciences (ANS) indicates that, in addition to D. spitzeri and D. gertschi, another distinct species occurs in the Alamos and Navajoa areas in southern Sonora. This species is described as new below. It should be noted that a juvenile specimen from the vicinity of Benjamin Hill was also examined that was unassignable with certainty to any of the above species. This indicates that the genus has a wider distribution in Sonora than demonstrated even by the specimens listed in this report. Nomenclature and mensuration utilized herein essentially follows that of Stahnke (1970), with the following exceptions: carinal terminology and cheliceral measurements are after Francke (1975,1977) and trichobothrial terminology is after Vachon (1974). Specimens in the senior author's collection are listed in the records sections as "WDS”. Because D. spitzeri and the new species are both quite similar to D. peloncil1ensis Francke, the latter is included in the tables for comparison; in addition, the hemispermatophore of this species is also drawn. D. peloncillensis was described from only 6 males, 1 female, and 1 juvenile. The data presented here for D. peloncillensis are derived from these and new specimens available since the original description was published (Francke 1975), thereby providing a better understanding of variation in this species.
A new genus and species of stygobiontic bidessine dytiscid beetle, Comaldessus stygius, from Comal Springs, Texas, is described and compared with the proposed sister epigean genus Uuarus and the only other known stygobiontic bidessine water beetles, Trogloguignotus concii Sanfilippo from Venezuela and Uvarus chappuisi (Peschet) from Africa. Distinctive characters of the adult are illustrated with pen and ink drawings and scanning electron micrographs. The new taxon is the second stygobiontic bidessine genus with rudimentary eyes known from the Western Hemisphere and the first known from North America.
Druciatus nigritarsus new species is described from St. Vincent, Guyana, Ecuador and Peru, D. trisetus new species is described from Ecuador, Brazil and Guyana, D. dissidens and D. latisternus new species are described from Costa Rica, D. angustus new species is described from Mexico, D. campbelli new species is described from Guatemala, and D. petilus new species is described from Ecuador. A key is provided to the eight species in the genus Druciatus.
In one of her latest papers in the American Entomologist, in 1995, Prof. Berenbaum mentions how young people (and entomologists alike) are martyrizing insects and arachnids, by pulling their wings or their legs, burning them with magnifying glasses, without mentioning the lepidopterists who transfix the thorax of the female butterflies to induce them to lay eggs. Such behavior was once one of the acts of the emperor Nero when he was a child. His tutor, the philosopher Seneca, when he saw him pulling the wings off a fly, predicted that he would be very cruel. It was said t h a t the French biologist Etienne Rabaud, well known for his systematic opposition to everything, verified by the scholars of his time, used to cut in half the legs of the daddy longlegs and to declare that those legs were useless because those Arachnids walked better with shorter appendages. Rabaud was also known for removing the swimming bladder of fish to improve, as he said, their balance in water. Such is the tone of this book.
The new genus Sclerocoelus is described for a large group of New World species including Sclerocoelus sordipes (Adams) new combination, Sclerocoelus regularis (Malloch) new combination, Sclerocoelus plumiseta (Duda) new combination, and about 40 undescribed species. The widespread Nearctic species Limosina sordipes Adams is redescribed and designated as the type species of Sclerocoelus. Lectotypes are designated for Limosina sordipes Adams and Limosina evanescens Tucker. The new genus Druciatus is described for a group of 7 undescribed species fiom Central America, South America, and the Caribbean. The type species, Druciatus ovisternus n.sp., is described from Dominica and the Dominican Republic.
Argentinoeme Bruch (1911) remained as a monotypic genus until the finding of the material herein described. The type species of the genus, A. schulzi Bruch (1911) from Argentina, is characterized by 12-segmented antennae, cylindrical pronotum with granulations at its base, femora narrowing only toward their bases, and divided eyes. Argentinoeme pseudobscura sp. nov., with 11-segmented antennae and appendiculate distal segment, constitutes the second known species of this genus.
Occurrence of the milliped Ergodesmus compactus Chamberlin in Canada (Polydesmida: Nearctodesmidae)
(1995)
Recent collecting in southcentral British Columbia, near the International Border, has confirmed the Canadian occurrence of the milliped Ergodesmus compactus Chamberlin, which was predicted by field work in the adjacent part of the United States. With Nearctodesmus insulanus (Chamberlin) occupying the Shuswap Highlands and the Pacific Coastal region, the Nearctodesmidae is known from three separate regions of Canada, all in British Columbia. Other millipeds in the northwestern United States that may be reasonably anticipated in western Canada are discussed.
Diagnostic characters of Glaresis mendica Horn are discussed, and an undescribed species, confused with G. mendica by authors subsequent to Horn, is described as Glaresis gordoni new species. A second new species, Glaresis zvirgzdinsi, is described from two isolated sand dunes in Yuma County, Arizona, USA. Diagnostic characters of the new species, as well as those of G. mendica, are illustrated.

All available material pertaining to Tyrannochthonius Chamberlin from the United States east of the Mississippi River has been examined. The range of the single species already described from this area, T. floridensis Malcolm and Muchmore, is extended. Ten new species are described here; all are troglobites from caves in Alabama.
Seventeen species of Anaphothrips are here recorded and reviewed from the Nearctic Region. Six new species, A. helvolus, A. luteus, A. mexicanus, A. paludicola, A. trimaculatus, and A. univittatus, and 11 nominal species are described. A key to the females of 17 species and to males of 11 species is provided. Anaphothrips flavocastaneus Johansen is reassigned to Oxythrips, A. ripicola Hood is revived as a good species, A. sandersoni Stannard is treated as a junior synonym of A. decolor Hood, and A. sudanensis Trybom is reported from Mexico.
Aphodius alabama, new species, collected in burrows of the southeastern pocket gopher Geomys pinetus Rafinesque, is described. Aphodius dyspistus Skelley & Woodruff, A. hubbelli S. & W., A. platypleurus S. & W., and A. tanytarsus S. & W., collected with A. alubarna, are all recorded from southeastern Alabama.
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.
The known members of the Hydrellia crassipes species group in North America are described or redescribed, including H. crassipes Cresson, H. procteri Cresson, H. saltator Deonier, H. amplecta n.sp., H. bryani n.sp., H. ocalae n.sp., and H. tibiospica n.sp. Adults of these species exhibit the following synapomorphies: dilated male metafemur and expanded (and flange din some) male metatibia and striate (fibrillate) distiphallus. Only a single species (H. tibiospica n.sp.) was reared from its host-plant species, Juncus debilis Gray, but there are associated habitat data to indicate that the entire species group may have sedges andrushes as host plants.
Redescriptions, new synonymy, new North American records (including maps), notes on habitat preferences, and remarks on the status of three Palearctic species of Rugilus in North America are provided. The widespread Palearctic R. orbiculatus (Paykull) is reported for the first time from North America from numerous eastern and western localities. Rugilus latiusculus (Casey, 1884) and R. oregonus (Casey, 1905) are shown to be conspecific with R. orbiculatus (Paykull, 1789) (NEW SYNONYMY); a lectotype for R. 1atiusculus is designated. Rugilus rufipee Gormar, an immigrant species known previously from Washington and Ontario, is newly recorded from Quebec. Rugilus fragilus (Gravenhorst), recorded previously from eastern Canada, is listed for the first time from the United States (Maine and New York).
The species Hydrellia bicarina, n.sp. originally misidentified and described as Hydrellia spinicornis Cresson by Deonier (1971) is redescribed and illustrated. This species was first collectedon and reared from Southern Water Grass Luziola fluitans (Michaux) growing in shallow baytree swamps of southern Mississippi by Deonier (197 1). Based on the male and female genitalia and its natural history, this species is a member of the Hydrellia griseola species group.
Examination of two large collections of Ceratopogonidae from Rondonia, Brazil, and Loreto, Peru, resulted in records of 15 species in the tribes Palpomyiini and Stenoxenini, including three previously undescribed: Bezzia schmitzorum Dippolito & Spinelli, Palpomyia pseudolacustris D. & S., and Stenoxenus aductus D. & S. from Rondonia. The hitherto unknown male of Palpomyia versicolor Macfie is described and figured.
Segun Marcuzzi (1984), hay seis especies de Trientoma en Las Antillas, pero olvidó incluir T. wickhami Casey de Las Bahamas. De esas siete especies, sólo una, se encontraba reportada para Cuba, T. varvasi Solier, 1835. Por lo tanto este género era muy poco conocido y con escasos especímenes depositados en colecciones. Gundlach, en su colección actualmente depositada en el Instituto de Ecología y Sistemática de la Academia de Ciencias de Cuba, posee solamente tres ejemplares. Con el numero 1567 tiene a Trientoma sp., pero en realidad este ejemplar coincide con el género Trimytantron descrito por Ardoin en 1977. Con el 1463 a T. varvasi, y con el 1568 a T. convexipennis.
The subgenus Portmannia Young (1980) of the Neotropical genus Desmopachriais characterized by its ovate, sometimes almost globose body form, smooth shining integument between relatively fine punctures, and sexually dimorphic prostemal process. In the females the prosternal process comes to a point as in other members of Desmopachria, but in males the process is bifid or forked. The species are found from Texas and Arizona to Brazil in South America. They are particularly abundant in Mexico. A key is given for twelve species which are described and figured. The following species are described as new: decorosus (Mexico), goias (Brazil), pittieri (Costa Rica), sobrina (Mexico) and zethus (Mexico). The color is variable. Some species are relatively darkly colored without distinct darker markings, and usually with some coarser punctation on part of the dorsum. These seem to be characteristic of the tropical forests (D. laevis Sharp and D. specula Sharp. D. goias is also dark with vague spots on the elytra). Most of the Mexican and Central American species are characterized by at least parts of the elytra being lighter in color than the head and pronotum, sometimes strikingly contrasting. The latter group may or may not have a distinct dark color patterns of the elytra or on head and pronotum. In both groups some species are intensely dark brown or black beneath, but this character maybe influenced by degree of hardening of the cuticle. Nearly all the species have darker markings along the suture of the elytra and base of the pronotum. Some species are distinctly patterned on the elytra which probably represents disruptive coloration helping to conceal them in the clear, sand-bottomed habitats in which most occur.
Book Review: Identification Guide to the Ant Genera of the World by Barry Bolton Bolton's aim in producing this book was to provide a means of identifying all extant ant genera, and to produce a catalog of existing and fossil genera, as well as the tribes and subfamilies of Formicidae. In accomplishing this goal, he has been thorough, meticulous, and lucid in his revision.
A bibliography is presented on Hydrellia griseola (FallBn), a cosmopolitan species of shore fly that is an agricultural pest throughout much of its range. The literature review includes 195 references and spans 180 years: from 1813, when H. griseola was first described (as Notophila griseola), to 1993. My review updates and extends by 110 years a previous review of this species. The host plant associations, bionomics, distribution, pest status, and control of this species are reviewed. The known host plants of larval H.griseola are listed. My survey of the literature supports the hypothesis that H. griseola is increasing its range as a pest of rice. H. griseola can be controlled by cultural or chemical methods, but due to agronomic and environmental constraints on these methods, my review points out the need for more research on and use of the natural enemies of H. griseola.
Additional descriptive information is given for the genus Ananthidium Urban with a key to species. Also, new geographical and floral records are given. A key to the genera of the Anthidiini of Argentina is provided. Bothranthidium Moure is considered a subgenus of Anthodioctes. A brief discussion of generic characters of the South American genera are given. Carlotica Moure & Urban is placed as a synonym of Epanthidium Moure. Also, Saranthidium Moore & Hurd is considered as a subgenus of Hypanthidiodes Moore.
El género Loxostethus fue descrito por Triplehorn (1962), describiendo las especies fasciatus y opacifrons para Cuba, jamaicensis para Jamaica, y unicolor para Puerto Rico. Todas fueron halladas en hongos, y si bien no han sido reportadas de la Isla de Santo Domingo no es de extrañar que eventualmente aparezcan. Zayas (1989) describió L. quadrimaculata para Trinidad, Cuba-sin embargo, esta última especie cae dentro de la variación individual de L. fasciatus de acuerdo a la descripción de Triplehorn. Por consiguiente, L. quadrimaculata es sinonimizado bajo Loxostethus fasciatus. Gundlach tiene representado en su colección estos dos taxa bajo el género Cyphiscus Chevrolat, nombres que no han sido publicados bajo la familia Tenebrionidae. Se describe una nueva especie, Loxostethus baracoae de Baracoa, Guantánamo. Comparaciones y notas sobre hábitat y distribución de este género son también dados. Un solo individuo colectado enLa Gran Piedra, Santiago de Cuba, aparenta ser una especie aun por describir.
The following new species are described: Lydipta humeralis, sp. n. and Cacostola obliquata, sp. n., from Ecuador; Lochmaeocles leuripennis, sp. n., and Carenesycha velezi, sp. it., from Colombia; Oltcideres marauara, sp. it., from Brazil (Amazonas). Oncideres minuta Thomson, 1865, is recorded from Ecuador.
