La mayoria de las especies de "guaguas" bland as presentes en Cuba han sido estudiadas por su relacion con las plantas de interes economico, sin embargo, en los sistemas naturales la fauna de estos insectos es casi desconocida. En este trabajo se dan a conocer tres nuevos registros de coccidos para Cuba, recolectados en ecosistemas naturales, los cuales corresponden a Coccus capparidis (Green, 1904), Saissetia miranda (Cockerell & Parrot, 1899) y Toumeyella liriodendri (Gmelin, 1790), y se relacionan sus plantas hospedantes con nuevos registros para estas especies.
Taxonomy, phylogeny, and biogeography of the genus Asydates Casey (Insecta: Coleoptera: Melyridae)
(2001)
The genus Asydates Casey (Coleoptera: Melyridae) is revised, containing three species from Arizona and California: A. explanatus Casey; A. inyoensis (Blaisdell), new combination; and A. rufiuentris Casey. The monotypic genus Pseudasydates Blaisdell is placed in synonymy with Asydates Casey, syn. nov., and Asydates puncticeps Blaisdell is placed in synonymy with Asydates explanatus Casey, syn. nov. A key separating adults of Asydates species is provided, and the results of a computerized cladistic analysis of Asydates species are presented. GIS mapping of Asydates species distributions indicates that these species are nearly allopatric, with A. explanatus found in the lower Colorado River basin and adjacent deserts, A. inyoensis restricted to the Inyo and White Mountains, and A. rufiuentris found in the coastal plain and coastal mountains near Santa Barbara. Geographic hypotheses of character evolution within Asydates are developed by combining the results of cladistic analysis and GIS mapping.
Information on the immature stages of Australasian Tabanidae found in published literature dealt with only 17 species, all so far known only from Australia and none representing the genus Chrysops Meigen. Two of the four Australasian species of Chrysops are found on the island of New Guinea, and both, C. albicinctus Wulp and C. australis Ricardo, are described and illustrated.
The cholevine beetles inhabiting burrows of Geomys and Thomomys pocket gophers (Rodentia: Geomyidae) are reviewed. Catops geomysi n. sp. and Ptomaphagus geomysi n. sp. are described. Both of these species and Ptomaphagus schwarzi Hatch appear to be regular and obligate inhabitants of Geomys burrows b~t are not host specific. Nemadus hornii Hatch, Sciodrepoides watsoni horn ian us (Blanchard), Catops s~mplex Say, Ptomaphagus cavernicola Schwarz, Ptomaphagus consobrinus (LeConte), Ptomaphagus fisus Horn, and Ptomaphagus texanus Horn were less frequently collected and are probably facultative inhabitants of Geomys burrows, as well as nests or dens of other small mammals. Ptomaphagus nevadicus Horn is an inhabitant of ~)Urrows of Thomomys pocket gophers in western North America. A key to the species of Ptomaphagus III the southeastern Gulf Coastal Plain, from non-cave habitats, is provided to aid in their identification.
A list of 35 scale insects collected from 72 ornamental plant species in Sao Carlos, Sao Paulo, Brazil is provided. Regarding host specificity, 30 scale insects were polyphagous, 4 oligophagous, and 1 monophagous. A total of 102 coccoid/plant associations are recorded, 29 of which are new host records for the species; 60 are new host records for the species in Brazil. Pulvinaria urbicola Cockerell, 1893 (Coccidae), Phenacoccus similis Granara de Willink, 1983 (Pseudococcidae), and Orthezia molinarii (Morrison, 1952) (Ortheziidae) are recorded for the first time in Brazil. In addition, we describe the injury caused by scale insects on ornamental plants.
This paper reports on the scarab beetles collected during a survey of nonparasitic arthopods living in burrows of the southeastern pocket gopher (Geomys pinetus Rafinesque, Geomyidae). Three new species are described: Aphodius bakeri, A. baileyi and A. gambrinus. A key to species of Aphodius occurring in these burrows is presented. Distributional data is provided for species of Aphodius and one species of Euphoria
occurring in this microhabitat. Aspects of life histories of burrow inhabiting insects are speculated upon.
This study is a contribution to the knowledge of the weevil species present in the State of Guanajuato, Mexico. During this study, 73 genera and 125 species were identified. The subfamilies best represented were Baridinae, Curculioninae and Entiminae with 24, 24 and 23 species, respectively. The genera best represented were Geraeus and Anthonomus with seven species and Conotrachelus with six, Of the 125 species identified, 18 represent new country records. Of the weevil species found in Guanajuato, 53.7% are Neotropical, 26% are Nearctic, 18.4% are cosmopolitan, and the remainder (1.9%) previously were known only from the West Indies.
Records and descriptions are given for the 10 known species in six genera of Bruchidae from the Archipelago including Sennius falcatus New Species and Acanthoscelides rossi New Species. Amblycerus (Spermophagus) insulamm (Blair) is synonymized with Amblycems piurae (Pierce), New Synonymy. Five of the species herein treated are new records for the Archipelago, and 8 of the 10 are also known from mainland South America, principally Ecuador.
Texas has one of the most diverse orthopteroid assemblages of any state in the United States, reflecting the varied habitats found in the state. Three hundred and eighty-nine species and 78 subspecies of orthopteroid insects (Blattodea, Mantodea, Phasmatodea, and Orthoptera) have published records for the state of Texas. This is the first such comprehensive checklist for Texas and should aid future work on these groups in this area.
New nomenclatural changes are presented for selected North American mordellid beetles (Coleoptera: Mordellidae). The following five genera are newly recorded fi.·om the United States: Mordellaria Ermisch 1950, Falsomordellistena Ermisch 1941, Mordellina Schilsky 1908, Mordellochroa Emery 1876, and
Pseudotolida Ermisch 1950. The following species are transferred from Tomoxia and represent new combinations: Mordellaria borealis (LeConte 1862), Mordellaria fascifera (LeConte 1878), Mordellaria latipalpis (Ray 1946), Mordellaria serval (Say 1835), and Mordellaria undulata (Melsheimer 1845). The following species are transferred fi.·om Mordellistena and represent new combinations: Falsomordellistena hebraica (LeConte 1862) and Falsomordellistena pubescens (Fabricius 1798); Mordellina blatchleyi (Liljeblad 1945), Mordellina pilosella (Ray 1947), Mordellina pustulata (Melsheimer 1845), Mordellina ustulata (LeConte 1862), and Mordellina wichhami (Liljeblad 1945); Mordellochroa scapularis (Say 1824); Pseudotolida
arida (LeConte 1862), Pseudotolida hnausi (Liljeblad 1945), and Pseudotolida lutea (Melsheimer 1845). Mordellina ustulata (LeConte 1862) represents a return to species rank after being treated as a subspecies of Mordellistena andreae LeConte 1862. There are a total of 17 genera of Mordellidae in America north of Mexico.
A new key is presented to separate adults of the four currently-recognized species of the genus Cradytes Casey (Insecta: Coleoptera: Melyridae): C. longicollis Casey, C. serricollis (LeConte), C. serrulatus . (LeConte), and C. ursinus Blaisdell. The inaccurate statements in an earlier key to species of Cradytes are discussed.
Hydrocolus heggiensis : a new species from Georgia and South Carolina (Coleoptera: Dytiscidae)
(2001)
Hydrocolus heggiensis, a new species of predacious water beetle, is described from granite monadnocks in Georgia and one location in South Carolina. It most closely resembles H. stagnalis (Gemminger and Harold) but differs in range, genitalia, and elytral punctation. Photographs, drawings, and an interpolation of the new species into existing keys are given.
Epimechus curvipes Dietz is designated as type species of the genus Epimechus Dietz. Ten additional species from western North America, including four new species, are assigned to the genus: E. aemulus Fall; E. flavirostris Fall; E. mimicus Dietz; E. adspersus Dietz; E. mobilis Fall; E. nevadicus Dietz; E. molina, new species (Arizona, Baja California Norte); E. combustus, new species (Arizona, New Mexico, Utah); E. signum, new species (Arizona, Coahuila, Colorado, New Mexico, Saskatchewan, Texas, Utah) and E. hesperius, new species (Arizona, California, Colorado, Guanajuato, Idaho, Nevada, New Mexico, Nuevo Leon, South Dakota, Texas, Utah, Wyoming). These are distinguished from other Anthonomini by the short, simple tarsal claws. The names Epimeclws modicus Fall, E. soriculus Dietz, and E. nanulus Fall are placed in new synonymy under E. curvipes. Lectotypes are designated for E. adspersus and E. nevadicus. Two species formerly in Epimechus are transferred the subgenus Cnemocyllus Dietz in Anthonomus Germar: E. arenicolor Fall as Anthonomus arenicolor (Fall), new combination, and E. canoides Fall as Anthonomus canoides (Fall), new combination. Adults of species of Epimechus have been collected on plants in the genera Baccharis, Chrysothamnus, Ericameria, Gutierrezia, Haplopappus, Senecio and Tetradymia (all Asteraceae).
Rhyssa neotropicae n. sp. is the first Rhyssa to be recorded from the New World tropics, where it was collected in cloud forest at 1800 m on Monte Uyuca near Zamorano, Honduras. It is closely related to the Nearctic R. hoferi Rohwer and R. howdenorum Townes but differs from all other Rhyssa by its complexly yellow and black marked head and body, whose color pattern mimics that of aggressive social vespid wasps (Agelaia) which occur in the same habitat. Rhyssa howdenorum Townes is recorded for the first time from Florida and Oklahoma. The genus Rhyssella, previously unknown in Florida, is represented in that state by R. perfulua n. sp., distinctive in its mostly orange brown coloration, and by R. humida (Say), a black and white species with fulvous on the thoracic pleura and propodeum.
A new family Coryphoridae is proposed in the superfamily Ephemerelloidea for the monotypic genus Coryphorus. Characters that distinguish Coryphoridae from all other Ephemerelloidea are discussed. The male imago, male subimago, female imago, and egg of Coryphorus aquilus Peters are described for the first time.
Based on adult character states, a key is provided to the seven known species of Oreodicastes Maindron 1905 (type species Oxyglossus subcyaneus Chaudoir 1843). Two new species (with type locality) are described: O. virginia (Fa zenda dos Campos, Virginia, state of Minas Gerais, Brazil) and O. zikani (Macieiras, Itatiaia, state of Rio de Janeiro, Brazil).

The following new synonymies are proposed: Deloyala clauata, var. diuersicollis Schaeffer, 1925, transferred from synonymy with Plagiometriona clauata (Fabricius, 1798) to synonymy withP. clauata testudinaria (Boheman, 1855); Chrysomela hybrida Say, 1824, downgraded from subspecies of Calligrapha lunata (Fabricius, 1787) to full synonym of CaZZigrapha lunata (Fabricius); Chrysomela casta Rogers, 1856, downgraded from subspecies of Zygogramma suturalis (Fabricius, 1775) to full synonym of Zygogrammasuturalis (Fabricius); Trirhabdagurneyi Blake, 1951, downgraded to synonym of Trirhabda caduca Horn, 1893; Scelida mimula Wilcox, 1965, downgraded to synonym of Scelida nigricornis (Jacoby, 1888); Exoracalifornica Wilcox, 1953, downgraded to synonym of Pte leon breuicornis (Jacoby, 1887); alaeothonaarizonensis Blake, 1950, downgraded to synonym ofLupraea discrepans (Schaeffer, 1932); Haltica nigritula Linell, 1898, downgraded to synonym of Nesaecrepida asphalt ina (Suffrian, 1868); Cryptocephalus reinhardi Sundman, 1965, downgraded to synonym of Cryptocephalus nwtabilis Melsheimer, 1847. The tribes Chalepini Wiese, 1910, and Uroplatini Weise, 1910 (Hispinae), are synonymized, and both of these family-group names are recognized as nomina protecta. The family-group name Octotomites Chapuis, 1875, is recognized as a nomen oblitum. Coptocycla testudinaria Boheman, 1855, is downgraded from specific status to a subspecies of Plagiometriona clauata (Fabricius, 1798); Cassida bicolor (Fabricius, 1798) is recognized as a valid subspecies of Charidotellasexpunctata (Fabricius). The genus Hemiphrynus Horn, 1889, is removed from synonymy with Phrynocepha and reinstated as a valid genus; Rhabdopterus weisei (Schaeffer, 1920) is removed from synonymy with Rhabdopterus praetextus (Say) and reinstated as a valid species.
