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.
