AbstractThirty species of the genus Lygocoris Reuter known to occur in Canada and Alaska are reviewed. Lygocoris confusus (Knight) is considered to be a synonym of L. contaminatus (Fallen), communis var. novascotiensis (Knight) is a synonym of communis (Knight), caryae var. subfuscus (Knight) is a synonym of caryae (Knight), and canadensis var. binotatus (Knight) is a synonym of canadensis (Knight). The species considered are: pabulinus (Linnaeus), lucorum (Meyer), alni (Knight), artricallus Kelton, atritylus (Knight), belfragii (Reuter), canadensis (Knight), caryae (Knight), clavigenitalis (Knight), communis (Knight), contaminatus (Fallen), fagi (Knight), geneseensis (Knight), hirticulus (Van Duzee), inconspicuus (Knight), invitus (Say), johnsoni (Knight), knighti Kelton, laureae (Knight), omnivagus (Knight), ostryae (Knight), parrotti (Knight), piceicola Kelton, quercalbae (Knight), semivittatus (Knight), tiliae (Knight), univittatus (Knight), viburni (Knight), vilticollis (Reuter), and walleyi Kelton.A key to species, brief redescriptions, illustrations of species and male claspers, distribution maps, and host plants are included. A list of the remaining 10 species known from the United States is appended.

In this manuscript Aonidiella comperei is reported for the first time in Colombia; The specimens were found associated with branches, leaves and fruits of Citrus x latifolia (Rutaceae) in the department of Tolima. Also, we obtained physical evidence of the association of Parlatoria ziziphi and Citrus x limonia (Rutaceae) in Colombia from a sample collected in the field; until this paper the only record of P. ziziphi in the country came from specimens intercepted in a quarantine inspection at a port of entry in the United States. Field and slide-mounted characteristics are provided for A. comperei. Also a taxonomic key to species of Diaspididae present on Citrus spp. in Colombia is given.

In a recent contribution in this Journal, I described a few new Diptera from Canada. The present paper contains descriptions of six new Canadian species and two from the United States, the types of the Canadian species being in the Canadian National Collection. The descriptions of two of the species of Ptiolina in this paper have been prepared by Dr. M. D. Leonard and are included in order that the key to species may be complete. From our study of this genus it seems probable that there are other species to be found, especially in the north where so little collecting has been done.

AbstractTwo exotic species of Xyleborus (Coleoptera: Scolytidae) of Asian origin have recently been detected in the United States. Xyleborus pelliculosus Eichhoff has been collected in Pennsylvania and Maryland, and X. atratus Eichhoff from Tennessee, Georgia, Maryland, Virginia, and West Virginia. Descriptions of both species and a revised, illustrated key to members of the genus Xyleborus in eastern North America are presented. An explanation is proposed for the large numbers of recent introductions of exotic ambrosia beetles from eastern Asia into eastern North America.

Alabama is one of the most speciose states in the United States, yet many common groups of organisms, including assassin bugs (Hemiptera: Heteroptera: Reduviidae), have yet to be fully documented. The purpose of this manuscript is to identify all known assassin bug species occurring in the state using literature records and specimens from natural history collections, most notably the Auburn University Museum of Natural History Entomology Collection, to provide new state records, a checklist, and a morphological species key of the Alabama Reduviidae. All total, 61 species within 36 genera and 10 subfamilies are reported from Alabama. Additionally, 40 new state literature records are documented: 34 from Alabama and six from other states.

The clivinematine genus Ambracius Stål is revised and the three new species Ambracius alineae from Venezuela, A. liviae from the United States (Texas), and A. rudybuenoi from Panama are described and illustrated. The previously known species Ambracius capucinus (Reuter), A. dufouri Stål, A. mexicanus Carvalho, A. pallescens (Distant), A. rubricosus (Distant), and A. vittatus Carvalho are redescribed. A key to species is provided to aid in identification.

The family Platypodidae includes approximately 1,000 species, most of which are found in the tropics (Schedl 1972). Seven species of platypodids, all in the genus Platypus, are found in the United States, four of which occur in Florida. All species found in Florida are borers of trunks and large branches of recently killed trees and may cause economic damage to unmilled logs or standing dead timber. The most recent key to species was published 60 years ago (Chamberlin 1939), does not include all species known from the United States (Wood 1979), and has long been out of print. This document is EENY-174 (originally published as DPI Entomology Circular 321), one of the Featured Creatures series of the Entomology and Nematology Department, Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Published: November 2000. Revised: March 2004.  EENY174/IN331: Ambrosia Beetles, Platypus spp. (Insecta: Coleoptera: Platypodidae) (ufl.edu)
