AbstractThe last-instar nymph of the nabid Lasiomerus annulatus (Reuter) is described for the first time and a diagnosis of the adult is presented. Its geographical distribution is detailed and the northern limit of its range in North America is established at 45 °37′N latitude. New phenological and ecological information is provided based on collections made in Québec from 1979 to 1985 and the bioecology is discussed, especially with regard to habitat preferences and phenological cycle.

In August 2004, examination of powdery mildew-infected ‘Russet Burbank’ potato leaves from a furrow-irrigated field in Grant Co., WA, revealed two powdery mildew fungi, one referable to Erysiphe orontii and the other to Leveillula taurica (Lév.) G. Arnaud. Discovery of the two species sporulating together on diseased leaves is consistent with an observation made in the Middle East. This report documents, for the first time, L. taurica on potato in N. America and provides information on distinguishing it from E. orontii. Accepted for publication 9 December 2004.

AbstractThe Eurasian nabid Himacerus apterus (Fabricius) is reported for the first time for North America. Several individuals have been collected between 1943 and 1989 in eastern Nova Scotia. Generic and specific diagnoses are given, and the genus is inserted in Slater and Baranowski’s (1978) key to the genera of North American Nabidae. The geographical distribution and bionomics of the species are briefly discussed.

The lungworm nematode Varestrongylus alpenae (Dikmans, 1935) Dougherty, 1945 is reported in Canada for the first time. Dorsal-spined, first-stage nematode larvae were found in 19% of 1098 fecal pellet groups of white-tailed deer (Odocoileus virginianus) randomly collected in central and eastern Saskatchewan. These larvae developed to the infective stage, experimentally, in the gastropods Triodopsis albolabris and Triodopsis multilineata and were infective to captive mule deer (Odocoileus h. hemionus) and white-tailed deer fawns. All of four mule deer and two of three white-tailed deer developed patent infections (mule deer in 43–49 days and white-tailed deer in 54–55 days). Adults nematodes, identified as Varestrongylus alpenae, were recovered from the lung parenchyma of two mule deer. The geographical distribution of V. alpenae in white-tailed deer in North America is discussed.

AbstractPelosoma pecki is described as new from specimens from the Florida Keys (Upper Matacumba Key) and from Mexico (Oaxaca). The genus Genyon Smetana 1978 (type-species Cercyon navicularis Zimmerman 1869, from eastern North America) is placed in synonymy with Tectosternum Balfour-Browne 1958 (type-species T. exstriatum Balfour-Browne 1958, from equatorial Africa). A lectotype is designated for Pelosoma prosternale Sharp 1882, and Pelosoma praecursor Smetana 1978 is placed in synonymy with P. prosternale Sharp 1882.Omicrus intermedius Smetana and the genus Cycrillum Knisch, with the species C. strigicolle (Sharp), are recorded for the first time from North America.Additional data on bionomics, geographical distribution, and synonymy of many species are presented.

A New Species

A reappraisal is presented of the taxonomy of three of the four alternate-leaved species of Chrysosplenium occurring in North America, namely C. tetrandrum, C. iowense, and C. Rosendahlii, the latter a new species described for the first time. The investigation demonstrates that the species can be readily separated morphologically even as seedlings. Each morphological entity is characterized by a different chromosome number, C. tetrandrum 2n = 24, C. Rosendahlii 2n = 96. C. iowense 2n = c.120, and a distinctive geographical distribution. C. iowense, which has on occasions been regarded as identical with C. alternifolium var. sibiricum, is retained as a species in the absence of a modern taxonomic analysis of the Old World species C. alternifolium.

AbstractPineus pineoides was found for the first time in North America in New Brunswick in 1948, on red spruce, Picea rubens Sarg. It is the first known species of Adelgidae in North America to complete its life cycle on spruce without producing galls or winged forms. The life history is compared with that in Europe. The first-instar nymph and the adult of the summer generation are described and compared with those from Europe.
