Young Of The Year

A small school of juvenile Atlantic Whitefish (~20-30 individuals) were observed in the littoral zone of Hebb Lake (Petite Rivière watershed), Nova Scotia in June 2000. Of these, a single individual was captured with a beach seine, and confirmed to be a young-of-the-year specimen. This is the first documented report of the occurrence of wild Atlantic Whitefish juveniles. Occupation of the littoral zone into early summer by young-of-the-year Atlantic Whitefish may have implications for predation by invasive Smallmouth Bass.

AbstractSphaerularia bombi Dufour is an internal nematode parasite of bumble bee queens in North America and Europe. Infection functionally castrates the bee. Here we document the prevalence and intensity of S. bombi infections in seven species of Bombus and three species of Psithyrus on Cape Breton Island, Nova Scotia, Canada. We found dramatic variation in prevalences among Bombus spp., and some evidence that prevalence increased as the nesting season progressed. Also, we report S. bombi in the bumble bee nest parasite Psithyrus insularis (Smith), the first record for the genus in North America.

AbstractLacconotus punctatus LeConte is reported for the first time from Atlantic Canada from a specimen collected in Bridgewater, Nova Scotia. This is the first record of the family Mycteridae in the region. The bionomics and systematics of the species are briefly discussed. The report is also situated in the context of the developing knowledge of saproxylic beetles in the region.

Pseudoterranova Decipiens

Amphipods (Gammarus oceanicus) and mysids (Neomysis americana) were collected from three brackish ponds on Sable Island, 290 km east of Halifax, Nova Scotia. Thirteen nematodes were recovered from 3950 mysids subjected to enzymatic digestion. Four of the nematodes were identified as larval sealworm (Pseudoterranova decipiens). The remaining nematodes belong to two species: Paracuaria adunca and Cosmocephalus obvelatus (Acuarioidea). This is the first record of N. americana as an intermediate host for P. decipiens. It is also the first report of a mysid as intermediate host for either of the acuarioid nematodes and the first evidence of these two nematodes undergoing part of their life cycles in brackish or marine conditions. No nematodes were observed in 2364 amphipods or 1462 mysids examined microscopically, but unidentified metacercariae were found in 1.9% of the amphipods.

In the course of my search for Miridae and Anthocoridae in Nova Scotia in 1976, I collected a series of 33 bugs which proved to be the females of Loricula pselaphiforrnis Curtis, family Microphysidae. The species was collected on the trunks of European beech, Fagus sylvatica var. purpurea Ait., at Point Pleasant Park, Halifax, 22 July 1976. The bugs were first observed as tiny bumps on the trunks, blending perfectly with the bark and small patches of lichens. At first sighting the bumps were thought to be tiny spiders or their egg cases. When disturbed they moved a short distance and again remained motionless. All were brachypterous females, no males were collected, and no specimens were collected by beating the branches. Although other species of tree trunks were examined, no bugs were found. The bugs may have been introduced into this country with nursery stock importations of beech or some other horticultural plants.

First Record

The introduced European weed scentless chamomile, Matricaria perforata Mérat (Asteraceae), is a target for biological control in Canada (Peschken and Sawchyn 1993). As part of this project, the fauna on scentless chamomile in Canada has been investigated (Woo et al. 1991). In 1990, a total of 25 adult Apion weevils were dissected out of 115 flower heads collected at two locations in Antigonish County, Nova Scotia, on 23 August and 4 September. These were identified by D.E. Bright as Apion hookeri Kirby, 1808 (Coleoptera: Curculionidae). The weevil had not been recorded previously in North America.

Herbarium Collections

We conducted a review of herbarium collections of the Wintercress genus (Barbarea W.T. Aiton) from the Maritime provinces. Most specimens previously determined to be the regionally rare native species Erect-fruit Wintercress (Barbarea orthoceras Ledebour) are in fact the uncommon exotic Small-flowered Wintercress (Barbarea stricta Andrzejowski). The latter species is here reported as new to Atlantic Canada, where it is scattered but widespread in the three Maritime provinces. Only three collections (two from New Brunswick and one from Nova Scotia) were confirmed as B. orthoceras. Its known range extent and area of occupancy in the Maritimes has been significantly revised, and B. orthoceras is now considered potentially extirpated in New Brunswick and extremely rare in Nova Scotia. One collection from Nova Scotia was referred to another rare exotic species, Early Wintercress (Barbarea verna (Miller) Ascherson), which represents the first record for the Maritimes.

Here we present the first records of Denheyernaxoides from North America: D. americanus, collected from coniferous litter, soil, and moss in Nova Scotia, Canada. These new records significantly expand the known distribution of the species. Denheyernaxoides americanus is redescribed to include Canadian specimens and to rectify discrepancies in the species’ description identified during examination of the holotype. The deutonymph of D. americanus is also described. Sequences, representing a 658 bp region of the mitochondrial cytochrome c oxidase subunit I (COI), were obtained from representative specimens collected in Canada. Comparison of these sequences with those from the Barcode of Life database (BOLD) suggests that a second species of Denheyernaxoides may occur in British Columbia, Canada. A revised key to world species of Denheyernaxoides is provided.

First collected in North America in 1937 on the Avalon Peninsula of the Island of Newfoundland, the introduced, primarily European land snail, Discus rotundatus, has now been recorded from the Island of Newfoundland, Nova Scotia, New Brunswick, Quebec, Ontario, and British Columbia. We review all known records from Canada, demonstrate that D. rotundatus is more widespread than was previously recognized on the Island of Newfoundland, and report the first record from New Brunswick.
