The algal flora at two selected sites on the Digby Neck Peninsula, Bay of Fundy, was examined at monthly intervals for a year. One hundred and eighty-seven species and varieties were recorded; of these 76 are newly recorded for the Bay of Fundy and 11 are new records for North America. A taxonomic listing, inclusive of reproductive structures found during the year, is given. Seasonal changes and vertical migration of the algae are discussed.

From May to October 2017 seaweeds were identified in the field and laboratory from 20 sites around Brier Island, Nova Scotia. While most sites were intertidal rocky shores, there were one small salt marsh and one eelgrass bed included in the study, and some subtidal sampling was conducted utilizing SCUBA and snorkeling. The Brier Island seaweeds comprised 152 species and varieties of which 62 were Rhodophyta, 44 were Chlorophyta, 44 were Phaeophyceae, and two species were Xanthophyceae. Three species were new records for eastern Canada: Colaconema bonne- maisoniae, C. endophyticum, and Elachista stellaris, all were pre- viously recorded from New England. The flora included eight non- native species of which Colpomenia peregrina and Bonnemaisonia hami- fera (both gametophytic and tetrasporophytic stages) were abundant at two or more sites, and the invasive Codium fragile subsp. fragile was recorded based on a single drift specimen. With 150 species and varieties of seaweeds, Brier Island has the highest species richness of a limited area of eastern Canada. The Cheney floristic index at 2.4 is higher than comparable areas, and suggests that many additional brown algae remain to be found.Keywords: Chlorophyta, Colaconema, Bay of Fundy, Brier Island, Phaeophyceae, Rhodophyta, seaweeds

Mined leaves were collected in commercial and unsprayed (no insecticides) apple orchards of Quebec and Nova Scotia to determine the relative abundance and diversity of parasites of the spotted tentiform leafminer, Phyllonorycter blancardella [Lepidoptera: Gracillariidae]. In Quebec, 29 species of leafminer parasites were recovered, belonging to 7 families: Aphelinidae, Braconidae, Chalcidae, Eulophidae, Ichneumonidae, Pteromalidae and Scelionidae. The most prevalent species were Pholetesor ornigis (67%), Sympiesis marylandensis (11%), S. serviceicornis (7%), Pnigalio maculipes (1.5%), Tetrasticus spp. (1.2%), while all other species accounted for < 1.0%. Pholetesor pedias, a braconid released in 1983 at Frelighsburg, Quebec, was not found in the 1984 and 1985 surveys. In Nova Scotia, 19 parasite species were recovered, belonging to 5 families : Braconidae, Encyrtidae, Eulophidae, Ichneumonidae and Pteromalidae. The most prevalent species were: Pholetesor ornigis (52%), Pnigalio maculipes (14%), Sympiesis serviceicornis (12%), S. marylandensis (9.5%), Sympiesis spp. (5%), Horismenus fraternus (1.8%), Paraleurocerus sp. (1.3%), Stictopisthus flaviceps (1.1%), while all other species accounted for < 1%. Seven and five species of hyperparasites were recovered in Nova Scotia and Quebec, respectively. New records for North America for the spotted tentiform leafminer as a host are : Sticopisthus bilineatus, S. flaviceps, Euderis sp., Pnigalio epilobii, P. pallipes and Paraleurocerus bicoloripes.

This note deals with three European species of Orthotylinae now known to occur in Canada. Pilophorus confusus was discovered in 1976 in Nova Scotia and is reported for the first time from the Nearctic region. Additional distribution records are given for Orthotylus nassatus and O. viridinervis previously reported from North America by Henry (1977) and Henry and Wheeler (1979), respectively. The three species were likely introduced accidentally into this country some time ago with nursery stock importations but remained undetected until recently. They are predatory and overwinter in the egg stage. The adults of the three species are illustrated.

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.

The macroalgal flora of the Island of São Miguel (eastern group of the Azores Archipelago) has attracted the interest of many researchers in the past, the first publications going back to the nineteenth century. Initial studies were mainly taxonomic, resulting in the publication of a checklist of the Azorean benthic marine algae. Later, the establishment of the University of the Azores on the Island permitted the logistic conditions to develop both temporal studies and long-term research and this resulted in a significant increase on research directed at the benthic marine algae and littoral communities of the Island and consequent publications. Prior to the present paper, the known macroalgal flora of São Miguel Island comprised around 260 species. Despite this richness, a significant amount of the research was never made public, notably Masters and PhD theses encompassing information regarding presence data recorded at littoral and sublittoral levels down to a depth of approximately 40 m around the Island and the many collections made, which resulted in vouchers deposited in the AZB Herbarium Ruy Telles Palhinha and the LSM- Molecular Systematics Laboratory at the Faculty of Sciences and Technology of the University of the Azores. The present publication lists the macroalgal taxonomic records, together with information on their ecology and occurrence around São Miguel Island, improving the knowledge of the Azorean macroalgal flora at local and regional scales. A total of 12,781 specimens (including some identified only to genus) belonging to 431 taxa of macroalgae are registered, comprising 284 Rhodophyta, 59 Chlorophyta and 88 Ochrophyta (Phaeophyceae). Of these, 323 were identified to species level (212 Rhodophyta, 48 Chlorophyta and 63 Ochrophyta), of which 61 are new records for the Island (42 Rhodophyta, 9 Chlorophyta and 10 Ochrophyta), one an Azorean endemic (Predaea feldmannii subsp. azorica Gabriel), five are Macaronesian endemisms (the red algae Botryocladia macaronesica Afonso-Carrillo, Sobrino, Tittley &amp; Neto, Laurencia viridis Gil-Rodríguez &amp; Haroun, Millerella tinerfensis (Seoane-Camba) S.M.Boo &amp; J.M.Rico, Phyllophora gelidioides P.Crouan &amp; H.Crouan ex Karsakoff and the green alga Codium elisabethiae O.C.Schmidt), 19 are introduced species (15 Rhodophyta, two Chlorophyta and two Ochrophyta) and 32 are of uncertain status (21 Rhodophyta, five Chlorophyta and six Ochrophyta).

Collections were made from various sites in Nova Scotia and Prince Edward Island for small green benthic marine algae, filamentous species associated with other plants, animals, wood, shells, or stones. Identifications were based on observations in situ and material isolated into culture. Twenty species, distributed in 14 genera, were identified; six are new records for eastern Canada and a seventh species is a new record for the Maritime provinces.

Phloeocharis subtilissima Mannerheim (Coleoptera: Staphylinidae: Phloeocharinae), a Palearctic staphylinid, and Cephennium gallicum Ganglbauer (Coleoptera: Scydmaenidae: Cephenniini) are recorded for the first time for North America from Point Pleasant Park, Halifax, Nova Scotia, Canada. The bionomics of both species are discussed based on European data in addition to new observations of their ecology in Nova Scotia. The role of port cities, such as Halifax, in relation to the introduction of exotic Coleoptera is discussed with examples of other species introduced to North America from this location. The earliest known record of Meligethes viridescens (Fabricius) for North America and the second and third reported locations of Dromius fenestratus Fabricius are also presented.

AbstractThe identity, richness, and abundance of true flies (Diptera) from the nests of three cavity-nesting raptors (Aves) were investigated in northern Nova Scotia, Canada. After fledging, flies were extracted from the nest material using Berlese funnels within an emergence chamber. Thirty-one species/morphospecies from 14 families were collected, including eight new records for Nova Scotia and two new records for eastern North America.
