The woodwasp, Xiphydria canadensis Provancher, is a rare insect restricted to northeastern North America. Provancher (1875) based his original description on a single female collected at St. Hyacinthe, Quebec. In his recent revision, Smith (1976) saw only five females. On 7 August 1977, I collected a specimen of this large and distinctive species on the north side of Hwy. 60, at Mile 12.7, just west of the Park Museum in Algonquin Provincial Park, Ontario. This collection constitutes the first record for this species in Ontario.

An account is given of some Microsporidia found in certain fishes and insects in eastern Canada, among which are new species of Nosema, Perezia and Gurleya.Nosema pimephales n.sp. produces large cysts or tumours in the abdomen of Pimephales promelas, one out of a large number from Lake Guindon, Province of Quebec, being infected.Nosema branchiale Nemeczek has been observed from a cod, Gadus callarias. The organism is shown to be a Nosema, though the incomplete original description has caused doubts as to whether some other genus was involved. Further details are now given.Nosema apis Zander and N. bombi Fantham & Porter have been found in Canada in hive-bees and humble-bees respectively, the latter being recorded from a new host, Bombus vagans.Glugea hertwigi n.var. canadensis is described from Osmerus mordax from Lake Edward.Perezia aeschnae n.sp. has been found in nymphs of the large dragonfly, Aeschna grandis, collected near Montreal and is described and illustrated.Perezia legeri Paillot has been observed in larvae of Pieris brassicae.These appear to be the first records of Perezia from insects in North America, and the zoogeographical distribution of the genus is extended to the Odonata.Gurleya aeschnae n.sp, is described from a nymph of Aeschna grandis. It is the first species of Gurleya to be described from the Odonata and the first record of the genus from the North American continent.Thelohania corethrae Schuberg & Rodriguez is described from the larvae of Chaoborus flavicans. Measurements of the parasite, which were lacking in the original description, are now supplied.Thelohania bracteata from larvae of Simulium bracteatum and larvae and one adult S. venustum and Thelohania fibrata from larvae of Simulium venustum are recorded from places in the Province of Quebec. The need of reinvestigation of the species of Thelohania from various Simulium and the possibility of there being but one species, Thelohania varians Debaisieux, are indicated.Thelohania legeri Hesse is recorded as a parasite of larvae of Anopheles punctipennis in Quebec Province and of A. gambiae in Zululand. It is probably the most widely distributed species of Thelohania, occurring in Anophelines in Europe, Asia, Africa and North America.Some general remarks regarding zoogeographical distribution, habitat, host-specificity and possible origin of species and varieties in connexion with Gurleya, Perezia and Thelohania are presented.

The European species of Calymmochilus Masi (Hymenoptera, Eupelmidae) are revised. Calymmochilus atratus Masi stat. rev. is removed from synonymy under C. subnubilus (Walker) and treated as a valid species. A lectotype is designated for Calymmochilus atratus. The single extant type specimen of Eupelmus subnubilus Walker is considered as lectotype. Calymmochilus bini Fusu sp. n. is described from a single female collected in Sardinia. A female of Calymmochilus russoi Gibson is reported from Spain as a parasitoid in galls of Parapodia sinaica (Frauenfeld) (Lepidoptera, Gelechiidae) on Tamarix (Tamaricaceae), a new national and host record. The species is redescribed and illustrated, this being the first record of the species after its original description. An illustrated key to females and, when known, males of the now six recognized European species of Calymmochilus is given and available biological and distributional data are reviewed.

Two new oversize troglobitic species of diplurans campodeids, Pacificampadaidarabotchi Sendra, sp. n. and Pacificampanipponica Sendra, sp. n., found in three caves in two southern Japanese islands are described. It is the first record of cave-dwelling Diplurans from Japan and more specifically these are two Campodeinae of Pacificampa Chevrizov, 1978 formally known in continental Asia with three cave-dwelling species described in Russia and China near the north of the Korean peninsula. In P.daidarabotchisp. n., in addition to its oversized body, the longest ever known in campodeids family, it shows as its main differential taxonomical feature the absence of lp metanotal macrosetae. P.nipponicasp. n. is much closer to continental Pacificampa species but it shows differences in the urotergal macrosetae formula. Both Japanese species have clear troglomorphic features related with their elongated body and appendages and an increase in number and complexity of the sensorial antennal equipment with unique olfactory chemoreceptors. Two biogeographical remarks are inferred: P.nipponicasp. n., has been found in two islands that were connected during the glacial age and P.daidarabotchisp. n. lives in a single cave near another where P.nipponicasp. n. dwells which allowing to suggest a sympatric distribution; Pacificampa seems to be related with Eumesocampa, a genus from North-America, as a consequence of the Holarctic connection between Asia and America. The interests of P.daidarabotchisp. n. and P.nipponicasp. n. as endemic species in addition to their biogeographical importance should be taken into consideration to ensure better management of the three touristic caves where they dwell and especially the protection of Mejido-do cave, the only location of the large P.daidarabotchisp. n. near to an active quarry.

AbstractMustela macrodon (extinct sea mink) is known only from prehistoric and historic Native American shell middens dating less than 5100 years old along coastal islands of the Gulf of Maine, northeastern North America. The species is distinct from all known extant subspecies of M. vison (American mink) but still belongs to the North American subgenus Vison. Metric comparisons between M. macrodon and five subspecies of M. vison, using skull, mandible, humerus, radius, femur, and tibia skeletal elements, show that M. macrodon is larger in overall size and robustness and is proportionately larger in the dental region. Many habitat-related parallels exist between coastal island mink of the Gulf of Maine and those of the Alexander Archipelago, southeastern Alaska, where the overall largest living subspecies of mink is found (M. v. nesolestes).

Abstract An interdecadal weakening in the North Atlantic storm track (NAST) and a poleward shift of the North Pacific storm track (NPST) are found during October–March for the period 1979–2015. A significant warming of surface air temperature (Ts) over northeastern North America and a La Niña–like change in the North Pacific under the background of Arctic amplification are found to be the contributors to the observed changes in the NAST and the NPST, respectively, via modulation of local baroclinicity. The interdecadal change in baroclinic energy conversion is consistent with changes in storm tracks with an energy loss from eddies to mean flow over the North Atlantic and an energy gain over the North Pacific. The analysis of simulations from the Community Earth System Model Large Ensemble project, although with some biases in storm-track and Ts simulations, supports the observed relationship between the NAST and Ts over northeastern North America, as well as the link between the NPST and El Niño–Southern Oscillation. The near-future projections of Ts and storm tracks are characterized by a warmer planet under the influence of increasing greenhouse gases and a significant weakening of both the NAST and the NPST. The potential role of the NAST in redistributing changes in Ts over the surrounding regions is also examined. The anomalous equatorward moisture flux associated with the weakening trend of the NAST would enhance the warming over its upstream region and hinder the warming over its downstream region via modulation of the downward infrared radiation.

The North American species of Limnocoris are revised and total 13 species after the present study. Four new species are described and illustrated: L. chaetocarinatus n. sp. from Costa Rica, Panama, and Colombia; L. major n. sp. and L. nanus n. sp. from Costa Rica and Panama; and L. zacki n. sp. from Mexico and Guatemala. Further, supplemental descriptions are provided for the previously described species. The following synonymies are proposed, with junior synonyms in brackets: L. insularis Champion [L. alcorni La Rivers n. syn.], L. pygmaeus La Rivers [L. solenoides La Rivers n. syn.], and L. signoreti Montandon [L. brailovskyi La Rivers n. syn., L. laucki La Rivers n. syn., L. stangei La Rivers n. syn.]. A lectotype is designated for L. signoreti. Limnocoris profundus (Say) is considered a nomen dubium because no type specimens have been found and the original description is insufficient to establish its identity. An illustrated taxonomic key, distribution maps, and a discussion of the characters (putative synapomorphies) not previously mentioned in the literature also are presented.

The freshwater planktonic calanoid copepod Leptodiaptomus dodsoni Elías-Gutiérrez, Suárez-Morales & Romano, 1999, a rare species known only from western Mexico, is here recorded from the State of Aguascalientes, central Mexico. This species has a uniquely large, sinuous spine on segment 13 of the right male antennule, reaching the distal margin of segment 15. There are subtle differences between these two known populations; the morphological range of the species is complemented with data from the new specimens. This is the first record of L. dodsoni after its original description; it is probably restricted to a latitudinal fringe in central Mexico. Of the 22 nominal species of Leptodiaptomus currently recognized, up to 7 are known from the Neotropical region and some appear to be true endemics. Apparently, this primarily Nearctic genus radiated in North America and some species reached the Neotropical region where they diversified. A key for the identification of the species of the genus known from the Neotropical region is also provided.

Abstract In this research, we report the presence of two ciliate protozoans of the subclass Peritrichia, Cothurnia amphicteis and C. peloscolicis, as epibionts on the chaetae of scaled polychaetes Malmgrenia lilianae, M. andreapolis (fam. Polynoidae) and Sthenelais boa (fam. Sigalionidae), from the north Adriatic (Mediterranean Sea). Both ciliate species are herein found for the first time after their original description and are redescribed, based on light and scanning electron microscopy analyses. This is the first record of an association between ciliates and polychaetes of the family Sigalionidae. Our results suggest that these host–epibiont relationships might be highly specific. We also present the first review of epibiosis between polychaetes and peritrich ciliates, indicating that this relationship is more diverse than previously thought. Forty taxa of peritrich ciliates from 12 genera and seven families are recorded as epibionts on polychaetes, while 48 polychaete taxa are known as their hosts. The relationship can be considered ectocommensalism, where the ciliates have the advantages of increased food availability. This association might be a more widespread phenomenon than currently known, because it could be easily overlooked or misinterpreted. It, therefore, deserves careful attention and further investigation.

Saxifraga Oppositifolia

Growth forms and the presence or absence of hairs on the surfaces of the sepals of Saxifraga oppositifolia L. plants were examined on type specimens and more than 400 herbarium specimens collected from all over North America and Europe. Data were gathered on whether plant growth forms were compact, trailing, or intermediate between the extremes. Specimens were examined for whether or not hairs were present on the surface of the sepals between the long trichomes on the margins, and if so, an estimate was made of the degree of hairiness. While extreme forms of compact and trailing plants do occur, maps indicate that more of the plants collected in North America were intermediate in growth form. The geographic distribution of the presence or absence of hairs on the sepals is mapped, as is the gradation in degree of hairiness of sepals. The type specimen of S. oppositifolia subsp. smalliana (S. pulvinata), from the Yukon, has compact plants and flowers that have sepal surfaces with a few sparse hairs. The flowers have set fruits that have opened. “The smaller turbinate hypanthium” described in the original description may be the result of the structures being dehisced and dried up fruits. The type specimen of S. oppositifolia subsp. glandulisepala , from Alaska, is a relatively trailing specimen with some larger leaves. The sepal surfaces have a few glandular hairs. Whether or not the hairs appear glandular on herbarium specimens may reflect the stage of flowering at the time of collection. No morphological differences are associated with three different chromosome numbers known for S. oppositifolia plants from the area of the North American type specimens, and DNA analyses done mainly on European specimens, but also including a potential candidate for the name “smalliana”, gave inconclusive results. Thus, chromosome and DNA data join these morphological data on growth forms and the occurrence of sepal hairs to discourage recognizing subspecies among plants occurring in North America.
