Introduced Staphylinidae (Coleoptera) in the Maritime Provinces of Canada
Bibliographic record
Abstract
The fauna of introduced rove beetles (Staphylinidae) in the Maritime Provinces of Canada is surveyed. Seventy-nine species have now been recorded. Of these, 73 have been found in Nova Scotia, 29 on Prince Edward Island, and 54 in New Brunswick. Twenty-five species are newly recorded in Nova Scotia, 16 on Prince Edward Island, and 10 in New Brunswick, for a total of 51 new provincial records. Of these, 15 species, Tachinus corticinus Gravenhorst, Mycetoporus lepidus (Gravenhorst), Habrocerus capillaricornis (Gravenhorst), Aleochara (Xenochara) lanuginosa Gravenhorst, Gnypeta caerulea (C.R. Sahlberg), Atheta (Microdota) amicula (Stephens), Cordalia obscura (Gravenhorst), Drusilla canaliculata (Fabricius), Deleaster dichrous (Gravenhorst), Coprophilus striatulus (Fabricius), Carpelimus subtilis (Erichson), Leptacinus intermedius Donisthorpe, Tasgius (Rayacheila) melanarius (Heer), Neobisnius villosulus (Stephens), and Philonthus discoideus (Gravenhorst), are newly recorded in the Maritime Provinces. Two of these, Atheta (Microdota) amicula and Carpelimus subtilis, are newly recorded in Canada. Leptacinus intermedius is removed from the faunal list of New Brunswick and Philhygra botanicarum Muona, a Holarctic species previously regarded as introduced in North America, is recorded for the first time in the Maritime Provinces. An examination of when species were first detected in the region reveals that, on average, it was substantially later than comparable dates for other, better known families of Coleoptera — an apparent indication of the comparative lack of attention this family has received. Some introduced species appear to be associated with the dry-ballast mechanism of introduction to the continent, while others are synanthropic and may have been inadvertently introduced in connection with agriculture, horticulture, or other processes associated with human activities. A substantial number are now established and well distributed, seemingly indicative of an early introduction into the region, the ability to successfully colonize a habitat and disperse within it, or a combination of these factors. Other species appear to be local in distribution, perhaps indicative of more recent introductions, more restricted ecological tolerances, a lesser ability to disperse, or a combination of these factors. These recent discoveries are discussed briefly in the context of the importance of taxonomic research and ongoing monitoring in order to detect and identify exotic species and monitor for new introductions and changes in existing native or introduced populations — all important in terms of assessing the risk of introductions to, and their impact on, native faunas and habitats.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
