921787F1F1089942B3F2FE0FFC18BAEF.taxon	distribution	Dineutus hornii is newly recorded on Prince Edward Island. Species of Dineutus are found on the surface ponds, streams, lakes and rivers where they often form large rafts of individuals (Roughley 2000 a).	en	Majka, Christopher (2008): The aquatic Coleoptera of Prince Edward Island, Canada: new records and faunal composition. ZooKeys 2 (2): 239-260, DOI: 10.3897/zookeys.2.25
921787F1F1089942B3F2FE0FFC18BAEF.taxon	description	Roberts (1895, pp 284) described this species as Dineutus hornii, the specific epithet spelled with two “ i’s ”. Subsequently some authors (i. e. Leng 1920; Roughley 1991 b; Laplante et al. 1991; Dearborn and Donahue 1993; Downie and Arnett 1996; Chandler 2001) dropped the second “ i ”, incorrectly spelling the name “ Dineutus horni ”. Accordingly the name Dineutus horni is designated as an incorrect subsequent spelling of Dineutus hornii Roberts, 1895 (Article 33.3, ICZN 1999).	en	Majka, Christopher (2008): The aquatic Coleoptera of Prince Edward Island, Canada: new records and faunal composition.

921787F1F1089942B3F2FF69FBBFB81F.taxon	discussion	Adults glide on the surface of ponds, lakes, and slow-moving rivers. Th ey often congregate and swim rapidly in circles when alarmed, giving rise to their common name of whirligig. Adults are scavengers, feeding on dead and dying insects on the water surface, whereas larvae are predaceous on insect larvae and nymphs (Roughley 2000 a).	en	Majka, Christopher (2008): The aquatic Coleoptera of Prince Edward Island, Canada: new records and faunal composition.

921787F1F104994EB3F2FE2CFCBABA84.taxon	distribution	Newly recorded on Prince Edward Island, this species favours temporary pools and muddy or weedy margins of ponds or lakes (Smetana 1988). This adventive, Palaearctic species was first reported in North America by Darlington (1927). Smetana (1985) examined specimens from as early as 1904 from Montreal, although Brown (1940) noted a specimen from Chicoutimi, Québec, from the “ second ” collection of Provancher acquired sometime between 1877 and 1892. The earliest records from New Brunswick are in 1926 and from Nova Scotia in 1947 (Smetana 1985) so the collection from 1923 on Prince Edward Island establishes a new early timeline for H. grandis in the Maritime Provinces of Canada.	en	Majka, Christopher (2008): The aquatic Coleoptera of Prince Edward Island, Canada: new records and faunal composition.

921787F1F1039949B3F2FD79FD4FBCDA.taxon	distribution	Newly recorded on Prince Edward Island, this species favours shallow standing water or margins of slow-flowing creeks with vegetation. It is also frequently found in semi-aquatic habitats (Smetana 1988). The zoogeographic status of this species is unclear. Smetana (1988) regarded it as an apparently Palaearctic species introduced to North America. He also drew attention to the fact that it appeared that two species, A. lutescens (Stephens 1829) and A. limbata, were being confused under the name of A. limbata in North America. Albrecht Komarek (pers. comm.), who is revising the genus worldwide, points out that while A. limbata and A. lutescens are readily separable in Europe, North American specimens cannot unambiguously be assigned to either species. He believes that North American specimens may represent a separate, undescribed “ cryptic ” species in the lutescens complex. Morphological examinations cannot resolve the problem and it may require molecular phylogenetic analysis in order to discern the nature of this “ species. ” Thus, in the present treatment, I provisionally treat it as a Nearctic species in the lutescens complex whose status has yet to be fully discerned.	en	Majka, Christopher (2008): The aquatic Coleoptera of Prince Edward Island, Canada: new records and faunal composition.
