Revision of Heterocloeon McDunnough (Ephemeroptera: Baetidae)

JIS: McCafferty 5.35.2005

The North American genus Heterocloeon McDunnough is redefined and shown to be distinct from other two-tailed Baetis complex genera, including Acentrella Bengtsson and Plauditus Lugo-Ortiz and McCafferty, which are also represented in North America. Heterocloeon is divided into three distinct subgenera, including Heterocloeon s.s., Iswaeon McCafferty and Webb, new subgenus, and Jubilatum McCaffe...

New larvae of Baetidae (Insecta: Ephemeroptera) from Espiritu Santo, Vanuatu

During the Global Biodiversity Survey “Santo 2006” conducted in Espiritu Santo, Vanuatu, mayfl y larvae were collected in several streams of the island. This contribution deals with the larvae of Baetidae (Insecta: Ephemeroptera) that are represented by two species: Labiobaetis paradisus n. sp. and Cloeon sp. The presence of these two genera is not surprising as they both possess almost a world...

Cryptic diversity and multiple origins of the widespread mayfly species group Baetis rhodani (Ephemeroptera: Baetidae) on northwestern Mediterranean islands

Paracloeodes caldensis (Ephemeroptera: Baetidae), an atypical new species from the Colombian Andes.

In the present work, an atypical new species of Paracloeodes Day (Ephemeroptera: Baetidae) is described based on nymphs collected in the Caldas Department, Central Cordillera of Colombia. This represents the first report of the genus from Colombia. The main characteristics that distinguish the new species from congeners are: abundant setae on femora, antennae length twice the width of the head ...

A New Species of the Genus Neoephemera McDunnough from China (Ephemeroptera: Neoephemeridae)

The mature larva of a new species, Neoephemera projecta sp. n., from China is described in detail. It represents a new country record of the genus for China. The discovery shows that the genus Neoephemera McDunnough has a more extensive Holarctic distribution than previously known. Ecological vicariance instead of geographic isolation is therefore favoured as presumed cause of the origin of the...
