Habitat requirements affect genetic variation in three species of mayfly (Ephemeroptera, Baetidae) from South Africa

Small-scale patterns of genetic variation in the mayfly Bungona narilla (Ephemeroptera: Baetidae) in rainforest streams, south-east Queensland

1. Genetic structure of the mayfly Bungona narilla was examined using allozymes and a section of the cytochrome oxidase I gene. 2. The study had two major aims. The first was to determine whether patterns of genetic variation in mitochondrial DNA were similar to those found previously for allozymes, i.e. that more variation was evident among pools within a single stream than among streams. The ...

New species of Indocloeon Müller-Liebenau from South-East Asia (Ephemeroptera, Baetidae)

One new species of Indocloeon Müller-Liebenau from Brunei, I. spathasetissp. n., and one new species from Indonesia, I. timorensesp. n., are described and illustrated based on their larvae. The total number of known Indocloeon species increases from two to four and the generic attributes of the larvae are amended based on the examination of the new species. Results on the genetics of some speci...

Discovery of an alien species of mayfly in South America (Ephemeroptera)

Despite its wide, almost worldwide distribution, the mayfly genus Cloeon Leach, 1815 (Ephemeroptera: Baetidae) is restricted in the Western hemisphere to North America, where a single species is reported. In the Neotropics, except for some species wrongly attributed to the genus in the past, there are no records of Cloeon. Recently, however, specimens of true Cloeon were collected along the coa...

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

Further notes on South American species of Baetidae (Ephemeroptera) assigned to Moribaetis Waltz & McCafferty, 1985.

The types of the remaining two South American species classified in Moribaetis Waltz & McCafferty, 1985 were studied. Moribaetis comes (Navás, 1912) is designated as a nomen dubium based on the lack of information in the original description, the damaged type and the resultant improbability of assigning specimens to this species. The type-material of M. aneto (Traver, 1971), on the other hand, ...
