Caudatella columbiella (McDunnough, 1935), new combination, (Insecta: Ephemeroptera: Ephemerellidae) is removed from synonymy with Caudatella heterocaudata (McDunnough, 1929), and a new junior synonym is recognized, based on comparative examination of type material and larval exuviae associated with adults from the type locale of C. columbiella (=C. californica (Allen and Edmunds, 1961), new status, new synonym). Caudatella circia (Allen and Edmunds, 1961), new status, is recognized as a strict… 

The state of systematics of North American Baetis Leach, 1815 (Ephemeroptera: Baetidae), with recommendations for identification of larvae.

The North American species of Baetis Leach (Ephemeroptera: Baetidae) are reviewed and a scheme for identifications incorporating previously established species groups and the species complexes and species included within them is recommended.

Ephemeroptera of Canada

A total of 66 more species overall is anticipated for Canada, with greatest gains potentially coming from lentic habitats across Canada and from far eastern and far western areas in general.

Phylogenomic Evidence Overturns Current Conceptions of Social Evolution in Wasps (Vespidae)

The results reject the single origin of eusociality hypothesis, contest the supposition that eussociality emerged from a casteless nest-sharing ancestor, and suggest that eUSociality in Polistinae’+ Vespinae began with castes having morphological differences, suggesting that the climb up the ladder of sociality does not occur through sequential mutation.

The generic classification of Ephemerellidae Klapálek (Ephemeroptera) is reviewed and revised, and a higher classification ofEphemerelliinae is proposed based on the naming of groups from these trees.

Subgeneric Groups within the Mayfly Genus Ephemerella (Ephemeroptera: Ephemerellidae)

The currently recognized Ephemerella species are assigned, as fur as possible, to nine subgenera based on nymphal and imaginal characters, which can not be assigned subgenerically without further study.
