oa African Entomology - A taxonomic and ecological review of Pseudocloeon glaucum (Agnew) (Ephemeroptera: Baetidae)
Pseudocloeon masai (Lugo-Ortiz & McCafferty), P. nadineae (Lugo-Ortiz & McCafferty) and P. quintum (Agnew) are junior subjective synonyms of P. glaucum (Agnew). Larvae of P. glaucum manifest a wide range of variation in mouthpart morphology, particularly with respect to the development of the distomedial process of segment 2 of the labial palps, body size, general body colour and abdominal colour pattern. Such variation is observed in different cohorts and populations, and explains why several names have been applied to the same species. Larvae of P. glaucum also have considerable ecological tolerance, accounting for the abundance and widespread distribution of the species in the Afrotropical Region. New records from Kenya, Lesotho, Namibia and Zimbabwe are provided.
