Hyrtanella spp.

Discussion. We recommend that Hyrtanella female alates should not be identified to species until adults are associated positively with both H. christineae and H. pascalae . Allen and Edmunds (1976) had described female adults for H. christineae , but the association was not based on rearing, and the size of those female adults is similar to what would be expected from H. pascalae , rather than the larger H. christineae . The adults described by Allen and Edmunds (1976) probably belong to the genus Hyrtanella , because they share with the larvae the shape and armature of the abdomen, which is unique among genera of the family Ephemerellidae (sensu Wang & McCafferty 2000).

Material examined. Island of Borneo—MALAYSIA (east), Sabah, Liwagu R, N of Kundassan, 915m, 16–17/VIII/1972, WL&JG Peters, 15 female adults [ FAMU].
