Abstract

Nine genera and twenty-two species of heptageniid mayflies from Thailand are defined in this present work as well as one suggested further subgenus, Compsoneuria (Siamoneuria) kovaci (species “incertae sedis”) including some particular characters. Taxonomic remarks, diagnoses, line drawings of key characters, distribution, habitat and biological data, and a larval key to the genera and species are provided. The chorionic eggs of eight genera and eight species were observed and shown using a scanning electron microscope.

Highlights

  • Heptageniidae is a family of mayflies with around 509 described species and distributed mainly in the Holoarctic, Oriental, and Afrotropical regions (Barber-James et al 2008). Wang and McCafferty (2004: Part I) “analyzed the generic relationships and presented a phylogenetic classification of the family” while Webb and McCafferty (2008: Part II) defined the genera providing an illustrated key

  • The total number of Thai Heptageniidae described to date amounts to 9 genera and 22 species

  • Studies of Thai heptageniid mayflies provide an important base on which to continue the study of these insects
