A cladistic insight into the higher level classification of Baetidae (Insecta: Ephemeroptera)

Abstract

Baetidae was one of the first families established for mayflies (Ephemeroptera). After more than 200 years of progressive research, Baetidae is now known as the most species‐rich family in the order. Two competing proposals of family division were proposed: Cloeoninae and Baetinae, or Protopatellata and Anteropatellata. Both classifications were established without cladistic support. The purpose of this paper is to investigate the phylogenetic relationships of the family Baetidae using morphological evidence and evaluate these classification schemes. The matrix included 245 morphological characters derived from larval and adult stages across 164 species in 98 genera. The resulting tree recovered Anteropatellata, Protopatellata and Cloeoninae as not monophyletic; Baetinae and Baetovectata were recovered as monophyletic with the same circumscription. Subimaginal and imaginal characters presented the lowest homoplastic values and were the best to understand the higher relationships.

Philibaetis gen. nov., a new genus from the Philippines (Ephemeroptera, Baetidae)

“…The family Baetidae has the highest species diversity amongst mayflies, comprising ca. 1,100 species in 114 genera (Sartori and Brittain 2015, Jacobus et al 2019, Cruz et al 2020, Kluge 2020, which is close to one third of all mayfly species worldwide. They have a cosmopolitan distribution, except in Antarctica and New Zealand.…”

Contribution to the knowledge of the genus Takobia Novikova & Kluge, 1987 (Ephemeroptera, Baetidae) in Central Asia

“…Some subsequent authors used Takobia sensu Kluge and Novikova (2014) as a subgenus of Nigrobaetis (e.g., Martynov and Godunko 2017;Bojková et al 2018). However, the synonymy of Alainites with Takobia was not generally followed and accepted, therefore many authors continued to use the genus Alainites (e.g., Gattolliat et al 2015;Fujitani et al 2017;Cruz et al 2020). It is important to note that none of the proposals for the systematic treatment of the taxa mentioned above were based on cladistic analyses.…”

“…The family Baetidae has the highest species diversity amongst mayflies, comprising ca. 1,100 species in 114 genera (updated from Sartori and Brittain 2015, Jacobus et al 2019, Cruz et al 2020, which is approximately one third of all mayfly species worldwide. They have a cosmopolitan distribution, except for New Zealand (Gattolliat and Nieto 2009).…”
