Integrative taxonomy of the genus Dudgeodes Sartori, 2008 (Insecta, Ephemeroptera, Teloganodidae) from the Philippines with description of new species and supplementary descriptions of Southeast Asian species

COI sequences were used as an initial clustering method to delimit putative species of the genus in the Philippines. An overview of the diagnostic characters of Philippine species and characters with high intraspecific variability are given. Six new species of are described and illustrated: Garces & Sartori, , Garces & Sartori, , Garces & Sartori, , Garces & Sartori, , Garces & Sartori, , and Garces & Sartori, , all known from the nymphal stage. Supplementary descriptions are provided for Sartori, 2008, Sartori, 2008, Sartori, 2008, Sartori, 2008, and Sartori, 2008. A key to the nymphs of Philippine species is proposed.
