Abstract

COI sequences were used as an initial clustering method to delimit putative species of the genus Dudgeodes in the Philippines. An overview of the diagnostic characters of Philippine species and characters with high intraspecific variability are given. Six new species of Dudgeodes are described and illustrated: D. bauernfeindi Garces & Sartori, sp. nov., D. freitagi Garces & Sartori, sp. nov., D. luntian Garces & Sartori, sp. nov., D. pangantihoni Garces & Sartori, sp. nov., D. tabang Garces & Sartori, sp. nov., and D. vonrinteleni Garces & Sartori, sp. nov., all known from the nymphal stage. Supplementary descriptions are provided for D. pescadori Sartori, 2008, D. hutanis Sartori, 2008, D. stephani Sartori, 2008, D. ulmeri Sartori, 2008, and D. celebensis Sartori, 2008. A key to the nymphs of Philippine Dudgeodes species is proposed.

Keywords: Ephemerelloidea; Pannota; Luzon; Mindoro; Negros; Oriental Region.

Molecular species delimitation of Southeast Asian Dudgeodes using generalized mixed Yule coalescence (GMYC), Poisson Tree Processes (PTP) and multi-rate Poisson Tree Processes (mPTP) using partial COI sequence (593 bp). The phylogenetic tree shows the topology of COI gene tree following Maximum Likelihood method and Tamura 3-parameter+GI model, 1000 bootstrap. Only nodes with bootstrap > 70% are indicated. Statistical parsimony network of the new species and D. pescadori are given depicting the haplotype diversity and localities. Colors based on intra-Philippine biogeographic regions; black circles correspond to intermediate or missing haplotypes.
