Abstract
Epidamaeus hexatuberculatus sp. n. (Oribatida: Damaeidae) is described from Russia. The new species is similar to E. nortoni Bayartogtokh, 2004 and E. tritylos Behan-Pelletier et Norton, 1983 but differs from both by the absence of enantiophyses E2 and V, the presence of mediosejugal enantiophysis, narrowly phylliform interlamellar seta and tubercle-like, rounded distally discidium, and the localization of prodorsobasal tubercle Da.
Highlights
The oribatid mite genus Epidamaeus was proposed by Bulanova-Zachvatkina (1957) with Oribata bituberculata Kulczynski, 1902 as type species
The genus comprises about 80 named species, collectively distributed mostly in the Holarctic region, but with some representation in the Neotropical and Oriental regions (Subías 2004, online version 2021; Norton & Ermilov 2021)
The identification keys to some species of Epidamaeus were presented by Bulanova-Zachvatkina (1975), Miko (2006), Bayartogtokh (2010) and Norton & Ermilov (2021)
Summary
The oribatid mite genus Epidamaeus was proposed by Bulanova-Zachvatkina (1957) with Oribata bituberculata Kulczynski, 1902 as type species. The genus comprises about 80 named species, collectively distributed mostly in the Holarctic region, but with some representation in the Neotropical and Oriental regions (Subías 2004, online version 2021; Norton & Ermilov 2021). The generic traits were summarized and discussed by Bulanova-Zachvatkina (1957, 1975), Miko (2006) and Norton & Ermilov (2021). The identification keys to some species of Epidamaeus were presented by Bulanova-Zachvatkina (1975), Miko (2006), Bayartogtokh (2010) and Norton & Ermilov (2021). During taxonomic identification of Epidamaeus from the Russian Western Siberia, we found one new species. The main goal of this paper is to describe and illustrate this species
