Three new species of Harpellales from Mount Tsukuba

ABSTRACT

Three new species of Harpellales, collected on Mt. Tsukuba, Kanto Plain on Honshu Island, are described. Stachylina philoricola, derived from midgut of Philorus sp. (Blephariceridae: Diptera), and Lancisporomyces tsukubaensis, derived from the hindgut of Amphinemura sp. (Nemouridae: Plecoptera) nymphs, are described. Blephariceridae is newly added to the host insect families of Harpellales. A new genus, Zygopolaropsis, is proposed to accommodate the new species Z. sphaerica, derived from the hindgut of Baetis thermicus (Baetidae, Ephemeroptera) nymphs.
