Abstract

The currently recognized Ephemerella species are included in 13 subgenera. New subgenera are Cincticostella and Acerella. Ephemerella levanidovi Tshernova is transferred to Cincticostella n. subg., thus it contains six species, E. nigra Ueno n. comb., E. castanea n. sp., E. delicata n. sp., E. imanishii n. sp., E. insolta n. sp., and E. levanidovae Tshernova n. comb. The subgenus Acerella n. subg. includes four species, E. longicaudata Ueno n. comb., E. commodema n. sp., E. perculta n. sp., and E. undatella n. sp., Ephemerella yoshinoensis Gose is transferred to the subgenus Drunella and four undescribed and unnamed species, E. kohnoi n. sp., E. aculea n. sp., E. hifurcata n. sp., and E. borakensis n. sp., are placed in Drunella. Three undescribed species, E. denticula n. sp., E. keijoensis n. sp., and E. maxima n. sp., are included in the subgenus Ephemerella s. s.
