NEW RECORDS OF SOME RARE MAYFLIES (INSECTA, EPHEMEROPTERA) FROM UKRAINE

Palingenia fuliginosa (Georgi, 1802) and Isonychia ignota (Walker, 1853) are reliably recorded in Ukraine for the first time. New localities where larvae of Brachycercus harrisella Curtis, 1834, Siphlonurus aestivalis Eaton, 1903 and Metreletus balcanicus (Ulmer, 1920) develop in Ukraine were registered. Baetopus ( Raptobaetopus ) tenellus (Albarda, 1878) is given for Ukraine for the first time. Investigated microhabitats of these species are shortly described. Main factors influencing the abundance of P. fuliginosa in detected habitats are discussed. Isonychia ignota , P. fuliginosa and M. balcanicus are recommended to be included in the next edition of the Red Data Book of Ukraine.
