Five New Species of Mites in the Genus Leptogamasus Trägårdh, 1936, and a New Subgenus Medioperigamasus (parasitiformes: Parasitidae)

Five new species of mites belonging to the genus Leptogamasus are described, in a new subgenus Leptogamasus (Medioperigamasus)—L. (M.) lamelligynus sp. nov., L. (M.) parcus sp. nov., L. (M.) ramosus sp. nov., L. (M.) sarcidanus sp. nov. and L. (M.) sasha sp. nov. A key to adults of all 12 globally known species of subgenera Breviperigamasus and Medioperigamasus is proposed.
