Further Data to the Knowledge of Tarsonemida (Acari) Living on Small Mammals in North America Dr. Sándor MAHUNKA Zoological Department of the Hungarian Natural History Museum, Budapest "Further data to the knowledge of Tarsonemida (Acari) living on small mammals in North-America" - Mahunka, S. - Parasit, Hung. 8. 85-94. 19.75. ABSTRACT. Tarsonemida mites collected on small mammals in Illinois, Indiana and Minnesota (USA) were identified. From 14 host species a total of 13 mité species were recorded of which 6 proved new to the science. The description of these species relegated to the genera Pygmephorus Kramer, 1877 and Bakerdania Sasa, 1961 is given. I have already reported, in a previous issue of this journal (2, 3), on some Pygmephorus Kramer, 187 7, species which had been coUected in the course of small mammal parasitological studies conducted at the Indiana State University, and which have been submitted to me for examination first by dr. J. O. WHJTAKER, Professor of the University, then by his collaborator, dr. J. O. SPICKA. Professor WHJTAKER has now supplied me again with a larger material for elaboration, the results of which are reported below. The present material contained not only species relegable to Pygmephorus Kramer, 1877, but also those of the genera Bakerdania Sasa, 1961, and Scutacarus Gros, 1845. Material referable to this latter genus wiU not be discussed now. Besides known Pygmephorus species a total of 6 new species, referable to Pygmephorus and Bakerdania were identified. Most new mite specimens were found on Microtus pinetorum (Le Conte), and some were obtained from Scalopus aquaticus (L. ), Cryptopis parva (Say), Condylura cristata (L. ), Blarina brevicauda (Say), and from Sorex trowbridgii Baird. In addition to Microtus pinetorum (Le Conte), the following host species have not yet been listed previously: Sorex cinereus Kerr Clethrionomys gapperi (Vigors) Sorex palustris Richardson Neurotrichus gibbsii (Baird) Sorex pacificus Cones Onychomys sp. Reithrodontomys megalotis (Baird) Tamias striatus (Linné) The hosts were collected in various localities, but about half of them was originated from a single locality. This latter one will be referred to in the descriptions by the following identification symbol: N. Am. 1 « Illinois, Clark Co. , 6 mil. NE, Marschall, from Microtus pinetorum (Le Conte). The holotypes of the new species are deposited in the United States National Museum, Washington (abbreviated: USNM), some of the paratypes in the same institution, in the Hungarian Natural History Museum (HNHM), under the inventory number listed per species, and in the Museum d'Histoire Naturelle, Geneve (MHNG). The numbers in brackets following the locality data represent the identification figures on the slides in dr. J. O. WHITAKER's collection. Pygmephoridae Pygmephorinae Pygmephorus designatus Mahunka, 1973 Locality: Indiana, Vermillion Co., Towa, 14 January, 1968. Host: Cryptotis parva. Leg. J. O. WHITAKER (No. 1829).
