Abstract

The murine lice in Japan known untill May, 1955 were composed of nine species belonging to two genera; they were Polyplax spinulosa, P. serrata, P. abscisa, P. reclinata, Hoplopleura affinis, H. acanthopus, H. oenomydis, H. longula and H. intermedia. As for the hosts of these lice, ten species of rodents and Suncus murinus, which belonged to the family Soricidae, were recorded. Host-parasite relationships, records of specimens and brief differential descriptions, together with a key to these Japanese lice were given in this paper. Although the characters of paratergal plates were fairly different among the three groups of specimens collected each from Microtus montebelli, Eothenomys smithii smithii and Clethrionomys rufocanus bedfordiae, the author, for the time being, identified all these speicmens as Hoplopleura acanthopus. Hoplopleura oenomydis collected from Rattus rattus in Honson, Nijima-island, Honshu, provided with the very larger spiracles on paratergal plate than those of the specimens collected from other places in Japan. Hoplopleura akanezumi Sasa, 1950 was included in Haplopleura affinis in this report, because these two species related very closely in many respects except for the slight difference of convexity on the process of sternal plate. Pending problems described above will be cleared in future when the author is able to obtain more specimens.
