Leptotrombidium suzukii (Acari, Trombiculidae): A New Species of Chigger Mite Found on Apodemus speciosus (Rodentia, Muridae) on Nakanoshima Island in the Tokara Islands, Kagoshima Prefecture, Japan

摘要

We describe a new species, Leptotrombidium suzukii (Acari, Trombiculidae), of Chigger mites. The type material is laboratory-reared unfed larval trombiculid mites (F6 generation) that developed from the fully engorged larvae collected from Apodemus speciosus (Temminck, 1844) from Nakanoshima Island in the Tokara Islands, Kagoshima Prefecture, Japan. The new species is closely related to Leptotrombidium bunaense (Womersley, 1952), n. comb., n. stat. [=Leptotrombidium (Leptotrombidium) bunaense Vercammen-Grandjean and Langston, 1976, a new junior synonym and homonym of Trombicula deliensis form bunaensis Womersley, 1952], but it is distinguished by the arrangement of the dorsal setae and long scutal setae.
