THE MIRID SUBFAMILY CYLAPINAE (: ), OR FUNGAL INHABITING PLANT BUGS IN JAPAN

Yasunaga, T., 2000. The mirid subfamily Cylapinae (Heteroptera: Miridae), or fungal inhabit- ing plant bugs in Japan. – Tijdschrift voor Entomologie 143: 183-209, figs. 1-87. [ISSN 0040- 7496]. Published 1 December 2000. The plant bug subfamily Cylapinae of Japan is revised. This subfamily comprises species with a specialized biology, most of which are known to be associated with fungi. Sixteen species are recognized in six genera of three tribes. A new genus Yamatofulvius (type species Y. miyamotoi sp. n.) is proposed to accommodate three unique new species; its phylogeny is discussed. Eleven new species are described: Bothriomiris capillosus, Bothriomiris gotohi, Cylapomorpha michikoae, niveonotatus, hasegawai, Peritropis insularis, Peritropis iriomotensis, Peritropis takahashii, Yamatofulvius laevigatus, Yamatofulvius miyamotoi, Yamatofulvius sinuicornis. Ful- vius dimidiatus Poppius, F. tagalicus Poppius and Peritropis advena Kerzhner are reported from Japan for the first time. A key is provided to distinguish Japanese tribes, genera and species of the Cylapinae. The zoogeography of the Japanese Cylapinae is also discussed.
