Abstract: Species of the genus Acanthosoma Curtis, 1824 (Hemiptera: Heteroptera:
Acanthosomatidae) occurring in Taiwan are reviewed. Twelve species are
recognized, treated, and keyed. Four species (A. atayal sp. nov., A. axicia sp.
nov., A. fallax sp. nov. and A. pugnax sp. nov.) and one subspecies (A.
haemorrhoidale formosanum subsp. nov.) are described as new. Five species are
recorded for the first time from Taiwan: A. crassicaudum Jakovlev, 1880; A.
expansum Horváth, 1905; A. forficula Jakovlev, 1880; A. laevicorne Dallas,
1851; A. sichuanense (Liu, 1980). The records of A. forfex Dallas, 1851 and A.
rufescens Dallas, 1851 from Taiwan by previous authors are considered as
erroneous. Lectotypes are designated for A. expansum and A. laevicorne. The
Acanthosoma fauna of Taiwan is highly endemic; the zoogeographical affinities of
the species are briefly discussed
