Abstract: Asian genera and species of the plant bug tribe Hallodapini are reviewed. The
present classification system is based particularly on detailed morphology and
function of the stridulatory device and concealed habitat preference. Our recent
efforts successfully demonstrated that the stridulatory devices of the forewing
edge and dorsal metafemur are doubtlessly used for intraspecific communication
(at least for courtship behavior). Based on the stridulatory structures and
additional characters, Cleotomiris Schuh, 1995, Cleotomiroides Schuh, 1984,
Hallodapus Fieber, 1858 and Wygomiris Schuh, 1984, are re-diagnosed and
discussed; Alloeomimella Yasunaga & Duwal gen. nov. is proposed to
accommodate Alloeomimus muiri Schuh, 1984 and a new combination, Alloeomimella
muiri (Schuh) comb. nov., is accordingly established. Six new species are
further described: Cleotomiroides ishikawachui Yasunaga & Duwal sp. nov.
(Indonesia: Java); Hallodapus jingfui Yasunaga & Duwal sp. nov. (Taiwan); H.
spinosus Yasunaga & Duwal sp. nov. (Thailand); H. susurratus Yasunaga &
Duwal sp. nov. (Thailand); Wygomiris paveli sp. nov. (Taiwan); and W. phormictes
sp. nov. (Taiwan). The male of Wygomiris nanae Yasunaga, 2012 is reported for
the first time. A teratological form found on the antennae in two Wygomiris
species is also documented.
