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.
