Idiocerus apicalis Matsumura, 1912: 323- Huang and Maldonado-Capriles 1992: 4 (listed); Xue et al. 2017: 407 (listed).

Remarks.

This species was described from a single female specimen (holotype) from Taiwan. Both Andy Hamilton and Masami Hayashi (pers. comm.) examined the type (Entomological Institute, Hokkaido University, Sapporo, Japan) and the latter’s photographs of the type are reproduced here (Fig. 5A, B). The holotype bears a determination label by Andy Hamilton indicating the species belongs to Balocerus but this needs to be confirmed, particularly as the specimen is female. The label information on the specimen is as follows (hw = handwritten, pr = printed):

I. apicalis sp. nov. (hw), det. Matsumura (pr)

Formosa, Matsumura (printed), (underside) Toroen, 19/4 '07 (hw)

Holotype (red label, printed), Idiocerus apicalis Matsumura (hw)

Balocerus apicalis (Matsum.), Det. KGAH '76 (hw; label with red frame)
