Distribution: Taiwan ( Heller 1931).

Remark: Heller (1931) did not designate a primary type or specify the number of specimens being examined in the original description. However, it is apparent that his description was based on multiple specimens from a single locality “...— Kosempo.”. He also indicated that these specimens were deposited in SNSD and SDEI. There are four such specimens in the SNSD and five in the SDEI, indicating that all nine specimens are syntypes with equal nomenclatural status. To establish a definitive, name-bearing type for C. (M.) formosanus , we designate the male syntype labeled as “type!”, which closely matches the original description, as the lectotype of C. (M.) formosanus . The other specimens from the type series are thus designated as paralectotypes.
