Remarks.

This species was first recorded from Northeastern China (Manchuria) by Plavilstshikov (1936). Gressitt (1951) cited this information and added Zhejiang (Tianmushan) as a new locality, which was the first misidentification. Then, Chen et al. (1959) followed Gressitt (1951) and made a drawing based on specimens from Tianmushan, which misled subsequent Chinese longicornists to misidentify Distenia orientalis sp. n. as Distenia gracilis. Therefore, the record from Zhejiang and Jiangxi is incorrect, as it was based on misidentification of Distenia orientalis sp. n. The records from Hubei and Anhui are doubtful and may also be based on misidentification of Distenia orientalis sp. n. (or another species) but we did not have specimens available from these two provinces. Chou (2004) didn’t include Distenia gracilis in his book on Taiwanese fauna. Records of Distenia gracilis from Japan were based on misidentification of Distenia japonica.

We did not have specimens from Korea for study. We consider the record by Ganglbauer (1887) and Lee (1987) correct based on the pictures by Lee (1987).

The holotype of Apheles gracilis Blessig, 1872 is a male from Russia, Sibérie (Amurland), collected by P. Wulffius. It was supposed to be deposited in ZMAS. We could not reach the curators in ZMAS. According to personal communication by Mikhail Danilevsky, he could not find the type in the collection of ZMAS.
