Distribution.

This species appears to be rather restricted geographically, having so far been recorded only in the Chinese provinces of Fujian and Zhejiang ( Bezděk 2016; Krajcik 2011).

Material examined.

1♂: Coloane, Ká-Hó, 2 Jun 2019, on flowers of Syzigium buxifolium , R Perissinotto & L Clennell (SJCP).

Other Macau records.

Coloane, Ká-Hó, 29 May 2020, on flowers of Syzigium buxifolium , R Perissinotto [identification uncertain].

Remarks.

This is certainly the rarest cetoniine recorded so far in Macau, having been observed with certainty only once in June 2019, feeding on flowers of Syzigium buxifolium . A second potential specimen was observed in a nearby locality on the same flowers in May 2020, but its identification could not be conclusively verified as it was too far above the ground. According to S. Jákl (pers. comm.), this species is extremely rare throughout its limited distribution range and to our knowledge has not been reported from Hong Kong yet. The approximate size of the 2019 male specimen was 15 mm TL and 9 mm MW.
