References: Candèze 1885, 1891; Schwarz 1906; Schenkling 1925; Fleutiaux 1926; Van Zwaluvenburg 1936; Suzuki 2001, 2011.

Material examined: Indonesia: Sumatra Isl ., Bengkulu, 05.2019; (1 male, local collector leg.). The habitus as in Fig. 1 , and the aedeagus as in Fig. 2 .

General distribution: Indonesia: Sumatra and Nias islands.

Remarks. Oxynopterus harmseni was originally described in 1885 from Indonesia, Sumatra, pay des Battaks ( Candèze 1885). After that, it was mentioned only twice in the scientific literature (except catalogues or check­lists). It was firstly recorded 116 years after the original description ( Suzuki 2001, 2011). The Table 1 shows the published data on the representation of the species in the collections, the number of specimens, sex and published records.

Regarding the occurrence of O. harmseni in world collections, currently only four specimens of this species (three males, one female) are available in the scientific literature, of which data on one male is presented in the present study. It is probably a very rare species whose biology and ecology are still unknown. Perhaps this species is in danger and needs real protection. Faunistic studies in Sumatra are needed to clarify the distribution and population status of this species .
