Hyalopsyche sachalinica Martynov

Hyalopsyche sachalinica Martynov 1910: 397 .

Hyalopsyche amurensis Martynov, 1934: 245 –246, f 178. Synonym according to Arefina et al. 1996: 10. Hyalopsyche parvispinosa Schmid 1959 ; 322, pl 2 f 6–7. New Synonym.

Hyalopsyche parvula Martynov 1935: 169 –170, 207, f 73a–c. New Synonym.

Material examined. VIETNAM: Hanoi, Song Hong, 17.i.1986, picked from the bare riparian zone of Red River [J. Oláh], 6 males, 4 females (OPC); Ngoclac, 25.i.1986, at light [J. Oláh], 1 male (OPC); Hoabinh, 12 km to Dabac, 30.i.1986, at light [J. Oláh], 2 males (OPC); Hanoi, La Tanh Hotel, 6.v.1987, at light [J. Oláh], 1 male (OPC).

Remarks. Schmid (1959) noted that H. parvispinosa Schmid is a possible synonym of either H. amurensis Martynov or H. parvula Martynov. The apex of the phallic apparatus has 1 pair of spines on the ventral lobe and 3–5 pairs of spines on the dorsal lobes of the aedeagus or endotheca. Arefina et al. (1996) synonymised H. amurensis Martynov with H. sachalinica Martynov due to identical genitalia. The drawings presented by Martynov (1910, 1934) and the drawings by Arefina et al. (1996) reflect the genitalia of the Vietnamese specimens.
