Map 17 .

Eusphalerum prope hidakanum Watanabe, 1990 : Zanetti, 1993

MATERIAL: 2 ♂♂, 1 ♀: Ivanovskiy Cape , Grozovoye natural boundary , 43°50´28´´N 145°24´29´´E, 02– 04.06.2013, Yu.N. Sundukov, L.A. Sundukova leg. ( CS) ; 1 ♀: Ivanovskiy Cape , 08– 21.09.2014, Yu.N. Sundukov ( CS) ; 1 ♀: same data, Grozovoye , 43°50´28´´N 145°24´29´´E, 08– 09.07.2013, Yu.N. Sundukov, L.A. Sundukova leg. ( CS) .

REMARKS. The aedeagus of the examined males is similar to the illustrations provided in Figs 27–28 in Zanetti [1993]. The shape of apical portion of the median lobe resembles that of E. hidakanum Watanabe, 1990 , which was described from Hokkaido (Mt. Daisetsu), Japan. A study of type material is necessary for reliable identification.
