[New SJN: Kunashiri-hae-himebachi]

( Figs. 6A–C View Fig , 22K View Fig )

Eusterinx (Divinatrix) kurilensis Humala, 2004: 67 View in CoL .

Diagnosis. Antenna of male with tyloids from FL VI to FL VIII (sometimes weak in FL VIII). Inner eye orbit strongly convergent ventrally ( Fig. 6B View Fig ). Occipital carina complete. T II and T III each divided into two parts by a transverse groove ( Fig. 6C View Fig ). Propodeum without a pair of spine-like apophyses ( Figs. 6A, C View Fig ). Fore wing with an areolet. T I 2.75–2.9 times as long as maximum width, without conspicuous median dorsal carina except for base. Posterior parts of T II and T III covered with longitudinal striae, which similar to the anterior part (or slightly weaker than anterior part in T III) ( Figs. 6C View Fig , 22K View Fig ). T IV with a conspicuous transverse groove, its posterior part usually covered with longitudinal striae ( Figs. 6C View Fig , 22K View Fig ). Hind coxa more or less darkened ( Figs. 6A, C View Fig ).

Distribution. Japan (Kunashiri Is., Hokkaido and Honshu), Far East Russia and Korea ( Yu et al., 2016; Humala et al., 2017).

Remarks. This is the first record of this species from Hokkaido. Longitudinal striation of posterior parts of T III and T IV is sometimes reduced in Japanese specimens.
