5. Macropsis hinganensis Tishetshkin, 2004

Figs 39–47 , 107–118, 154–159.

COLORATION. Males from Sakhalin usually green or brownish with strongly darkened forewings ( Figs 39–40 ), occasionally, pale yellow with two brown longitudinal stripes on head, pro-, and mesonotum and with brown basal halves of the forewings ( Fig. 41 ). Females green with transparent forewings ( Fig. 42 ) or yellow with brown pattern ( Figs 43– 44 ); dark pigmentation in yellow females varies much more widely than in males.

In the population from Khabarovsk Krai only green or brownish specimens were found ( Figs 45–47 ).

MALE ABDOMINAL APODEMES AND PENIS. Abdominal apodemes of 2 nd tergite rather narrow, sometimes slightly bent inwards, separated by wide notch (Figs 107– 108). Sternal apodemes triangular, with narrow tips, broadly separated by more or less rectangular notch (Figs 109–110). Penis slender, with almost parallel margins in side view (Figs 111–112). Males from Sakhalin (Figs 107–112) and the mainland (Figs 113–118) are similar in the shape of apodemes and penis.

HOST PLANTS. Salix caprea L., occasionally, also S. taraikensis Kimura on Sakhalin; S. bebbiana Sarg. in Khabarovsk Krai (all belong to the section Vetrix ).

MALE CALLING SIGNAL. Calling signal is a single phrase increasing in amplitude towards the end and lasting from 5–6 to 15–20 s ( Fig. 154 ). It consists of syllables following each other with a period of ca. 1.5– 2.5 s. The shape of syllables changes gradually from the beginning to the end of a phrase. The initial syllables include 1–2 or no gaps, whereas the end syllables are separated by 3–4 gaps each ( Figs 155–156 ). Signals of males from Sakhalin ( Figs 154– 156 ) and from the mainland ( Figs 157–159 ) are similar .

RANGE. Very rare species in the mainland, until now was known only from the type locality, 5 km North from Obluchye Town towards Khingansk, South-western part of Khabarovsk Krai; was not found on Salix sect. Vetrix in other regions of the Russian Far East. Was fairly abundant on Sakhalin on its host plants on dry glades, roadsides, and in other open habitats.

REMARKS. Coloration of specimens from Sakhalin is much more variable than in the only known population from the mainland. In morphological and acoustic traits no significant differences between the mainland and insular populations were found.
