Leafhoppers of the genus Macropsis Lewis, 1836 (Homoptera: Auchenorrhyncha: Cicadellidae: Macropsinae) on Sakhalin - different evolutionary trends in different species Tishechkin, D. Yu. Russian Entomological Journal 2019 2019-09-30 28 2 107 119   5.  Macropsis hinganensisTishetshkin, 2004  Figs 39–47, 107–118, 154–159. COLORATION. Males from Sakhalinusually 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 Kraionly green or brownish specimens were found ( Figs 45–47). MALE ABDOMINAL APODEMES AND PENIS. Abdominal apodemes of 2 ndtergite 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 capreaL., occasionally, also  S. taraikensisKimuraon Sakhalin;  S. bebbianaSarg.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. Theshape of syllables changes gradually from the beginning to the end of a phrase. Theinitial syllables include 1–2 or no gaps, whereas the end syllables are separated by 3–4 gaps each ( Figs 155–156). Signalsof 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 typelocality, 5 kmNorth from Obluchye Town towards Khingansk, South-western part of Khabarovsk Krai; was not found on  Salixsect.  Vetrixin other regions of the Russian Far East. Was fairly abundant on Sakhalinon its host plants on dry glades, roadsides, and in other open habitats.  REMARKS. Coloration of specimens from Sakhalinis 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. MALE, CALLING, SIGNAL The -2.5 Signals The 7 114 1 Sakhalin
