2. Macropsis suspecta Tishetshkin, 1994

Figs 7–21, 66–78, 132–141. COLORATION. In this species, coloration is extremely variable (Figs 7–21). Many local populations have unique combinations of colour variations and some rare variations are known from only one or two localities. The studied population from South Sakhalin (Figs 7–14) is characterized by a considerable proportion of variations with black pronotum (Figs 8, 11, and 13), which are very rare in the mainland. However, the

presence of these variations in the sample from the environs of Sokol Town on Sakhalin is not a proof of differences between the mainland and insular populations in general .

MALE ABDOMINAL APODEMES AND PENIS. In the shape of male 2 nd abdominal apodemes and penis is similar to the previous species (Figs 66–78).

HOST PLANTS. Populus laurifolia Lebeb. and P. suaveolens Fischer in Siberia; P. maximowiczii A. Henry in the Russian Far East including Sakhalin.

MALE CALLING SIGNAL. In males from Sakhalin short ( Figs 132–133 ) and complex ( Figs 136–138 ) forms of calling signal were recorded. Short form of the signal in M. suspecta is similar to that in M. fuscinervis ( Figs 128–131 and 132–135 ). Complex signal is a phrase consisting of several different parts ( Figs. 136–141 ); it differs from the complex signal of M. fuscinervis by the presence of additional components at the beginning of a phrase [for details see Tishechkin, 1999]. Temporal patterns of signals of both types in males from Sakhalin ( Figs 132–133 and 136–138 ) and the mainland ( Figs 134–135 and 139–141 ) are identical.

RANGE. South-eastern Kazakhstan, Siberia, Northern Mongolia, and the Russian Far East. Was introduced to Kyrgyzstan (northern shore of the Issyk-Kul’ Lake) with cultivated P. laurifolia and Populus sp.

REMARKS. In morphological and acoustic traits, no significant differences between the mainland and insular populations were found.
