DISTRIBUTION. Russia: Khabarovsk Territory, Sakhalin, Kurile Islands (Iturup, Kunashir: Map 9, Shikotan). — Japan (Hokkaido).
BIONOMICS. This is a very common species in Kunashir Island. Specimens were collected on stony and occasionally on sandy banks of streams and rivers, and sometimes near thermal zones (Figs 9–12). It was found in a stony shore in the caldera of Goryacheye Lake (Fig. 9).
REMARKS. Liophilydrodes puncticollis has a relatively variably shaped pronotum with fine to moderately coarse punctation, indistinct to distinct microsculpture between punctures both on head and pronotum, and markedly transverse or somewhat elongate elytra. Habitus as in Fig. 6. The width and shape of the apical portion of the median lobe and parameres are subject to little variation (Figs 21–26). The internal sac of the genus Liophilydrodes is here presented for the first time: L. puncticollis has a relatively complex and variable shape of it (compare Figs 22, 24–26 and Figs 21, 23). Liophilydrodes puncticollis is recorded from Kunashir and Shikotan islands, and from the mainland Asia (Russia, Khabarovsk Territory) for the first time.
In general, the genus Liophilydrodes is in need of a taxonomic revision and comparative morphological study of the variability of the body and aedeagus. This could eventually lead to new synonymies of some names from Japan, which are apparently more widely distributed. It is worth noting that L. subtilis iturupensis, described based on one female from Iturup Island [Lafer, 2004], in some details of the body differs from two syntypes of Anthophagus subtilis Sharp, 1889, deposited in BMNH and known to the senior author. However, a study of additional material from the type locality and other adjacent islands is required for the clarification of its taxonomic status.
