The paper describes a new species of ground beetles ( Coleoptera: Carabidae), Notiophilus solodovnikovi sp., collected on the Sahalin islands, in the south of the Russian Far East. Special diagnostic indications are given, which are comparable to those of N.aquaticus (L.). The difference from the latter anyhow, lies in the distinctly punctured outer rows of dots, running nearly to the middle, more parallel elytra sides, the widest part of which is behind the middle, and not at the top of elytra, more convex aedeagus , and other indica tions.

INTRODUCTION Asian Notiophilus Dumeril, 1806 (Coleoptera: Carabidae) ground beetles are not completely stud ied. Which were recently described by O.Križanovskis (Kryzhanovskij, 1995). Before that, only 6 species: N. aquaticus (Linnaeus, 1758); N. borealis Harold, 1869;N. breviusculus Solsky, 1872; N. sibiricus Motschulsky, 1844; N. impressifrons A.Moravitz, 1862; N. reitteri Spaeth, 1899, had been mentioned for the Rusian Far East; among them, only 3 species: N. aquaticus (L.), N. impressifrons Mor.; N. reitteri Spaeth, were met on the Sahalin island (Lafer, 1989; Kryzhanovskij etal., 1995; Barševskis, 1999). In case of N. reitteri Spaeth, every elytra has a lingitudinal red-brown apical spot, the front part of which is narrowed, and the back part, near the top, is nearly as wide as the elytra itself. In case of N. aquaticus (L.), N. impressifrons Mor, their elytras have no longitudinal lines. Both species are obviously different: the front part of the clypeus in N. impressifrons Mor is bilobular, very much convex in the middle. According to the division of Notiophilus Dum.into sub-genera (Barševskis, 1994, 1999), N.
reitteri Spaeth belongs to the sub-genus Latviaphilus Bars., and both belong to the sub-genus Notiophilus (s.sts.). In general, speaking about the division of Notiophilus Dum. Into sub-genera, it seems necessary to point out that its inner system is incomplete, being not enough worked out. Many entomologists look at it as a whole, not divided into sub-genera. The author (Barševskis, 1994) has attepted to divide it into 3 sub-genera: Notiophilus (s.str.), Latviaphilus Bars., 1994, and Makarovius (Barševskis, 1994). This di vision is also adopted in the check list of ground bee tles of Russia and neighbouring countries (Kryzhanovskij etal, 1995). The division is also used in the analysis of distribution peculiarities of Northand East-European Notiophilus Dum. (Barševskis, 1997, 1999). The check list of all known ground bee tles in the world (Lorenz, 1998) is not in favour of the above mentioned division of Notiophilus Dum.into sub-genera. While describing new species, and discussing theit place in the genus system, the author relies, for the monent, on the division of Notiophilus Dum.into sub-gen era which he had presented earlier.

In this paper, the description of a new Notiophilus Dum species, N. solodovnikovi BarUewskis, sp.n., from Sahalin in the Russian Far East, was described basing on one male specimen. Relatively distinct differences from the only more or less similar species N. aquaticus (L.), and lack of more materials, which results from the fact that the fauna of the Sahalin island has not been studied enough, made it possible to describe the new species having only one specimen. Inspite of the fact that the legs of the available specimen are not unicolour black as would be typical for N. aquaticus (L.), the presence of very distinct puncture pattern on the rows of elytras, quite special form of elytra, and a number of other indications, this species is the closest to N. aquaticus (L.).

Notiophilus solodovnikovi Barševskis sp.n. Holotype. Male Russia: Far East, Sahalin isl.,S., Chehova Mnt., 12.08.1995. Ivanovskij leg. Presented in the collection of the Baltic Institute of Cleopterology (Fig. 1). Description. The body is black with a metallic shine. The upper part is bronze-black, brightly shining. Legs have two colours: coxa and femora are black with a very bright metallic shine, tibia are fire-red, glossy. The head has 6 nearly parallel keels, the inner pair of which are close to each othe in the base. The front part of the upper lip is practically straight, not concave. The first four antennomeres of the antennae are fire-yelIow. Elytras are nearly parallel, with only slightly convex edges, but behind shoulders they are practi-

cally not concave.They reach their widest outside the middle. The rows of dots on the elytras have large imprinted marks; their diameter is no less than a third of the distance between the rows. The rows of dots on the sides are nearly as distinct as dorsal. The outer side rows are irregulas at the base, with random dots. The 4,h dorsal interval has a pore at the base. At the end of elytra, there is a sub-apical pore, which is hardly seen among distinct rows of dots. Elytra surface is smooth, has no microsculpture, which appears only at the end of elytra. Elytra is obviously bent down. The shield of the front part of the breast pronotum has S-bent side edges and protruded posterior angles, which are shart and make a narrow angle. Punctur pattern of the shield is quite rough, and in some places it turns into plicated lines. Full body length: 4,6 mm. Female spesimen is unknown.
N.
solodovnikovi Barevskis, sp.n. (Fig.l).
Elytra is more parallel to sides, behind shoulders there is practically no curve, reaches its widest behind the middle. Rows of dots are more distinct, there are rough dots, which become only slightly weaker towards the top. Rows of outer side elytra are, at least at the middle, as much developed as the dorsal. At the top, elytra has a more dramatic fall Body is slender and finer, more bronze shine. Shield of the front part of breast has angles which are more protruded to the sides, sharp and narrow.
Male Genitalia structure: aedeagus is very much convex; parameras are less developed than in N. aquaticus (L.), they are smaller, thinner, and narrower (Fig- 3).
Legs are two-coloured: black femora and fire-red tibiae
Etymology. The species is named after Igor Solodovnikov, entomologist from Republic of Belarus.
Peculiar mail genitalia: aedeagus is strongly convex, endophallus has a wider fine brush or line, paramera are less developed, smaller, thinner, ans narrower.
First 4 parts of antaennae are fawn-coloured.
Comparison. The species is similar to N. aquaticus (L.)

edge is slightly widened, the widest here.
Rows of dots are less distinct, the dots are smaller, hardly seen towards the top, already at the fall of elytra. Rows of outer side elytra are less developed than the dorsal. At the top, elytra has a slanting fall. Body is heavier, less bronze shine. Shield of the front part of breast has nearly right angles which are only slightly protruded. Legs are usually inucolor black, specimens with two-coloured legs are rare, while tibia are partly fire-red. First 4 parts of antaennae are dark-brown on the outer surface, and brown on the inner surface. Peculiar mail genitalia: aedeagus is slightly convex, endophallus has a shirter fine brush or line, parameras are more developed, bigger, thicker, and wider.
Didtribution. Not clear The genus is represented by only one male specimen, found on the Sahalin is land.
