Ochthebius (Asiobates) lurugossus Jäch, 1998 – Zinchenko, 2014: 202 ( Russia: Primorskii krai, near Kaimanovka village)

Ochthebius (Homalochthebius) minimus (Fabricius, 1792): Shatrovskij, 1989: 263 (mis-

identification).

DESCRIPTION. Length 1.95 мм. General appearance as in Fig. 2 . Body dark green, with rufous tint; antennae, palpae and legs dark brown. Labrum transverse, with notched distal margin. Apical palpomere three times shorter than penultimate ones. Head surface covered with short semi-erect hairs. Forehead-clypeal suture arch-shaped and extremely deeply depressed. Forehead shining and deeply canaliculate at its sides. Eyes large, well-developed.

Pronotum transverse, 1.6 times wider that long, surface bare. Anterior margin straight;

lateral sides extremely archly narrowed at their basal halves. Hyaline membrane developed.

Disc surface and sides glabrous, with double punturation, sparse strong punctures with small punctures amongst them. Median groove complete and not deep.

Elytra oval, semi-shining, strongly convex, separately rounded at apex. Five rows of punctures noticeable on disc between suture and humerus. The rows straight, with strong chaetophorous pores deeply depressed and densely located. Intervals of rows narrower than puncture diameter. Lateral grooves extremely narrow. Pseudo-epipleurae wide anteriorly and evenly narrowed posteriorly, not reaching elytral apexes.

Aedeagus ( Figs 7, 8 ; see also Jäch, 1990: 84, Fig. 14c and Jäch, 1998: 176, Fig. 3 ), main lobe irregularly curved, distal lobe with large apical tube, upturned distally. Lateral sclerite directed upwards and forward. Parameres widely moved apart from basal part, weakly curved,

not reaching 2/3 of the length of the main lobe of the aedeagus.

NOTES. The species was first mentioned for the Russian Far East by A.G. Shatrovskij

(1989), but it was misidentified as Ochthebius (Homalochthebius) minimus (Fabricius, 1792)

and the distribution for this species was reported as the Russian Far East. Zinchenko (2014)

was the first author who provided an exact locality for this species in Russia: Kaimanovka,

Ussuri District.

DISTRIBUTION. North-Eastern China (Heilongjiang: Harbin); the Russian Far East

(Primorskii krai).
