Laena moguntia n. sp. (Figs 9, 22)

Holotype (♂): N Vietnam, Tam Dao, 1.–8.VIII.1998, leg. N. Kanie, CKAO.

Etymology: Dedicated to the city of Mainz, the Roman Moguntium, where the author received his diploma and PhD at the Johannes Gutenberg University under the supervision of Prof. Dr. Jochen Martens.

Diagnosis: Laena moguntia n. sp. and Laena tamdaoensis Masumoto, 1996 from the same locality in Vietnam share the bigger body size, prominent eyes, crenulate lateral pronotal margins and dorsal structure and setation of the elytra, but can be separated by a rougher dorsal punctation with distinct impressions on the pronotum (compare Figs 9, 14), rounder shape of the elytra, the alternate intervals nearly keel­like (Figs 9, 14), the pair of distinct teeth on each femur (only a single tooth in Laena tamdaoensis), and the shape of the aedeagus (Figs 22, 25).

Description: Body length 7.0 mm. Eyes prominent. Pronotum (Fig. 9) with larger punctures, distance between 0.5–1 diameters, most punctures bearing long erect seta; surface with distinct mediobasal impression and a pair of distinct discal impressions, surface dull; lateral margin distinctly bordered, crenulate; propleura with finer, sparser punctation but similar setation. Elytra (Fig. 9) with complete rows of punctures without striae, equal in size to pronotal punctures, most in particular posteriorly bearing long, erect seta; intervals with a row of smaller punctures each bearing erect seta of same length, interval 9 with 6 distinct setiferous pores; intervals distinctly convex, alternate intervals 3, 5 and 7 much higher and nearly keel­like, surface shining. Femora with a pair of distinct identical teeth. Tibiae in males without distinct sexual character. Aedeagus see Fig. 22.
