Laena jocheni n. sp. ( Figs 4 View FIGURES 1 – 8 , 18 View FIGURES 17 – 26 )

Holotype (♂): NE Laos, Hua Phan Prov., Ban Saluei, Mt. Phu Phan, 2000 m, 26.IV.–11.V.2001, leg. J. Bezdek, SMNS.

Paratypes: NE Laos, Hua Phan Prov., Ban Saluei, Mt. Phu Phan, 1500–1700 m, 30.IV.2002, leg. N. Ohbayasi, 1 ex. CKAO. – NE Laos, Hua Phan Prov., Mt. Phu Phan, 1700–1800 m, 28.–30.III.2005, leg. K. Ando, 1 ex. CKAO. – NE Laos, Hua Phan Prov., Ban Saluei, Mt. Phu Phan, 11.–13.IV.2004, leg. N. Ohbayasi, 1 ex. CKAO. – NE Laos, Hua Phan Prov., Ban Saluei, Mt. Phu Phan, 1500–2000 m, 26.IV.–11.V.2001, leg. D. Hauck, 1 ex. SMNS. – NE Laos, Hua Phan Prov., Mt. Phu Phan, 28.IV.–6.V.2002, leg. H. Yoshitomi, 1 ex. CKAO.

Etymology: Dedicated to Prof. Dr. Jochen Martens (Mainz) on the occasion of his 65th birthday (not to be mixed with the previously dedicated Laena martensi Kaszab, 1973 from the Nepal Himalayas).

Diagnosis: Laena jocheni n. sp. is quite similar to Laena acco Masumoto, 1996 from northern Vietnam, but can be separated mainly by the shape of the pronotum (lateral margin rounded, widest shortly before the middle, bordered in Laena acco , lateral margin straight, widest near anterior angles, unbordered in Laena jocheni n. sp.) The chaetotaxie of the elytral setiferous pores is also somewhat different ( Laena acco : interval 3 basally with 1 pore, interval 7 without pore, interval 9 with 3 pores), however this characters might be variable. The aedeagi can not be compared because Laena acco is known only by the female holotype.

Description: Body length 5.3–7.0 mm. Eyes prominent. Pronotum ( Fig. 4 View FIGURES 1 – 8 ) with large punctures, distance between 1–3 diameters, most punctures bearing short adpressed seta; surface flat, shining; lateral margin unbordered; propleura with similar punctation, without setation. Elytra ( Fig. 4 View FIGURES 1 – 8 ) with complete rows of punctures without striae, punctures equal in size to pronotal punctures, without seta; intervals without punctures and setae, humeral area of interval 7 with setiferous pore, interval 9 with 4 setiferous pores; all intervals slightly convex, shining. Femora in both sexes without distinct tooth or other modification. Tibiae in males without distinct sexual character. Aedeagus see Fig. 18 View FIGURES 17 – 26 .

Remarks: The type locality Mt. Phu Phan in Laos is situated about 250 km from Mt. Phang Si Pang (Fan Si Pan) in northern Vietnam, where Laena acco and other congeners have been described.
