( Figs. 4A View Fig , 5 View Fig , 8C View Fig )

Type-locality. China, Guangxi Province, Jinxiu County, Lianhuashan Mountain, 1100 m a.s.l., 24°09′21″N, 110°06′48″E.

Type material. HOLOTYPE: J, labeled ‘ CHINA: Guangxi Prov. / Jinxiu County / Lianhuashan Mt. / 30.vii.2011, 1100 m / Jia-Yao Hu leg. // HOLOTYPE (red) / Linan fortunatus / sp. n., Yin & Li / det. 2012, SNUC’.

Diagnosis. Reddish brown; medium-sized; postgenae rounded; antennomeres IX–XI enlarged and modified; pronotum with lateral margins rounded basolaterally; pronotal and elytral basolateral margins with tufts of dense setae; with long metaventral processes; metatrochanter protuberant; aedeagus with asymmetric median lobe.

Description. Male ( Fig. 4A View Fig ). Length 2.51. Head slightly longer than wide, HL 0.60, HW 0.57; eyes each composed of about 30 facets. Antennal club as in Fig. 5A View Fig . Pronotum ( Fig. 5B View Fig ) about as long as wide, PL 0.58, PW 0.59, with round lateral margins. Elytra wider than long, EL 0.71, EW 1.02. Metaventral processes long, pointed apically ( Fig. 5C View Fig ). Protibiae with indistinct apical spur ( Fig. 5D View Fig ), protrochanters and profemora simple ( Fig. 5E View Fig ), mesotrochanters ( Fig. 5F View Fig ) with short and blunt triangular ventral protuberance, metatrochanters ( Fig. 5G View Fig ) with short truncate ventral protuberance curled. Abdomen large, AL 0.62, AW 1.01. Sternite IX as in Fig. 5H View Fig . Aedeagus length 0.46; with apically asymmetric median lobe ( Figs. 5I–K View Fig ).

Female. Unknown.

Comparative notes. The species is placed as a member of the L. cardialis group (speciesgroups defined in YIN et al. 2011). It shares with L. huapingensis sp. nov. (described below) and L. megalobus Yin & Li, 2011 the long metaventral process not being apically bifurcate. The tuft of dense setae at the pronotal and elytral basolateral margins of L. fortunatus sp. nov. separates the species from all other members of the L. cardialis group.

Etymology. The species name reflects the joyfulness when the single male was discovered.

Biology. The individual was collected by sifting leaf litter along a path at mid-altitude of the mountain ( Fig. 8C View Fig ).

Distribution. South China: Guangxi.
