Figs 52–57

Type locality. Baishahe , Yulong County, Lijiang City, Yunnan, China .

Type material. Holotype: ♂, Baishahe , Yulong County, Lijiang City, Yunnan, China, 20.IX.2006, leg. Jia-Wei He ( KIZ) . Paratypes: 10 ♂, same data as holotype ( KIZ) .

Additional material examined. Five ♂, same data as holotype, partly damaged, one of them used for genomic DNA extraction (Lg12). Four larvae, Wumulong Township , Yongde County, Lincang City, Yunnan, China, 10.IX.2006, leg. De-cai Ouyang (Lg15-L), one specimen used for genomic DNA extraction .

Diagnosis. This species has a pronotum with translucent edge at its anterior and posterolateral sides and two expanded dark brown areas at the two flanks of semi-elliptical black central disc ( Fig. 54 ). The new species has ventrites I–V dark brown and ventrites VI–VII yellow-brown ( Fig. 53 ). The medial lobe of its male genitalia is only slightly constricted near apical 1/ 6 in dorsal aspect ( Figs. 55-57 ).

Description. Male ( Figs 52–57 ). Body oblong. BL: 15.2–16.2 mm; BW: 8–9 mm; BW/BL approximate 0.53– 0.55. Coloration ( Figs 52–54 ): head black; pronotal central disc black and its two flanks light brown, anterior edge and posterolateral sides translucent; scutellum yellow-brown; elytra black with uniform lustre and with posterior edge light brown; ventral side of thorax brown; legs black; ventrites I–V dark brown and ventrites VI–VII yellow-brown. Head. Large because of big compound eyes, PW/GHW = 1.75–1.83; compound eyes kidney-shaped in lateral view and almost contiguous ventrally, interspace between eyes concave. Antennae clavate, short, slightly longer than the diameter of a compound eye, a little exceeding the front edge of pronotum in transverse condition, thickly hirsute, first antennomere cylindrical and as long as second, second narrower, 3–10 segments triangular, last antennomere bifurcate apically. Mandibles curved, slender and sharply pointed; maxillary palp 5-segmented, apical segment blunt; labial palp bi-segmented and pointed. Thorax. Pronotum ( Fig. 54 ) semi-elliptical (PW/PL = 1.82–2.04), surface clad with short, yellow-brown setae; widest at base; posterior margin slightly protruded; having translucent edges and semi-elliptical black central disc, central disc convex. Scutellum small and strong triangle. Elytra oblong, basal disc strongly convex, with four longitudinal costae. Legs slender. Abdomen. Abdomen surface clad with short setae lateral angles of tergites acutely projected posteriad. Pygidium slightly concave in the middle of posterior edge. Ventrite VII semi-circular.

Male genitalia ( Figs 55–57 ). Aedeagus sheath 1.29 mm long, covering dorsal side of aedeagus, base broadly rounded.Aedeagus 1.99 mm long. Basal piece oblong and smooth, shorter than parameres. Medial lobe strong but narrower than parameres, slightly constricted near apical 1/ 6 in dorsal aspect. Parameres hypertrophic, about 2/3 as long as medial lobe and close to the medial lobe, distal edge sinuate, apex with a small protuberance and with hairs.

Females. Unknown.

Immatures. One larval population from Yongde (Lg15-L) may be the same species because it has a genetic distance of 0.071 to the type population, which is near the maximum distance (0.062) within different populations of Lamprigera ( Table 3).

Etymology. The species name is from the Latin alticola , referring to the distribution in mountains with high altitudes of more than 2000 m.

Distribution. China, Yunnan: Yulong (Lijiang), Yongde (Lincang).

Remarks. This new species can be distinguished from the 12 known species with type specimens checked in this study ( L. minor , L. dorsalis , L. boyei , L. morator , L. nepalensis , L. tenebrosa , L. nitidicollis , L. tardus , L. diffinis , L. yunnana , L. lutosipennis , L. marussii ) ( Figs 40–41, 43–51 ) by its a pronotum with a translucent edge along its anterior and posterolateral sides and two expanded dark brown areas at the two flanks of semi-elliptical black central disc. Considering that L. yunnana may be a junior synonym of L. angustior ( Jeng et al. 2000) , we think this new species can be separated from L. angustior , just as it is separated from L. yunnana . This new species can be distinguished from L. taimoshana by elytra with yellow edges ( Figs 10–12 ) and pronotum with wider translucent border ( Fig. 42 ) in the latter. We separated this new species from the remaining four known species based on their original description on color of ventrites. The new species has ventrites I–V dark brown and ventrites VI–VII yellow-brown ( Fig. 51 ), which can be separate it from L. nitens (ventrites VI–VII reddish) ( Olivier, 1885), L. scutatus (all ventrites russet) ( Fairmaire, 1897a) and L. crassus (all ventrites black) ( Gorham, 1880). This new species is also very similar to the populations of L. luquanensis newly described in this study, but can be separated from the latter by the flatter medial lobe of the male genitalia, and the medial lobe near 5/6 of its length being smooth in the former ( Figs 53–55 ).
