Lamprigera minor ( Olivier, 1885)

Figs 70–75

Lamprophorus minor Olivier, 1885: 345 (Type locality: Burma).

Lamprigera minor: McDermott, 1966: 76 .

Diagnosis. This species has oblong body (BW/BL approximate 0.42), pronotum with central disc black and other areas yellow-brown, two transparent windows at the anterior edge; legs with tibae and tarsi brown; Male genitalia medial lobe strong, longer than parameres.

Redescription of our male specimens ( Figs 70–72 ). Body oblong. BL: 15.2–16.1 mm; BW: 6.2–7.1 mm; BW/ BL approximate 0.42. Coloration ( Figs 70–72 ): head black; pronotum with central disc black and other areas yellow-brown, two transparent windows at the anterior edge; elytra dark brown with light yellow fluff; scutellum dark brown; ventral side of thorax brown; legs with tibae and tarsi brown; ventral side with head, tibiae, tarsi, ventrites I–IV brown, and ventrites V–VII yellow-brown. Head. Large with big compound eyes, PW/GHW = 1.58–1.66; 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, slightly exceeding the front edge of the pronotum in transverse view, thickly hirsute, first antennomere cylindrical and as long as second, second narrower, 3-10 segments triangular, last antennomere flat. Mandibles curved, slender and sharply pointed; maxillary palp 5-segmented, apical segment circular; labial bi-segmented and pointed. Thorax. Pronotum ( Fig. 72 ) semi–elliptical (PW/PL = 1.53–1.63), with wide translucent edges and centrally round black disc. Scutellum small, triangular. Elytra oblong, basal disc strongly convex, with a lot of fluff.

Male genitalia ( Figs 73–75 ). Aedeagus sheath 1.15 mm long, covering dorsal side of male genitalia, with base broadly rounded. Aedeagus 1.38 mm long, heavily sclerotised. Basal piece oblong and smooth, shorter than parameres. Medial lobe strong, longer than parameres. Parameres symmetrical with their top weakly triangular.

Females. According to pairwise nucleotide distances of COI, one female population from Tengchong (Yunnan) (Lg10-F) (with a distance of 0.019 to the Yunnan male population (Lg11)) is identified as the same species.

Immatures. Unknown.

Material examined. CHINA: Yunnan: nine ♂, Yapingliuli, Lumadeng Village , Fugong County, Nujiang Prefecture , 1622 m, 15.VIII.2005, leg. Qin-Bai Hou (Lg11); Two ♀, Baoshan City, Tengchong County , Qushi, 21.X.2003, leg. Xue-Yan Li (Lg10–F) . Taiwan: Nine ♂, Shouka , Shizi Township , Pindong County, 430 m, 4.XII.2016, leg. Wen-I Chou (Lg27) .

Distribution. Burma; China: Taiwan (Pingdong), Yunnan (Fugong, Tengchong).

Remarks. By comparing with the type specimens ( Figs 4–6 , 39 ), we identified clade 4 ( Table 3) as L. minor , which was originally recorded in Burma ( Olivier 1885). This species is very similar to L. alticola ( Figs 52–57 ) and L. luquanensis ( Figs 58–63 ) but can be separated by having no dark brown area at the flanks of the semi-elliptical central black disc of pronotum in latter two. One of the populations was collected from Fugong (Lg11) bordering Burma. Although one male population was collected from Taiwan (Lg27), far from Yunnan, it has only a very small distance of nucleotide sequence (0.019); therefore, they are identified as the same species as the Yunnan population; the morphology is comparable with similar body and elytra shapes.
