Lamprophorus nepalensis Hope, 1831: 26 (Lampyris) (Type locality: Nepal; Assam plains, and Khasia hills, Gorh); Motshulsky 1854: 16 (? Diaphanes ); Lacordaire, 1857: 329; Gorham 1880: 89; Olivier 1885: 343.

Lamprigera nepalensis: McDermott 1966: 77 .

Lamprigera sp1 (genome size): Liu et al. 2017: 449–458.

Diagnosis. This species has short oblong body short oblong. Its ronotum has the centre black disc with other areas light brown. Its tibiae and tarsi of legs are black. It male genitalia has slender median lobe, slightly narrowed towards the apex in dorsal aspect, longer than parameres by 1/3.

Redescription of our male specimens ( Figs 82–84 ). Body short oblong. BL: 18.1–19.2 mm; BW: 8.3–9.0 mm; BW/BL: 0.47. Coloration ( Figs 82–84 ): head black; scutellum brown; elytra black; legs with tibiae and tarsi black; ventrites I–IV brown to dark brown, ventrites VI–VII light brown. Head. with large compound eyes, PW/GHW = 1.92–2; compound eyes kidney-shaped in lateral view and almost contiguous ventrally; interspace between eyes concave; antennae clavate, short, only slightly longer than the diameter of a compound eye, slightly exceeding the front edge of pronotum in transverse view, thickly hirsute, first antennomere cylindrical and as long as second, second narrower, 3–10segments triangular, last antennomere bifurcate apically; mandibles curved, slender, sharply pointed; maxillary palp 5–segmented, apical segment circular. Thorax. Pronotum ( Fig. 84 ) semi-circular (PW/PL = 1.52–1.68), with translucent trapezoid. Scutellum triangular. Elytra oblong, pilose.

Male genitalia ( Figs 85–87 ). Aedeagus sheath 1.54 mm long, covering dorsal side of male genitalia, with broadly rounded base. Aedeagus 2.3 mm long, strongly sclerotised, typically trilobate. Basal piece oblong and smooth, shorter than parameres. Median lobe slender, slightly narrowed towards the apex in dorsal aspect, longer than parameres by 1/3. Parameres rounded without protrusions, the base slightly narrower than the apex.

Females. Unknown.

Immatures. According to pairwise nucleotide distances of COI, two larval populations from Lancang (Lg16- L) and Yangbi (Lg9-L) (with a distance of 0.002 and 0.011 to Mengla male population (Lg-26), respectively) are identified as the same species.

Material examined. CHINA: Yunnan: 25 ♂, Xishuangbanna Tropical Botanical Garden, Mengla County, Xishuangbanna Prefecture, 24.XI.2016, leg. Xue-Yan Li & Gui-Chun Liu (Lg-26); Three larvae, Puer City, Lancang County , Yunnan, China, 4.VI.2005 (Lg16-L) ; 16 larvae, Dali City, Yangbi County, Maidi village , Yunnan, China, 6.VII.2007, leg. Xue-Yan Li (Lg9-L) .

Distribution. India: Nepal; China: Yunnan (Mengla, Lancang, Yangbi).

Remarks. By comparing with the type specimens ( Figs 19–21 , 44 ) and the original description ( Hope 1831), the specimens in this clade have the same morphology as L. nepalensis ( Hope 1831) , and thus are identified as such. This species is similar to L. morator in the shape of the pronotum ( Fig. 78 ), but its male genitalia ( Figs 85–87 ) can be separated from those of the latter ( Figs 79–81 ).
