Lamprigera luquanensis Dong & Li , sp. nov.

Figs 58–63

Type locality. Dazhichang , Xueshan Township , Luquan County, Kunming City, Yunnan, China .

Type material. Holotype: ♂, Dazhichang , Xueshan Township , Luquan County, Kunming City, 23.IX.2006 leg. Zi-Chao Liu ( KIZ) . Paratypes, three ♂ same data as holotype ( KIZ) .

Additional material examined. Four ♂, same data as holotype, partly damaged, one of them used for genomic DNA extraction (Lg2). Three larvae, Yunzhong Lake , Jiugong Mountain, Tongshan County, Hubei, China, 3.VIII.2016, leg. Li-Xin Jiang (Lg20) .

Diagnosis. This species has translucent edges at its anterior and laterally posterolateral sides and two expanded dark brown areas at the two flanks of semi-elliptical black central disc. Its medial lobe shows an obvious constriction near apical 1/6 and the two parameres a little flatter than those of L. alticola ( Figs 61–63 ).

Description. Male ( Figs 58–63 ). Body oblong. BL: 16.7–18.5 mm; BW: 6.5–7.9 mm; BW/BL 0.39–0.43. Coloration ( Figs 58–60 ): head black; pronotal disc black and its two flanks light brown, anterior edge and posterolateral sides translucent ( Fig. 60 ); prosternum and mesosternum black with pale yellow margin; scutellum pale brown; elytra black with light brown posterior edge; thorax pale brown; legs with coxa of femurs pale brown, tibiae and tarsi black; ventrites I–V black, ventrites VI–VII light brown. Head. Large because of big compound eyes, PW/GHW = 1.83–1.90; 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 frontal edge of pronotum in transverse view, 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 circular; labial pointed bi-segmented. Thorax. Pronotum ( Fig. 60 ) semi-elliptical (PW/PL = 1.69–1.90), surface clad with short, yellow-brown setae; widest at base; posterior margin flat; having translucent edge and black central disc, central disc convex. Elytra oblong, hairless. Abdomen. Abdomen surface clad with short setae. Pygidium slightly concave in the middle of posterior edge. Ventrite VII semi-circular.

Male genitalia ( Figs 61–63 ). Aedeagus sheath 1.53 mm long, covering dorsal side of male genitalia, with base broadly rounded. Aedeagus 2.35 mm long, well sclerotised. Basal piece oblong and smooth, shorter than parameres. Medial lobe strong and slightly narrowed towards the apex in dorsal view, longer and narrower than parameres. Parameres with the apex slightly wider than the base, gradually separated from medial lobe, distal portion flat with a small protrusion.

Females. Unknown.

Immatures. According to pairwise nucleotide distances of COI, one larval population from Hubei province (Lg20-L) (with a distance of 0.025 to the type population) is identified as the same species.

Etymology. It is named for Luquan County where the type was collected.

Distribution. China: Yunnan: Luquan; Hubei: Tongshan.

Remarks. This new species is very similar in outer morphology to L. alticola above described. Thus, like L. alticola above described, the new species can be distinguished all known species via similar diagnosis. This species is further separated from L. alticola by its medial lobe of male genitalia which is more constricted near 5/6 of the apex and by its parameres being a little flatter ( Figs 61–63 ). According to pairwise nucleotide distances of COI, the Lamprigera population from GenBank (accession number KX758087.1) (with a distance of 0.019 to the type population) is identified as the same species.
