Figs 64–69

Type locality. Huangmaolin Village , Yuanyang County, Honghe Prefecture, Yunnan, China .

Type material. Holotype: ♂, Huangmaolin Village , Yuanyang County, Honghe Prefecture, Yunnan, China, 14.VIII.2007, leg. Xue-Yan Li & Qin-Bai Hou ( KIZ) . Paratypes, one ♂, same data as holotype ( KIZ) (Lg18) .

Additional material examined. One ♀, Menglun Botanical Garden , Xishuangbanna Prefecture , Yunnan, China, 13.VIII.2015, leg. Xue-Yan Li & Zhi-Wei Dong (Lg17-F); One larva, Ailao Mountain , Xinping County, Yuxi City, Yunnan, China, V.2016, leg. Lu Qiu (Lg5-L) .

Diagnosis. This species has short oblong body (BW/BL approximate 0.63). It has large pronotum with brown ridges at margin and two transparent windows at the anterior top, and its pronotum is wider than elytra.

Description. Male ( Figs 64–66 ). Body short oblong. BL: 17.5 mm; BW: 11 mm; BW/BL approximate 0.63. Coloration ( Figs 64–66 ): head black; pronotum with the pentagonal pronotal disc black and other part light yellow; scutellum dark brown; elytra uniformly dark brown with light brown pilosity; legs with tibiae and tarsi brown to dark brown; abdominal ventrites I-V brown to dark brown, ventrites VI-VII yellow-brown. Head. Large because of big compound eyes; PW/GHW = 2.15; compound eyes kidney-shaped in lateral view and almost contiguous ventrally. 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, 3-10segments triangular, last antennomere bifurcate apically. Mandibles curved, slender and sharply pointed; maxillary palp 5-segmented, apical segment circular; labial palp bi-segmented. Thorax. Pronotum ( Fig. 66 ) semi-elliptical (PW/PL =1.91), surface clad with short, yellow-brown setae; widest at base; posterior margin flat; having two translucent windows only at the frontal edge, posterior angles rounded, wider than body width. Scutellum small, rhombus. Abdomen. Abdominal surface clad with short setae. Pygidium flat in the middle of posterior edge. Ventrite VII semi-circular.

(67–69).

Male genitalia ( Figs 67–69 ). Aedeagus sheath 1.84 mm long. Aedeagus 2.22 mm long, well-sclerotised. Basal piece oblong and smooth, shorter than parameres. Medial lobe uniformly strong, a little longer than parameres. Parameres strong, becoming gradually thicker from the bottom until 1/2, and then tapering from 1/2, with a sharply pointed end.

Females. According to pairwise nucleotide distances of COI, one female population from Manglu (Yunnan) ( Lg 17-F) (with a distance of 0.008 to type population) is identified as the same species .

Immatures. According to pairwise nucleotide distances of COI, one larval population from Xinping (Yunnan) ( Lg 5-L) (with a distance of 0.043 to type population) is identified as the same species .

Etymology. The species name magnapronotum is a combination of the Latin word magna meaning huge and pronotum, denoting its huge pronotum.

Distribution. China: Yunnan: Yuanyang, Mengla, Xinping.

Remarks. This species can be separated from nine species previously reported or newly described here based on type specimens ( L. minor , L. dorsalis , L. taimoshana , L. yunnana , L. lutosipennis , L. altcola , L. marussii , L. luquanensis ) or original description ( L. angustior ) ( Fairmaire, 1886; Pic, 1955) by its pronotum with two translucent windows only at the frontal edge with a costae between two windows and the remaining area dark brown ( Fig. 66 ). It can be separated from L. tenebrosa which has yellow brown elytra ( Fig. 22 ). It has dark brown femur, which can separate it from L. morator , L. nepalensis , L. nitidicollis , L. tardus with yellow brown femurs ( Figs 17, 20 , 26, 29 ). It has brown thoracic venters and ventrites I–VII, which can separate it from L. boyei with yellow venters ( Fig. 14 ). It can be separated from L. nitens ( Olivier, 1885) by the last two reddish ventrites of the latter. It has brown scutellum with round apex ( Fig. 64 ), which can be used to separate from L. scutatus (russet scutellum with narrow apex) ( Fairmaire, 1897b), L. crassus (pitchy scutellum) ( Gorham, 1880) and L. diffinis ( Figs 31 , 48 : scutellum with narrow apex).
