Humeral groove of elytra shallow, punctures of elytra diminishing posteriorly, absent on apical 1/3. Femora of legs without tooth. Lateral metasternum with a long and arcuate strip of pubescence.  Redescription. BL = 8.7-11.2 mm, BW = 3.0-4.5 mm. Bodybrownish red, head, antenna, legs and lateral metasternum with a blue metallic luster.  Head(Figs 15, 42A). Vertex flat, with a shallow groove in the middle, sparse punctate and pubescent laterally; frontoclypeal area triangular, lateral disc with sparse punctures and pubescent; labrum transverse, with sparse pubescent; antennae nearly 1/2 of body length, antennomeres 1-4 nearly globular, antennomere 2 shortest, antennomeres 5-10 nearly 1.5 xas long as wide, antennomere 11 slender.   Figures 15-18.Habitus of  Liliocerisspp. 15, 16  L. lianzhouensis, holotype, China (Guangdong), photographed by Yuan Xu 17, 18  L. rondoni, holotype, Laos (Sithandone), photographed by Jeremy Frank (BSM). Scale bars: 5.0 mm.  Pronotum(Figs 15, 42B). Anterior angles slightly protruding, posterior angles not protruding; sides constricted in the middle; disc slightly raised; middle of disc with two or four irregular rows of fine punctures.  Elytra(Figs 15, 32B). Humeri protruding, humeral groove and basal impression distinct; elytra without completely punctate striae, punctures large in the base, diminishing posteriorly, absent on apical 1/4; intervals smooth; epipleura raised, with a sparse row of fine punctures.   Mesosternum pubescent.Lateral metasternum with a long and arcuate strip of pubescence, extending from anterior margin to lateroposterior corner, metepisternum densely pubescent (Fig. 42A).  Abdominal sternite(Fig. 32A). Lateral transverse impressions big and distinct on sternites 1-4, other areas of sternite densely pubescent.  Leg(Fig. 32C). Femora with dense pubescence on the dorsal surface, nearly smooth on the ventral surface, without tooth.  Male genitalia(Fig. 52A-D). Ostium occupying 1/3 length of median lobe (Fig. 52A); apex crooked (Fig. 52B); tegmen Y-shaped, basal piece of tegmen triangular and broad, lateral lobes slightly sclerotized and combined with second connecting membrane; internal sac membranous, with distinct dorsal, median and ventral sclerites, dorsal sclerite wedge-shaped in dorsal view, ventral sclerite short and tubular (= flagellum), median sclerite small (Fig. 52C, D).  Female reproductive organs(Fig. 59A-C). Tergites 8 and 9 and sternites 8 and 9 sclerotized, posterior areas of tergite 8, sternite 8, and apodemes with pubescence, spiculum gastrale Y-shaped and long; ovipositor with dense pubescence, distal part of ovipositor cylindrical, long and with a protuberance; spermatheca simple and curved.  Distribution  (Fig. 68).China (Hunan, Yunnan, Guangxi, Guangdong, Hainan).  Host plant and habitat. Host plant is unknown. One collecting place, Hongkan Reservoir in Baisha, Hainan, is located in a subtropical area. The habitat is a lake area surrounded by primeval forests with high temperature and humidity.  Remarks. The species is similar to  L. jianfenglingensis, but differs by the antennomeres 5-10 nearly 1.8 xas long as wide, and brownish red with a blue metallic luster (Fig. 32D); the disc of the pronotum with two or four irregular rows of fine punctures (Fig. 42A); and the dorsal sclerite of the male genitalia is strongly sclerotized (Fig. 52C, D). In  L. jianfenglingensis, antennomeres 5-10 are almost as long as wide, and brownish red (Fig. 30D); the disc of the pronotum has two rows of fine punctures (Fig. 40B); and the ventral sclerite of male genitalia is weakly sclerotized (Fig. 54C, D). 2008-07-19 Yizhang, Mangshan Park, Ganyan Yang China 1339 24.95127 Nanling 1 112.98377 Total 19 1 Hunan 2021-06-27 Yong Wang China Mangshan Institute of Zoology 1 1 Hunan 2022-04-22 Neng Zhang China Shangxincheng Yuanyang 1 1 Yunnan 2018-05-23 Kaiqin Li China Huanglian Shan Lvchun 1 1 Yunnan 2011-05-20 Kaiqin Li China Daming Shan Nature Reserve Nanning 3 2 1 Guangxi 2011-05-27 Kaiqin Li China 1111 23.4996 Daming Shan Daxiagu 1 108.42891 Nanning 1 1 Guangxi 2011-05-29 Kaiqin Li China Institute of Zoology 1230 Daming Shan Nature Reserve Nanning 1 1 Guangxi 2006-08-03 Meiying Lin China Inst. of Zoology Huaping Longsheng 1 1 Guangxi 1979-04-16 1979-04-20 1979-04-16 Shaokun Du, Jinying Liang China Dinghu Shan 1 1 Guangdong 2018-07-19 Hongbin Liang, Yuan Xu China 5 22.82931 Dapeng 1 114.52472 Shenzhen 1 1 Guangdong 2009-11-24 Hongbin Liang China 525 19.08121 Hongkan Reservior 1 109.49839 Baisha 1 1 Hainan 1980-04-05 Qiongzhong, Wuzhi Shan, Fuji Pu China 800 Institute of Zoology 1 1 Hainan 2020-07-28 Yuan Xu China 886 19.04059 Gaofeng village 1 109.31583 Baisha 3 2 1 Hainan
