Type material: Holotype: CHINA Yunnan: male ( SYSU), CHINA : Yunnan Prov., Jingdong / County , Ailaoshan Nature / Reserve, 24°32′N 101°01′E / 2484m, 12-14.iv.2015 / Renchao Lin & Yudan / Tang leg [transcribed from Chinese]. Paratypes (17 specs., KMNH, NMPC, NMW, SUSU, APC): CHINA GoogleMaps : Yunnan: 7 specs, same data as holotype . Sichuan: 10 specs, CHINA: W-Sichuan / Ya’an Pref., Shimian Co. / Xiaoxiang Ling , Pass betw. / Shimian-Ganluo , 27km SE / Shimian, 2450m, springfed- / swamp, 29.02.75 N, 102.31.48E/ 8.VII.1999, leg. A. Pütz .
Diagnosis. Body obovate. Head and pronotum without impression and microsculpture ( Figs. 13, 17 View FIGURES 10 – 17 ). Anterior margin of labrum bearing a transverse row of setae. Pronotal punctures uneven, denser laterally than mesally. Ground punctures on elytra rather coarse, ten rows of large punctures present on posterior half of elytra ( Figs. 10, 12 View FIGURES 10 – 17 ). Mesoventrite flat. Meso- and metafemora pubescent on basal four-fifths ( Fig. 60 View FIGURES 56 – 62 ). Parameres with lateral incisions subbasally and subapically, widening in midlength, apex weakly projecting laterally. Apex of median lobe situated ca. apical ninth of paramere in length ( Fig. 51 View FIGURES 50 – 55 ).
This species is very similar to C. aduncata and C. obovata . Ground punctures on elytra of C. lianggeqiui are generally coarser than C. aduncata and C. obovata ; reliable identification requires a careful examination of the male genitalia. Genital morphology is similar to that of C. obovata : apex of median lobe is situated subapically in the species ( Fig. 51 View FIGURES 50 – 55 ), whereas that of C. obovata is situated in apical fourth ( Fig. 23 View FIGURES 18 – 23 ).
Description. Length 3.5–3.9 mm, width 2.1–2.4 mm. Body obovate, attenuating posteriorly, convex ( Fig. 10 View FIGURES 10 – 17 ). Color. Dorsal surface black to dark reddish brown, pronotum somewhat reddish brown, lateral margins of pronotum yellowish brown ( Fig. 13 View FIGURES 10 – 17 ). Maxillary and labial palps and antennae uniformly yellowish brown, with infuscate antennal club. Ventral surface dark reddish brown, legs usually dark brown ( Fig. 11 View FIGURES 10 – 17 ).
Head. Labrum densely punctate, with broadly emarginate anterior margin; anterior margin of labrum bearing a row of setae densely distributed. Clypeus truncate anteriorly, with dense punctures ( Fig. 13 View FIGURES 10 – 17 ) coarser than those on labrum. Frontoclypeal suture indistinct. Punctures slightly denser on frons than on clypeus. Eyes slightly protruding. Mentum transverse, ca. 2 × as wide as long, with fine punctures, shagreened, without impression; anterior margin of mentum as wide as posterior margin, truncate ( Fig. 61 View FIGURES 56 – 62 ). Labial palpomere 3 asymmetrical, as long as the penultimate. Maxillary palpomere 4 ca. 2 × as long as palpomere 3. Antenna with nine antennomeres, club almost as long as antennomeres 2 to 6 combined ( Fig. 62 View FIGURES 56 – 62 ). Gula narrow, subparallel, gular suture slightly curved medially.
Thorax. Pronotum evenly convex, without impressions and systematic punctures ( Fig. 13 View FIGURES 10 – 17 ); ground punctures on pronotum sparser than those on frons mesally, denser and coarser laterally than mesally; intervals smooth, microsculpture absent. Lateral and anterior margins of pronotum weakly beaded ( Fig. 12, 17 View FIGURES 10 – 17 ), anterior margin clearly bisinuate, posterior margin weakly bisinuate, lateral margin evenly curved. Elytra attenuating posteriorly, systematic punctures absent. Ground punctures on elytra rather coarse; ten rows of large serial punctures present posteriorly ( Fig. 10 View FIGURES 10 – 17 ), lateral two rows strongly impressed, reaching anterior quarter ( Fig. 12 View FIGURES 10 – 17 ). Sutural stria almost reaching anterior quarter, deeply impressed ( Fig. 10 View FIGURES 10 – 17 ). Prosternum flat ( Fig. 14 View FIGURES 10 – 17 ), anterior margin broadly protruding. Mesoventrite flat. Metaventrite covered with distinctly pubescence, bulging medially, with a small glabrous area ( Fig. 15 View FIGURES 10 – 17 ). Meso- and metafemoral pubescence on basal four-fifth ( Figs. 11, 15, 16 View FIGURES 10 – 17 , 60 View FIGURES 56 – 62 ).
Abdomen. Abdominal ventrites densely pubescent. First ventrite not carinate. Apical margin of fifth ventrite rounded ( Fig. 16 View FIGURES 10 – 17 ). Aedeagus. Paramere with outer margin deeply incised subbasally, then inflated apical to incision; apex weakly projecting laterally. Median lobe rounded apically, apex situated in ca. apical ninth of paramere ( Fig. 51 View FIGURES 50 – 55 ). Manubrium long, apex rounded.
Etymology. This species is named after professor Ge-qiu Liang, a retired orthopterist at Sun Yat-sen University. He was the first author’s (FJ) supervisor when FJ worked for his Master’s degree twenty-five years ago.
Biology. Aquatic. The type locality is a small pond with some grass in it and covered with some bamboo leaves; the pond is surrounded by bamboo ( Fig. 74 View FIGURES 73 – 74 ).
Distribution. China (Yunnan, Sichuan).
