                 , unnamed karst cave, 25.22388207°N, 110.24833740°E, 12.IV 2024, leg. native collector (ICJUST). 
            </p>
            <p>DESCRIPTION. MALE. Body elongated, cylindrical, apterous (Fig. 1). Head, pronotum, mesonotum, metanotum and abdominal tergites I-III dull, covered with dense short setae; remaining abdominal tergites and forceps polish, strongly punctured. Colour yellow to dark brown; head dark brown, with mouthparts and antennae yellowish brown; pronotum dark brown, with yellowish brown lateral margins; mesonotum dark brown, posteromedian portion yellowish brown; metanotum dark brown, central axis yellowish brown; abdominal tergites dark brown; femora mostly dark brown, basal parts yellowish; tibiae and tarsi yellowish; forceps reddish brown.</p>
            <p>Head flattened, much longer than wide, with post-ocular region weakly rounded (Fig. 1); caudal margin concave; post-ocular carinae weak; frontal suture invisible; coronal suture indistinct. Eyes small, about one-third the length of post-ocular region. Antennae 17 (+?) segmented; 1st segment much shorter than distance between antennal bases, nearly as long as 2nd to 4th combined; 2nd minute, near half of 3rd in length; 3rd much longer than 4th and slightly shorter than 5th segment.</p>
            <p>Pronotum much longer than wide, almost as wide as head (Fig. 1); lateral margins near parallel; posterior margin weakly sinuate medially; median longitudinal furrow indistinct. Mesonotum with posterior margin slightly concave, median longitudinal furrow indistinct. Metanotum with posterior margin strongly concave.</p>
            <p>Abdomen slightly expanded to tergite II, thence contracted to tergite V, thence gradually expanded to ultimate tergite (Fig. 1). Ultimate tergite with median longitudinal furrow distinct. Penultimate sternite strongly punctured; posterior margin broadly rounded, truncate medially (Figs 1–2).</p>
            <p>Forceps weakly curved upwards in lateral view (Fig. 2); basal one-quarter almost straight, with a row of small denticles extending from inner margin to upper inner margin; inner margin from basal one-quarter sinuate posteriad; apical one-third widened basally, inner margin dentate both dorsally and ventrally, with a thick-sliced upper tooth, thence with a series of teeth interspersed with minute denticles terminating before abruptly incurved apex.</p>
            <p>Genitalia are characterized by metaparamere narrow and long, weakly angulate apically, with a sclerotized, blunt inner process; genital lobe with conical formation covered with setae; virga sclerotized, long, slender, sinuous, apical portion expanded, covered with dense scales (Fig. 3).</p>
            <p>Female unknown.</p>
            <p>MEASUREMENTS. Holotype male: body length (from anterior of head to posterior of forceps) 20.9 mm; forceps length 5.6 mm.</p>
            <p> DIAGNOSIS. The new species differs from  C. fletcheri in the much longer head; the shape of forceps: inner margin of basal half almost straight (angled in  C. fletcheri ), apical one-third widened basally (unmodified in  C. fletcheri ), inner margin dentate both dorsally and ventrally (unmodified in  C. fletcheri ), with a thick-sliced upper tooth (absent in  C. fletcheri ); much simpler accessory structures (Nishikawa, 2006; Ho &amp; Nishikawa, 2009). It is easy recognizable from  C. kyusani in a simple, non-bifurcate inner process of metaparamere (Moon &amp; Kim, 1985). New species differs from  C. australis in the 3rd antennal segment much longer than 4th (subequal in  C. australis ); pronotum longer than wide (almost as long as wide in  C. australis ); the shape of forceps: basal one-quarter with small denticles extending from inner margin to upper inner margin, inner margin of apical one-third with a thick-sliced upper tooth (absent in  C. australis ) (Anisyutkin, 1994). It differs from  C. phoenix in the completely different body colour pattern; absence of sutures on head and thorax (distinct in  C. phoenix ); relatively shorter pronotum; the shape of forceps: apical one-third widened basally, inner margin dentate both dorsally and ventrally, with a thick-sliced upper tooth (with a subtriangular tooth in  C. phoenix ) (Anisyutkin &amp; Gorokhov, 1998). New species is easy recognizable from  C. taewooi in the much longer head; pronotum longer than wide (almost as long as wide in  C. taewooi ); posterior margin of penultimate sternite truncate medially (rounded in  C. taewooi ); apical one-third of forceps basally with a thick-sliced upper tooth (absent in  C. taewooi ); inner process of metaparamere distant from apex (near apex in  C. taewooi ) (Nishikawa, 2006). It differs from  C. imamurai in the much longer head; absence of sutures on head and thorax (distinct in  C. imamurai ); pronotum longer than wide (almost as long as wide in  C. imamurai ); posterior margin of penultimate sternite truncate medially (rounded in  C. imamurai ); the shape of forceps: widest near the middle (widest near apex in  C. imamurai ), apical one-third basally with a thick-sliced upper tooth (absent in  C. imamurai ); much longer genitalia with inner process of metaparamere distant from apex (near apex in  C. imamurai ) (Nishikawa, 2006). </p>
            <p> It differs from  C. gigantia in the much longer head; pronotum longer than wide (almost as long as wide in  C. gigantia ); the shape of forceps: thicker branches, widest near the middle (widest near apex in  C. gigantia ), apical one-third basally with a thick-sliced upper tooth (absent in  C. gigantia ); inner process of metaparamere distant from apex (near apex in  C. gigantia ) (Nishikawa, 2006 New species is easy recognizable from  C. hongkongensis in different body colour; the indistinct sutures on head and thorax (distinct in  C. hongkongensis ); apical one-third of forceps basally with a thick-sliced upper tooth (absent in  C. hongkongensis ); distal part of virga with different shapes (Ho &amp; Nishikawa, 2009). New species differs from  C. steineri completely different body colour pattern; the shape of forceps: apical one-third widened basally (unmodified in  C. steineri ), with a thick-sliced upper tooth (absent in  C. steineri ); genital lobes with conical formation covered with setae (absent in  C. steineri ); virga sinuous, apically expanded (virga heliciform, with simple apex in  C. steineri ) (Anisyutkin, 2020). </p>
            <p> REMARKS. The species was collected from a karst cave, but its dark body coloration and well-developed eyes suggest that it might not be a troglobiont, which is similar to the situation in  C. phoenix and  C. steineri (Anisyutkin, 2020) . </p>
            <p>DISTRIBUTION. The new species is known from Guangxi Zhuang Autonomous Region of China.</p>
            <p>ETYMOLOGY. The specific epithet refers to its type locality in Guilin City.</p>
