(Figs. 201–202, 226–230)

Types. Holotype: ♀, 1300–1400m, Huanglianshan , Luchun, Yunnan, China, 6.IX.2016, George Ho Wai-Chun ( HKES) ; Paratype: 1♀, 1300–1400m, Huanglianshan , Luchun, Yunnan, China, 7.IX.2016, George Ho Wai-Chun ( HKES) .

Diagnosis. Carausius huanglianshanensis sp. nov. [ China (Yunnan)] is similar to C. novus sp. nov. [ China (Yunnan)], but can be separated by robust body, large size, carina-like praeopercular organ on seventh abdominal sternum and strongly raised median longitudinal carina on posterior portion of abdominal subgenital plate.

Description. Female (Figs. 201–202, 226–230). Large size. General colouration of body and legs brown. Body elongate and very slender, surface rough, with sparse granulations.

Head: Oval, longer than wide, constricted after compound eyes. Rough, sparsely covered with small granules. Vertex with a U-shaped crest between compound eyes. Occiput convex, median and lateral longitudinal furrows indistinct, posterior margin with six small swellings. Compound eyes small and rounded. Antennae filiform, reaching apices of protibiae; scapus dorsoventrally flattened, constricted basally, longer than third segment; pedicellus shorter than third segment.

Thorax: Rough, wrinkled and sparsely granulated. Pronotum rectangular, anterior margin curved inwards, posterior margin rounded, transverse and longitudinal sulci crossing just after middle area. Mesonotum longer than combined length of metanotum and median segment, with very faint median longitudinal line. Metanotum longer than median segment.

Abdomen: Cylindrical, rough and wrinkled, also covered with sparse and small granules. Median segment rectangular, two times longer than wide, longer than pronotum. Second tergum as long as third tergum. Third to fifth tergites equal in length, longer than second tergum. Fourth tergum lacking or with a hump on anterior area. Sixth tergum with a hump on posterior area. Seventh sternum with carina-like praeopercular organ posteromedially. Eighth tergum longer than ninth tergum, with a small black spot near lateral margins. Anal segment longer than ninth tergum, posterior margin with a broad emargination. Supra-anal plate small, posterior margin rounded, with median longitudinal carina, posterior margin projecting over posterolateral angles of anal segment. Subgenital plate boat-shaped, median longitudinal carina strongly raised after middle area, also with short tubercles and granules situated at posterior half. Cerci short and obtuse, apices not projecting over end of anal segment.

Legs: Profemora basally curved, shorter than mesonotum, anterodorsal carina distinctly waved with eight to ten small rounded elevations, posteroventral carina raised. Protibiae shorter than profemora, posterodorsal carina strongly raised and waved. First segment of protarsi with a small semi-circular lamella dorsally. Posteroventral carina of mesofemora and metafemora with two small spines near apices.

Male. Unknown.
