Drawida wuxiensis Qiao & Zhao sp. nov.Figs 1 - 4Material examined.Holotype: • one clitellate (CQWX 11_45) (COI accession number: PX 552887), Yintiaoling Nature Reserve (31.51855°N, 109.72814°E, 1942.72 m elev.), Wuxi County, Chongqing Municipality, 2025-05-11, coll. Huifeng Zhao. Paratypes: • six clitellates [CQWX 11_21 (COI accession number: PX 552882) CQWX 11_29 (COI accession number: PX 552883), CQWX 11_38 (COI accession number: PX 552884), CQWX 11_39 (COI accession number: PX 552885), CQWX 11_44 (COI accession number: PX 552886), CQWX 11_55 (COI accession number: PX 552888)], the six specimens share identical collection data with the holotype.Additional specimens.Four clitellates. CQWX 05_37 (COI accession number: PX 552881), Yintiao Ridge Nature Reserve (31.4681°N, 109.82181°E, 1244.22 m elev.) Wuxi County, Chongqing Municipality, 2025-05-09. CQWX 15_05, CQWX 15_06 (COI accession number: PX 552889, PX 552890, respectively) and CQWX 15_22 (COI accession number: PX 552891) Yintiao Ridge Nature Reserve (31.50869°N, 109.8618°E, 1178.47 m elev.), Wuxi County, Chongqing Municipality, 2025-05-14. All the specimens of the new species are deposited in the Hebei Key Laboratory of Animal Diversity, Langfang Normal University, Hebei, China (C-HLU).Diagnosis.Length 22.0–47.0 mm, diameter 3.0– 5.5 mm, 67–120 segments; body grey or white, head pale pink, clitellum light-pink to pale-yellow in X – XIII. Prostomium prolobous; dorsal pores absent. Setae four pairs per segment, aa = bc, ab = cd. Genital markings unpaired, irregular, VI / VII – XIII, maximum 4–7 papillae in XIII. Spermathecae paired in VII – VIII, ampulla white with slightly yellowish, comma-shaped or crescent-shaped in VIII, with a long, curly, tightly coiled duct, and atrium small oval shaped in VIII. Male pores paired, 10 / 11, between b and c, spindle-shaped, superficial, no penis. Female pores absent. Hearts 4 pairs (VI – IX). Septa 5–8 thick, muscular. Gizzards three, greyish-white with faint golden-caramel tint, XII (XIII) – XVIII (XX). The testis sacs are asymmetrically paired and pale brown or white, extending posteriorly from IX – XIII, occupying two or three segments; vas deferens slender, loosely coiled in IX – X; prostate glands one pair, elliptical, white, irregular-discoid, tightly adherent to parietes in XI. Ovisacs paired, umbrella handle-shaped, pink-tinged, XII – XIII, some extend to XV and XVI. Ovarian chamber absent. Accessory glands round, stalkless, corresponding to external genital papillae.Description.External characters: Length 22.0–47.0 mm, diameter 3.0– 5.5 mm, 67–120 segments. Head pale pink, body grey or white. Prostomium prolobous (Fig. 1 A, H). Dorsal pores absent. Clitellum annular in X – XIII, light pink or pale yellow (Fig. 1 B). Setae lumbricine, 4 pairs, small dots that exist in every segment except the first, about ab = cd, aa = bc. Genital markings present as small, white, papilla-like protuberances, unpaired irregularly in VI / VII – XIII. The highest number of papillae is typically observed in XIII of most specimens, with a range of 4–7. Spermathecal pore paired in 7 / 8 in bc-line, close to c. Male pores, paired in 10 / 11, between setae b and c, and the distances from b and c are approximately equal, spindle-shaped, superficial without protrusion or indentation, penis absent (Fig. 1 C, I). Female pores absent.Internal characters: Hearts four pairs in VI-IX. Septa V-VIII relatively thick and muscular, gizzards three in XII-XVIII or XIIII-XX segments, greyish-white with faint golden-caramel tints (Fig. 1 D, J). The testis sacs are asymmetrical paired and pale brown or white, extend posteriorly from IX – XIII, occupying two or three segments, vas deferens slender and loosely coiled in IX-X, with one pair elliptical white and Irregular disc-shaped prostate gland tightly adhered to the abdominal wall in XI (Fig. 1 E, K). Ovisacs paired, umbrella handle-shaped, tapering gradually toward the tip and pink-tinged, in XII-XIII, some extend to XV and XVI (Fig. 1 F, L). Ovarian chamber absent. Spermathecae paired in VII-VIII, ampulla white with slightly yellowish, comma-shaped or crescent-shaped in VIII, with long, curly, and tightly coiled duct, atrium small oval shaped in VIII (Fig. 1 G, M). Accessory glands round and stalkless, in correspondence with external genital markings.Etymology.The name refers to the type locality, Wuxi County in China.Distribution.Chongqing (China).Habitat.Grassland in high elevation in Chongqing Wuxi reserve.Remarks.DjSC currently includes D. calebi, D. companio, D. henanensis, D. japonica s. s., D. jeholensis, D. keikiensis, D. koreana, D. moriokaensis, D. siemsseni, D. sinensis, and the newly described species D. wuxiensis sp. nov. The new species exhibits a relatively short body length (22-47 mm), distinguishing it from D. koreana, D. siemsseni, D. keikiensis, D. calebi, D. jeholensis, D. moriokaensis and D. companio (Table 3). Additionally, D. wuxiensis sp. nov. displays a grey body color in alcohol, in contrast to the dark bule, buff and blotchy olive body color observed in D. koreana, D. siemsseni and D. impertusa (Hong 2002; Blakemore et al. 2014).Drawida wuxiensis sp. nov. most closely resembles D. henanensis, D. japonica s. s. and D. sinensis, but differs from D. henanensis by having three gizzards (vs two or three in D. henanensis), and the position of gizzards range from XII – XVIII or XIV – XX (vs XI / XII – XIII / XIV / XVI), by the comma-shaped spermathecae with a small oral atrium and long coiled duct (vs the round ampulla with an elliptical atrium of D. henanensis); it can be distinguished from D. japonica s. s. by its shorter length (22-47 mm vs 28-70 mm), the absence of female pores (present in intersegment 11 / 12 in D. japonica s. s.), and gizzards occupying segments XII – XVIII / XIV – XX (vs XI / XII – XIII / XIV in D. japonica s. s.); the new species differs from D. sinensis by the comma-shaped ampulla and tightly coiled ducts (vs ball-like ampulla and loosely coiled duct of D. sinensis). Additionally, the new species bears paired, elliptical prostate glands whose volume equals one-quarter that of the testis sac, whereas the ratio is 1: 3 in D. henanensis, 1: 2 in D. japonica s. s. and 3: 4 in D. sinensis.
