摘要
现已知我国复套蛞蝓科,复套蛞蝓属共计6种,主要分布于我国台湾、广东、海南、浙江、广西、上海、安徽、四川等省市以及香港、澳门等地区。作者在云南省玉溪地区峨山彝族自治县采得复套蛞蝓科一新种:玉溪复套蛞蝓Vaginulus yuxiensis。本文对该新种的外部形态和内部构造,尤其对生殖系统和齿舌的形态结构作了较详细的描述,其齿式为:(3:1:3)/152。并且作者与其近似种中国复套蛞蝓 Vaginulus chinensis Moellendorrf,1881;和佛尔复套蛞蝓 Vaginulus fargcsianus Heude,1885进行了比较。
In the present paper, a new species of the family Veronicellidae ( = Vaginulidae) Blain-ville, 1817 is described. The materials studied were collected by the authors from Yi Autonomous County (24°25’N, 102°30’E) of Eshan, Yuxi Prefecture, Yunnan Province, China, in 1986. Type specimens are deposited in the Institute of Zoology, Academia Sinica, Beijing.Vaginulus yuxiensis, sp. nov. (figs. 1 - 6)Holotype: Length after alcoholic immersion 46.7 mm, diameter 19.1 mm; Huanian, Yi Autonomous County of Eshan (24°25’N, 102°30’E), Yuxi Prefecture, Yunnan Province, China, Nov. 1986.Paratypes: 19 specimens, length after alcoholic immersion 32.5 - 48.1mm.; diameter 10.2 -21.3 mm; Huanian, Yi Autonomous County of Eshan (24°25’N, 102°30’E), Yuxi Prefecture, Yunnan Province, China, Nov. 1986.Body medium-sized, flat, rough, light brown or yellowish brown in colour. Mantle covering the whole dorsum, not corrugated, but with many granule and black spots, without any protrusions and yellowish brown bands. Sole yellowish, with 3 longitudinal bands, and central band deep yellowish brown in colour, grooves, lateral bands smooth, sole of tail and mantle dissociated. Tentacles dark brown in colour. Female respiratory orifice in the middle of right side of the sole; Male respiratory orifice in the rear of right tentacle. Penial slender cylinder-form, with structure of honeycomb-form in the top of the penial, and with draw muscle. Seminal vesicle cylinder-form. Jaw yellowish brown, with many ribs, shoes-form. Radula with about 152 rows of teeth, each with 1 central tooth, 48 lateral teeth, but no external marginal tooth.This new species resembles very closely Vaginulus chinensis, Moellendorff, 1881 and Va-ginulus fargesianus, Heudc, 1885, but differs from the latters in the small size, in the mantlewithout any protrusions and yellowish brown bands, and in the penial slender cylinder-form,with structure of honeycomb-form, in the radula with 1 central tooth, 48 lateral teeth, but nofxternal marginal tooth.
