【摘要】 探讨并殖吸虫螺类宿主自然资源。发现采自福建北部的沼蜷属螺Paludomus一新种,命名为闽北沼蜷。参照《医学贝类学》和相关文献进行形态描述。正模(FJ6135)壳高18.15 mm,壳宽13.46 mm,壳口高14.05 mm,壳口宽8.04 mm。产地武夷山九曲溪。螺层5层,顶层及原壳层多缺失,螺面呈绿褐色,各螺层宽度上向体螺层增长迅速,体螺层大而膨胀,其高度上约占全部高度的4/5。齿舌中央齿呈尖峰状,中部支齿大而突出。内缘齿单支而宽大,两侧缘各有3或5枚不甚突出小齿,分布不对称,排列公式:3-1-3,3-1-5(3),7,5。本新种可与黔沼蜷(P.quianensis Liu et al,1994)、带沼蜷(P.cinctus Liu et al,1994)比较鉴别。更多还原

【Abstract】 The authors reported a new species of Paludomus from the northern part of Fujian province,named as the northern part of Min.With reference to"medical malacology"and related literature to conduct morphological description,the new species was holotype(FJ6315),with a height of 18.15 mm,width of 13.46 mm,height of aperture of 14.05 mm,and width of aperture of 8.04 mm.The new species has an origin in Wuyi Mountain Jiuqu Creek.It has a height of 16.25(14.83–19.01)mm,width of 10.20(9.14–12.90)mm,height of 10.64(9.60–12.56)mm,and width of 7.01(5.89–8.38)mm.The species had five convex whorls.Most of its apex and the original shell were missing,and the species was increasing rapidly with a large and inflated body whorl of about 4/5 the height of shell.Its central radula was spiked,the central branch radula was big and prominent,the inner edge radula was single and wide,each having 3 or 5 non-prominent teeth at both sides of the edge,asymmetry.Radula formula:3-1-3,3-1-5(3),7,5 which identified with Semisulcospira libertina,Paludomus qianensis(P.quianensis Liu et al,1994)and Paludomus cinctus(P.cinctus Liu et al,1994)更多还原
