崇安湍蛙分类厘定与中国西南部一新种描述,以及山湍蛙种组讨论与湍蛙属种组划分整理

Taxonomic revision of Amolops chunganensis (Pope, 1929) (Amphibia: Anura) and description of a new species from southwestern China, with discussion on Amolops monticola group and assignment of species groups of the genus Amolops

  • 摘要: 崇安湍蛙为复合种,广泛分布于中国东部、南部和西南部。该文依据崇安湍蛙复合种19个种群的分子数据,包括模式产地武夷山种群,厘定了狭义崇安湍蛙,并提供了依据地模标本的补充描述。结合形态与分子数据,该文描述中国西南部一新种——钊琴湍蛙Amolops chaochin sp. nov. ,该新种曾经被鉴定为崇安湍蛙。新种具有以下鉴别特征可与山湍蛙种组其他物种相区分:(1)体型中等,雄性体长35.3−39.2 mm(n=7),雌性体长50.5−54.4 mm(n=7);(2)鼓膜清晰,鼓膜径大于眼径之半;(3)下颌前端中央具有一个小的齿状突;(4)指缘均具边缘沟;(5)雄性和雌性的体背部后方具白色疣粒;(6)雄性和雌性股背面具清晰有,胫背面具白色刺状疣粒;(7)雄性鼓膜后方具白色疣粒;(8)第二趾内侧的蹼以缘膜达吸盘;(9)具犁骨齿;(10)四肢背面具横纹;(11)雄性具外声囊。该文还对湍蛙属的种组划分进行整理,厘定了各种组的物种成员及鉴别特征。

     

    Abstract: Amolops chunganensis is a species complex and reported widely from eastern, southern, and southwestern China. Based on molecular data of 19 populations of A. chunganensis sensu lato from China, including the population from Mt. Wuyi (type locality), we recognize A. chunganensis sensu stricto and provide an expanded description based on the topotypic specimens. Combining morphological and molecular data, we describe a new species, Amolops chaochin sp. nov. , from southwestern China, which was previously identified as A. chunganensis. The new species is distinguished from all other species in the A. monticola group by: (1) moderate body size, SVL 35.3−39.2 mm in males (n=7), and 50.5−54.4 mm in females (n=7); (2) distinct tympanum, larger than half of eye diameter; (3) small tooth-like projection on anteromedial edge of mandible; (4) circummarginal groove on all fingers; (5) white tubercles on dorsal side of posterior body in both sexes; (6) distinct tubercles on dorsal thigh and white spinose tubercles on dorsal tibia in both sexes; (7) white tubercles on posterior region of tympanum in males; (8) toe webbing reaching disk by dermal fringe on inner side of toe II; (9) vomerine teeth present; (10) transverse bands on dorsal limbs; (11) external vocal sacs present in males. We further reviewed the assignment of Amolops groups, with an overall revision of membership and diagnosis of all species groups.
