The status of species currently assigned to the Southeast Asian Elephant Pupinid snail genus Pollicaria Gould, 1856 is reassessed. Shell, radular and reproductive morphology are investigated and analysed with reference to karyotype patterns previously reported and to distribution patterns among the species. Six previously described species are recognised: Pollicaria gravida (Benson, 1856), Pollicaria myersii (Haines, 1855), Pollicaria mouhoti (Pfeiffer, 1862), Pollicaria elephas (Morgan, 1885), Pollicaria crossei (Dautzenberg & d'Hamonville, 1887) and Pollicaria rochebruni (Mabille, 1887). A new subspecies, Pollicaria mouhoti monochroma ssp. n.,is proposed and a dichotomous key to species is provided.
对目前归入东南亚象鼻螺属波利卡里亚·古尔德(Pollicaria Gould)的物种现状进行了重新评估。参照先前报道的核型模式以及各物种间的分布模式,对贝壳、齿舌和生殖形态进行了研究与分析。确认了六个先前描述的物种:波利卡里亚·格拉维达(Pollicaria gravida)(本森,1856年)、波利卡里亚·迈尔斯氏螺(Pollicaria myersii)(海恩斯,1855年)、波利卡里亚·穆霍蒂螺(Pollicaria mouhoti)( Pfeiffer,1862年)、波利卡里亚·象螺(Pollicaria elephas)(摩根,1885年)、波利卡里亚·克罗斯氏螺(Pollicaria crossei)(道岑贝格和达蒙维尔,1887年)以及波利卡里亚·罗切布鲁尼螺(Pollicaria rochebruni)(马比尔,1887年)。提出了一个新亚种,即单色波利卡里亚·穆霍蒂螺(Pollicaria mouhoti monochroma ssp. n.),并提供了物种检索表。
