Abstract

Two new species of Milnesium are described, Milnesium minutum sp. n. from Sicily and Milnesium sandrae sp. n. from the Hawaiian Archipelago. The body size of Milnesium minutum is the smallest of the known species of the genus. The stylet supports are inserted on the buccal tube at 63-66% of its length and the claws have a [3-3]-[3-3] configuration. Milnesium sandrae has stylet supports inserted on the buccal tube at 58-60.5% of its length, a [3-3]-[3-3] claw configuration, and the percent ratio between the secondary claw and primary claw length on legs I-III (78.6%-85.5%) clearly higher than on legs IV (70.5%-71.4%). With the description of these two new species, the number of species in the genus is increased to 31.

摘要

描述了米尔恩斯缓步动物属的两个新物种，即来自西西里岛的微小米尔恩斯缓步虫（Milnesium minutum sp. n.）和来自夏威夷群岛的桑德拉米尔恩斯缓步虫（Milnesium sandrae sp. n.）。微小米尔恩斯缓步虫的体型是该属已知物种中最小的。口针支撑位于口管长度的63%-66%处，爪的构型为[3-3]-[3-3]。桑德拉米尔恩斯缓步虫的口针支撑位于口管长度的58%-60.5%处，爪的构型为[3-3]-[3-3]，并且第一至三对足上的次生爪与原生爪长度的百分比比值（78.6%-85.5%）明显高于第四对足（70.5%-71.4%）。随着这两个新物种的描述，该属的物种数量增加到了31种。
