Abstract

In this study, seven new species of the genus Synprosphyma are described from Southwest China, namely S. abiens sp. nov., S. jinhuo sp. nov., S. muzzybbep sp. nov., S. subserrata sp. nov., S. wumeng sp. nov. from Yunnan, S. longmen sp. nov., from Sichuan and S. yuanqini sp. nov. from Guizhou. All species have significant morphological differences that clearly distinguish them from congeners. Additionally, S. imperatrix (Boettger & Schmacker, 1894) and S. suilla (Bavay & Dautzenberg, 1909) are redescribed based on newly collected materials.

摘 要

本文报道了产自中国西南地区的瘤管螺属 Synprosphyma Wagner, 1920 七个新种：裂褶瘤管螺 Synprosphyma abiens sp. nov.、金火瘤管螺 Synprosphyma jinhuo sp. nov.、目则山瘤管螺 Synprosphyma muzzybbep sp. nov.、锯齿瘤管螺 Synprosphyma subserrata sp. nov. 和乌蒙瘤管螺 Synprosphyma wumeng sp. nov. 均产自云南省；龙门瘤管螺 Synprosphyma longmen sp. nov. 产自四川省；愿琴瘤管螺 Synprosphyma yuanqini sp. nov. 产自贵州省。上述新种在贝壳形态上与已知瘤管螺属物种存在显著差异，可与同属其他种类明确区分。此外，本文基于新采集材料对首要瘤管螺 Synprosphyma imperatrix (Boettger & Schmacker, 1894) 和壮硕瘤管螺 Synprosphyma suilla (Bavay & Dautzenberg, 1909) 进行了重新描述。
