摘　　要：描述了栖息于甘肃南部的陆生贝类艾纳螺科1新种,希氏金丝雀螺Serina schileykoi sp.nov.。与各已知种相比,新种的的次体螺层最膨大;毗邻缝合线处不具窄带区;轴唇具1向内延伸的钝齿。在生殖系统中,生殖开口牵引肌阙如;交接器细长,内具1个V-形壁柱。本种在形态上与戒金丝雀螺Serina egressa(Sturany,1900)最为接近。A new enid species Serina schilekyoi sp. nov. is described from South Gansu. The new spedes, closely related to Serina egressa （Sturany, 1900）, is characterized by the markedly swollen penultimate whorl, the absence of narrow defined zone on every beneath whorl, longer and more slender penis in which 1 V-shaped plasters is present, and the absence of atrial retractor muscle.
