台灣大臍蝸牛與台灣盾蝸牛(腹足綱:扁蝸牛)的生殖系統比較解剖

Comparative Anatomy of Aegista (Aegista) subchinensis and Aegista (Plectotropis) mackensii (Gastropoda: Bradybaenidae)

摘要


盾蝸牛屬分為兩亞屬,Aegista亞屬與Plectotropis亞屬,兩者從外觀上來看,Plectotropis有殼毛且周緣有龍骨突起,但Aegista沒有,兩者有很明顯的形態差異。本文中解剖台灣大臍蝸牛Aegista(Aegista)subchinensis與台灣盾蝸牛Aegista(Plectotropis)mackensii比較兩亞屬間生殖系統形態的差異。解剖後發現主要差異是1.台灣大臍蝸牛陰莖鞘占陰莖的比例較台灣盾蝸牛少;2.台灣大臍蝸牛的鞭狀器呈現不同形態;3.台灣大臍蝸牛有包覆陰莖本體與輸精管的膜狀結構;4.台灣盾蝸牛的輸卵管前段有明顯膨大處;5.兩者副矢囊的形態以及數量不相同,且連接的黏液腺數量也不同。

並列摘要


The genus Aegista is subdivided into two subgenus Aegista and Plectotropis. The latter has hair-like ornamentation and a keeled periphery, hence, they are easy to distinguish from each other. In this article, we dissected two Aegista species, Aegista (Aegista) subchinensis and Aegista (Plectotropis) mackensii, and compared their reproductive systems. They are different in the morphology of the penial sheath, the falgellum, the oviduct, the accessory-sac of auxiliary copulatory and number of mucus gland.
