Reproductive System of Land Snail Satsuma contraria (Stylommatophora: Camaenidae)

左旋蝸牛(柄眼目:南亞蝸牛科)的生殖系統

摘要


Satsuma contraria is narrowly distributed in southern Taiwan. Newly collected materials of the species from Kenting Forest Recreation Area were dissected and compared in the present study. The genitalia of the species is characterized by having a vermiform flagellum, a short penial caecum, a degenerated verge and a swollen pedunculus of the bursa copulatrix at middle part. The type specimens deposited in the Academy of Natural Sciences of Philadelphia of this species were also examined for correct identification.

左旋蝸牛只侷限分佈在南台灣,過去本種的生殖系統並未有解剖報告,本文解剖並比較採集自屏東恆春墾丁森林遊樂區的新採集標本,本種的生殖系統具有蠕蟲狀的鞭狀器、短的陰莖盲囊、不顯著的陰莖緣與中段膨大的交配囊柄,這些特徵與本屬其他種有所不同,可以做為分類與生物系統學的特徵。我們也檢視存放在費城自然科學院的模式標本,作為正確鑑定的依據。
