中文摘要 | 臺灣招潮是臺灣之特有種招潮蟹,過去由於保存於國外博物館的標本很少,造成許多分類上的錯誤,因此有必要針對歷來文獻中的誤解之處加以訂正。Crane在1975年把臺灣招潮歸類於海招潮亞屬(subgenus Thalassuca)之中,然而,許多臺灣招潮的重要特徵-雄蟹螫足左右性的比例、雌蟹小螫兩指間的大齒、前側緣、眼下緣、眼窩底部、背甲的隆起程度、棲所位置、基質成份-均與海招潮亞屬的另兩個成員(四角招潮U.tetragonon和呼喚招潮U.vocans)很大的差異,因此提議臺灣招潮應該排除在海招潮亞屬之外。本報告除針對臺灣招潮的分類地位做修訂之外,並整理歷年來對臺灣招潮的研究情形、在臺灣本島和澎湖地區的分布狀況、種內形態的變異(短細螯的比例)、活體的顏色、以及其他對臺灣招潮誤解之處的訂正。 |
英文摘要 | Uca formosensis Rathbun, 1921, is an endemic fiddler crab species from Taiwan. The taxonomy of this species has long been constrained by the paucity of study material. Crane (1975) placed U. formosensis as a member of the subgenus Thalassuca, but important characters, like its handedness, presence of enlarged teeth on the fingers of the female's minor chela, structures of the anterolateral margin, suborbital margin, orbital floor, degree of arching of the carapace, and habitat preference, suggest that this classification is incorrect. It is suggested that U. formosensis should be excluded from the subgenus Thalassuca. In this study, a historic review is provided of the species and notes on its distribution, variation of morphology (chela types), live coloration, and taxonomy are included. |
