臺灣產蟹蛛亞科（蜘蛛目：蟹蛛科）之分類研究

Abstract

蟹蛛亞科(Thomisinae)是蜘蛛目世界第六大科蟹蛛科裡的最大亞科，也臺灣常見的蜘蛛之一，常見於灌叢、林地及田間。蟹蛛亞科的成員，身上花色多變，從灰白、黃綠到深棕皆有，前兩對步足向兩側展開如螃蟹一般長而粗，可幫助其有效的捕食。蟹蛛亞科也廣泛分佈於世界各地，目前全世界共有超過1500種。本論文共報告臺灣產蟹蛛亞科共12屬26種。新紀錄屬為羽蛛屬（Ozyptila）共一屬; 新紀錄種有七種，分別為龍岐虎斑蟹蛛（Tmarus longqicus）、松本羽蛛（Ozyptila matsumotoi）、農甲羽蛛（Ozyptila nongae）、鞍形花蟹蛛（Xysticus ephippiatus）、千島花蟹蛛（Xysticus kurilensis）、廣西三角蟹蛛（Thomisus guangxicus）、帶花葉蛛（Synaema zonaton）; 新種兩種，分別為海端虎斑蟹蛛（Tmarus haituanus sp. nov.）、霧台三角蟹蛛（Thomisus wutaiensis sp. nov.）。另外將Misumenoides formosipes 列為疑問種。本研究結果，增加對臺灣產蟹蛛亞科蜘蛛的物種與資源多樣性的了解，並可作為未來系統演化與行為研究之基礎。

Being the largest subfamily of the top sixth spider family in the world, Thomisinae (Araneae: Thomisidae), over 1500 species, is one of the common arachnid groups in Taiwan. The Thomisinae is usually called crab spider because of the first two legs are strong, long and laterigrade. The thomisids distribute among the shrubs, the fields and the frosts. They don’t build webs but sit-and wait to capture prey. And the varied coloration of body which are gray-white, yellow-green or evan brownish spot pattern reflects the varied habitat they live. Totally twelve genera, and twenty-eight species are reported from Taiwan, including one newly record genus: Ozyptila. The two new species are: Tmarus haituanus sp. nov., Thomisus wutaiensis sp. nov. The seven new record species are: Tmarus longqicus, Ozyptila matsumotoi, Ozyptila nongae, Xysticus ephippiatus, Xysticus kurilensis, Thomisus guangxicus, Synema zonaton. One species, Misumenoides formosipes remained doubtful. This taxonomy study reveals the intact species record and geographical distribution from Taiwan.
