臺灣產紅螯蛛屬蜘蛛之新紀錄種

A newly recorded species of Cheiracanthium C. L. Koch, 1839 (Araneae, Cheiracanthiidae) from Taiwan

"本報告依新採集標本及形態檢視，報告台灣產紅螯蛛屬蜘蛛之新紀錄種──短突紅螯蛛（Cheiracanthium insigne O. Pickard-Cambridge, 1874）。雌、雄性皆重新描述及拍攝，同時運用基因條碼驗證本種正確之性別配對，並回顧與近緣種的分類問題。由maximum likelihood親緣關係樹及以K2Pmodel計算之遺傳距離結果（平均種內遺傳距離為1.15％）皆驗證台灣產短突紅螯蛛的雌雄配對之正確性，並支持在過去研究中採集於印度阿薩姆的平庸紅螯蛛（C. triviale）雌蛛樣本應屬於本種。"

This paper provides a morphological description of a newly recorded species from Taiwan, Cheiracanthium insigne O. Pickard-Cambridge, 1874, based on newly collected materials. Both male and female C. insigne specimens are analysed, redescribed, and photographed. We applied DNA barcoding validation for matching sexes and reviewed taxonomic issues of C. insigne with other related species. The results of maximum likelihood tree and Kimura two-parameter genetic distance confirm the correct matching of male and female C. insigne specimens from Taiwan (mean intraspesific distance as 1.15%). In addition, the phylogenetic analysis suggests that previous female specimens of Cheiracanthium triviale from Assam, India, could potentially be conspecific to C. insigne from Taiwan.
