On the genus Diphya: notes on the Brazilian D. bicolor and a new species from Ecuador (Araneae: Tetragnathidae)

ABSTRACT In this paper a new species of Diphya Nicolet, 1849, D. napo sp. nov. is described based on males and females from Ecuador. The female of Diphya bicolor Vellard, 1926 is described and illustrated for the first time and new records are presented. Oarces ornatus Mello-Leitão, 1935 and Azilia eximia (Mello-Leitão, 1940) are synonymized with D. bicolor, being A. eximia removed from the synonym of Azilia Keyserling, 1881 and being Cardimia Mello-Leitão, 1940 considered synonym of Diphya.

摘要 本文基于采自厄瓜多尔的雌雄标本，记述了妩蛛属（Diphya Nicolet, 1849）1新种——纳波妩蛛（D. napo sp. nov.）。首次对双色妩蛛（Diphya bicolor Vellard, 1926）的雌蛛进行形态记述与图解，并提供该种的新分布记录。将饰纹奥蛛（Oarces ornatus Mello-Leitão, 1935）与奇异阿蛛（Azilia eximia (Mello-Leitão, 1940)）归为双色妩蛛的同物异名；其中将奇异阿蛛从阿蛛属（Azilia Keyserling, 1881）的同物异名组合中移出，并将卡迪蛛属（Cardimia Mello-Leitão, 1940）视为妩蛛属的同物异名。
