Six new species of the genus Eutichurus Simon, 1897 are described: E. murgai new species (based on male and female) and E. paredesi new species (male) from Peru; E. cumbia new species (female) and E. tequendama new species (male) from Colombia; E. yungas new species (male and female) from Bolivia, and E. nancyae new species (male and female) from Brazil. The males of E. marquesae Bonaldo, 1994, E. madre Bonaldo, 1994 and E. zarate Bonaldo, 1994 are described for the first time. Eutichurus brescoviti Bonaldo, 1994, described on males, is synonymized with E. tropicus (L. Koch, 1866), previously known only from females. New records for E. ibiuna Bonaldo, 1994, E. ravidus Simon, 1897, E. putus O. Pickard-Cambridge, 1898, E. silvae Bonaldo, 1994, E. lizeri Mello-Leitão, 1938, E. saylapampa Bonaldo, 1994, E. tropicus and E. manu Bonaldo, 1994 are presented. A key to all species of Eutichurus is provided, variation in the epigynal morphology of E. ibiuna is recorded and the fine morphology of E. marquesae is documented.
本文描述了1897年西蒙(Simon)所命名的优蒂蛛属(Eutichurus)的6个新物种:来自秘鲁的穆尔盖优蒂蛛新物种(E. murgai,基于雄性和雌性标本)和帕雷德斯优蒂蛛新物种(E. paredesi,雄性);来自哥伦比亚的昆比亚优蒂蛛新物种(E. cumbia,雌性)和特昆达马优蒂蛛新物种(E. tequendama,雄性);来自玻利维亚的永加斯优蒂蛛新物种(E. yungas,雄性和雌性),以及来自巴西的南希优蒂蛛新物种(E. nancyae,雄性和雌性)。首次描述了1994年博纳尔多(Bonaldo)所命名的马克塞优蒂蛛(E. marquesae)、马德雷优蒂蛛(E. madre)和萨拉特优蒂蛛(E. zarate)的雄性形态。1994年基于雄性标本描述的布雷斯科维蒂优蒂蛛(E. brescoviti)被认定为与热带优蒂蛛(E. tropicus,L. 科赫,1866年)同义,热带优蒂蛛此前仅知有雌性形态。文中还给出了1994年博纳尔多所命名的伊比乌纳优蒂蛛(E. ibiuna)、1897年西蒙所命名的拉维德优蒂蛛(E. ravidus)、1898年O. 皮卡德 - 剑桥所命名的普图斯优蒂蛛(E. putus)、1994年博纳尔多所命名的西尔瓦优蒂蛛(E. silvae)、1938年梅洛 - 莱特昂(Mello-Leitão)所命名的利泽里优蒂蛛(E. lizeri)、1994年博纳尔多所命名的萨伊拉潘帕优蒂蛛(E. saylapampa)、热带优蒂蛛以及1994年博纳尔多所命名的马努优蒂蛛(E. manu)的新记录。提供了一份优蒂蛛属所有物种的检索表,记录了伊比乌纳优蒂蛛外雌器形态的变异,并对马克塞优蒂蛛的精细形态进行了记录。
