摘要

阿根廷放线虫属(Actinopus Perty)， 1833年修订，共包括23种。首次描述了A. insignis (Holmberg, 1881)的雌性;该物种分布在布宜诺斯艾利斯北部、圣达菲南部和乌拉圭。本文首次描述了以前只从乌拉圭的雄性类型中发现的A. longipalpis (Koch, 1842)的雌性，并在阿根廷引用了该物种(Entre Ríos)。20个新物种被发现、描述和图解。13个新种是基于雄性和雌性(A. reycali, sp. nov.，来自Jujuy和Salta;A. clavero, sp. nov，来自Córdoba;A. szumikae, 11月，来自Córdoba，布宜诺斯艾利斯南部，圣达菲和科伦特斯;a . coylei sp. 11月,萨尔塔和圣地亚哥德尔三角湾,a . argenteus sp. 11月,从圣地亚哥德尔三角湾,科尔多瓦和的卡塔马卡,a . ramirezi sp. 11月,从计划,a·巴塔哥尼亚sp. 11月,从丘布特拉潘帕,里约热内卢黑人和布宜诺斯艾利斯南部,a . gerschiapelliarum sp. 11月,科尔多瓦,布宜诺斯艾利斯北部,南部圣达菲北部拉潘帕Canelones乌拉圭,a .南美大草原sp. 11月,从拉潘帕,a . septemtrionalis sp. 11月,从萨尔塔,图库曼省,的卡塔马卡,福尔摩沙,A. taragui, sp. 11月，来自Corrientes, Chaco，和Misiones, A. excavatus, sp. 11月，来自Córdoba, A. casuhati, sp. 11月，来自布宜诺斯艾利斯南部)。只有一种新种仅以雌性为基础(A. indiamuerta, sp. nov.，来自Tucumán);其余6只为雄性(11月A. puelche, sp.，来自布宜诺斯艾利斯南部和乌拉圭;11月A. cordobensis, sp.，来自圣路易斯和Córdoba; 11月A. magnus, sp.，来自Córdoba; 11月A. ariasi, sp.，来自福尔摩沙;11月A. palmar, sp.，来自恩特雷Ríos; 11月A. balcarce, sp.，来自布宜诺斯艾利斯南部)。新的形态特征，可以帮助解决系统发育关系在属描述。提供了来自阿根廷的所有物种的二分类键，以及所有物种的已知地理分布地图。这里处理的三种(A. gerschiapelliarum, A. puelche和A. insignis)在乌拉圭也有记录。

Taxonomic Revision and Morphology of the Trapdoor Spider Genus Actinopus (Mygalomorphae: Actinopodidae) in Argentina

ABSTRACT The genus Actinopus Perty, 1833, is revised for Argentina, comprising a total of 23 species. The female of A. insignis (Holmberg, 1881) is described for the first time; the species is found in northern Buenos Aires, southern Santa Fe, and Uruguay. The female of A. longipalpis (Koch, 1842), previously known only from the male type from Uruguay, is described for the first time, and the species is newly cited for Argentina (Entre Ríos). Twenty new species are recognized, described and illustrated. Thirteen of the new species are based on males and females (A. reycali, sp. nov., from Jujuy and Salta; A. clavero, sp. nov., from Córdoba; A. szumikae, sp. nov., from Córdoba, southern Buenos Aires, Santa Fe and Corrientes; A. coylei, sp. nov., from Salta and Santiago del Estero, A. argenteus, sp. nov., from Santiago del Estero, Córdoba and Catamarca, A. ramirezi, sp. nov., from Misiones, A. patagonia, sp. nov., from Chubut, La Pampa, Río Negro and southern Buenos Aires, A. gerschiapelliarum, sp. nov., from Córdoba, northern Buenos Aires, southern Santa Fe, northern La Pampa and Canelones in Uruguay, A. pampa, sp. nov., from La Pampa, A. septemtrionalis, sp. nov., from Salta, Tucumán, Catamarca, and Formosa, A. taragui, sp. nov., from Corrientes, Chaco, and Misiones, A. excavatus, sp. nov., from Córdoba, A. casuhati, sp. nov., from southern Buenos Aires). Only one of the new species described is based on females only (A. indiamuerta, sp. nov., from Tucumán); and the remaining six on males (A. puelche, sp. nov., from southern Buenos Aires and Uruguay, A. cordobensis, sp. nov., from San Luis and Córdoba, A. magnus, sp. nov., from Córdoba, A. ariasi, sp. nov., from Formosa, A. palmar, sp. nov., from Entre Ríos, and A. balcarce, sp. nov., from southern Buenos Aires). New morphological characters that can help solve phylogenetic relationships within the genus are described. A dichotomous key for all the species from Argentina is provided, as well as maps of the known geographic distribution for all the species. Three of the species treated here (A. gerschiapelliarum, A. puelche, and A. insignis) are recorded also for Uruguay.

期刊介绍： The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates, published short papers describing new forms.
