  The pholcid spiders of Tunisia (Araneae: Pholcidae): new species, new records, and deep COI divergence in Holocnemus reini Abstract Tunisia features a rapid transition between Mediterranean and Saharan biogeographical zones, resulting in a high degree of environmental heterogeneity. Despite this ecological diversity, Tunisian spiders have received limited attention compared to those of neighboring Maghreb countries. Here we combine the results of recent collections in Tunisia focusing on Pholcidae with a comprehensive review of previously published information, resulting in a total of six genera and eleven species. We present first records of the genera Micropholcus Deeleman-Reinhold & Prinsen, 1987 and Spermophorides Wunderlich, 1992 for Tunisia, represented by four new species: M. kahinae Huber sp. nov., M. echebbii Huber sp. nov., S. nabilae Huber & Kmira sp. nov., S. bchirae Huber sp. nov.; in addition, we redescribe S. huberti (Senglet, 1973) from Tunisian specimens,...

Abstract
A new species of the genus Actinopus Perty, 1833, belonging to the cucutaensis group, is described from Colombia. The new species, Actinopus embera sp. nov., was discovered in the departments of Córdoba, Bolivar, Sucre, and Atlántico, located along Colombia’s Caribbean coast, and is readily distinguished by genital organ morphology. Additionally, we report a possible case of phoresis between a mite of the family Acaridae Latreille, 1802 and a female and three immature specimens of Actinopus embera sp. nov. from one of the type localities (Tiquisio, Bolí var). Finally, based on prior evidence and the events leading to the destruction of the type material, we propose Actinopus cucu taensis Mello-Leitão, 1941 as a species inquirenda.
