They raise to 33 the number of species described in the genus. An identification key to the males in the species group is included. Key words: Barklouse, Epipsocetae, Psocoptera, South America, taxonomy Introduction Euplocania Enderlein 1910 is one of 11 genera in the psocopteran family Ptiloneuridae (Silva Neto et al., 2018). It is the second richest genus in the family, with 22 described species and about 38 undescribed ones (González-Obando et al. 2017). García Aldrete et al. (2013) recognized eight species groups in Euplocania, based on wing pigmentation, number of forewing M veins, shape of pterostigma and hypandrium structure. The genus shows a wide spectrum of morphological variability and the number of species groups was recently increased to 12: Amabilis, Cerata, Guentherbuchi, Laelsa¸ Marginata, Yalcona, Zelayensis, “A”, “B”, “C”, “D” and “E” (González Obando et al. 2015; 2017). Species group Amabilis is diagnosed by having the forewing with a broad, pigmented marginal band from R 4+5 to cells ‘a’ and cu 2 ; pterostigma angulate, extended towards Rs; hypandrium of three sclerites, a large central one, flanked by two small ones and by having the central sclerite with two lateral posterior projections (García-Aldrete et al. 2013). This group included five described species: E. amabilis Enderlein, 1910 (Paraguay), E. badonneli New & Thornton, 1988 (Peru, Brazil, Colombia), E. macarenaensis González, García Aldrete & Carrejo, 2015 (Colombia), E. picta New, 1980 (Brazil) and E. pictaoides García Aldrete, 1998 (Peru) and six undescribed species previously reported by García Aldrete et al. (2013): Euplocania V, Euplocania VI, Euplocania IX, Euplocania X, Euplocania XI from Brazil, and Euplocania XVI, from Ecuador. In addition, five undescribed Colombian species were found, upon examination of specimens collected in the framework of the project “Revisión Taxonómica y Endemismo de los Psócidos (Insecta: Psocodea: ‘Psocoptera’) de Areas Protegidas De Colombia”, in the Departments of Chocó, Meta, Putumayo, Valle del Cauca and Vaupés. The purpose of this work is to describe and illustrate these 11 species. Materials and methods 20 males were available for study, ten of which belong to the Grupo de Investigaciones Entomológicas (Departamento de Biología, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Santiago de Cali, Colombia) collection and are deposited in the Museo de Entomología de la Universidad del Valle (MUSENUV)
