Type material. HOLOTYPE. Male: COLOMBIA, Antioquia, Bello, Páramo Baldías, Jama, 6.3422222ºN, 74,64777778ºW, 2900–3000 m [eters], 10.jul[VII].2013, J. [A.] Rafael, J.T. Câmara & [F.F.] Xavier leg (1 ♂, CEUA-101626) (photographed) . Holotype with right wing mounted on microslide in Canada balsam, left antenna and terminalia placed in a microvial with glycerin.

Etymology. The specific epithet refers to the type locality, Páramo Baldías, Private Reserve Protection, Colombia.

Geographical distribution. Colombia (Antioquia, Bello) (Fig. 4).

Habitat. The specimen was collected in the Páramo Baldías, with areas of very humid premontane forest of the Central cordillera of the Northwest region of Colombia, where the vegetation is composed of Andean clouded forests (Andean Forests 2024).

Taxonomic notes. Cephalops baldiensis sp. nov. runs to C. klinsmanni Ramos-Pastrana, Marques & Rafael, 2022 in the couplet 17 of the key presented by Ramos-Pastrana et al. (2022). It differs from C. klinsmanni by having postpedicel brown, with rounded apex (Fig. 1C) [versus postpedicel dark brown, with acuminate apex, figure 51 in Ramos-Pastrana et al. (2022)]; legs mainly yellow (Fig. 1C) [versus legs mainly brown to dark brown, figure 49, 50 in Ramos-Pastrana et al. (2022)]; abdomen shiny (Figs 1A–B, F) [versus abdomen velvety, figures 49–50, 54 in Ramos-Pastrana et al. (2022)]; other differential characters of the male genitalia are well specified in the key below. Based on males and due to the shape bifid of phallus, C. baldiensis sp. nov. is also related to C. brasiliensis Hardy, 1950 [figure 11 in Rafael (1990)]; C. farallonensis sp. nov. (Fig. 2K) and C. nitidus Hardy, 1950a [figure 37 in Rafael (1990)]. It differs from C. brasiliensis by having postpedicel with rounded apex (Fig. 1C) [versus postpedicel with acute apex in C. brasiliensis, figure 8A in Hardy (1950)]; both surstyli only slightly thinning at base and apex (Fig. 1H) [versus both surstyli thickened at base, only slightly thinning at apex, figure 9 in Rafael (1990)]; both surstyli with inner margin straight (Fig. 1H) [versus right surstylus with inner margin sinuous, figure 9 in Rafael (1990)]; apex of phallic without lobes at apex (Fig. 1L) [versus apex of phallic with three lobes thin and acute apex dorsally, figure 11 in Rafael (1990)]; ejaculatory ducts of phallus with truncated apex (Fig. 1L) [versus ejaculatory ducts of phallus with acute apex, figure 11 in Rafael (1990)]. It differs from C. farallonensis sp. nov. by having trochanters light brown; fore and mid femora proximal half brown and distal half yellow, fore femur with proximal two thirds brown and distal third yellow (Fig. 1A) [versus trochanters and femora entirely yellow in C. farallonensis sp. nov. (Fig. 2A)]; left surstylus with rounded apex (Fig. 1A) [versus left surstylus with acute apex (Fig. 2A)]; gonopods with acute apex (Fig. 1K) [versus gonopods with rounded apex (Fig. 2J)]; ejaculatory ducts of phallus with truncated and membranous apex (Fig. 1L) [versus ejaculatory ducts of phallus with rounded and sclerosed apex (Fig. 2K)]. It differs from C. nitidus by having both surstyli only slightly thinning at base and apex (Fig. 1H) [versus both surstyli thickened at base, only slightly thinning at apex in C. nitidus, figure 36 in Rafael (1990)]; apex of phallic guide without lateral setae on apex (Fig. 1L); [versus apex of phallic guide with lateral setae and two lobes laterally on apex, figure 37 in Rafael (1990)]; ejaculatory ducts of phallus with truncated apex (Fig. 1L); [versus ejaculatory ducts of phallus with acute apex, figure 37 in Rafael (1990)].
