Etymology. The name of the species comes from “Mamor,” a contraction of two words in Spanish, “mi amor,” meaning “my love.” Additionally, the name is latinized by appending the suffix -is, which corresponds to the singular genitive form in the third declension. This choice is given by the fact that “amor” traces its origins back to the Latin term “amor, amôris,” belonging to the third declension group. This appellation originates from the intimate address of Juan Manuel Rodríguez Sandoval, the collector of the type material, to María Alejandra Tapias González. Therefore, the species’ name serves as a dedication to her.

Distribution. This species is only recorded for the type locality in the locality of Pandi, of the department of Cundinamarca in Colombia. This species is probably endemic to this region, due to the isolation caused by the Andes mountain system ( Fig. 6 View FIGURE 6 ).

Diagnosis. Nops mamoris sp. nov. resembles similar congeners, with dorsal abdomen patterns and a long embolus, Nops guanabacoae MacLeay , Nops amazonas (Sánchez-Ruiz & Brescovit, 2018) , Nops itapetinga (Sánchez-Ruiz & Brescovit, 2018) , Nops maculatus Simon, 1893 , having a long and curved embolus; but can be distinguished by the proximal base of the embolus, which is more than a third of the bulb´s width, and its bulb is a similar width to the cymbium, the embolus length is a third longer than the cymbium ( Fig. 3 View FIGURE 3 ). The bulb is more elongated in N. guanabacoae and N. maculatus . The coloration of the opisthosoma in Nops mamoris sp. nov. is intense blue while alive, with no white or gray regions like the ones seen in the other mentioned species, and presents abdominal patterns of darker blue. These patterns of coloration could be similar to Nops quito Dupeìrreì, 2014 and Nops variabilis Keyserling, 1877 nevertheless, in both cases the pedipalp bulb is smaller and the embolus is shorter. In Nops mamoris sp. nov., the postero-medial and postero-lateral spinnerets are placed in the same line and have almost the same length, the posterior spinnerets are a third longer and also wider than the others. The bases of all spinnerets are placed at the same position or higher, over the opisthosoma ( Fig. 2 View FIGURE 2 A-B). The female presents a thin posterior plate (as wide as the lateral extensions), and posterior spiracles are a third length of the posterior plate. Internal genital with a narrow, almost rectangular ue, and thin re with two small lo in the medial region (Fig. 4,5).

Description. Male Holotype. Prosoma: Carapace: dark orange, chelicerae, legs, coxae, labium, endites, and sternum orange, however, the coxae are lighter. The carapace presents some patches of darker coloration. The eyes are separated by at least half of the width of the eye, a black patch surrounds the eyes, however, it does not protrude too much from the ocular area. The distance from the black ocular patch to the frontal margin is equal to the diameter of the patch ( Fig. 1A View FIGURE 1 ). Chelicerae: are inserted at eye height, the distal margin of the bases of the chelicerae equals the frontal margin of the carapace, and fangs are orange and thin at the distal region, curved inwardly. The endites are tubular and curved with a yellow apex. Sternum: dark-orange coloration, dotted surface, and covered by a spaced hairiness. The labium and sternum are fused ( Fig. 1B View FIGURE 1 ).

Opisthosoma: Oval shape, a third longer than the prosoma. Coloration intensely blue (pre-and postmortem), dorsally with patches of darker coloration, two patches at the anterior region followed by three transversal bands, bands two and three are joined by the central diamond-shape patches ( Fig. 1C View FIGURE 1 ). Ventrally, the blue coloration presents patches with dots of darker coloration, two patches at the medial portion, and a triangle-shaped patch at the posterior region ( Fig. 1D View FIGURE 1 ). Coloration remains equal nine months after it was collected but it could change in the future. Spinnerets: PLS form a line with the PMS, both are shorter than the ALS ( Fig. 2 View FIGURE 2 A-B).

Legs: lengths configuration: IV<I<II<III. All legs with three claws, and pretarsal paired claws with a single line of teeth. Adesmatic joint present ( Fig. 2 View FIGURE 2 C-D). Posterior unpaired claws elongated and dorsally reflexed.

Male genital: The pedipalp bulb is as wide as the cymbium, the cymbium is a third longer than the bulb. Embolus twice as long as the tibia, spiral-curved, and thinner and less sclerotized at the distal half. The base of the embolus is conical and thick ( Fig. 3 View FIGURE 3 ).

Female Paratype. Most characters, as in the male, body lengths are provided in Table 1 View TABLE 1 . The coloration patterns of the Opisthosoma are equal to the male, but less bright, with a gray-blue tone. The femorae present a longitudinal stain of lighter coloration which is not present in the male ( Fig 4A View FIGURE 4 ).

Female genital: The posterior plate (pp) is thin, with small and rounded lateral extensions (lep), and the anterior margin of the receptaculum (amr) is externally small, with non-pronounced lobes (lo) ( Fig. 4 View FIGURE 4 B-C). Internal genital with a thin posterior receptaculum (re) which presents to small lo in the medial region, the lo are half of high of the re and encompass a third of the width of the re. The respiratory system presents two pairs of thick posterior tracheae ( Fig. 5 View FIGURE 5 ).

Ecological information: The specimens were collected in an anthropized environment, the holotype male was found in a rift over a wall. Other specimens were found in a partially dried water ravine, in the leaf litter, and over trees. All specimens were found at the same place, with a distance of about 10m between them. No other specimens were observed, however, other spiders of the families Araneidae , Clubionidae , Corinnidae , Salticidae , Scytodidae , and Theridiidae were observed at the collected points.
