Types. Holotype: male from Hacienda Hierba Buena, Sierra Nevada de Santa Marta, San Pedro de la Sierra, Ciénaga, Magdalena, Colombia, 2104 m, 10.895138°N, 73.999611°W, 6.V.2016, L. Martínez (ICN-Ar 8205). Paratypes: one male and one female with same data as holotype (ICN-Ar 8206–8207).

Etymology. The species epithet is a noun in apposition that honors the Chibcha-speaking indian tribe, the Arhuaco, who lives today in the area of the Sierra Nevada de Santa Marta, and is a direct descendant of the Tayrona indigenous people, together with the Kankuamo, Kogui and Wiwa.

Diagnosis. Males of H. arhuaco sp. nov. can be recognized from those of the remaining species of the genus by its semi-membranous quadrangular retroventral tibial apophysis (RvTA), the straight RTA, and a very long embolus (Figs 7–9). Females can be diagnosed by the epigyne with transverse posterior digitiform glands (dg), oval spermathecae and large atria containing the posteromedial copulatory openings (Figs 10–11).
