Etymology. The specific epithet comes from “bullerengue”, a type of cumbia music and dance traditionally performed by women from Afro-descendant/Maroon communities of the Colombian Caribbean where the new species has been found; noun in apposition.
Diagnosis. Females of S. bullerengue sp. nov. can be differentiated by the copulatory ducts, which form an oval and do not extend to the edges of the epigynal plate posteriorly (Figs 26, 29, 55). When the genitalia is viewed caudally, the spermathecae and ducts visible through the integument resemble commas (Fig. 55). Males of the new species can be distinguished by the wide base of the dRTA (Fig. 37). Also, the tegulum abruptly protrudes basally, and the tip of the conductor is a large, unsclerotized rectangle with sclerotized bifurcate branches—one pointed and one hook shaped (Figs 36, 43, 46, 49, 51).
Description. Female (holotype):

Carapace brownish yellow with dark markings; sternum yellowish, dark around border; chelicerae brownish yellow with dark markings anteriorly and anteromedially, extending the length of the chelicerae; maxillae yellowish brown, lightening distally; labium brown, lightening distally; abdomen yellowish gray with some white flecks, with dark markings medially that widen and contract in the upper and lower third, dark flecks extend laterally from the central area, dark festoon on abdomen posteriorly, ALS and PLS darkened dorsolaterally; abdomen ventrally grayish yellow, dark laterally; legs yellowish tan with dark annulations on all leg segments; speckles on effectively ventral surface (prolateral) of pt and ti I and II.
