Figure 2 A−C, 4.

Type material. Holotype: female from Finca El Llanito (6°50′29.69″N; 73°23′13.49″W), 1313m, Parque Nacional Natural Serranía de los Yariguies San Vicente de Chucurí Vereda Centro, Santander, Colombia, 13–15.X.2015, J. A. Moreno-González leg. (ICN-Ar 10644).

Etymology. The specific epithet is a patronymic given in honor of the deceased Argentine singer Gustavo Cerati, who has greatly contributed to Spanish Rock music.

Diagnosis. Females of Macrophyes ceratii n. sp., can be distinguished of the remain species of the genus by their long copulatory ducts, curved toward the medial region of the epigynum; long atrium, widening posteriorly to a circular shape and small, oval-shaped spermathecae ( Figs 2B, C ).

Description. Female (Holotype, ICN–Ar 10644). Coloration uniformly pale yellow ( Fig. 2A ). Total length 6.32, carapace length 1.81, width 1.28, high 0.77. Clypeus height 0.04. Eye diameters and interdistances:AME 0.06, ALE 0.11, PME 0.10, PLE 0.09; AME–AME 0.14, AME–ALE 0.23, PME–PME 0.29, PME–PLE 0.27, ALE–PLE 0.21. Chelicerae 0.74 long, eight promarginal teeth, nine retromarginal teeth, being the distal longer than other. Leg measurements: leg I—femur 5.93/ patella 0.81/ tibia 6.71/ metatarsus 6.41/ tarsus 2.01/ total 24.87; II—4.89/ 0.81 / 5.07/ 4.91/ 1.47/ 17.15; III—3.27/ 0.63/ 2.78/ 3.39/ 0.99/ 11.06; IV—5.44/ 0.79/ 4.61/ 5.94/ 1.49/ 18.27. Leg spination: I—metatarsus p1-0-0-0-0; II—tibia d0-0-0-0-1, p0; II=I; III—tibia d0-0-0-0-1, v0-2-0-2-0, p0-0-1-0-1, r0- 0-1-0-1, metatarsus v2-0-0-2-0, r1-0-1-0-0, p1-0-1-0-0; IV—tibia d1-0-0-0-0, v0-1-0-0-1, p0-0-1-1-1, r0-0-1-1-1, metatarsus v0-2-0-1-0, p1-0-0-1-1, r1-0-1-1-1. Abdomen: length 4.52, epigastric furrow 0.83 from tracheal spiracle, spiracle 3.07 from base of spinnerets. Epigynum: atrium longer than wide, cylindric-shaped, rounded posteriorly; lateral borders thin, sclerotized, laminar; internally with very long, thin copulatory ducts, curved at medial region; seminal receptacles small and rounded, sub-medially situated on the copulatory ducts; spermathecae large, ovalshaped, posteriorly positioned; fertilization ducts almost as long as the spermathecae ( Figs 2B, C ).

Male. Unknown.

Distribution. Only known from the type locality ( Fig. 4 ).

Habitat. The specimens were collected beating low shrubs, on foliage, in a conserved high mountain wet forest ecosystem, at 1313–1702 meters high.
