Etymology:
The specific name is a noun in apposition taken from the Kichwa language meaning “spiral”.
Diagnosis.
Males and females are distinguished from all species, by the ALE separated by three time their diameter and absence of metatarsal and tarsal cusps (
Figs 16, 17
). Furthermore, males are diagnosed by large anvil–shaped retrolateral patellar apophysis (
Fig. 15
) and female by their copulatory ducts making one loop (
Fig. 19
).

Description.
Male (
paratype
)
: Total length: 0.93; carapace length: 0.38; carapace width: 0.36; abdomen length: 0.55; abdomen width: 0.47; clypeus height: 0.13. Cephalothorax: Carapace reddish-orange; pars cephalica puntated; cephalic groove deep, strongly punctated; pars thoracica dorsally and laterally punctated (
Fig. 50
). Sternum orange, suffused with dark gray, punctated, longer than wide, covered with setae. Clypeus orange, punctated. Labral spur present. Chelicerae orange, excavated medially; with one basal tooth and denticulate plate apically. Eyes: 6 eyes, rounded; AME absent, ALE separated by
3x
their diameter, ALE-PLE contiguous, LE-PME separated by
1x
their diameter, PME contiguous. Abdomen: rounded, with dorsal orange scutum; soft portion whitish with a few setose sclerites (
Fig. 50
); complete spinneret scutum. Legs: Reddish-orange, metatarsus I–II not swollen without cusps, tarsus I–II without cusps (
Figs 16, 17
). Genitalia: Palpal patella with large anvil-shaped, ventrally curved retrolateral apophysis; palpal tibial trichobothrium not observed; strongly recurved tibial apophysis (
Fig. 15
). Cymbium cup-shaped without extension (
Figs 14, 15
). Embolus long exiting the conductor; conductor semi-transparent, stongly ridged (
Figs 15, 15a
).
Female
(
paratype
, abdomen damaged): Carapace length: 0.44; carapace width: 0.36; clypeus height: 0.08. Same coloration and pattern of punctation as male. Chelicerae and sternum as male. Labral spur present. Eyes: 6 eyes, rounded; AME absent, ALE separated by
3x
their diameter, ALE-PLE contiguous, LE-PME separated by their diameter, PME contiguous. Abdomen: Whitish, rounded without dorsal scutum (damaged). Genitalia: Ventral scutum orange, visible through the scutum: a pair of large rounded spermathecae, large copulatory ducts (
Fig. 18
). Internal genitalia with large rounded spermathecae; copulatory ducts wide narrowing, making one loop; fertilization ducts recurved, directed basally (
Fig. 19
).
Distribution.
Ecuador
: Known only from the
type
locality.
Natural History.
All specimens were found in the cloud forest sifting litter or by pitfall trap between 1,997– 2,225m.
