Diagnosis
Paramedian rounded tubercles widely separated in areas I, III and IV ( Figs 15 View Fig , 16A View Fig ). Ectal borders of protoglyphs conspicuous, triangular and sharp ( Figs 15A View Fig , 16A View Fig ). Coda short and wide ( Fig. 15A View Fig ). Clavi inguines large ( Fig. 15A View Fig ), basichelicerite with large tubercles in the basal part ( Fig. 17B View Fig ). Pedipalpal femur wider at half length ( Fig 17E View Fig ).
This species is very similar to E. scalaris in the shape of the ladder mask, but differs by having a short coda with the constriction poorly marked ( Fig. 15A View Fig ), the basichelicerite bears larger tubercles ( Figs 15A View Fig , 17B View Fig ) and the femur of leg IV is more tuberculated in the ventro-distal region ( Fig. 17 View Fig G–H, J). Apophyses of coxa IV acuminate and poorly tuberculated ( Figs 15 View Fig , 16A View Fig ).
Etymology
Noun in apposition of Leda, mother of Clytemnestra, Castor, Pollux and Helen of Troy, from Greek mythology. This species has been named Leda to round up the family formed from the union of Zeus and Leda.

Description
Male (based on holotype)
MEASUREMENTS. CL = 2.11, AL = 3.29, CW = 3.11, AW = 5.08, Fe IV = 5.19, Ti IV = 3.41.
DORSUM ( Figs 15 View Fig , 16A View Fig ). Dorsal scutum beta-shaped, with asymmetrical mid-bulge. Areas I, III and posterior margin with two paramedian tubercles, tubercles of posterior margin bifid. Lateral margins with irregular row of minute granules at mid-bulge. Posterior margin of scutum with row of small tubercles. Tergites with row of small tubercles and anal operculum finely granular.
VENTER ( Fig. 15 View Fig D–E). Free sternites finely granular; coxae II–IV finely and uniformly granular; coxa I with longitudinal row of tubercles and smooth area corresponding to lace area of pedipalp.
CHELICERAE ( Fig. 17 View Fig A–B). Basichelicerite with row of large tubercles from posterior border to ectal side; movable finger with row of ten tubercles, fixed finger with two small basal tubercles and five large tubercles decreasing in size from basal to distal part of finger.
PEDIPALPS ( Fig. 17 View Fig C–F). Trochanter with strong ventral process. Femur with pronounced dorsal keel formed by row of tubercles, with ventral row of twelve setiferous tubercles and mesodistal process. Patella with mesal keel without tubercles but with distal process. Shallow slit along tibia mesal surface, separating dorsal and ventral sides.
LEGS ( Figs 16B View Fig , 17 View Fig G–J). Coxa IV granulated, with large clavi inguines, larger in females. Trochanter IV with small retro-distal apophysis. Femur IV substraight, with two longitudinal ventral rows of tubercles increasing in size in distal part. Patella IV substraight, with small setiferous tubercles. Tarsal counts: 6–6/11–10/6–6/7–7.
COLOR ( Fig. 15 View Fig ). Body and appendages color background 51 (Deep Orange) mottled in 44 (Dark Reddish Brown), ladder mask 104 (Pale Greenish Yellow). Trochanters and tarsomeres 67 (Brilliant Orange Yellow).
GENITALIA ( Fig. 18 View Fig ). VP of penis subrectangular, narrower basally, with distal border concave; dorsal apophysis of glans subsquare to rounded, wattle of stylus long. Shapes and organization of macrosetae as follows: MS C1–C2 large, curved and flattened; MS D1–D2 large and straight; MS A1–A2 large, straight, cylindrical and located in basal middle of ventral plate; MS B and MS E1–E2 ventral, very small and immersed in microsetae. MS B most basal. Microsetae confined to lateral margins, from corners to base, of VP.
Variation
Right tubercle of the posterior margin may be absent in some specimens. Tarsal counts: 6; 10–13; 6–7; 7–8. Variation of measurements is given in Table 2 View Table 2 .
Female
With larger clavi inguines and longer coda than males. Males with thicker basitarsus (but not notably swollen) ( Fig. 16B View Fig ).
Distribution
Only known from type locality, in the WWF ecoregion Magdalena Valley montane forests (NT0136), tropical and subtropical moist broadleaf forest biome, in Santander Department ( Fig. 33 View Fig ).
