Figs 53–59

Type material. Holotype: male, ECUADOR: Morona Santiago: km 15 from Limón towards Gualaceo, 3.0090° S, 78.5024° W, elev. 1940 m, 15 July 2004, coll. Maddison, Agnarsson, Iturralde, Salazar, WPM#04–043 (UBC-SEM AR00148, QCAZ). Paratype: 1 female, ECUADOR: Morona Santiago: km 7 from Limón towards Gualaceo, 2.9962° S, 78.4558° W, elev. 1415 m, 12–15 July 2004, coll. Maddison, Agnarsson, Iturralde, Salazar, WPM#04–032 (UBC-SEM AR00149).

Etymology. Latin adjective foliosus (leafy), referring to the leaf-like marking on the dorsum of the abdomen.

Diagnosis. Similar to Ilargus macrocornis in the color and marking patterns, and the presence of guanine deposit in the eye area (Figs 53–54), but differs in the absence of a spur on the front surface of the male chelicera.

Description. Male (holotype, UBC-SEM AR00148). Carapace length 1.7; abdomen length 1.7. Chelicera: red brown. Palp (Figs 55–56): tibia and cymbium dark brown, other segments cream. Embolus long with a relatively wide spiral; proximal tegular lobe large; retrolateral sperm duct loop occupying more than half of bulb width; retrolateral tibial apophysis finger-like; ventral tibial bump absent. Measurements of legs: I 3.3, II 2.9, III 3.4, IV 3.6. Color in alcohol (Fig. 53): carapace dark brown, eye area with guanine deposit, behind eye area with a medial and two marginal yellowish stripes; abdomen dark brown, with many silvery white speckles and a large leaf-like mark medially; legs yellowish to dark brown.

Female (paratype, UBC-SEM AR00149). Carapace length 1.4; abdomen length 1.8. Chelicera (Fig. 57): red brown. Measurements of legs: I 2.4, II 2.2, III 2.6, IV 3.2. Epigynum (Fig. 58): window large; median septum relatively narrow; opening to copulatory duct at each side of median septum anteriorly. Vulva (Fig. 59): copulatory duct slightly convoluted; spermatheca almost stomach-shaped. Color in alcohol (Fig. 54): similar to that of male, but first two pairs of legs lighter in color than those of male.
