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.
