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

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 (
