Type material. Holotype: male, ECUADOR: Morona Santiago: km 16 from Limón towards Gualaceo, 3.0060° S, 78.4997° W, elev. 2000 m, 12–15 July 2004, coll. Maddison, Agnarsson, Iturralde, Salazar, WPM#04–035 (UBC- SEM AR00150, QCAZ). Paratypes: 1 female, same data as holotype (UBC-SEM AR00151); 1 female, same data as holotype.

Etymology. The specific epithet is a patronym in honor of Dr. M. E. Galiano, who made great contributions in taxonomic studies of jumping spiders from the Neotropical region.

Diagnosis. Similar to Ilargus moronatigus in color and markings ( Figs 60–61 ), but can be distinguished by the large epigynal window, the presence of the wave-shaped ridges in the window ( Fig. 65 ), and the long and convoluted copulatory duct ( Fig. 66 ). Also differs from other Ilargus species by the shape of the male palpal bulb ( Fig. 62 ).

Description. Male (holotype, UBC-SEM AR00150). Carapace length 1.5; abdomen length 1.7. Chelicera: yellow brown. Palp ( Figs 62–63 ): yellowish to brown. Embolus long and coiled for about a circle; retrolateral sperm duct occupying about two thirds of bulb width; retrolateral tibial apophysis finger-like; ventral tibial bump absent. Measurements of legs: I 3.1, II 2.6, III 3.0, IV 3.5. Color in alcohol ( Fig. 60 ): carapace gray brown with indistinctive yellowish markings, eye area dark brown, behind eye area with a narrow sandy yellow stripe; abdomen brown sandy in color, with brownish markings and speckles; legs bisque, with gray brown annuli.

Female (paratype, UBC-SEM AR00151). Carapace length 1.6; abdomen length 2.0. Chelicera ( Fig. 64 ): yellow brown. Measurements of legs: I 2.8, II 2.6, III 3.1, IV 3.8. Epigynum ( Fig. 65 ): window large, with transverse wave-shaped ridges in the window; median septum relatively narrow; opening to copulatory duct at anterior margin of window. Vulva ( Fig. 66 ): copulatory duct long and convoluted, with accessory gland near the beginning; spermatheca almost kidney-shaped. Color in alcohol ( Fig. 61 ): similar to that of male, but abdomen dark brown with brown sandy markings and speckles.
