Figs 31–33

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 AR00142, QCAZ).

Etymology. Latin elongatus (elongated), referring to the elongated male palpal tibia.

Diagnosis. Similar to Ecuadattus napoensis in color pattern and markings, but differs in the darker colored second, third and fourth legs, the relatively large dark markings on dorsum of the abdomen ( Fig. 31 ); the long male palpal tibia, the highly reduced embolic disc, and the narrower palpal bulb ( Figs 32–33 ). This species differs from E. typicus in the indistinct proximal tegular lobe and reduced embolic disc of the male palp ( Fig. 32 ).

Description. Male (holotype, UBC-SEM AR00142). Carapace length 2.7; abdomen length 3.1. Chelicera: red brown, back surface with a depression. Palp ( Figs 32–33 ): yellow brown. Embolic disc highly reduced; embolus short and slightly curved; palpal tibia long; retrolateral tibial apophysis long and finger-like; ventral tibial bump absent. Measurements of legs: I 5.7, II 4.8, III 5.7, IV 5.7. Color in alcohol ( Fig. 31 ): carapace brown, eye area with guanine deposit, posterior eye area with a narrow yellowish stripe, lateral margins behind eye area with yellowish stripes; abdomen light sandy yellow, with a pair of dark patches and some obscure markings; first leg brown, the other legs sandy yellow to brown.
