Figs. 17–21

Type material. Holotype male in the UBC­SEM with label: " ECUADOR: NAPO: Estación Biológica Jatun Sacha . S 1.067 W 77.617; 400 m el. Forest and nearby disturbed areas. 21–24 July 2004 Maddison, Agnarsson, Iturralde, Salazar. WPM#04­055"; "UBC­ SEM AR00003"

Molecular data gathered for this species by Maddison & Needham (2006) were obtained from several legs of the holotype male ( DNA voucher d124).

Etymology. The name refers to the habitat of mossy tree trunks.

Diagnosis. This brown species has a generalized salticid body form, but is distinctive among the neotropical fauna by its palpus with a round amycoid­like bulb, but having a prominent median apophysis ( Figs. 19–20 ).

Description. Male holotype: Carapace length 2.2, width 1.7, height 1.3; abdomen length 2.2. Approximate leg lengths 4> 1> 3> 2. Macrosetae on left tibia I P 0­1­1 V 2­2 ­2 R 0­ 1­1; right tibia 1 P 1­1­1 V 2­2 ­3 R 1­1­1. First metatarsus with four pairs of ventral macrosetae, although the terminal pair might be considered lateral. Second leg anterior tarsal claw with ca. 7 teeth, posterior with 6. Chelicerae: Three promarginal and two retromarginal teeth. Palpus ( Figs. 19, 20 ): superficially resembles an amycoid palpus, with embolus fixed to a round tegulum, but projecting from the ventral­retrolateral side of the tegulum is a prominent median apophysis. As in Galianora sacha , the retrolateral tibial apophysis is sharp and accompanied by dorsal and ventral lobes. Carapace with posterior lateral eyes on raised mounds compared to the fovea which lies in concavity. Colour: carapace dark brown to black except for pale central longitudinal stripe on thorax. Opithosoma medium brown with indistinct speckling above; venter black. The integument of the legs and carapace has a subtle rainbow iridescence, at least under alcohol.

Female: adult female unknown. Immature female: palpus with tarsal claw.

Specimens examined. Collected with the holotype were three juveniles.

Natural history. The juveniles were collected beating moss­covered branches and tree trunks in understory of lowland rain forest. The male holotype was collected by G. Iturralde on a tree trunk within the forest.
