Etymology. The species name is a noun in apposition, invariable taken from the type locality, Maicu Reserve.

Diagnosis. Males and females most closely resemble those of K. turumanya ; males are distinguished by their long, spiraled embolus ( Figs 2A View FIGURE 2 , 7B, C View FIGURE 7 ), sinuous in the latter ( Dupérré & Tapia 2015: figs. 2, 3); females are differentiated by their long, spiraled copulatory duct leading to an oval receptacle ( Fig. 2C View FIGURE 2 , 7D View FIGURE 7 ), whereas the copulatory duct is short, not spiraled in the latter ( Dupérré & Tapia 2015: fig. 5).

CEPHALOTHORAX: Carapace pyriform, narrowing gradually anteriorly; shiny, light yellow-orange, fovea absent ( Fig. 1A View FIGURE 1 ); reticulated ( Fig. 3A View FIGURE 3 ). Sternum light yellow, suffused with purplish reticulated pattern, as long as wide ( Fig. 1B View FIGURE 1 ); rebordered with longitudinal grooves ( Fig. 3C View FIGURE 3 ). Endites light yellow, longer than wide, serrula present ( Fig. 4C View FIGURE 4 ); labium light yellow, rebordered, fused to sternum ( Fig. 3C View FIGURE 3 ). Clypeus vertical, height 0.11.

OPISTHOSOMA: Pear-shaped; dorsally uniformly turquoise-blue ( Fig. 1A View FIGURE 1 ) with long dark setae; ventrally turquoise-blue suffused with purplish pattern; with ~23 anteroventral ridges on the pars stridens, with pores plates ( Fig. 4E View FIGURE 4 ); colulus pentagonal ( Fig. 4F View FIGURE 4 ); spinnerets: AMS with one MAP and five PY; PMS with two CY; and PLS with four CY ( Fig. 5A, C View FIGURE 5 ).

Natural History. Males and females were collected sifting forest litter and extracted with a Berlese funnel. The species was found between 900–1159 m, in an evergreen foothill forest of the Cóndor Kutukú Cordillera (BsPa02) ( Aguirre et al 2013).
