Etymology. The specific epithet is taken from the Kichwa language and represents the combination of the two words, “yana” (black) and “chanka” (legs).

Diagnosis. Females are diagnosed by their colour pattern ( Fig. 23 View FIGURES 23 – 24 ); from L. gaujoni by their golden brown abdomen, black in the latter, and from L. quori by their black legs with brown tarsi ( Fig. 23 View FIGURES 23 – 24 ), light brown with dark bands in the latter ( Fig. 41 View FIGURES 41 – 43 ). Furthermore females are distinguished by their internal genitalia with numerous vesicles medially on short to elongated stalks ( Figs. 26, 27 View FIGURES 25 – 29 ). Males are distinguished by their overall black coloration, from L. gaujoni by their black carapace without yellow setae ( Fig. 24 View FIGURES 23 – 24 ); from L. quori by their black and curved embolus ( Fig. 28 View FIGURES 25 – 29 ), straight and light brown in the latter species ( Fig. 44 View FIGURES 44 – 47 ).

Natural history. The holotype female was collected in a 40 x 30 cm web approximately 1.5m from the ground in a secondary subtropical forest. The web was attached to a palm tree ( Phytelephas macrocarpa ), the base was made of dead palm tree leaves. Other specimens where collected in palm tree from 1m up to 6m high ( Fig. 49 View FIGURES 49, 50. 49 ), and one was collected at ground level.
