Distribution. Ecuador, Santo Domingo de Las Tsáchilas .

Natural history. The holotype female was collected in a foothill forest at 884m elevation. The web of approximately 60 x 40 cm was along a vertical dirt talus or landslide 6m from the ground, and the retreat was concealed in a soil crevice. The only specimen collected lives in sympatry with L. zaia and L. quori , but was found in a somewhat distinct microhabitat.
