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.
