Basal tibial apophysis with proximally directed hook (fig. 428); embolus restricted to retrolateral side of bulb, with narrow, sinuous, distally directed tip, prolateral portion of median apophysis short, reaching only to prolateral edge of embolus (fig. 427).
FEMALE: Total length 14. Coloration as in female of
L. arcoona
. Leg spination: femora I–IV d101; tibiae III v220; metatarsi: I, II v220; III v200; IV v1p00.
