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.
