DIAGNOSIS: This species resembles L. lomond in having a subbasal knob on the palpal femur, but differs in having a shorter retrolateral tibial apophysis in males (fig. 91) and anterolateral epigynal invaginations in females (fig. 92). MALE: Total length 7.0. Abdominal dorsum with only posterior white spot clearly marked, with only vague indications of anterior white spots, venter palp gray, without markings; legs with posterior tibia distolaterally darkened. Palpal femur with distinct subbasal knob, retrolateral tibial apophysis situated near ventral edge of segment, accompanied by short, more dorsal apophysis (fig. 91); embolus with long, retrolaterally curved tip (fig. 90). FEMALE: Total length 8.8. Abdominal dorsum with four anterior white spots each almost rectangular, leg coloration as in male. Epigynum with v­shaped median septum separating anterolateral depressions marked by strong ridges (fig. 92); spermathecae with conical basal portion, rounded distal portion, situated between lateral invaginations (fig. 93).
