TYPE: Female holotype from North Point, Kapalga, 128259S, 1328229E, Northern Ter­

ritory (Nov. 11, 1979; R. Raven), deposited in QMB ( S34369 ).

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of L. walsh but can be recognized by the larger, longer retrolateral tibial apophysis and more globose tegulum (fig. 115); females also resemble those of L. walsh but have much larg­ er anterior bulbs on the spermathecae (fig. 117).

MALE: Total length 4.9. Abdominal dorsum with anterior and median pairs of white spots fused into narrow paramedian longitudinal stripes; anterior femora, patellae, and tibiae darkened throughout their length, posterior femora darkened distally, patellae darkened laterally, tibiae darkened distally. Palpal femur unmarked, unmodified; retro­ lateral tibial apophysis long, gradually narrowed distally (fig. 115); tegulum globose, extending to almost half of tibial length, embolus sharply narrowed below tip (fig. 114).

FEMALE: Total length 5.7. Abdominal dorsum with only median pair and posterior white spots, anterior pair obsolete; sides of femora, patellae, and tibiae darkened distally. Epigynum triangular, median plate invaginated on insides of lateral margins (fig. 116); anterior portion of spermathecae enlarged, bulbous (fig. 117).
