ETYMOLOGY: The specific name is a noun in apposition taken from the
type
locality.
DIAGNOSIS: Males and females have not been collected together, but are matched here because of their similar sternal modifications. Males have a less dramatically elevated sternum than do those of
L. forceps
or
L. ser pentine
(fig. 341); females have a presumably distinctive epigynal midpiece (fig. 336).
MALE: Total length 3.6. Abdominal dorsum gray, with white markings restricted to tiny spot above spinnerets, four circular muscle impressions, and lateral lines; legs brown, unmarked. Palpal femur short, thick, unmodified; tibia without retrolateral apophysis, with slight retrodistal excavation (fig. 335); cymbium not basally excavated; tegulum not extending beyond tip of tibia, but with pronounced bulge on prolateral side; embolus with long, arched tip (fig. 334).
FEMALE: Total length 4.2. Coloration as in male. Epigynum with narrow, scapelike median plate extending from anterior margin for about twothirds of epigynal length (fig. 336); spermathecae bipartite, posterior portions curled (fig. 337).
