Figures 206–209 ; Map 22

TYPE: Female holotype taken in pitfall trap 6.8 km S Binda Boudna Hill, 298279S, 1368139E, South Australia (Oct. 7, 1995) ; deposited in SAM ( N1997 /144) .

ETYMOLOGY: The specific name is a patronym in honor of Mr. David Hirst of the South Australian Museum, who first suggested the pairing of these males and females.

DIAGNOSIS: Males resemble those of L. eba but have a distinct basal protrusion on the ventral surface of the palpal femur (fig. 207); females also resemble those of L. eba but have an anteriorly widened epigynal midpiece and relatively shorter posterior portions of the spermathecae (figs. 208, 209).

MALE: Total length 6.8. Abdominal dorsum as in L. cylindrata ; anterior femora darkened distally, anterior tibiae darkened laterally, posterior patellae and tibiae dark­ ened laterally. Palpal femur with small, rectangular basal protrusion on ventral surface; retrolateral tibial apophysis with retrolaterally directed protrusion below tip (fig. 207); tegulum moderately expanded, reaching to about one­third of tibial length; embolar base short, wide, tip arched (fig. 206).

FEMALE: Total length 6.9. Coloration as in male. Epigynum with tongue­shaped midpiece extending full length of spermathecae, midpiece elevated anteriorly, level with remainder of cuticle posteriorly (fig. 208); spermathecae bipartite, with large anterior portions (fig. 209).
