Lamponina elongata , new species Figures 299–302 ; Map 35

TYPE: Female holotype taken in pitfall trap in Francois Peron National Park , 258509S, 1138369E, Western Australia (Oct. 12, 1994 – Jan. 18, 1995; N. McKenzie, J. Rolfe), deposited in WAM (96/1254) .

ETYMOLOGY: The specific name refers to the elongated pedicel.

DIAGNOSIS: Specimens can easily be distinguished from those of the other known Lamponina species by their relatively long pedicel, their relatively narrow, elongated fourth femora, and (usually) their relatively pale coloration (the legs are usually yellow, and the anterior half of the abdomen is usually white). Males resemble those of L. scutata in having an oblique constriction at roughly half the length of the ventral surface of the palpal femur, but have a ventrally less protuberant retrolateral tibial apophysis (figs. 299, 300). The female spermathecae are relatively long, and are often anteriorly divergent (figs. 301, 302).

NOTE: The males available from Victoria and the Northern Territory have the oval sclerites behind the epigastric furrow greatly enlarged, equalling in length about twothirds the length of the epigastric scutum; the palps, however, seems normal for the species, and one male from South Australia ( Yarna Station ) has an intermediate condition, with moderately enlarged sclerites .

MALE: Total length 8.3. Dorsum of abdomen white, with transverse gray stripe at about two­thirds its length, stripe extended posteriorly around posterior white spot, remainder of sides and venter white; coxae orange, other leg segments yellow. Palpal femur with slight ventral invagination at about half its length; tibia globose, with dorsodistally directed, thumb­shaped retrolateral apophysis, ventral edge of apophysis receding rather than protuberant (fig. 299); tegulum with pronounced posterolateral corner, embolus relatively short, evenly arched (fig. 298).

FEMALE: Total length 9.4. Coloration as in male. Epigynal midpiece relatively wide (fig. 300); spermathecae small, on long bases (fig. 301).
