White-tailed Spider Lampona cylindrata (L. Koch, 1866)

(after Platnick 2000): Lampona cylindrata is very similar to L. murina and has often been confused with it in the past. Females are relatively easy to distinguish by spermathecal structure; the narrow, tubular, bulging spermathecae of L. cylindrata are quite different from the basally widened spermathecae with distinctly offset tips that are characteristic of L. murina. The epigynal fossa of L. cylindrata is also typically wider and more rounded than that of L. murina, with the outline of the spermathecae typically presenting a pair of circular spots just behind the posterior rim of the fossa. Differences in the male palpi are subtle; in L. cylindrata, the palpal femur is relatively long and narrow, and the retrolateral tibial apophysis is relatively long, relatively narrow at its base, and almost straight, whereas in L. murina the palpal femur is relatively short and thick, and the retrolateral tibial apophysis is relatively short, widened at its base, and distally curved. The medial portion of the membranous palpal conductor also differs between the two species, barely extending over the lateral portion of the conductor in L. cylindrata, but produced into a wide, rounded lobe covering the base of the lateral portion of the conductor in L. murina.

(after Platnick 2000): Male lectotype, in effect designated by L. Koch, 1873: 373–375, who removed the female paralectotype from this species by using it as the holotype of L. ruida, from Australia [as ‘‘Neuholland’’], no specific locality, NHM).
