Lamponidae

Lamponidae is a family of spiders first formally described by Eugène Simon in 1893. This family is predominantly found in Australia, with the vast majority of its approximately 200 described species being endemic to the continent. The family is diverse, encompassing 23 genera, each with unique distributions and characteristics.

Geographic Distribution and Genera

The primary stronghold of Lamponidae is Australia, but its reach extends to neighboring regions. The genus Centrocalia, for instance, is entirely endemic to New Caledonia and the Loyalty Islands. In contrast, two species within the genus Lampona, namely L. cylindrata and L. murina, have established populations in New Zealand, where they have become commonly known as 'white-tailed spiders'. Further extending its distribution, Lampona papua is endemic to New Guinea, a region where two otherwise Australian species, Centrothele mutica and Lamponova wau, also occur, highlighting a shared biogeographical history.

The family's genera are broadly categorized into three subfamilies: Centrothelinae, Lamponinae, and Pseudolamponinae. Within these subfamilies, genera such as Asadipus, Bigenditia, Centroina, Centsymplia, Graycassis, Longepi, Notsodipus, Prionosternum, Queenvic, Lamponata, Lamponega, Lamponella, Lamponicta, Lamponina, Lamponoides, Lamponusa, and Platylampona are primarily found in Australia. Paralampona and Pseudolampona also have distributions that include Tasmania, underscoring the family's significant presence across the Australian landmass and its associated islands.
