Fossil arachnids from the earliest Miocene Foulden Maar Fossil-Lagerstätte, New Zealand

Selden, P.A. & Kaulfuss, U., 28 May 2018. Fossil arachnids from the earliest Miocene Foulden Maar Fossil-Lagerstätte, New Zealand. Alcheringa 43, 165–169. ISSN 0311-5518. Fossil Arachnida from New Zealand are extremely rare and represented by some unidentifiable amber inclusions only. The first fossil arachnids from New Zealand to be described in detail are presented here, based on four compression fossils from the earliest Miocene Fossil-Lagerstätte at Foulden Maar, South Island. Two specimens are referred to Arachnida incertae sedis and Araneomorpha incertae sedis, respectively, whereas two specimens are mygalomorph spiders. One of these is placed in the Rastelloidina clade of Mygalomorphae, probably in the Idiopidae, which is represented in New Zealand by the extant Cantuaria. P.A.
