Abstract

The spider genera Longissipalpus Wunderlich, 2015 and Pedipalparaneus Wunderlich, 2015 of the extinct family Pholcochyroceridae Wunderlich, 2008, are reported from mid-Cretaceous Kachin amber only. Members of both genera exhibit extremely elongated pedipalps. Here, two new species are described: Longissipalpus albistriatus sp. nov. and Pedipalparaneus protumidus sp. nov., both are endemic to Kachin amber. Detailed diagnoses and illustrations are provided, and their potential living habits are also discussed.
