Abstract
We recovered well-preserved Triassic radiolarians from a thin-bedded limestone exposed at Khao Chiak, near Phatthalung, southern Thailand. This radiolarian fauna is associated with conodonts indicating a latest Spathian to earliest Anisian age and composed of families such as "Paleozoic-type" Entactiniidae, Actinommidae, spicule-type Palaeoscenidiidae, and acanthodesmid Nassellaria. We propose a new genus and four new species herein. The occurrence of the genera Entactinia Foreman and Polyentactinia Foreman is the first record from the Triassic.
