One new species Savarna kraburiensis sp. n. (♂♀) is reported from southern Thailand.
Taxonomy, morphology, pholcidae, southeast Asia
The small genus Savarna Huber, 2005 only contains three species: Savarna baso (Roewer, 1963) from Sumatra, Indonesia, S. tesselata (Simon, 1901) from Malaysia, and S. thaleban Huber, 2005 from Thailand (
Specimens were examined and measured with a Leica M205 C stereomicroscope; details were studied with an Olympus BX51 compound microscope. Male and female copulatory organs were examined and illustrated after they were dissected from the spiders. Epigynes were removed and treated in 10% warm solution of potassium hydroxide (KOH) before illustration. Type specimens were preserved in 75% ethanol solution. Photographs were taken with an Olympus C7070 wide zoom digital camera (7.1 megapixels) mounted on a Leica M205 C stereomicroscope. The images were assembled using Helicon Focus 3.10 image stacking software. All measurements are given in millimeters unless noted otherwise. Leg measurements are shown as: Total length (femur + patella + tibia + metatarsus + tarsus). Leg segments were measured on their dorsal side. Type specimens are deposited in the Thailand Natural History Museum, Pathum Thani, Thailand.
