Taxonomy

The species was originally described by Eugène Simon in 1899 as Hyllus thorelli based on a male specimen collected in Sumatra.^[2] In 1984, Jerzy Prószyński transferred the species to the genus Pancorius.^[3]

Distribution

P. thorelli is endemic to Indonesia, where it has been recorded from Sumatra.^[1] Observations have also been made from Thailand, Malaysia and Borneo.^[4]

Description

The original description by Simon describes a male specimen measuring 8-10 millimeters in length. The cephalothorax is brownish-chestnut to blackish in color with reddish-brown pubescence on both sides and extending to the eye region. There is a white hairy border that is quite broad. The abdomen is blackish with a very broad central white hairy stripe near the apex, marked with small black spots arranged in two rows above this stripe.^[2]

The species is noted as being unusual for the genus due to its third pair of legs being much longer than the fourth pair, a characteristic reminiscent of spiders in the genus Pseudamycus.^[2]
