'''''Pancorius crassipes''''' is a species of jumping spider found from Thailand to Japan.<ref name=inat>{{cite web |title=Pancorius crassipes |url=https://www.inaturalist.org/taxa/360385-Pancorius-crassipes |website=iNaturalist |access-date=2025-08-25}}</ref> Originally described as ''Plexippus crassipes'' by Ferdinand Karsch in 1881, the species was later transferred to the genus ''Evarcha'' before being placed in its current genus ''Pancorius'' in 2001.<ref name="logunov2001">{{cite book |last1=Logunov |first1=D.V. |last2=Marusik |first2=Y.M. |date=2001 |title=Catalogue of the jumping spiders of northern Asia (Arachnida, Araneae, Salticidae) |publisher=KMK Scientific Press |location=Moscow |pages=150}}</ref>
== Distribution == ''Pancorius crassipes'' is widely distributed across Eastern and Southeastern Asia, with confirmed records from China (including Taiwan), Japan, South Korea, and Vietnam.<ref name="wsc">{{cite web |title=World Spider Catalog version 26: Pancorius crassipes (Karsch, 1881) |url=https://wsc.nmbe.ch/species/31463|website=World Spider Catalog |publisher=Natural History Museum Bern |access-date=2025-08-25}}</ref> The species has also been reported from Poland, though this may represent a recent introduction rather than an established population.<ref name="wsc"/>
== Taxonomy == The species has undergone several taxonomic changes since its original description. Karsch first described it as ''Plexippus crassipes'' in 1881.<ref name="karsch1881">{{cite journal |last=Karsch |first=F. |date=1881 |title=Diagnoses Arachnoidarum Japoniae |journal=Berliner Entomologische Zeitschrift |volume=25 |pages=35–40}}</ref> In 1971, Jerzy Prószyński and Wanda Staręga transferred the species to the genus ''Evarcha'',<ref name="proszynski1971">{{cite journal |last1=Prószyński |first1=J. |last2=Staręga |first2=W. |date=1971 |title=Pająki-Aranei |journal=Katalog Fauny Polski |volume=33 |pages=1–382}}</ref> where it remained until Logunov and Marusik moved it to ''Pancorius'' in 2001.<ref name="logunov2001"/>
The transfer to ''Pancorius'' was based on several diagnostic characters that distinguish this species from typical ''Evarcha'' species, including its large elongated body, densely haired body and legs, relatively long spinnerets, and the presence of a hair pencil beneath the palpal median apophysis in males.<ref name="logunov2001"/>
== Description == ''Pancorius crassipes'' is a relatively large jumping spider. Males measure 10–11 mm in total body length, while females are slightly larger at 12–13 mm. The species has a robust, elongated body that is densely covered in hair, giving it a distinctly hairy appearance compared to many other jumping spiders.<ref name="karsch1881"/>
The carapace is dark brown to black with a distinctive pale stripe running down the center. The legs are relatively thick and robust, which is reflected in the species name "crassipes" meaning "thick-footed". The abdomen shows various patterns of brown and pale markings that can vary between individuals.<ref name="karsch1881"/>
