Selenogyrus austini is a theraphosid spider. As of February 2016, it is a member of the selenogyrinae. It is native to Sierra Leone.[1]
The specific name "austini" is in honour of the collector of the type specimens, Mr. E. E. Austin.[1]
S. austini has a characteristic crescent-shaped layout of the granules on the labium, and also has unique layout of the labio-sternal "mounds": the anterior pair being larger than in other species. It also has relatively stout stridulatory clavate ("club-shaped" [2]) setae on the chelicerae. The spermathecae are quite narrow at their base, and the clypeus is small but not absent. It is 41mm in length. It is uniformly brown.[3]
