Hapalopus
Hapalopus is a genus of tarantulas that was first described by Anton Ausserer in 1875.
Diagnosis
They own a ring like keel on the palpal bulb, the tibial apophysis with convergent branches and a spermatheca having a membrane like base. They also lack stridulatory hairs and they own numerous labial cuspules. Specimens are further differentiated from the closely-related Notahapalopus genus by a single round spermathecal receptacle, which is Y-shaped in Notahapalopus.Species
