Lasiodora is a genus of tarantulas that was first described by Ludwig Carl Christian Koch in 1850. They are often very large; body lengths of up to , including the legs, are not unusual. They are found in South America, including the countries of Brazil, Bolivia, Costa Rica, Argentina and Uruguay.
Diagnosis
This genus can be distinguished from other tarantulas by the presence of hairs used for stridulation on the upper area of the coxae of leg 1 and 2. Males also own a triangular keel below the apex of the palpal bulb, females also have a sclerotized (hardened by sclerotin) area between the two sections of the spermathecae.
