Synonyms[1]
  • Butantania Mello-Leitão, 1935[2]

  • Cyclothorax Mello-Leitão, 1923

Homoeomma is a genus of South American tarantulas that was first described by Anton Ausserer in 1871.[5] It is considered a senior synonym of Calopelma,[3] Butantania,[2] and of Cyclothoracoides.[4] These tarantulas are usually quite small and usually burrow a few centimeters under a rock or log.[6]

Diagnosis

Males of this genus can be distinguished by the tile-like apophysis on the base of the palpal bulb, and the embolus being in an obtuse angle, in relation to the bulb. Males also have a flexion of the metatarsus 1, which is between the branches of the tibial apophysis. Females can be distinguished by the spermatheca morphology, which lacks constriction in the apex.[6]
