Homoeomma (eyelike, from Ancient Greek ὅμοιος, like, and ὄμμα, eye) is a genus of South American tarantulas that was first described by Anton Ausserer in 1871.{{cite book |last1=Ausserer |first1=Anton |author1-link=Anton Ausserer |title=Beiträge zur Kenntniss der Arachniden-Familie der Territelariae Thorell (Mygalidae Autor) |date=1871 |location=Vienna |page=210 |url=https://archive.org/details/biostor-128324/page/210/mode/2up}} It is considered a senior synonym of Calopelma, Butantania, and of Cyclothoracoides. These tarantulas are usually quite small and usually burrow a few centimeters under a rock or log.{{Cite web |last1=Montenegro |first1=Rubén |last2=A.

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.

Species
