Taxonomic History
- 2025 Euathlus sinapophysis Montenegro Vargas & Aguilera, 2025
- The ninth Euathlus from Chile. Its description forced an amendment to the generic diagnosis: the tibial apophysis of leg I, previously always present in the genus, is now recorded as one that "may be absent (only in E. sinapophysis)".
