This character is of specific level. 

Genus Phormictopus Pocock 1901: Phormictopus auratus Ortiz & Bertani 2005 - subapical keel (SA) serrated. 

Phormictopus cancerides (Latreille 1806) from Santo Domingo, Republica Dominicana - keels smooth (Pérez-Miles et al., 1996).

Bertani, 2000 examined Phormictopus cancerides (Latreille 1806) from Barahona, Republica Dominicana (from Rick West private collection) and Phormictopus cubensis Chamberlin 1917 from Cuba (from Museu Nacional do Rio de Janeiro, 13264) and recognized a presence of four keels: two prolateral keels (PS, PI), apical keel (A) and subapical keel (SA) constituted by denticulate row (DR). Author supposed that SA keel found as triangular apical tooth in genera Eupalaestrus, Lasiodora, Nhandu and Vitalius  is homologous with DR of SA keel found in P. cancerides and P. cubensis.
