(San Diego) | | | | N: | 2 | | | | Lg.: | | | (143) F: 4; (144) F: 4,3; {F: 4,00-4,30} | | | | Rem.: | Vervoort (1965, p.25, 26) considère, avec doute, cette espèce comme un synonyme de Phaenna spinifera . Park (1983 a , p.319) et Bradford & al. (1983, p.67) considèrent cette forme comme non valable, contrairement à Fleminger (1967 a).
