Comments: Flores and Brandon (1992) noted the absence of characters that unequivocally diagnose SIREN INTERMEDIA TEXANA; they concluded that TEXANA is an invalid taxon and placed it in the synonymy of S. I. NETTINGI. Pending further taxonomic data, the taxon formerly known as S. I. TEXANA is tracked in this database as SIREN INTERMEDIA POP 1.
