Spalerosophis diadema cliffordi (Schlegel, 1837) – from Morocco to Egypt and Israel (Type locality: Tripoli, Libya)
Spalerosophis diadema diadema (Schlegel, 1837) – India, Pakistan (Type locality: near "Bombay", India)

Etymology

The subspecific name, cliffordi, is in honor of "M[onsieur]. Clifford Cocq van Breugel " who was Dutch consul at Tripoli,[2] probably referring to Jacques Fabrice Herman Clifford Kocq van Breugel (1799-1867).
