Remarks	A secretive nocturnal species.
Similar Species	Differs from all other species of Vincentia in having a very long caudal peduncle and mostly cycloid (smooth) scales on the body.
Etymology	The specific name macrocauda is from the Greek macros (= long) and the Latin cauda (= tail) in reference to the elongate caudal peduncle of this species.
