The type specimens of Mastigodiaptomus albuquerquensis patzcuarensis are labeled as PzType. A1 Post L = A1 length (posterior or anterior to the furcal rami); Pros L = prosomal length; Total L = total body length; UroL_NOFu = urosomal length without Fu; L GenSom = genital double-somite length; Pros1 L = first prosomite length; UroL = urosomal length with Fu; Fu L = furcal rami length; and L/W Rstrm = ratio of rostral spines.
