Type; Envelope lists this as a type of Physodon mulleri. Eschmeyer states, "laticaudus, Scoliodon Mller [J.] & Henle [F. G. J.] 1838:27, 28, [Pl. 8] [Systematische Beschreibung der Plagiostomen; ref. 3069] India. Holotype (unique): ZMB 7830 (dry). Non-types: MNHN 0000-1123 (1), 0000-1041 (1), 0000-1066 (3), 0000-1122 (1). Type information: Bertin 1939:69 [ref. 20739], Paepke & Schmidt 1988:167, 168 [ref. 21041]. The description of this species on reset pages 27-28 printed in 1839 and to replace 27-28 of 1838 are based on the stuffed specimen (ZMB 7830) and 6 specimens in Paris; the original description in 1838 was based only on the ZMB specimen and it is therefore the unique holotype. The lectotype designation of a MNHN specimen by Springer 1964 is not valid; see remarks in Paepke & Schmidt 1988:167, 183 [ref. 21041]."
