[Note: although Myrma antedates Polyrhachis, the former has been treated as a subgenus of the latter since Forel, 1917: 251 (see Hung, 1967b: 396 for history). Dorow et al., 1997: 236, proposed the precedence of Polyrhachis over Myrma and that precedence was established by the ICZN (Opinion 1919) 1999: 92.]
