Taxonomic Notes

Say (1836) - original description: 5. M. dimidiata. Body pale yellowish: thorax somewhat tinged with piceous: wings with a very slight tinge of yellowish; discoidal cellule in length nearly twice its breadth ; separating nervure between the first and second cubital cellules abruptly ending at the middle of the usual length, being entirely wanting on the basal half.

Length over one fifth of an inch.

Weber (1947): Myrmica dimidiata Say from the United States was described as "body pale yellowish: thorax somewhat tinged with piceous" ... "length over one-fifth of an inch;" the omitted part of the description deals with the wings and is a purely generic diagnosis. The color of the body is that of no nearctic Myrmica female [queen] although the size might be that of any of the forms of Eastern America. It is unsatisfactorily synonymized with the type species of the genus since the actual specimen appears to be lost and it is impossible otherwise to correlate it with known forms.
