This parasite was discovered as part of a September 1965 ant biodiversity study in the southeastern portion of the Parc des Laurentides (now Grands-Jardins National Park) in Quebec. A queen and male were found in a Myrmica alaskensis nest.

One of two known parasites of Myrmica alaskensis. Both parasites are only known from queens and males. Francoeur (1984) provided a couplet for distinguishing M. lampra from the other parasite, Myrmica quebecensis

The type material was found in the nest of Myrmica alaskensis. The nest was located in a rotten, moist tree trunk on the ground of a slope facing south, between the Sainte-Anne-du-Nord river (Quebec) and a sand road, at an altitude of 2400 feet ( ). This area is subartic, dominated by black spruce and a ground cover of caribou lichen.
The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
The nest of the host-species was hollowed in a rotten and very humid tree trunk. The trunk rested on the ground of a slope facing south, between the Sainte-Anne-du-Nord river and a sand road, at an altitude of 2400 feet. The geographical coordinates of the place are 47°40'30"N latitude and 70°46'30"W longitude. Both specimens are deposited as types in the Provancher Collection of the Musee du Quebec, Laval University.
