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

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.


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 (47°40′30″N 70°46′30″W / 47.675°N 70.775°W / 47.675; -70.775). This area is subartic, dominated by black spruce and a ground cover of caribou lichen.

Type Material

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.
