Identification

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

Biology

The type material was found in the nest of a Myrmica alaskensis nest. It was located in a rotten, moist tree trunk. The trunk was 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.
