Specimen Label


This species is a social parasite in the nests of Myrmica scabrinodis and possibly Myrmica sabuleti (the identity of the latter host is currently uncertain). It is apparently workerless as no workers have yet been found. One parasitized host nest found at an altitude of 1400m, living under a stone, in a shaded clearing in a Pinus nigra wood. (Radchenko and Elmes 2003)

At a Glance • Workerless Inquiline  



A member of the laurae group. M. laurae well differs from most other socially parasitic Myrmica species by combination of the following features: eyes in both sexes with conspicuous hairs, length of the longest hairs 0.035 (queens) - 0.040 mm (males); generally a very hairy species; cubital cell on forewings closed and not partly separated by short vein; males with 12-jointed antennae, antennal scape long and slender, feebly curved at the base; antennal scape of queen not angulate, gradually curved at the base, but with distinct narrow longitudinal ridge. (Radchenko and Elmes 2003)

When Emery (1907) described M. laurae it was presumed to be a social parasite though its host was unknown. Mei (1987) identified the host of M. samnitica (a junior synonym of M. laurae) as Myrmica sabuleti. However, in the non-type series Mei collected from Abruzzo and Lazio, the specimens mounted with them as hosts were Myrmica scabrinodis. The worker specimens of these M. scabrinodis have relatively large scape lobes and could easily be mistaken for M. sabuleti, or alternatively, it is quite possible that M. laurae could use several different host species as does Myrmica karavajevi.
