Distribution This is the first record of the genus and species for the Amazon Region. The species was previously known from southern Colombia (Delsinne and Fernández 2011) and Ecuador (Salazar et al. 2015). This finding highlights the importance of studying ants in transition zones, as valuable information can be obtained about the distribution of species considered primarily Andean. Biology Unusual species, rarely collected. According to Delsinne and Fernández (2011), L. inusitatus inhabits mainly leaf litter and modified mandibles may be related to their being specialised hunter ants, although their prey is not known.
