Myrmecophily, in which insects live in association with ants for part or all of their life cycle, has been documented across a wide range of insect groups. Coleoptera, in particular, show a high frequency of myrmecophilous taxa, likely due to their hardened elytra and frequent occupation of ground-level microhabitats that facilitate interactions with ants (Parker, 2016). Within Carabidae, myrmecophily occurs in several lineages, with Paussinae and Pseudomorphinae being the most remarkable subfamilies. These two subfamilies exhibit morphological adaptations as symphilies and synechthrans, respectively, whereas in other carabid lineages, myrmecophilous traits occur sporadically. One such example is Lachnoderma asperum Bates, 1883, a member of the subfamily Lebiinae.
