Lordomyrma

Members of the genus are small and inconspicuous, maintain colonies of modest size and tend to be shy and retiring when disturbed. Most species are denizens of the leaf litter in wet forest habitat, but some are known to nest and forage arboreally (Lucky and Sarnat 2008, Sarnat 2006).

Blaimer et al. (2018) found that Lordomyrma as presently defined is paraphyletic with respect to the genera Lasiomyrma, Propodilobus and Ancyridris. They also found that these four genera occur within a paraphyletic Mayriella genus-group (which includes Dacatria, Kartidris, Mayriella, Proatta and Tetheamyrma).

Identification
Morphologically, the genus is characterized by 12-merous antennae, a simple sting with straight apex, triangular mandibles with seven or more teeth decreasing in size from apex to base, well-developed propodeal spines, a bicarinate clypeus and elongate frontal carinae. All known Asian species and most others have well-defined antennal foveae also (Bolton 1994, Taylor 2009, 2012, Lucky and Sarnat 2010). This morphological interpretation, however, does not apply to all of the described species within the genus, nor does it exclude taxa which belong to morphologically similar genera. Consequently, assigning species to Lordomyrma is problematic, and probably a number of taxa related to Lordomyrma await shuffling (Shattuck 1999, Branstatter 2009, Taylor 2009, 2012, Lucky and Sarnat 2010).

Fossils
Fossils are known from: (an unidentified species, Wang et al., 2021).

Biology
Funnel-shaped entrances recorded in a nest from Danum Valley, similar in shape to Malagidris sofina.
