Comparing the Following Taxa
Leptomyrmex aitchisoni Smith and Shattuck, 2009
Head relatively elongate (CI less than 79); antennal scape relatively long (SI > 170) and extending beyond the vertex of the head by greater than half their length; pilosity short adpressed hairs; palps relatively short, failing to reach the posterior of the head capsule.
Leptomyrmex burwelli Smith and Shattuck, 2009
Scapes long (SI > 170); pubescence of short, sparse adpressed hairs; dorsum of petiolar node strongly convex in anterior view; anterior mesonotum with a strongly raised bump. This species can readily be separated from the sympatric
by the distinctively humped anterior mesonotum.
Leptomyrmex cnemidatus Wheeler, 1915
Leptomyrmex darlingtoni Wheeler, 1934
Leptomyrmex dolichoscapus Smith and Shattuck, 2009
Head elongated head (CI less than 79), antennal scape very elongated (SI greater than 220) and extending beyond the vertex of the head by 2/3 their length. Palps very long. Anterior mesonotum with a weak "bump". Pilosity short adpressed hairs. This species is sympatric with
from which it is readily distinguished by its extremely long scapes.
Leptomyrmex erythrocephalus (Fabricius, 1775)
Leptomyrmex garretti Smith and Shattuck, 2009
Scapes long (SI > 174); pubescence short sparse and adpressed; petiolar node weakly convex in anterior view; anterior mesonotum without a raised hump. Sympatric with
it is more widespread than these and readily separated from them by the combination of normal length scapes and normal pilosity.
Leptomyrmex mjobergi Forel, 1915
Leptomyrmex nigriventris (Guérin-Méneville, 1831)
Leptomyrmex pilosus Smith and Shattuck, 2009
Palps elongated, extending well beyond the posterior margin of the head capsule. Antennal scapes elongated (SI greater than 170) and extending beyond the vertex of the head by about half their length. Distinctive abundant pilosity consisting of shorter adpressed and longer decumbent hairs. Morphologically it is similar to
but is readily distinguished by the abundant pilosity on all surfaces.
Leptomyrmex ramorniensis Smith and Shattuck, 2009
Head relatively short (CI greater than 80); antennae relatively short (SI less than 150) and extending beyond the vertex of the head by less than half their length; palps short, not reaching the posterior of the head; hind tibial spurs with barbules longer than the width of the shaft. It differs from close relatives in having a shorter and wider head and relatively short antennae, palps and legs.
Leptomyrmex rothneyi Forel, 1902
Leptomyrmex ruficeps Emery, 1895
Leptomyrmex rufipes Emery, 1895
Leptomyrmex rufithorax Forel, 1915
Leptomyrmex tibialis Emery, 1895
Leptomyrmex unicolor Emery, 1895
Leptomyrmex varians Emery, 1895
Leptomyrmex wiburdi Wheeler, 1915
