Nothing is known about the biology of this species.

Identification

Lattke (2004) - There are only two species of Gnamptogenys with white-tipped antennae: Gnamptogenys albiclava and G. lucida. G. albiclava, another Solomon Island endemic, is larger (HL > 1.00; WL > 1.50 mm) and has a lower petiolar node and a longitudinally costulate mesonotum and lacks a denticle or lobe on the metacoxa. G. lucida has more globulose eyes than G. albiclava, with relatively larger ommatidia. The mandibles of G. lucida are not as slender as in G. albiclava and the petiolar node of G. lucida is more compressed.

Biology

Not much is known about the the biology of Gnamptogenys lucida. We can speculate that the biology of this species is similar to other species of the genus. Gnamptogenys are predatory ponerine ants that inhabit tropical and subtropical mesic forests. Nesting is typically at ground level in rotten wood or leaf litter. Some exceptions include species that are arboreal, a dry forest species and species that nests in sandy savannahs. Colony size tends to be, at most, in the hundreds. Queens are the reproductives in most species. Worker reproduction is known from a few species in Southeastern Asia. Generalist predation is the primary foraging/dietary strategy. Specialization on specific groups (millipedes, beetles, other ants) has developed in a few species.

Castes

Queen and male are unknown.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.

Lattke (2004) - Antenna bicolored with four apical segments white and the rest ferruginous. Promesonotal suture and metanotal sulcus both impressed as fine transverse lines, rest of mesosomal dorsum smooth. Postpetiolar process forming two contiguous convexities with brief posteromedian carina in ventral view. Metacoxal dorsum armed.
