Material not physically examined. Unknown [but see Remarks under ‘ L. processionalis ’].

Literature. None. New record.

Localities. Lower Peirce Reservoir; Mandai Lake Road; Mandai Road; Nee Soon Swamp Forest.

Habitat/Ecology. This species appears associated mostly with primary and old/mature secondary forests, including swamp forest where a nest was found in a mud mound on waterlogged ground.

Remarks. This species is similar to L. iridescens , but may be distinguished from the latter by a few characters such as: 1) head in full face view more squarish, only slightly longer than wide (in L. iridescens distinctly longer than wide); 2) lateral margins of head in full face view evenly and broadly convex (in L. iridescens the sides are almost straight); 3) eye farther from lateral head margin in full face view (in L. iridescens the eye is about half the former distance from lateral head margin); 4) antennal scape relatively thicker across its entire length (more ‘flattened’ laterally) in proportion to head width.
