Nothing is known about the biology of Leptogenys strena.

Identification

Zhou (2001) - Resembles Leptogenys lucidula but can distinguish from the latter by mandible with 5 teeth (the latter with 8~10 teeth); anterior clypeal border rounded, not angular; propodeal declivity longitudinally concave in meian surface, not truncate. Besides, the new species separated from the latter by much more hairs and much larger in size.

Head longer than broad, with straight sides and slightly concave occipital border. Mandible narrowly triangular, masticatory margin with 5 large teeth, with an interval between the 4th and the basal tooth. Median clypeus convex, with stout median carina. Antennal scape slightly extending beyond the occipital border. Eyes relatively small, situated in front of the midlength of the sides of head. Alitrunk stout, promesonotum slightly convex, promesonotal suture distinct; mesopropodeal suture slightly incised. Basal face of propodeum as long as the declivity which slightly concave in the median surface, conjunction of them rounded. Petiolar node thick, anterior face slightly convex, posterior face straight, dorsal border blunt rounded. Subpetiolar process semicircular. Constriction between basal two gastral segments distinct.

Mandibles with longitudinal striations; lateral of clypeus with fine transverse striations; head, alitrunk, petiole and gaster smooth and shining.

Erect and suberect hairs abundant on the entire body.

Color reddish brown; antennae and legs lighter.
