Leptogenys strena Zhou, 2001 |
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.
