Identification. Our males of L. recurvus can be recognized by the presence of a rounded gibbosity on the venter of abdominal segment VIII, in addition to a posterior curved spine-like projection. Both males and females have the mesopleuron brown with a lighter stripe of variable size ( Fig. 6C) ( Nieser and Melo 1997).
