This species appears to be widespread on the Indian subcontinent and has typically been reported as Lepisiota capensis; specimens were collected by hand, beating vegetation and honey baiting.

Identification

The species is similar to Lepisiota modesta with which it shares its uniform black color and a medium-sized body. The distinguishing features include a combination of fine microreticulate sculpture on head and mesosoma, prominent propodeal spines and abundant erect setae on the body in L. mayri, versus a smooth and shiny body, reduced propodeal spines, and sparse erect setae in L. modesta.

Description

Worker

Head subquadrate; slightly longer than wide, wider posteriorly than in front; lateral and posterior margins convex, with rounded posterolateral corners; clypeus carinate in the middle; anterior clypeal margin complete and convex; eyes broadly oval, weakly convex, placed at the middle-line of head, covering about onethird of lateral cephalic margin; three small ocelli present; antennal scape surpassing posterior head margin by about one-third its length. In lateral view promesonotum convex, metanotum low, almost straight; mesometanotum demarcated; metanotal area distinct; mesometanotum constricted; propodeum armed with a pair of posteriorly diverging thick blunt spines; propodeal declivity steep. Petiole upright, with angular sides, dorsally emarginate, armed with a pair of nearly straight spines pointing upward.

Overall body shiny; head weakly microreticulate to smooth without sculpture; pronotum, metanotum and propodeal dorsum coarsely microreticulate; mesonotum weakly microreticulate, mesometanotal suture crossribbed; propleuron sometimes weakly longitudinally striate; mesometapleuron coarsely longitudinally striate. Black; scape and tarsi yellow brown.
