Distribution.

Peninsular Malaysia.

Symbiotic hosts.

Leptogenys distinguenda and Leptogenys mutabilis .

Diagnosis.

This species is closely similar to Maschwitzia watanabei in general appearance, but is distinguished from it by the pronotum being narrower around the posterior margin and the aedeagus being different in shape, especially with the apical part of the median lobe being strongly widened apically and not excavated paramerally.

Comments.

Two specimens were collected for the first time from the end of a migration column of Leptogenys mutabilis (new host record).
