Acrogomphus minor has distribution from Thailand to Peninsular Malaysia. However, so far only one record has been documented from Peninsular Malaysia - of which the species was being described by Laidlaw (1931). The Peninsular Malaysia old specimen (holotype) was actually collected by H.M. Pendlebury somewhere in Kuala Lumpur in July 1922.
Lately, I caught one
A. minor specimen from Perak. So, this will be the second record (specimen) of
A. minor from Peninsular Malaysia in 90 years!
