Polyrhachis craddocki is so far known only from two localities separated by a distance of over 2600 km, with no material known from areas in between. All specimens from Brunei were collected during two successive visits to the KBFSC, apparently from a single colony trail on a tree trunk and surrounding vegetation just a few hundred metres from the base accommodation units. A thorough search of the surrounding areas to locate another P. craddocki colony was conducted on both occasions, with the help of the entomology staff of the Brunei Museum, but without success.

A member of the lamellidens group of the subgenus Polyrhachis. In spite of the geographical separation, the known specimens of this taxon are very similar and, apart from the generally larger size of specimens from Brunei (HL 1.81 – 2.00 versus HL 1.72 – 1.84 in syntypes from Myanmar), they are closely comparable in all other aspects.
