Female: unknown

Larva: unknown

Affinities: Amphinemura konplongensis is similar to A. divergens and to A. ningxiana Li & Yang, 2011 in having the tip of the epiproct bearing two strongly sclerotized processes which diverge; these are however much thinner than in A. divergens and A. ningxiana . Additionally, A. komplongensis has two ventral lateral processes, similarly shaped, that are absent in A. divergens and A. ningxiana .

Etymology. The species name refers to the town of Kon Plong (Kon Tum Province, Central Vietnam), the locality of which A. konplongensis was collected.
