Discussion
.
Enithares ripleyana
was described from the island of Bacan, and previously known only from there as a putative endemic. The new records presented here demonstrate that the species in fact occurs more widely, also occupying the islands of Halmahera,
Ternate and Tidore
. It thus appears to be endemic to the northern Molucca islands as a whole. The species is easily recognized by the backward angling apex of the PL in the male genitalia, which is often visible externally without dissection.
