REMARKS

This species is similar to Dactylonia monnioti ( Bruce, 1990) from which it differs in not having a subdistal ventral tooth on the rostrum. None of the present specimens has a small ventral subdistal tooth on the rostrum as in the holotype specimen of D. monnioti ( Bruce, 1990) .

The species has only been recorded from Bali and Ambon, Indonesia. These are the first records of the species from Papua New Guinea.

The species has been recorded from the genus Plurella , but without the identification of the host to species level. This is the first record of the species from Plurella monogyna .
