Checked: verified by a taxonomic editorSynonymy Nephasoma (Nephasoma) diaphanes diaphanes (Gerould, 1913) and Nephasoma (Nephasoma) minutum (Keferstein, 1862) are two different species which can be differentiated when you have ripe specimens in the sample.
The first species is dioecious, whereas the second is hermaphroditic. Cutler also used as a criterion the origin of the sample: deep-water for the first vs. shallow water for the 2nd species. And the 1st species is almost cosmopolitan whereas the 2nd species is restricted to NE Atlantic waters. Otherwise both species are difficult to separate since they share the same morphological characters

Checked: verified by a taxonomic editorSynonymy Murina & Sorensen (2004) pp. 285-6 did not accept the proposal of Cutler (1994) and both names were considered as synonymous by them. In general: WoRMS is following Cutler (1994) proposals.
