Taringa millegrana, also known as Aporodoris millegrana, is a species of sea slug, a dorid nudibranch, shell-less marine gastropod mollusk in the family Discodorididae.
Alder and Hancock have described the new species according to preserved specimens. Alder's and Hancock's original text (the type description) reads as follows:
The length of preserved specimens of type material varies from 15 mm to 28 mm. The color of live specimen is brown-orange or dark violet-brown. The color of preserved specimens is yellow. There are light violet-brown rhinophores with yellowish white apex on the head. There are 120 μm long caryophyllidia covering the whole dorsal part of the body. There are also 80 μm long tubercules on the body.
This species occurs in European waters: British Isles, France, Tenerife, Spain, Mediterranean Sea.
Alder & Hancock (1854) mentioned the locality Torbay, England in their paper but the type locality should be Torquay according to the name on labels of type material.
