Of a collection of ten opisthobranch species (Mollusca: Gastropoda) from South Australia, three are described as new:
Haminoea maugeansis (Atyidae),
Neodoris subaustralis and
Aphelodoris lawsae (Dorididae), and one is a new record for the State :
Chromodoris tasmaniensis Bergh, 1905 (Dorididae). A study of the genus
Aphelodoris Bergh, 1879, in south-eastern Australia indicates six distinct species, of which two are named,
berghi Odhner, 1924, and
varia (Abraham, 1877), and four are described as new :
lawsae, rossquicki, juliae and
greeni. According to the literature,
Aphelodoris in Australia differs from other species of the genus in that the insemination duct between the female gland mass and the spermatheca is divided into a true small uterine duct and a wide terminally dilated large uterine duct. The spermatocyst is attached to the terminal dilation of the large uterine duct.
