GENUS HOMOIODORIS BERGH, 1882

Homoiodoris Bergh, 1882: 222–223 . Type species: Homoiodoris japonica Bergh, 1882 .

Remarks

Bergh (1882) described Homoiodoris , based on Homoiodoris japonica Bergh, 1904 , as very similar to Archidoris . Homoiodoris is characterized by having a depressed body with the dorsum covered with large tubercles. The tubercles around the rhinophoral and branchial sheaths are very large and apparently distinct from the rest. The oral tentacles are short and thick with a lateral groove. Internally, the labial cuticle is smooth and the radula is composed of simple hamate teeth, the prostate is large and the vagina is armed with hooks.

Homoiodoris appears to be very similar to Doris , but in the original description ( Bergh, 1882), there is not enough information about other features of this genus, such as the shape of the anterior border of the foot, to permit a definitive conclusion. Unfortunately the type material of Homoiodoris japonica could not be located at ZMUC and is presumed lost. Major differences between Homiodoris and Doris are the presence of a large prostate and vaginal hooks in Homoiodoris .

Homoiodoris novaezelandiae ( Bergh, 1904) is clearly a species of Hoplodoris (see above). There are no more species assigned to this genus.
