External morphology

Body elongate, narrow, background colour white with black marks all along but most concentrated in the head area. Rhinophores black with white tips. Cerata with tubercles, apical part black.

Ecology

Specimens were found at shallow depths where there was an influx of fresh water, on rocks and hydrozoans, possibly Obelia spp. , feeding and laying large, short, linear, white egg masses (very different from the characteristic egg masses of the genus Doto , with an ‘S’ shape) at the bottom of the colony. Found to be more active at night.

Distribution

Corsica ( Ortea and Bouchet 1989); Italy ( Chiarore et al. 2019); Spain: Spanish Levantine coast (this study), Mallorca (GROC 2009–2021), Catalonia (this study); France (this study).

Remarks

This species is easily distinguished from Doto conspecifics by the presence of black rhinophores and small tubercles with a black dot in the cerata ( Ortea and Bouchet 1989).
