Dermatobranchus (Gosliner & Fahey, 2011)

Tibiriçá, Yara, Pola, Marta & Cervera, Juan Lucas, 2017, Astonishing diversity revealed: an annotated and illustrated inventory of Nudipleura (Gastropoda: Heterobranchia) from Mozambique, Zootaxa 4359 (1), pp. 1-133 : 90-91

Dermatobranchus sp. 1

( Figure 28 K )

Material examined. Seven specimens. ZMBN105608, 7 spcs., PPSA, 28 may 2015, 15– 22m, 6–12mm, collected by Y. Tibiriçá & M. Malaquias.

Habitats. Tropical coral reef.

Occurrences. Pemba.

Geographic distribution. Indo-west Pacific. Philippines (Gosliner et al. 2015) and Mozambique.

Remarks. This undescribed species is externally similar to Dermatobranchus sp. 11 in Gosliner et al. (2015, pag. 303) and is likely to represent the first record to the Indian Ocean. Nevertheless, the specimens from Mozambique lack the yellow line on the rhinophores and the dorsal lines are ticker. Another similar species is Demartobranchus albus (Eliot, 1904) but the specimens from Mozambique lack the prominent orange ridges typical of D. albus .
