Description
Body coloration ranges from red to orange. Two crater-like depressions are arranged along the mid-dorsal line, with thin white lines extending laterally from each depression, though these may be inconspicuous in some specimens. Rounded red tubercles are scattered across the dorsum. The rhinophores and gills are red, with the rhinophoral and branchial sheaths distinctly serrated along their margins. The gill plumes are red centrally and become brownish ivory toward the periphery. Maximum recorded body length approximately 15 mm.Distribution
The type locality is Zavora, Inhambane Province, Mozambique. Originally recorded from the western Indian Ocean; subsequent records extend to the western Pacific including Malaysia, Papua New Guinea, Indonesia, and Japan (Amami and Okinawa regions).Etymology
The specific epithet zavorensis derives from "Zavora", the type locality on the Mozambican coast, combined with the Latin adjectival suffix -ensis ("originating from").Remarks
Specimens had been treated as an undescribed taxon for nearly two decades before the species was formally described from Mozambican material in 2017. The congeneric Aldisa fragaria, described in the same paper, also bears two dorsal depressions but differs in tubercle morphology and lacks the strongly serrated rhinophoral and branchial sheaths characteristic of A. zavorensis.References
