Styraconyx paulae Robotti 1971

Description

114. Styraconyx paulae Robotti, 1971

Styraconyx paulae spec. nov. (Robotti 1971)

Terra typica: Tyrrhenian Sea (Europe, Italy)

Tyrrhenian Sea:

38°48′N, 15°15′E; 2 m bsl: [FAO37] Type locality: Italy, Aeolian Islands, Stromboli Island, submerged ravine, from scleractinian coral (Coenocyathus dohrni Död.). Robotti (1971)

Record numbers (Sea/Ocean classification): Tyrrhenian Sea: 1; total: 1.

Record numbers (FAO classification): FAO37: 1; total: 1.

Remarks: This species belongs to the sargassi group and is very similar to S. sargassi. The original description was based on a single specimen, and it is known only from the type locality. However, Pollock (1983) suggested that some specimens attributed to B. tetronyx should be recognised as Styraconyx paulae. But, these B. tetronyx specimens were attributed by Renaud-Mornant (1967b) to S. sargassi, although later Pollock’s interpretation was confirmed by Kristensen & Higgins (1984a). In conclusion, this species is known from only one specimen, its diagnosis is uncertain, and the species is in need of redescription.
