Gellius tubuloramosus Dendy, 1924

( Fig. 3L )

Gellius tubuloramosus Dendy, 1924: 323 (no illustration).

Haliclona tubuloramosa ; Burton 1932: 266.

Sigmadocia tubuloramosus ; Bergquist & Warne 1980: 24, pl. 9a; Kelly et al. 2009: 44 (listed only).

This species was described by Dendy from North Cape, New Zealand,approximate coordinates 34.4167°S 173.0833°E, depth 128 m (wet holotype BMNH 1923.10.1.61). The genus Gellius Gray, 1867 is currently considered a subgenus of Haliclona Grant, 1841 and transfer of the present species to Haliclona (Gellius) created a junior secondary homonymy with syntype specimens described by Carter (1887: 70, pl. 6 fig. 1) from the Mergui archipelago as Isodictya simulans var. tubuloramosa . Isodictya simulans ( Johnston, 1842 as Halichondria ) is currently Haliclona (Haliclona) simulans , a species confined to European waters. Two syntypes are kept in the collection of the Natural History Museum, BMNH 1887.6.1.7 and 1887.6.1.14. Transferred to Haliclona , the combination became Haliclona tubuloramosa ( Carter, 1887) , which then became a senior secondary homonym of Gellius tubuloramosus Dendy, 1924 , currently Haliclona (Gellius) tubuloramosa . The two species differ a.o. by the absence of sigmas in Carter’s tubuloramosa . To remove the homonymy, I propose here Haliclona (Gellius) arthuri nom.nov. named after Arthur Dendy, for the New Zealand species.
