Neopodospongia carlinae (Boury-Esnault & van Beveren, 1982) 

During the process of establishing L. (Uniannulata) subgen. nov., Latrunculia carlinae Boury-Esnault & van Beveren, 1982  was re-examined because the microscleres appeared to be reminiscent of those in L. (U.) oparinae  subgen. nov., and the New Zealand fossil species L. (U.) paeonia  subgen. et sp. nov., in particular. The species was first described as a species of Latrunculia  by Boury-Esnault & Bevern (1982) despite the authors noting that the specimen had many non-latrunculid characters, and that the thistle-shaped ‘anisodiscorhabds’ were quite different from any other Latrunculia  microscleres described thus far ( Fig. 13View FIGURE 13 A). In 2006, the species was transferred to Sigmosceptrella  in the poecilosclerid family Podospongiidae  , by Samaai et al. (2006), but they ceded that it was perhaps still not quite the right place. By 2011, Sim-Smith & Kelly (2011) had described a range of new genera within Podospongiidae  , to which the species carlinae  seems to have greater affinity. After careful reexamination of the holotype ( Fig. 15View FIGURE 15) we now consider L. carlinae  to be better placed in podospongid genus Neopodospongia Sim-Smith & Kelly, 2011  , established for thin encrusting species with very similar characteristics. In particular, the aciculospinorhabd microscleres are in two size categories and protorhabd appears to be sigmoid, as in all Podospongiidae ( Sim-Smith & Kelly 2011)  .

Latrunculia carlinae  has microscleres with ragged apical spines ( Fig. 15View FIGURE 15 C –G) and are in two distinct morphological and size categories ( Fig. 15View FIGURE 15 C –E); the smaller microsclere is narrower, about 10 µm shorter, with a smaller apex. Although we did not find any specifically sigmoid protorhabds, we observed many protorhabds with the uneven lateral development ( Fig. 15View FIGURE 15 H) associated with the fusion of recurved sigmoid spines, as illustrated in Sim-Smith & Kelly (2011: Fig. 4View FIGURE 4 E, R). Neopodospongia carlinae  from subantarctic waters is the sixth in this widely-spread genus, which has three species in New Zealand, one species in the Chilean fiords, and one species in the North Atlantic ( Table 9).
