- <p><b>Support of <i>Leucophloeus lewisi</i> Van Soest and Stentoft, 1988, classification as <i>Axinyssa</i></b></p><p><i>Leucophloeus</i> Carter was erected (by monotypy) for the species <i>Leucophloeus massalis</i> Carter, 1883. Subsequently, Van Soest and Stentoft (1988) described anotherspecies from the Caribbean, <i>Leucophloeus lewisi</i> Van Soest & Stentoft, 1988, but noted that the generic allocation of the species remained uncertain due to major differences in the choanosomal architectures compared to the type species, <i>L. massalis</i>. In the course of Van Soest <i>et al’s</i> revision of Halichondriidae (1990), <i>Leucophloeus</i> was synonymized with <i>Ciocalypta</i> Bowerbank, and later, <i>L. lewisi</i> with <i>Axinyssa ambrosia</i> (de Laubenfels, 1936) (Diaz <i>et al.</i> 1993; Van Soest <i>et al.</i> 1990), and subsequently with <i>Axinyssa yumae</i> (Pulitzer-Finali, 1986) (see Zea <i>et al.</i> 2013).</p><p>We sequenced the 28S-C region of the holotype of <i>L. lewisi</i> (ZMA Por.5401, INV-POR 0514, collected in 1964, sequence length 486 bp). The resulting phylogenetic reconstruction supports the classification outside <i>Ciocalypta</i> and to <i>Axinyssa</i> (Fig. 3; see Gutekunst <i>et al.</i> 2018 for a detailed discussion on the problematic classification of both genera among Suberitida), and further distinguishes this species from <i>A. ambrosia.</i> Unfortunately, sequence data for <i>A. yumae</i> is currently not available to further resolve synonymisation of both taxa. That said, the species <i>Leucophloeus lewisi</i> is transferred to the genus <i>Axinyssa</i> and should be referred to as <i>Axinyssa lewisi</i> (Van Soest and Stentoft, 1988)</p>
