182F87A0FFBD717AFF2AFC2658F1F83A.taxon	discussion	Remarks: Menegola et al. (2012) described Strongylacidon oxychaetum with a spicular set composed of strongyles and arcuate isochelae, in addition to a skeleton organized as bouquets of strongyles. At the time, the authors mentioned that the species had a plumoreticulate skeleton. However, when analyzing the images available in Menegola et al. (2012) and in the material analyzed here, we found that the skeleton is actually reticulate. This characteristic suggests that the species is better allocated to Lissodendoryx instead. Furthermore, because it contains only a single type of megascleres, we assign this species to the subgenus L. (Anomodoryx), as L. (Anomodoryx) oxychaetum (Menegola, Santos, Moraes & Muricy, 2012) comb. nov..	en	Barros, Thales, Cavalcanti, Thaynã, Hajdu, Eduardo, Pinheiro, Ulisses (2023): Lissodendoryx Topsent, 1892 (Poecilosclerida: Coelosphaeridae) from Brazil: a new species and transfer of Strongylacidon oxychaetum Menegola, Santos, Moraes & Muricy, 2012 to the genus Lissodendoryx.

182F87A0FFBB717CFF2AF8AA588DFC7A.taxon	discussion	Remarks: The analyzed specimen was assigned as a member of the subgenus L. (Anomodoryx) because it has only tylotes as megasclere. From this, it was identified as L. (Anomodoryx) vulcanus due to its skeletal architecture and spicular set being similar to that exhibited by the holotype (Cavalcanti et al. 2014). Because the present materials comprise only fragments, it was not possible to observe the morphological characteristics described for the holotype from Rio Grande do Norte State. With this record, we expand the bathymetric occurrence to shallower waters (27 m depth), previously only known from 108 m depth (Cavalcanti et al. 2014).	en	Barros, Thales, Cavalcanti, Thaynã, Hajdu, Eduardo, Pinheiro, Ulisses (2023): Lissodendoryx Topsent, 1892 (Poecilosclerida: Coelosphaeridae) from Brazil: a new species and transfer of Strongylacidon oxychaetum Menegola, Santos, Moraes & Muricy, 2012 to the genus Lissodendoryx.

182F87A0FFBA717EFF2AFCF358B7FDE2.taxon	discussion	Remarks: The analyzed specimen was identified as belonging to the subgenus L. (Lissodendoryx) because it presents styles as choanosomal megascleres and tylotes as ectosomal megascleres. It has a spicular set similar to that described by R ̧ tzler et al. (2007) for the species L. (Lissodendoryx) carolinensis, so it was identified as the aforementioned species. The Caribbean specimens, as described by R ̧ tzler et al. (2007), show external morphology and coloration different from the Brazilian specimen studied here, where it was possible to observe a yellowish-pink coloration and arborescent shape, with the absence of oscules, while in the Caribbean specimens the coloration can vary from blue, green and greenish-tan, to dirty orange and bright orange. Its shape is tubular, similar to a chimney, with a single oscule at the top. In addition, there are also differences in the size of isochelae I and II and sigmas I and II, with isochelae I and II and sigmas I being larger in the Brazilian specimen. Sigmas II are larger in the specimens from the Caribbean (see Table 1). These differences are considered intraspecific variations in the wide geographical distribution of the species. This is the first record of the species from Brazil.	en	Barros, Thales, Cavalcanti, Thaynã, Hajdu, Eduardo, Pinheiro, Ulisses (2023): Lissodendoryx Topsent, 1892 (Poecilosclerida: Coelosphaeridae) from Brazil: a new species and transfer of Strongylacidon oxychaetum Menegola, Santos, Moraes & Muricy, 2012 to the genus Lissodendoryx.

Skeleton (Fig 5 D): Ectosomal skeleton formed by brushes of tylotes (Fig 5 E) inserted in distinct subdermal spaces. Tylotes are also found in the choanossomal and subectosomal region traversing the surface. Choanosomal skeleton forming a pauci to unispicular isotropic reticulation of smooth oxeas and tylotes (Fig 5 F). Abundant spongin and debris present in the choanosome. Microscleres are found spread throughout the ectosome and choanosome. Spicules (Fig 5 G – K). Oxeas (161 – 186.4 – 206 / 3.2 µm): thin, smooth, slightly curved, needle-like tips (Fig 5 G). Tylotes (203 – 244.6 – 264 / 3.2 µm): thin, smooth, straight, rounded tyles (Fig 5 H). Arcuate isochelae (23 – 24.0 – 26 µm): slightly curved axis, short and curved alae (Fig 5 K).	en	Barros, Thales, Cavalcanti, Thaynã, Hajdu, Eduardo, Pinheiro, Ulisses (2023): Lissodendoryx Topsent, 1892 (Poecilosclerida: Coelosphaeridae) from Brazil: a new species and transfer of Strongylacidon oxychaetum Menegola, Santos, Moraes & Muricy, 2012 to the genus Lissodendoryx.

182F87A0FFB87170FF2AFB2C5A58FE72.taxon	discussion	Remarks: The specimen was identified as belonging to the subgenus L. (Waldoschmittia) because it contains oxeas as choanosomal megascleres. Lissodendoryx (W.) almeidai sp. nov. differs from the other species of the subgenus by its spicular set and spicular dimensions. Lissodendoryx (W.) hawaiiana has sigmas as microscleres and larger oxeas than those of the new species; L. (W.) schmidti has sigmas and two categories of arcuate isochelae; finally, L. (W.) mediterranea, the species approaching the new species the most, is distinguished by having acanthoxeas as choanosomal megascleres. This is the first record of the subgenus L. (Waldoschmittia) from the Atlantic Ocean (Table 2).	en	Barros, Thales, Cavalcanti, Thaynã, Hajdu, Eduardo, Pinheiro, Ulisses (2023): Lissodendoryx Topsent, 1892 (Poecilosclerida: Coelosphaeridae) from Brazil: a new species and transfer of Strongylacidon oxychaetum Menegola, Santos, Moraes & Muricy, 2012 to the genus Lissodendoryx.
