Genus Euchelipluma Topsent, 1909

Euchelipluma Topsent, 1909: 18 .

Desmatiderma Topsent, 1928b: 308 .

Diagnosis: Cladorhizidae pinnate or branching, with placochelae, smooth arcuate/ palmate isochelae and sigmancistras (from Hestetun et al. 2016b).

Type species: Euchelipluma pristina Topsent, 1909 (by original designation).

Remarks. Euchelipluma currently contains four species having placochelae similar to those of Guitarra, and therefore traditionally placed within the family Guitarridae . However, Hestetun et al. (2016a) recently proposed reallocating the genus to Cladorhizidae based on its general morphology, the presence of sigmancistras in addition to arcuate isochelae, and molecular data, indicating a close affinity to other carnivorous sponge genera, closest to but differentiated from Abyssocladia by also possessing placochelae. Current described species are E. arbuscular (Topsent, 1928c) E. congeri de Laubenfels, 1936, E. elongata Lehnert, Stone & Heimler, 2006, and E. pristina Topsent, 1909 (Table 17).
