Abstract
Hyalonematidae Gray (Hexactinellida, Amphidiscophora) contains five genera: Hyalonema; Charalonema; Composocalyx; Lophophysema and Platella. The genus Hyalonema is subdivided into 12 subgenera: H. (Hyalonema); H. (Corynonema); H. (Coscinonema); H. (Cyliconema); H. (Paradisconema); H. (Phialonemiella); H. (Prionema); H. (Pteronema); H. (Thamnonemiella); H. (Leptonema); H. (Onconema); H. (Oonema). The validity of genera Chalaronema and Composocalyx and some subgenera of Hyalonema: Paradisconema,Prionema and some others is questionable. Two new names Phialonemiella and Thamnonemiella are suggested to replace the former preoccupied names [Phialonema] and [Thamnonema]. The family is well distinguished among other Amphidiscophora by prevailing of diactines among choanosomal megascleres and presence of anchorate basalia with four and more teeth or discoidal basalia with serrated discs.
