  Type species:

   Homophymia lamellosa Vacelet & Vasseur, 1971 by monotypy.

Introduction

Pisera & Lévi (2002) note that this genus was originally classified with some uncertainty within the Corallistidae, based on its monaxial desmas (Corallistidae, as here understood, has dichotriaenes as their ectosomal spicules, never pseudophyllotriaenes). The allocation of this genus into Neopeltidae was based on its monaxial desmas and ectosomal pseudophyllotriaenes (see also Kelly, 2000).

Distribution

IBRA and IMCRA regions

IMCRA

Norfolk Island Province (21)

Diagnosis

Thickly lamellar (consisting of several cylindrical individuals) or thickly globular with long stalk supplied with axial cavity. Desmas are pseudotetraclones (monocrepid), ectosomal megascleres are smooth pseudophyllotriaenes (monocrepid, crepis in the rhabd); microscleres consist of a single type of amphiaster.
