Diagnostic Features
|
- Test ovate in outline, hemispherical to subconical in profile with low ambitus.
- Apical system central, tetrabasal with four gonopores; genital plates subequal in size and all in contact. The posterior ocular plates small and widely separated to the rear of the posterior genital plates.
- Periproct longitudinal, ovate to tear-derop-shaped, inframarginal in postition.
- Ambulacra narrow adapically, petals undeveloped, pore-pairs small, simple, uniserial throughout, becoming a little offset in lines of three adorally. No buccal pores. Ambulacral plating simple above the ambitus, pyrinoid below the ambitus with one or both of the smaller elements excluded from the perradial suture.
- Interambulacra wide. Tuberculation of small uniform primaries with slightly sunken areoles scattered over plates with a dense unifrom granulation in between. No oral/aboral differentiation.
- Peristome subcentral, subcircular to strongly oblique, orientated with major axis running from Amb. V to Iamb. 2a; opening a little sunken.
- Lantern, lantern supports and spines all unknown.

| Classification and/or Status |
Irregularia; Echinoneoida, Conulidae.
Objective junior synonym of Adelopneustes Gauthier, 1889.

| Remarks |
Many of these species are distinguished on slight differences in overall shape and are unlikely to prove useful. The genus was synonymized with Adelopneustes by Smith & Jeffery (2000).
