Cryptogemma is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids.^[1]

Distribution

These are deep-sea species with a wide geographic distribution.

Species

According to Zaccharias et al. (2020) this genus should only include:

Cryptogemma aethiopica (Thiele, 1925)
Cryptogemma periscelida (Dall, 1889)
Cryptogemma phymatias (Watson, 1886)
Cryptogemma powelli Zaharias, Kantor, Fedosov, Criscione, Hallan, Kano, Bardin & Puillandre, 2020
Cryptogemma praesignis (Smith, 1895)
Cryptogemma tessellata (Powell, 1964)
Cryptogemma timorensis (Tesch, 1915)
Cryptogemma unilineata (Powell, 1964).

The others should be excluded from this genus because the lack key characters such as the narrow fusiform shell and the well-marked peripheral anal sinus. They show closer resemblances to other conoidean families (such as Horaiclavidae) than to Turridae.^[2]

Species within the genus Cryptogemma include (according to WoRMS):

Cryptogemma aethiopica (Thiele, 1925)
Cryptogemma calypso Dall, 1919^[3] (taxon inquirendum)
Cryptogemma chrysothemis Dall, 1919^[4] (taxon inquirendum)

Cryptogemma periscelida (Dall, 1889)
Cryptogemma phymatias (Watson, 1886)^[9]
