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)
