Chicomurex pseudosuperbus is a large Chicomurex ranging from Okinawa, Japan to Philippines to New Caledonia and Queensland, Australia. Majority of specimens have come from the central Philippines where it is common, outside Philippines it is uncommon to moderately rare.

It was named pseudosuperbus because it has been misidentified as C. superbus in the recent literature. It has been confused with C. lani Houart Moe Chen, 2014 [which was thought to be C. superbus (Sowerby III, 1889) until the rediscovery of its holotype.

C. superbus is now a senior synomym of C. problematicus (Lan, 1981)] but has a larger shell, more adressed suture, longer siphonal canal, more obvious axial nodes, and a more scabrous shell. It differs from the true C. superbus by having a narrower, higher spired shell with narrower secondary cords; also importantly the spiral cords are not as clearly overlaid with brown line as in C. superbus.

It is presumably a carnivorous gastropod like other Chicomurex and inhabits moderate depths around -60~200m. Typical shell length around 65mm, very large specimens may reach 85mm. – Adapted from Chong Chen’s post.
