Original description: The genus Cryptocentrus was first described by Valenciennes in 1857 based on a specimen collected in the Red Sea (C. cyrptocentrus) Herre is credited (Debelius & Baensch, 1994) as describing Cryptocentrus cinctus in 1936, however a search of available sources finds Herre describing Smilogobius cinctus in 1936 in the Bull. Raffles Mus. v.12; from a specimen collected on a reef in the Singapore Harbor. Other references exist for description of Cryptocentrus species by Herre in 1927 (2), 1932, 1934, and 1935. No validation for S. cinctusis cited nor is any validation of C. cinctus is noted..

The Smithsonian collection lists three specimens collected: Taylor,1981 Halmahera Islands, Indonesia; Chapman, 1944 New Georgia, Soloman Islands; and Ferraris, 1980, Bolinao Lagoon,  Pangasinan, Philappines.

Word origin: The genus Cryptocentrus is from the Greek roots crypt, -o, meaning hidden or concealed; and centr, -i, -o, =um meaning a point or spur. The species cinctus appears to be from the Latin word cinct meaning girdled. The color morph mentioned (Banded prawn goby) may have been the type originally collected.
