/ˌkrɪptəˈmoʊˌnæd/

Origin: Formed within English, by compounding; modelled on a Latin lexical item. Etymons: crypto- comb. form, monad n.

Etymology: < crypto- comb. form + monad n. In early use after scientific Latin Cryptomonadina, former family name (C. G. Ehrenberg 1832); in later use after Cryptomonadida, former order name; both < Cryptomonas, genus name (C. G. Ehrenberg 1832, in Abhandl. der math. u. physik. Klassen der Königl. Preussischen Akad. der Wissensch. 1831 56).

Biology.

Any of a group of flattened elliptical flagellates, formerly regarded as protozoans by zoologists or as green algae by botanists, and typically characterized by chloroplasts and two flagella.Now often treated as the protist phylum Cryptomonada (or Cryptophyta).
