The green lacewing genus name Cryptochrysa Freitas Penny 2001 is identified as a junior homonym of Cryptochrysa Hampson 1926 (Lepidoptera: Noctuidae). Moreover, Titanochrysa Sosa Freitas 2012 is determined to be an available junior synonym of Cryptochrysa Freitas Penny. Thus, Titanochrysa becomes the substitute name for the preoccupied generic name. Here, we also provide (i) new information and images for Titanochrysa chloros (Freitas Penny) comb. nov., the only species ever included in the chrysopid genus Cryptochrysa, (ii) a clarified set of diagnostic features for the reconstituted genus Titanochrysa, and (iii) a key and images for identifying the six described Titanochrysa species.
