Etymology: Pictichromis: Name from Latin pictus meaning painted or colored, and Greek Chromis, a genus of pomacentrid, used as the stem for other fish genera; alludes to the bright live colorations of the included species (Ref. 81967); caitlinae: Named for Ms. Caitlin Elizabeth Samuel.
Eponymy: Ms. Caitlin Elizabeth Samuel (d: 1993) is the daughter of a supporter of a conservation initiative. The etymology says: “The new species is named caitlinae for Ms. Caitlin Elizabeth Samuel, a young Canadian leader, on the occasion of her sixteenth [...] (Ref. 128868), visit book page.

Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 3; Raios dorsais (total) : 22; Espinhos anais: 3; Raios anais : 11 - 12. This species is distinguished from its congeners by having a bright yellow-orange snout/forehead, and a strongly contrasted magenta coloration over the remainder of the head and body. The species Pictichromis aurifrons has a similar yellow colour pattern, but with the remainder of the head and body being light purple to bluish grey, rather than magenta, and the gradation between the two contrasting colours is relatively gradual rather than abrupt (Ref. 74963).
Common in the inner portion of the bay, observed at 16 of 27 inner bay sites during the 2006 survey. This species is replaced by P. porphyrea (Lubbock & Goldman, 1974) in the outer portion of the bay (e.g. vicinity of Biak) . It occurs on relatively silty, turbid reefs at depths
between about 10 and 55 m, generally around rocky outcrops (Ref. 74963).
