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).

Γεννητική Ωρίμανση: Lm ? range ? - ? cm
Max length : 6.5 cm SL αρσενικό/απροσδιόριστο; (Ref. 48635)
Ραχιαίες άκανθες (συνολικά) : 3; Μαλακές ραχιαίες ακτίνες (συνολικά) : 22; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 10 - 12. This species is distinguished from its congeners by having a bright yellow snout/ forehead that grades into a light purple to bluish-grey coloration over the remainder of the head and body (Ref. 74963).
Body shape (shape guide): elongated; Cross section: compressed.
Found in sheltered habitats with rich coral growth to about 30 m depth (Ref. 48635). Observed in western New Guinea in habitats of silty dead coral reef, near the base of steep slopes 13-29 m depths; these reefs are characterised by numerous small caverns/overhangs and fish were usually seen adjacent to vertical surfaces. They appear to occupy territories or home ranges of about 2 sq. m and are often encountered solitarily, sometimes in loosely associated pairs (Ref. 74963).
