Etymology: Paracheilinus: Greek, para = the side of + Greek, chaite = hair + Greek, odous = teeth (Ref. 45335).
More on authors: Randall & Lubbock.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 27 - 45 m (Ref. 9710), usually 27 - 45 m (Ref. 27115). Tropical; 25°N - 5°N
Western Pacific: Philippines, north to Taiwan and Iriomotejima, south to northern Bali and Flores (Ref. 37816). Recently recorded from Tonga (Ref. 53797). Replaced by Paracheilinus mccoskeri in the Indian Ocean (Ref. 37816).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 9;
Vertebrae: 25. In males, color is generally orange (yellow- or red-orange); lower fourth of head and body pale yellow; 2-4 dorsal soft rays prolonged (every other ray beginning with first). Males larger and more colorful than females; color of males intensify during courtship. Female specimens light red, pale white ventrally. Median predorsal scales 4-6 (Ref. 2139). Penultimate dorsal soft ray of males 1.8-2.2 in HL; two short dark stripes beneath pectoral fin (Ref. 41634).
Found on bases of steep outer reef slopes, above coral or rubble (Ref. 9710). Forms schools. Maximum depth reported from Ref. 27115.
