Etymology: Pseudojuloides: Greek, pseudes = false + Greek, iouis = a fish without identification, perhaps some of genus Coris cited by Plinius + Greek, oides = similar to (Ref. 45335)severnsi: Named after Mike Severns who organized the collection and deposition of the type material from Alor, Indonesia.
Eponymy: R Michael ‘Mike’ Severns is the dive guide who collected the first specimens of both fish. He operates Mike Severns Diving in Maui, Hawaii. He is also very knowledgeable about the location of fossil deposits and birds. A bird is also named after him. (Ref. 128868), visit book page.

Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 11; Spine anali: 3; Raggi anali molli: 12. With a large blue-margined black patch covering the posteriodorsal region of the head and the dorsal anterior third of the body, an orange submarginal line along the length of the dorsal fin, and upper and lower rays of the caudal fin forming dark lobes that protrude beyond the medial caudal margin (Ref. 35870).

Biologia     Glossario (es. epibenthic)

Mainly in open ground areas covered with rubble; may also be found in areas with rock and coral patches (Ref. 35870). Found in small harems and feeds on material on the substratum (Ref. 35870). Minimum depth reported from Ref. 35870.

Estimates based on models

Preferred temperature (Ref. 123201): 24.8 - 28.8, mean 27.5 °C (based on 216 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00466 - 0.02049), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
