More Info

Distribution	Known only from the west side of Linnet Reef, Great Barrier Reef, Queensland. The species was collected from the gorgonian Ellisella quadrilineata at depths of 6-15 m.
Features	Dorsal fin VI + I, 8; Anal fin I, 8; Pectoral fin 16, some middle rays branched; Segmented caudal rays 9+8=17 (15 in two subadult paratypes); Branched caudal rays 11; Longitudinal scale series 39-50; Transverse scale rows 8-11.
Similar Species	Closely related to Bryaninops nexus Larson and B. erythrops (Jordan and Seale), with which it shares the absence of anterior and posterior nostrils. It differs from these two species in lacking ctenoid scales below the second dorsal fin, above the anal fin, and on the ventral side of the caudal peduncle. The species is also similar to B. loki, differing in having a higher pectoral-fin ray count, a deeper body (average 14% SL in B. loki, vs to 10% in B. tectus), the presence of nostrils, a longer gill opening (usually reaching orbit in B. loki, vs to below posterior half of preopercle in B. tectus), and scales dorsally on body reaching below origin of first dorsal fin in B. loki, compared to below to posterior end of the second dorsal fin in B. tectus. (Suzuki & Randall 2014)
Etymology	The specific name tectus is Latin meaning 'secret', 'hidden', or 'disguised', in reference to its being misidentified as another species.
