Etymology: Branchiostegus: Greek, brangchia = gills + Greek, stego = roof, to cover (Ref. 45335); saitoi: A new species of Branchiostegus was first caught off Batangas Laiya, Philippines in 2009, photographed and eaten. Two years passed before two more specimens were caught by J. Saito, an amateur angler from Japan in April, 2011. Without J. Saito’s considerable efforts and interest, this species would have remained unknown. The new species is herein named in his honor (Ref. 89848).

Morphology | Morphometrics
soft rays: 12;
Vertebrae: 24. This species is distinguished from its congeners by the following set of characters: great body depth (28-29% SL; vs. the usual 27% SL); longer head length 30-31% SL (vs. usual 28%),: head profile oblique, about 130 degree angle (vs. usual 95-130 degrees); head depth 26-27% SL (vs. usual 26% SL); eyes high on head, interorbital width 31-34% HL; small orbital diameter 24–25% HL, only B. sawakinensis and B. albus with small orbital diameters, 23-24% HL) long predorsal length 35% SL (vs. usual 30-32% SL, rarely 33-34% SL), deep body 28-29% SL (vs. usual 24-27%, rarely, only in B. japonicus and B. semifasciatus, 28-29% SL); wide body 14-15% SL (vs. usual 11-13% SL); number of first arch gill rakers low 18 + 1 rudimentary (vs. most other species 18-24, modally 19-22) (Ref. 89848).
This species inhabits burrows as do other tilefishes (Ref. 89848).
