Colour

Fresh specimens with three to five red or pale brown bars on each caudal-fin lobe, the bars on the lower lobe interrupted or replaced by three or four dark-brown rounded or triangular spots at mid-lobe; dorsal, anal and pelvic fins with red pigment forming patches or stripes, barbels yellow, body and head red, with dark dots along lateral line and a saddle behind second dorsal fin; preserved fish with pale-brown head and body, sometimes with remains of pigmentation dorsally and on dorsal fins, bars on upper-caudal fin lobe mostly retained, spots on lower caudal-fin lobe always retained in both adults and subadults. 

Fisheries

Tken as bycatch in commercial prawn trawls.

Similar Species

Upeneus spottocaudalis differs from all other species in the genus in having the following combination of characteristics: 7 dorsal-fin spines, 12 or 13 pectoral-fin rays, 20–23 total gill rakers, head length 30–32% SL, and pectoral fins shorter than pelvic fins, the length of the latter 22–24% SL in adults and 24–26% SL in subadults; it differs from all other goatfishes in the presence of 3 or 4 conspicuous dark spots on lower-caudal fin lobe in fresh and preserved adult and subadult specimens.

Etymology

The specific name “spottocaudalis” refers to the conspicuous rounded or triangular dark spots or blotches on the lower caudal-fin lobe in both fresh and preserved specimens, an important diagnostic colour character of this species.
