Body elongate with a rectangular cross-section. Head length 4.5-5.0 in SL. Eye diameter 3.1-3.3 in HL. Jaw teeth conspicuous and conical. Lower and upper jaw almost equal in length. Palatine teeth absent. Pectoral fins long (1.3-1.4 in SL) with* first two rays unbranched*, fin reaching to caudal fin base. Pelvic fins long (2.8-3.4 in SL), reaching well beyond anal fin origin, with pelvic origin nearer to anal fin than pectoral fin base. Dorsal fin low (longest ray more than 10 times in SL). Origin of anal fin slightly ahead of, equal with, or slightly behind (under 1st-2nd ray) dorsal fin. Caudal fin forked with the lower lobe longer than upper. Lateral line low on side. Pectoral branch of lateral line absent. Juveniles with enlarged pelvic fins and no chin barbel(s).

Other Notes

There are two populations of black-winged Hirundichthys in the western Atlantic: one in the northern Atlantic and one in the southwestern Atlantic. The northern population was given the name Hirundichthys rondeletii volador and the southern population given the name H. r. rufipinnis (Parin & Belyanina, 2002). These have been elevated to species in the recent (2016) FAO guides.
