Features |
Vertebrae - preanal 43-48, precaudal 52-60, total vertebrae 181-189. Gill opening very small, its width 1.8–9.0% of head length; gill opening separated from pectoral fin base by a greater distance than its width; head length 1.4–1.7 times in trunk length, 35.2–40.9 %PAL; predorsal length 12.6–14.5 %PAL, trunk length 59.1–64.8 %PAL. Preanal lateral-line pores 39–47. MVF 9–46–185. |

Etymology |
The specific name parvibrachialis is from the Latin parvus (= little) and branchialis (= gills), in reference to the "very small gill opening, with the appearance of a large pore with a slightly elevated cutaneous rim.” |
