Etymology: Kumba: Named for the Marine Biological Association of the United Kingdom, whose research vessel Sarsia dredged the type species.; calvifrons: From the Latin 'calvus' meaning bald, and 'frons' = forehead, in reference to the naked snout and forehead of the species..

(total): 2. Firm head not inflated. Sensory canals on head without enlarged pores. Dorsally scaleless posteriorly onto forehead as 2 projections lateral to median rostral ridge. Suborbital and nasal ridges distinct. Short barbel, about 9% of head length (HL); long upper jaw, 40% HL or more; orbit 27% HL, with snout equal to the orbit, 1.2 times longer than the interorbital. 1D II,11 (Ref. 11651).

Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00095 - 0.00504), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
