Etymology: rapa: From the word rapum, meaning turnip or rape (in reference to its minute golden yellow spots on head, body and fins like in rape blossoms) (Ref. 75057).
Eponymy: Professor Cornelius Jan van der Horst (1889–1951) was a Dutch zoologist who moved to South Africa (1928) and became Head of the Zoology Department, Witwatersrand University, Johannesburg. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 11; Anal spines: 1; Anal soft rays: 11. This species differs from other congeners in having the following characters: 11 segmented rays on second dorsal fin; 33-35 longitudinal scale count; no predorsal scales; 11-12 transverse scale count from origin of second dorsal fin backward and downward to anal-fin base; naked pectoral-fin base; third spine of first dorsal fin longest, slightly elongate and filamentous; sensory-papillae row comprising four sensory papillae; a deep trough along posterior margin of eyes (Fig. 5B); first dorsal fin with numerous minute scattered yellow spots and no yellow submarginal lines; four faint brownish (tinged with yellow) mid-lateral blotches (rather than saddle-like bars) on body (Ref. 75057).
Occurs in coarse sandy bottom around rubble area, and found to be symbiotically associated with the alpheid shrimps (Ref. 75057).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00355 - 0.02566), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.2 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
