Etymology: Symphysanodon: Greek, syn, symphysis = grown together + Greek, physis = growth body form + Greek, odous = teeth; related to few teeth which are located over the area where the two jaws meet (Ref. 45335); rhax: Name rhax (berry or grape) is from the Greek and is an allusion to the similarity of this new species to S. berryi. The new name is a feminine noun in apposition to Symphysanodon..

簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 9; 背的軟條 (總數): 10; 臀棘 3; 臀鰭軟條: 7; 脊椎骨: 25. This species is separable from all other species of the genus, except S. berryi, by the following combination of characters: segmented rays in anal fin 7, tubed lateral-line scales 50, total gillrakers on first gill arch 35-38 (10 or 11 + 25-27), sum of lateral-line scales and gillrakers on individual specimens 85-88, depth of body 20.6-24.8% SL (4.0-4.9 times in SL), length of depressed anal fin 21.8-23.9 % SL, length of anal-fin base 12.6-14.8% SL, length of first anal-fin spine 3.0-4.8% SL, hypurals 1 & 2 autogenous, hypurals 3 & 4 represented by a single plate, and first caudal vertebra without parapophyses. It can be separated from the Atlantic species S. berryi by a number of morphometric characters. It also differs slightly from S. berryi in counts of pectoral-fin rays (17 or18, mean = 17.33, for S. rhax
vs. 16-18, mean = 16.99, for S. berryi).
除了 S. berryi 以外, 這種從所有的其他種的本屬是可分離的, 藉由跟隨組合特徵: 在臀鰭 7 ，管狀的側線鱗片 50 中的分段鰭條, 在第一鰓弓 35-38(10 或 11+25-27) 上的總鰓耙, 在個別的標本 85-88 ，身體 20.6-24.8% SL 的深度. ，扁平臀鰭 21.8-23.9% SL 的長度上的側線鱗片與鰓耙的總數, 臀鰭基底 12.6-14.8 的長度% SL, 第一個臀鰭的長度棘 3.0-4.8% SL, 尾下骨 1&2 自生的, 尾下骨 3&4 呈現出一個碟, 與第一個沒有椎體橫突的尾部的脊椎骨。 它能被一些型態特徵的特徵與大西洋種 S. berryi 分開。 它也在胸鰭鰭條的計數中些微地不同於 S. berryi(17 或 18, 平均的 =17.33, 對於 S. rhax
vs.16-18, 意謂 =16.99, 對於 S. berryi).
Depth of capture, 218 m, is available for only one collection.
