IngliżThis species can be distinguished from Potamorrhaphis eigenmanni and P. guianensis by having the posterior third of the labial membrane highly expanded laterally, reaching to or passing the level of the ventral margin of the maxilla when folded ventrally (vs. narrow, not reaching the level of the ventral margin of the maxilla when folded ventrally); from P. eigenmanni by having 3 rows of accessory teeth on the lower jaw (vs. 2 rows), and 115-128 scales on the lateral line (vs. 97-119); from P. guianensis by having the contralateral branchiostegal membranes overlapping in the midventral line (vs. branchiostegal membranes not overlapping ventrally), 3 rows of accessory teeth on the lower jaw (vs. 4 rows), and dentary with coronoid process salient (vs. coronoid process not salient); from P. petersi by the coloration of the labial membrane with melanophores only in the inner margin (vs. melanophores uniformly distributed), 29-34 dorsal-fin rays (vs. 35-43), 25-29 anal-fin rays (vs. 30-39), deeper caudal peduncle (2.1-2.7 vs. 1.1-1.6% BL), longer predorsal length (62.9-67.6 vs. 59.5-62.8% BL), longer pectoral-pelvic distance (38.5-42.6 vs. 36.0-38.1% BL), and longer head length (17.6-18.9 versus 15.8-17.9% BL) (Ref. 92518).

MaltiDin l-ispeċi jistgħu jiġu distinti minn Potamorrhaphis eigenmanni u P. guianensis minn wara li t-tielet posterjuri ta ' l-labial tal-membrana ħafna aktar fil-fond lateralment, li jintlaħaq għal jew li jgħaddi l-livell tal-marġini bridges ta ' l-maxilla meta mitwija ventrally (vs. dejjaq, ma jintlaħaq il-livell tal-marġini bridges ta ' l-maxilla meta mitwija ventrally); minn P. eigenmanni minn wara li 3 fillieri ta ' snien aċċessorju fuq l-xedaq t'isfel (vs. fillieri 2), u l-iskali 115-128 fuq il-linja laterali (vs. 97-119); minn P. guianensis minn wara li l-membrani contralateral branchiostegal overlapping fil-linja tal-midventral (vs. branchiostegal membrani overlapping ma ventrally), ir-ringieli 3 ta ' l-aċċessorju snien fil-xedaq t'isfel (vs. 4 ringieli), u dentary mal-coronoid proċess saljenti (vs. coronoid proċess ma saljenti); mill- P. petersi mill-kolorazzjoni ta ' l-labial tal-membrana ma melanophores biss fil-ġewwa marġini (vs. melanophores distribwiti b'mod uniformi), 29-34 dorsali denbu raġġi (vs. 35-43), 25-29 anal denbu raġġi (vs. 30-39), aktar profond kawdjali ma (2.1-2.7 vs. 1.1-1.6% BL), aktar predorsal tul (62.9-67.6 vs. BL 59.5-62.8%), distanza itwal mhux-pelviku (38.5-42.6 vs. BL 36.0-38.1%), u l-itwal tul ewlieni (17.6-18.9 versus BL 15.8-17.9%) (Ref. 92518).
