Etymology: Cathorops: Greek, kathorao = to observe, to watch + Greek, ops = appearance (Ref. 45335); manglarensis: The specific epithet manglarensis makes reference to type-locality and life habit of the species, common in mangrove regions and estuaries from the Colombian Pacific (Ref. 58753).

Cathorops manglarensis is distinguished from all congeners through the following combination of characters: 13-16 gill rakers on first arch; 24-27 anal fin rays; dorsal fin spine shorter than pectoral fin spine; posterior margin of pectoral fin spine with shorter serrations. This species can be further distinguished from each of the other species from the Pacific coast of Central and South America by additional characters. Cathorops manglarensis is distinguished from C. dasycephalus in lacking vomerine tooth plates (vs. vomerine tooth plates present) and an osseous bridge formed by the lateral ethmoid and frontal without granulation (vs. granulated along its entire extension). It differs from C. fuerthii by having a median groove of neurocranium deep and large, with lateral margins regular and progressively narrower posteriorly (vs. median groove narrow and shallow, with irregular margins along its entire extension), anterior nostrils closer to each other (3.6-4.8 vs. 4.9-6.0% SL), longer external mental barbel (19.7-24.4 vs. 15.9–19.7% SL), longer internal mental barbel (12.5–17.9 vs. 10.3–12.9% SL), and longer
anal fin base (21.0–24.5 vs. 17.8–19.4% SL). It differs from C. hypophthalmus in possessing a shorter distance between anterior nostrils (3.6–4.8 vs. 6.9–7.1% SL) and between posterior nostrils (5.2–7.1 vs. 8.2–8.5% SL), larger orbital diameter (3.7–4.8 vs. 3.0–3.5% SL), narrower mouth (8.8–10.5 vs. 13.1–13.2% SL) and with shorter external mental barbel (19.7–24.4 vs. 34.5–38.1% SL), internal mental barbel (12.5–17.9 vs.
26.1–31.2% SL), and dorsal fin spine (16.9–19.2 vs. 25.0–25.2% SL). Cathorops manglarensis differs from C. multiradiatus in possessing a longer maxillary barbel (28.4–38.2 vs. 22.9–27.7% SL) and pectoral fin spine (18.5–22.5 vs. 16.9–18.7% SL), and longer and wider accessory tooth plates with large and numerous molariform teeth (vs. shorter and narrow accessory tooth plates with small and few molariform teeth). Cathorops manglarensis differs from C. tuyra in possessing a longer internal mental barbel (12.5–17.9 vs. 8.20–12.4% SL) and pectoral fin spine (18.5–22.5 vs. 16.9–18.7% SL), shorter nuchal plate (5.0–6.8 vs. 6.8–7.5% SL), longer anal fin base (21.0–24.5 vs. 13.9–18.3% SL), deeper caudal peduncle (7.8–8.9 vs. 5.8–7.8% SL), and accessory tooth plates and dentary with moderately large molariform teeth (vs. accessory
tooth plates and dentary with very large molariform teeth) (Ref. 58753).
Cathorops manglarensis 在組合特徵之後被與所有的同類經過區分: 在第一鰓弓上的 13-16個鰓耙; 24-27個臀鰭棘條; 背鰭棘短於胸鰭棘; 胸鰭棘的後緣有短的鋸齒。 這種可能是與進一步區分的附加特徵的中美洲與南美洲的每一個另一個種從太平洋海岸。 Cathorops manglarensis 在由側面的中篩骨與沒有粗粒的額骨形成的缺乏犛骨齒板 (vs. 犛骨齒板存在的) 與一座骨的橋中被與 C. dasycephalus 區分。 (vs. 顆粒狀的沿著它的整個延長) 它藉由有一個有別於 C. fuerthii 腦顱的中央凹槽深的而且大的, 與側面的邊緣規則與漸進比較狹窄的在後部地 (vs. 中央的凹槽狹窄的與淺灘, 有不規則的，邊緣沿著它的整個延長), 前鼻孔更靠近彼此 (3.6-4.8 vs.4.9-6.0% SL) ，更長的外部神經觸鬚 (19.7-24.4 vs.15.9-19.7% SL) ，比較長的內在神經觸鬚 (12.5-17.9 vs.10.3-12.9% SL), 與更長的
臀鰭基底.(21.0-24.5 vs.17.8-19.4% SL) 它有別於 C. hypophthalmus 在持有方面一比較短的前鼻孔 (3.6-4.8 vs.6.9-7.1% SL) 之間的距離與在後鼻孔 (5.2-7.1 vs.8.2-8.5% SL) ，比較大的眼窩直徑 (3.7-4.8 vs.3.0-3.5% SL) 之間, 較狹窄的嘴 (8.8-10.5 vs.13.1-13.2% SL) 而且有短的外部神經觸鬚 (19.7-24.4 vs.34.5-38.1% SL) ，內在的神經觸鬚 (12.5-17.9 vs.
26.1-31.2% SL), 與背鰭棘.(16.9-19.2 vs.25.0-25.2% SL) Cathorops manglarensis 在持有一個更長的顎觸鬚 (28.4-38.2 vs.22.9-27.7% SL) 與胸鰭棘 (18.5-22.5 vs.16.9-18.7% SL) 方面有別於 C. multiradiatus ，而且更長與更寬附屬的齒板有大的與很多的臼齒型齒.(vs. 比較短而狹窄的附屬齒板有小的與少數臼齒型齒) Cathorops manglarensis 有別於 C. tuyra 在持有一個更長的內在神經觸鬚 (12.5-17.9 vs.8.20-12.4% SL) 與胸鰭棘 (18.5-22.5 vs.16.9-18.7% SL), 比較短的頸背碟 (5.0-6.8 vs.6.8-7.5% SL) ，較長的臀鰭基底 (21.0-24.5 vs.13.9-18.3% SL) ，較深的尾柄 (7.8-8.9 vs.5.8-7.8% SL) 與附屬的齒板方面與齒骨有普通大的臼齒型齒 (vs. 配件
齒板與齒骨具有非常大的臼齒型齒).(參考文獻 58753)
