Etymology: Elacatinus: Greek, elakatines = fusiform fishes preserved in salt (Ref. 45335); pridisi: Named for the Brazilian Navy First District (Primeiro Distrito Naval, Marinha do Brasil - "PRIDIS").
Eponymy: Not an eponym but in honour of the Brazilian Navy First District (Primeiro Distrito Naval, Marinha do Brasil, or ‘PRIDIS’), for the “…impeccable logistic support” provided during the authors’ field trips to Trindade Island, off Brazil, the type locality. (Ref. 128868), visit book page.

背的軟條 (總數) : 11 - 12; 臀鰭軟條: 11. Diagnosis: This species differs from its congeners of the Horsti complex (sensu Böhlke & Robins 1968) that have a pale stripe extending from the eye to the caudal-fin base by the following combination of characters: dark longitudinal stripe wide, reaching lower abdomen and base of anal-fin (vs. never reaching abdomen or base of anal fin); pectoral-fin rays typically 18 (vs. typically 17 in E. randalli and E. figaro and typically 16 in E. atronasum (Böhlke & Robins); anal-fin rays typically 11 (vs. typically 10 in E. figaro); oval spot present on snout (vs. no spot in E. atronasum and E. horsti (Böhlke & Robins), a "V"-shaped spot in E. prochilos (Böhlke & Robins), and a medial bar in E. xanthiprora (Böhlke & Robins), E. louisae (Böhlke & Robins) and E. lori Colin) (Ref. 52745).
Body shape (shape guide): elongated.
鑑別: 這種有別於延伸從眼睛到尾鰭基底藉由的灰白的斑紋跟隨組合特徵的它的有一個的 Horsti 複合體 ( sensu Bohlke&羅賓 1968 世) 的同類: 深色的縱向斑紋寬的, 達到下腹部與臀鰭基底-鰭;(vs. 從不達到的腹部或臀鰭基底鰭) 胸鰭鰭條典型地 18(vs. 典型地 17 在 E. randalli 與 E. figaro 中與典型地 16 在 E. atronasum(Bohlke&羅賓) 中; 臀鰭棘條典型地 11;(vs. 典型地 10 在 E. figaro 中) 橢圓形斑點位於吻 (vs. 沒有斑點在 E. atronasum 中與 E. horsti(Bohlke&羅賓)," V"-形狀的斑點在 E. prochilos(Bohlke&羅賓), 與一條中間的橫帶在 E. xanthiprora(Bohlke&羅賓),E. louisae(Bohlke&羅賓) 與 E. lori 柯林) 之上。 (參考文獻 52745)
描述: 身體裸露的, 延長。 在顎上的嘴接近端位又沒有犬齒。 沒有瘦長的前面棘的背鰭。 尾鰭圓的,而且腹鰭杯子完成。 背鰭鰭條 VII-11-12.(典型地 12) 臀鰭棘條 11. 胸鰭鰭條 17-18(典型地 18).(參考文獻 52745)
Found over rocky reefs and calcareous-algae banks around the island. Observed in cleaning activities during the day (and most of its life-cycle) with clients varying from large-sized carnivores such as Carcharhinus perezi (Poey) to small-sized planktivores such as Chromis multilineata (Guichenot) (Ref. 52745).
島的周圍發現在岩礁與石灰質-藻類淺堆上了。 和從巨大的體型食肉動物改變對體型小吃浮游生物的動物例如 Chromis multilineata(Guichenot) 的例如 加勒比真鯊〔Carcharhinus perezi〕 (Poey) 的客戶在清潔活動中觀察在白天期間 (與它生命期的大部份-周期) 。 (參考文獻 52745)
