背的软条 (总数) : 11 - 12; 臀鳍软条: 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).
鉴别: 这种有别于延伸从眼睛到尾鳍基底藉由的灰白的斑纹跟随组合特征的它的有一个的 Horsti 复合体 ( sensu Bohlke&罗宾 1968 世) 的同类: 深色的纵向斑纹宽的, 达到下腹部与臀鳍基底-鳍;(vs. 从不达到的腹部或臀鳍基底鳍) 胸鳍鳍条典型地 18(vs. 典型地 17 在 E. randalli 与 E. figaro 中与典型地 16 在 E. atronasum(Bohlke&罗宾) 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).
岛的周围发现在岩礁与石灰质-藻类浅堆上了。 和从巨大的体型食肉动物改变对体型小吃浮游生物的动物例如 Chromis multilineata(Guichenot) 的例如 加勒比真鲨〔Carcharhinus perezi〕 (Poey) 的客户在清洁活动中观察在白天期间 (与它生命期的大部份-周期) 。 (参考文献 52745)
