Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.;  susanae: Named for Susan J.

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 7; 背的軟條 (總數): 8-9; 臀棘 1; 臀鰭軟條: 6 - 8. This species is distinguished by the following characters: rugose genital papillae in both sexes. No IT pores; POP pores absent or greatly reduced. 4 - 6 large spots on ventral midline posteriorly from anal fin origin; subcutaneous bars associated with some ventral-midline spots. Fifth pelvic fin ray small, unbranched, about 1/10 length of 4th ray (usually poorly ossified). Anterior-most branch of 4th pelvic ray elongate, at least 10 segments. Dorsal spines in D1 not prolonged as filaments. 9 - 17 pectoral fin rays may be branched (Ref. 38034).
雄性與雌性都有的多皺紋的生殖乳突。 沒有它孔; 郵局協議孔不存在或者非常縮小的。 4- 在腹的中線上的 6個大的斑點在後部地從臀鰭起源; 皮下的橫帶伴隨著一些腹面-中線的斑點了。 第五個腹鰭鰭條小的﹐不分枝的, 大約第 4個鰭條的 1/10 長度.(通常鈣化不足) 第 4個腹鰭鰭條延長的最前面分支, 至少 10個片段。 背棘在 D 1 不延長如絲狀突起。 9- 17個胸鰭鰭條可能是分枝。 (參考文獻 38034)

生物學特性     字彙 (例如 epibenthic)

Found resting on the substrate in shallow (<4.6 m) sheltered habitats, either at patch reefs well back in the bay (no surge, silt, and mud surrounding the coral) or from fouling communities on dock floats (Ref. 38034, 116739).

發現在礁坪也只在淺灘 (<4.6 公尺) 中掩蔽的棲息地以在海灣 (沒有圍繞著珊瑚的湧浪,淤泥與泥) 中是正後方或從在船塢漂流物上弄髒群落。
