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. Jewett.

背棘 (总数) : 7; 背的软条 (总数) : 8 - 9; 臀棘: 1; 臀鳍软条: 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).
雄性与雌性都有的多皱纹的生殖乳突。 没有它孔; 邮局协议孔不存在或者非常缩小的。 4- 在腹的中联机的 6个大的斑点在后部地从臀鳍起源; 皮下的横带伴随着一些腹面-中线的斑点了。 第五个腹鳍鳍条小的，不分枝的, 大约第 4个鳍条的 1/10 长度.(通常钙化不足) 第 4个腹鳍鳍条延长的最前面分支, 至少 10个片段。 背棘在 D 1 不延长如丝状突起。 9- 17个胸鳍鳍条可能是分枝。 (参考文献 38034)
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).
发现在礁坪也只在浅滩 (<4.6 公尺) 中掩蔽的栖息地以在海湾 (没有围绕着珊瑚的涌浪，淤泥与泥) 中是正后方或从在船坞漂流物上弄脏群落。
