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.;  raja: Named in reference to the type locality, Raja Ampat Islands (Ref. 44113).

Pectoral fin rays simple; spinous dorsal fin elongate or filamentous in both sexes, first to third (rarely fourth) longest; fifth pelvic fin ray well developed, five-tenths to nine-tenths length of fourth ray; cephalic sensory pore system lacking IT and PITO pores, and AITO pore single (except double in smallest paratype) and very large; posterior rays of second dorsal and anal fins elongate, forming a lanceolate shape; membranes of dorsal and anal fins slightly dusky; lower portion of caudal peduncle dusky and pair of vertically elongate black spots at upper and lower caudal fin base, their upper and lower edges often joined or nearly joined at middle of caudal peduncle, especially in mature adults (Ref. 44113).
胸鳍鳍条单一的; 刺状的背鳍细长或丝状的雄性与雌性都有, 第一个到第三 (很少地第四的) 长的; 第五个腹鳍鳍条发展良好的, 第四个鳍条的五-第十到九-第十长度; 头部的感觉小孔系统缺乏它与 PITO 孔 , 与 AITO 孔单一 (在小的副方式的除了加倍以外) 与非常大的; 第二背鳍与臀鳍的在后部鳍条延长,形成一个矛尖形的形状; 背鳍与臀鳍的薄膜些微暗色; 尾柄的低部分在上、下尾鳍基底的暗色与成对的细长垂直的黑色斑点, 他们的上、下边缘时常结合或者几乎在尾柄的中央结合, 尤其在成熟的成鱼 (. 参考文献 44113)
