This species is similar to Eviota albolineata in having similar counts or measurements. Color differences in live and preserved materials are distinct, however, with E. guttata having a dark spot on the ventral side of the head on the isthmus, about in line with the posterior portion of the maxilla and presence of a few scattered melanophores on the underside of the lower jaw near the tip, the intensity of the dark pigmentation varies, from a few melanophores to a very dark area (absent in E. albolineata) (Ref. 83982). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).

Description: Characterized further by longitudinal scale series 23-25; ctenoid scales, absence on head, nape and pectoral fin base; separated pelvic fins, thin membrane joins bases; 6-9 branches on fourth pelvic ray; depth of body 6.5-7.7 in SL (Ref. 90102).
