DiagnosisDiagnosis: Phalotris bilineatus can be distinguished from all other congeners in the P. bilineatus group by a unique combination of the following characters: head dorsally black with rostral and first supralabials lighter; and ventrally almost white (vs. head entirely black in P. illustrator); nuchal collars absent (vs. present in other species of the group, with exception of P. illustrator and P. spegazzinii); belly with ventral scales white, with a half-moon shaped black dot in the anterior portion of each ventral scale; the dots enlarge toward posterior region of body, occupying almost all surface of ventral scales, being white only on the borders in contact with dorsal scale rows (vs. almost entirely black in P. illustrator, and P. spegazzinii); sides of the body with a narrow black stripe on 4–5th dorsal scale rows and 1–3rd dorsal scales rows white (vs. wider black lateral stripe 3–4 scales wide in P. illustrator, P. reticulatus and P. spegazzinii); cloacal shield with black ring present (vs. absent in P. multipunctatus); rostral scales projected backward, reaching or slightly separated from the prefrontal (vs. rostral well separated from the prefrontal in other species of the group). (Scrocchi et al. 2022).
