From the Papua/ Solomon Acutotyphlops it can be separated by the presence of (1) a single ocular and preocular shield (vs. fragmentation into 6–10 shields), (2) three infralabials (vs. 5–7 shields), (3) fourth supralabial as tall as long (vs. at least twice as long as tall), (4) uniformly light dorsum and venter with irregular dark dorsal spots (vs. dark dorsum and light venter separated by a sharp demarcation), and absence of (5) retrocloacal sacs, and (6) a solid, awned hemipenis with helical coils in tail when retracted.|
