Cephrenes acalle, commonly known as the plain palm dart,[2] is a butterfly belonging to the family Hesperiidae.

[3] An examination of the type specimen showed that it was identical to Cephrenes chrysozona lompa Evans 1934 based on genitalia.

This has led to Cephrenes chrysozona being treated as a synonym.

The species breeds on palms including coconut, Calamus, Elaeis, Roystonea and Prychosperma.

[4][5] There are seven subspecies within the distribution range that extends from India through Indo-China into the Philippines.
