Pachybrachis latithorax is a of case-bearing leaf beetle in the Chrysomelidae. It occurs in Central America and North America. The species belongs to a commonly known as 'scriptured leaf beetles' for their often intricate elytral patterns. Like other members of Pachybrachis, it is presumed to feed on foliage of various plants, though specific associations remain poorly documented.

Members of Pachybrachis are small, convex leaf beetles typically 3–6 mm in length, with rounded bodies and short . They are distinguished from similar by the combination of: a broad, rounded pronotum that often covers the from above; that are usually patterned with spots, lines, or mottled coloration; and the presence of a scutellar (a fine groove or line near the scutellum). P. latithorax specifically has been noted for its relatively broad (reflected in the epithet 'latithorax'). Separation from requires examination of genitalia and detailed comparison of elytral pattern and pronotal shape.
