Worldwide, the scarabaeid subfamily Aphodiinae Leach, 1815 (when including Aegialiinae Laporte, 1840) con­sists of about 3200 species in 14 tribes and around 280 genera (Nikolajev 2008; Skelley 2008; Minkina 2020; Catalogue of Life 2021). Revisionary work has been recently accomplished for most of the New World fauna (PES pers. observation), yet new species are still being discovered and need description. The genus Haroldiellus (Type species: Aphodius sallei Harold 1863), consists of two species which are known from the United States south to Colombia and Jamaica, Hispaniola and the U.S. Virgin Islands in the West Indies. Here we describe a third spe­cies in the genus Haroldiellus Gordon and Skelley, 2007, present a key to the species in the genus, and provide diagnoses and updated distributions for H. lansbergei (Harold, 1874) and H. sallei (Harold, 1863).
