We describe here a new species in the genus Disersus Sharp, 1882 from the Otongachi Reserve in Ecuador. Disersus otongachi sp.nov. is externally similar to other representatives of the genus, however, this species can be clearly distinguished for significantly longer antennae and the unique shape of the male genitalia.

The riffle beetle genus\ Disersus\ is known to occur from Panama throughout the tropical regions of South America; only Panamanian species,\ Disersus longipennis\ Sharp, was previously described from Central America. The new species,\ Disersus uncus,\ the first species\ Disersus\ reported from Costa Rica, is described and the distinguishing morphological characters of the two species now known from Central America are described and illustrated. A key is provided to distinguish the two species.
