Trogellus Paulsen, 2013

Type species. Trogellus herrmanni Paulsen.

Paulsen (2013) created the genus Trogellus to accommodate ten species from Central America, eight of which were new, placing them into three subgenera. At that time the genus was known from northeastern Mexico to the Costa Rica / Panama border area. The discovery of three specimens from the Darién Gap region of Panama, representing a new species described below, advances the distribution of the genus to extreme eastern Panama only a few kilometers from Colombia. In addition, males of the species T. maesi Paulsen have been recently collected for the first time. This allows for the first illustration of the dorsal habitus of males as well as of the male genitalia.
