Trogellus (Trogoides) maesi Paulsen, 2013

Trogellus maesi was described from two females from Selva Negra in Nicaragua, based on molecular data indicating that the species was distinct ( Paulsen 2013). Additionally, morphological characters such as the more sinuate metatibiae and narrower prosternum were present to diagnose the species. The collection of the first males of this species at the type locality by collector Ryo Ishikawa was reported to me recently (J.-M. Maes, pers. comm.), and a specimen generously sent to me by Mr. Ishikawa for study ( Fig. 9a View Figures 8–9 ). The male genitalia do possess the triangular lateral processes on the median lobe as expected by the species’ placement in the subgenus Trogoides Paulsen ( Fig. 9b View Figures 8–9 ). The parameres are similar to those of T. chapinitus Paulsen and T. hawksi Paulsen in being broad and placed laterally. The lateral processes are similar in shape to those of T. chapinitus , but begin closer to the base. Proximal to the lateral processes, the median lobe is distinctly wider than in T. chapinitus .
