F7D7D3B393255165995BFCB74CF5C147.taxon	diagnosis	Diagnosis. Agathomerus espinosaorganistai sp. nov. is similar to A. signatus (Klug) and it is distinguished by the following combination of character states: pronotum with anterior groove interrupted medially (Fig. 5 F), scutellum with apex subtruncate, male metafemur fusiform and metatibiae curved (Fig. 5 B), and metaepisternum (Fig. 5 G) with anterior region coarsely, setigerously punctate, rest impunctate and glabrous. In A. signatus the pronotum has a well-defined anterior groove, scutellum apex is rounded, male metafemur are kidney-shaped and strongly curved, and metaepisternum has anterior and posterior regions punctate and pubescent, with rest impunctate and glabrous.	en	Rodríguez-Mirón, Geovanni M., López-Pérez, Sara (2025): Redescription of the Neotropical genus Agathomerus (Coleoptera, Megalopodidae, Megalopodinae) and description of three new species from Mexico.
