Se tienen contribuciones recientes sobre su taxonomía; sin embargo, aún hacen falta más estudios al respecto. En este trabajo se describen 2 especies nuevas de Belonuchus procedentes de varios estados de México, las cuales fueron localizadas en el material entomológico de la Colección Nacional de Insectos de la UNAM. Las descripciones se acompañan con imágenes que ayudan al reconocimiento de las especies y se presenta una clave modificada que facilita su identificación. Además, se analizaron ejemplares de algunas especies ya conocidas que representan varios primeros registros estatales. Todo lo anterior ha derivado en el incremento de la riqueza nacional de especies de Belonuchus y en un conocimiento más completo sobre su taxonomía y distribución geográfica.]]></p></abstract>

There are recent contributions on their taxonomy; however, more studies are still needed in this regard. This paper describes 2 new species of Belonuchus from several states in Mexico, which were located in the entomological material of the National Insect Collection, UNAM. Descriptions are accompanied by images that help to recognize the species and a modified key is presented to facilitate their identification. In addition, several specimens of some already known species, which represent first state records, were analyzed. All of the above has resulted in an increase in the national richness of Belonuchus species and a more complete knowledge of its taxonomy and geographic distribution.]]></p></abstract>
