03CF402BFFA9FFF46FADFA403B24671D.taxon	discussion	Remarks. Cenophengus fagerstromi sp. nov. is morphologically similar to C. hnogamui, but can be distinguished by the color of the pronotum, interocular distance, and terminal maxillary palpomere length. In C. fagerstromi sp. nov., the pronotum is bicolored, dark brown with anterior fifth yellowish, whereas in C. hnogamui, the pronotum is unicolored, dark brown. The interocular distance, in C. fagerstromi sp. nov., is 2 times longer than the eye width in dorsal view, while just 1.5 times longer than eye width in C. hnogamui. The terminal maxillary palpomere is shorter than the preceding three in C. fagerstromi sp. nov., but as long as the preceding three in C. hnogamui.	en	Vega-Badillo, Viridiana, Roza, André Silva (2025): Description of two new species of Cenophengus (Coleoptera: Phengodidae: Cenophenginae), with an assessment of their phylogenetic position in the genus.
