The holotype was discovered during a review of the insect collection of the IEXA. All we know is that it was collected in the year 2001 by students of the Biology Faculty during a collecting trip in the environs of the city of Puebla. Unfortunately, the exact collecting data were not noted—a well-known problem with unexperienced students. Thus, we can be only sure that the holotype was collected near Puebla City or at least in the State of Puebla.</p> <p>Material studied: Holotype: ♂, “ México, alrededores / Ciudad de Puebla. / Recolecta 2001 / Colector desconocido” [printed], “Holotipo / Cybister poblanus / Arce-Pérez y Novelo-Gutiérrez det. / 2021” [red, printed] (IEXA) (see Fig. 1c). The holotype lacks three antennomeres of each antenna as well as the claws of the left fore-leg and of the left hind-leg.</p> </div>	http://treatment.plazi.org/id/4E7F87DEFFA5FFBDFF74003EC305FECD	Public Domain	No known copyright restrictions apply.
