Lacordaire (1872) separated Desmiphorini from Apodasyini based on the position of the head: retractile in the former, nonretractile in the latter. Furthermore, he separated these two tribes from Estolini based on the shape of the mesocoxal cavities: open in Desmiphorini and Apodasyini , closed in Estolini. However, the position of the head is variable in genera of Desmiphorini , making the separation of these tribes, based on this feature, not useful. The shape of the mesocoxal cavities is identical in all species of Desmiphorini , Apodasyini and Estolini, making the separation between these tribes, as proposed by Lacordaire in his key, impossible. Linsley and Chemsak (1984) correctly considered the mesocoxal cavities closed in these three tribes. Actually, the mesocoxal cavities in all species of Desmiphorini (including Estolini and Apodasyini that were examined) have the same kind of mesocoxal cavities: closed, as in the middle image in figure 1 from Linsley and Chemsak (1984) , and not as in the lower image of the same figure. Thus, Lacordaire could not be considering the former as open and the latter as closed. Linsley and Chemsak (1984) also separated Estolini from Apodasyini in their key based on the presence of a dorsal sulcus on the mesotibiae of the former, which is absent in the latter. Although currently Estolini and Apodasyini are synonyms of Desmiphorini ( Monné 2017 ) , the previous comments are pertinent, because Atelodesmis belongs to Estolini sensu Lacordaire (1872) and Linsley and Chemsak (1984) (mesotibiae sulcate dorsally), while Atelodesmis piperita belongs to Apodasyini (mesotibiae not sulcate dorsally). Consequently, E. piperita cannot be placed in Atelodesmis . It agrees much more closely with Eupogonius LeConte, 1852 (a genus that would belong to Apodasyini ). Both Breuning (1974) and Linsley and Chemsak (1984) defined Eupogonius as having slender antennae, fringed with long setae, and lower eye lobes longer than the gena. Although usually they are distinctly long, the erect setae on the antennae of Eupogonius are somewhat variable in length. Also, the erect setae on the elytra are typically longer and more abundant. However, we believe that these features alone do not require a new genus for this species. Thus, we formally transfer Atelodesmis piperita to Eupogonius . Additionally, a new state record ( Oaxaca ), for the species, is recorded for Mexico . Material examined. MEXICO , Chiapas : 17 km W Tuxtla Gutiérrez , 3 males , 2 females , 4–6.X.1986 , E.
