Abstract: The external morphology of phallus of 56 species of Neotropical Tenebrionids (Col. Heteromera) belonging to three subfamilies, 5 tribes and 16 genera is described and illustrated. Often some comparisons are made with closely allied species. In one case also a different, new subspecies is illustrated (Austrocaribius venezuelensis araguae ssp. n.). The morphology of phallus proves to be of great importance for a differentiation of some genus inside a tribe (e.g. Stictoderia among Eopitragini) and of some groups of species within a genus (e. g. Antillean and South Caribbean Diastolinus). In both cases an agreement with what we know of geology and paleogeography of the inhabited territory is very remarkable. General comments are made about importance male genitalia can have in cladistic and phenetic classifications; also the bearing of geographic distribution of some taxa in phylogenetic trees is stressed. The research is still in progress.Journal: Folia entomologica hungaricaJournal abbreviation: Folia ent. hung.ISSN: 0373-9465Publisher: , Editor(s): Mahunka, S.
