Ladidelfuloj (latine didelphimorphia ) estasbiologia ordo de malgrandajmamuloj el la subklaso demarsupiuloj . Ilin unufoje difinis la zoologoTheodore Nicholas Gill en 1872. Aparte konata genro el la ordo, al kiu aludas ankaŭ la orda nomo, estas ladidelfoj , kaj ene de tiu genro precipe la specioordinara didelfo .
Pri terminoj, de kiuj esperantlingvaj nomoj ĝis nun ne indikitas, notiĝas la latina, parte ankaŭ hispana kaj/aŭ angla nomo, ĉar la bestoj hejmas en Ameriko kaj tie la hispana kaj angla estas la plej disvastiĝintaj lingvoj (portugalaj nomoj de tiuj bestoj kiuj vivas en Brazilo ankaŭ tre bonvenus). Kompreneble aparte bonos esperantlingvaj terminoj kaj koncernaj artikoloj, sed la listo en nuna formo nur estas modesta komenco de klasifiko. La ordigo cetere estas el la anglalingva samtema artikolo - tie estas referencoj pri iuj aparte novaj klasifikeroj.
