Nummulites alsharhani n.sp. (Group: Nummulites distans) is taxonomically analysed and described from fossiliferous limestones on the western limb (Tle4) of Jabal Hafit anticline, Al-Ain area, and from Al-Faiyah Range Mountains (northeast of Jabal Al Aqabah, U.A.E.). This species evolved in parallel lineage with the phyletic line of Nummulites maximus d’ARCHIAC, 1850. The phylogeny of the lineage of Nummulites alsharhani is from tight to lax while the opposite trend is found in the lineage of Nummulites maximus. This species conforms well with that described from Turkey by DECROUEZ & SELCUK (1981) as Nummulites aff. maximus.
