Jain Ramayana further rationalises or rather legitimizes them as Humans. Jain Munis describe 4 Kshatriya Vanshas: Suryavansha, Somavansha, Harivansha & Vidyadharavansha. Vanaras are considered proper Vidyadharas (of Nagavansh) who simply had clans organized with Monkey Banners.
Sant Ekanath Maharaja further legitimizes even Hanuman as being Ikshvakuvanshi, by stating that a portion of the Payasam bestowed by Agni to Maharaja Dasharatha was carried away by a Bird (soaring through AIR, Vayu) to Anjaneri where Anjani Mata consumed it & conceived Hanuman.
This Deccani version of Hanuman being linked to Bhagwan Shri Rama and by extension the Ikshvakuvansha is further extrapolated in all South-East Asian versions of Ramayana as well.
