J·H·亞當(J. H. Adam)和哈米德(Hafiza A. Hamid)在2006年發現了納奎友丁豬籠草(N. naquiyuddinii)。納奎友丁豬籠草生長在沙巴(Sabah)和婆羅洲的Keningau-Kimanis Road和Trus Madi山腳下,海拔1400~1425m的開闊次生植被中。亞當和哈米德認為“因為兩眼豬籠草和納奎友丁豬籠草存在許多形態上的差異,所以他們不能歸為同一個物種,但兩眼豬籠草和納奎友丁豬籠草仍有著近緣關係。”但是另一些學者認為,兩眼豬籠草和納奎友丁豬籠草的差異太小了,不足以講其分成兩個種。此外,這些學者認為納奎友丁豬籠草可能是暗色豬籠草(N. fusca)和兩眼豬籠草的自然雜交種。納奎友丁豬籠草的上位籠
