Etymology. The epithet is a noun in apposition that honors the Cacique Guaitipán  (or better known by her Spanish name transliteration, Gaitana), one of the maximum leaders and lady of the indigenous people that inhabited the central and eastern region of the Central Mountain Range of the Colombian Andes, among which are the Andaquí, Avirama, Guanaca, Páez, Pinao, Pijao, Timaná and Yalcón people. Indigenous heroin, renowned by her brave and fierce defense of their territories against the Spanish invaders.

Diagnosis. Males of A. guaitipan  sp. nov. are similar to those of A. sikuani  sp. nov. and A. tanimuca  sp. nov. by the shape of the RTA. However, they can be distinguished from those by their wider RTA, with the retro-dorsal lobe longer and wider, and the retro-ventral lobe turned prolaterally, with a retrolateral macroseta at its base ( Figs 4a –bView FIGURES 4, 20h –IView FIGURES 20). Females of A. guaitipan  sp. nov. are similar to those of A. quinini  sp. nov. by their general disposition of internal structures of the epigyne, but they can be distinguished from those by their shorter copulatory ducts, with the posterior epigynal border not concave, and a rounded epigynal pocket ( Figs 4c –dView FIGURES 4, 24c, 24iView FIGURES 24).
