This species, together with I. damasoi and I. michellae , form a distinctive group with male mandibular shape being the main diagnostic character. The mandibles of this species are usually shorter and thicker, with the inner tooth of left mandible strongly developed and with a distinctive triangular shape. Another character shared within this group is the pronotum being less transverse. This is the only species currently known from Pasco State, situated between Huánuco and Junín States in Peru.
