First description of ant-mutualism, nymphal morphology and vibrational signals in the genus Nicomia Stål (Hemiptera: Membracidae: Nicomiinae)

We report for the first time ant mutualism in treehoppers of the genus Nicomia Stål (Membracidae: Nicomiinae), observed within ant shelters constructed by ants of the genus Pheidole Westwood (Myrmicinae). The nymphs of Nicomia pulchella Albertson are described for the first time, and their morphological similarities with other membracid groups possessing cryptic nymphs are discussed. We recorded vibrational signals of N. pulchella produced within nymph and adult aggregations while interacting with ants, and signals made from two adults of Nicomia cf. jucunda Albertson.

Additionally, this study provides the first record of the genus Nicomia for Colombia.
