Abstract
The Mahanarva group comprises five genera: Sphenorhina, Aeneolamia, Pachypterinella, Kanaima, and Mahanarva (sensu lato). A cladistic analysis is presented to define the relationship between these genera and subgenera, and the species of Kanaima, testing its monophyly. The data matrix comprises 18 taxa with 49 characters. The outgroup used in the analysis was Neosphenorhina ocellata. Kanaima is represented by six previously described species and a new species. Based on the phylogenetic analysis Kanaima is a polyphyletic group. The Mahanarva group is supported by three synapomorphies and the following relationships are recovered for the Mahanarva group: (N. ocellata (S. rubra ((A. colon, A. postica) (((M. (I.) rubripennis, M. (I.) integra) (K. vittata, K. fortunata)) ((K. dubia (K. radiata (M. (M.) liturata, M. (M.) consita))) (K. katzensteinii ((K. n. sp., P. fusca) (K. fluvialis)))))))). Based on the cladogram five new combinations are proposed: Mahanarva (Ipiranga) fortunata (Lallemand, 1924) n. comb.; Mahanarva (Ipiranga) vittata (Walker, 1851) n. comb., Mahanarva (Mahanarva) dubia (Stancik & Cavichioli, 2003) n. comb.; e, Mahanarva (Mahanarva) radiata (Walker, 1851) n. comb.; Kanaima fusca (Lallemand, 1927) n. comb.References
