Abstract

We here propose a new monotypic butterfly genus Scriptor Nakahara & Espeland, n. gen. to accommodate a new species, S. sphenophorus Lamas & Nakahara, n. sp., described and named herein. Scriptor sphenophorus n. gen. and n. sp. is a relatively common and widespread butterfly species which is recovered as a member of the so-called ‘‘Splendeuptychia clade’’ in the nymphalid subtribe Euptychiina, based on our molecular phylogenetic analysis using a maximum likelihood approach. Nevertheless, its sister group is not confidently resolved in any analysis, supporting a relatively distant relationship to any described genus as well as our decision to establish a new monotypic genus. We further discuss the proposed taxonomy in the light of frequent criticism of the description of monotypic taxa, as well as emphasize the importance of incorporating multiple evidence when describing new genera, illustrated by reference to several recent generic descriptions in this subtribe.
