Abstract

Abstract. A new stem-orthopteran insect assignable to the – traditional – and the – cladotypic-defined – taxon Dana, 1864 is described based on abundant material collected from the Xiaheyan locality (Ningxia, China; Early Pennsylvanian). Intra-specific wing venation variability in n. sp. is appreciated based on wing pairs of single individuals, and on a complete series of conditions. Rare variants are reported. Details of head and leg morphology are documented: the new species possesses a five-segmented tarsus provided with paired claws and arolium, and labial palps with at least four segments, probably five. The nomenclatural section is conducted under the cladotypic nomenclatural procedure, but in a way largely consistent with the traditional usage. This experiment demonstrates that a combination composed of a genus level-taxon name previously associated with a definition and type material (e.g. Miamia), a specific epithet (e.g. maimai), and authorship information (e.g. Bethoux et al. 2012), with further mention to Miamia maimai or M. maimai, provides a suitable reference to the species under all nomenclatural procedures, including the traditional one. doi: 10.1002/mmng.201200008
