Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)

Abstract

The Cicadetta montana species complex includes six cicada species from the West-Palaearctic region. Based on acoustic diagnostic characters, a seventh species Cicadetta cantilatrix sp. nov. belonging to the complex is described. The type-locality is in France but the species distribution area extends to Poland, Germany, Switzerland, Austria, Slovenia, Macedonia and Montenegro. The calling song sequence consists of two phrases with different echemes. This calling pattern clearly differs from those produced by all other members of the complex, including C. cerdaniensis, previously mistaken with the new species. This description increases the acoustic diversity observed within a single cicada genus and supports the hypothesis that sound communication may play a central role in speciation.

Complex within a Complex: Integrative Taxonomy Reveals Hidden Diversity in Cicadetta brevipennis (Hemiptera: Cicadidae) and Unexpected Relationships with a Song Divergent Relative

“…In these cases taxon assignment to the various Cicadetta brevipennis group taxa is based on biogeography and must be verified especially for black dotted populations. Some of the records were previously published, essentially records of the cerdaniensis group [2,38–42,65,71–79]. *Brown dots are observations of Cicadetta brevipennis without assignment to a subspecies in Central Italy.…”

“…In the first step, Cicadetta cerdaniensis s. l. was recognized as a group of different taxa characterized by the group-typical basic repetition of shorter echemes importantly modulated in power and species-specific, additional elements of various complexities [42,43]. Two species were described with qualitatively different songs: Cicadetta cantilatrix Sueur & Puissant, 2007 and Cicadetta anapaistica Hertach, 2011.…”

Biogeography of the Cicadas (Hemiptera: Cicadidae) of North America, North of Mexico

“…We illustrate the distribution of each species currently known to inhabit North America, north of Mexico. We attempt to associate the distributions with phytogeographic regions if possible and host plants if the data exist since cicadas are often limited in their distribution by the phytogeographic region they inhabit [18,21,27,[29][30][31]49,[51][52][53][54][55][56][57]. We have also elevated subspecies to species rank in part based on geographic separations [27,29,30].…”

The genusPacarinaDistant, 1905 (Hemiptera: Cicadidae) with the description of a new species

“…The species of the morphologically similar Cicadetta montana (Scopoli) complex have been distinguished primarily based on differences in calling song parameters (e.g. Puissant and Boulard 2000;Sueur and Puissant 2007;Gogala et al 2008Gogala et al , 2009Hertach 2011 The minimum flight temperature (Mann-Whitney P = 0.0240) is the only thermal response to show a statistically significant difference between P. shoemakeri sp. nov. and P. puella ( Table 2).…”
