Neotibicen similaris apalachicola, a new cicada subspecies

Filed under: David Marshall,Kathy Hill,Neotibicen,United States — Dan @ 6:28 am

A new subspecies of the Similar Dog-Day Cicada has been described in the paper A new Neotibicen cicada subspecies (Hemiptera: Cicadidae) from the southeastern USA forms hybrid zones with a widespread relative despite a divergent male calling song by David C. Marshall and Kathy B. R. Hill (Zootaxa, Vol 4272, No 4). The cicada is named Neotibicen similaris apalachicola.

This cicada lives in Florida, Georgia & Alabama, and hybridizes with the other Similar Dog-Day Cicada sub-speces, Neotibicen similaris similaris. The document is available on biotaxa.org.

A morphologically cryptic subspecies of Neotibicen similaris (Smith and Grossbeck) is described from forests of the Apalachicola region of the southeastern United States. Although the new form exhibits a highly distinctive male calling song, it hybridizes extensively where it meets populations of the nominate subspecies in parapatry, by which it is nearly surrounded. This is the first reported example of hybridization between North American nonperiodical cicadas. Acoustic and morphological characters are added to the original description of the nominate subspecies, and illustrations of complex hybrid song phenotypes are presented. The biogeography of N. similaris is discussed in light of historical changes in forest composition on the southeastern Coastal Plain.

You will find song samples and maps on the Insect Singers website.
