New species of Megatibicen: Megatibicen harenosus

Filed under: Jeffrey A. Cole,Megatibicen,Tibicen — Dan @ 6:32 am

A new species of Megatibicen, named Megatibicen harenosus sp. n., has been described by Jeffrey A. Cole. It lives in the Mescalero-Monahans shinnery sands areas of New Mexico and Texas. It is very similar to Megatibicen (Neotibicen, Tibicen) tremulus, which itself looks a lot like dorsatus and dealbatus.

Here’s a link to the announcement of the paper. This is the abstract:

Megatibicen harenosus sp. n. is described from the Mescalero-Monahans shinnery sands of New Mexico and Texas, U.S.A. The new species is diagnosed from similar species, especially M. tremulus which it resembles closely, by male genital morphology, color pattern, calling song, and ecology. Seven characters from the male calling song are described from analysis of field recordings, of which all four temporal song characters are significantly different from M. tremulus. With one of the most southwestern distribution of any Megatibicen species, M. harenosus is a new addition to the rich, endemic, and understudied Mescalero-Monahans shinnery sands biota. The possibility that M. harenosus and M. tremulus are sister species is raised. The ecological, biological, and evolutionary species concepts support species status for M. harenosus, and an hypothesis of peripatric speciation in peripheral isolation is advanced.

Gigatibicen, Ameritibicen, Paratibicen

Gigatibicen
For some reason I associate “Giga” with “Gigabytes” and storage media like Flash drives, which explains this joke image.

Over the past two years there have been quite a few updates to the genera of the cicadas that were organized under the Tibicen genus earlier this decade.

The most recent paper by Young June Lee introduces the genera Gigatibicen, Ameritibicen, and Paratibicen 1. Earlier this year there was a paper by Allen Sanborn and Maxine Heath that introduced the genus Megatibicen 3, and in 2015 there was a paper by Kathy Hill and others that introduced Neotibicen and Hadoa 2.

See the end of the article for links to these papers, and related articles on CicadaMania.com.

The table below shows the names/synonyms (sub species have been removed to keep the table compact):

What is Megatibicen?!

Update (9/20): I guessed the species correctly: all the Large Flute Players.

Update (9/24): I neglected to note that there’s another paper out there by Young June Lee called Description of three new genera, Paratibicen, Megatibicen, and Ameritibicen, of Cryptotympanini (Hemiptera: Cicadidae) and a key to their species. Link to it here. This manuscript goes beyond one new genera, and instead introduces three: Paratibicen, Megatibicen, and Ameritibicen. Lee’s paper differs from Sanborn & Heath in that the large Neotibicen are spit into Megatibicen and Ameritibicen in Young’s document, but they’re all Megatibicen in Sanborn & Heath’s paper.

Megatibicen

Last night I had a rough night’s sleep. I tossed and turned all night long. I remember looking at the clock and seeing 4am, and thinking “tomorrow is ruined”. Sometime during the night I dreamt of finding thousands of molted Neotibicen exuvia clinging to shrubbery — a rare if not impossible sight in real life.

When I woke I checked my email and found a communication from David Marshall. David is well known and respected in the cicada world for many things including describing the 7th species of Magicicada with John Cooley (link to document), as well as being part of the team who defined the Neotibicen and Hadoa genera (link to paper)1.

David wrote to let me know that Allen F. Sanborn and Maxine S. Heath had published a new paper titled: Megatibicen n. gen., a new North American cicada genus (Hemiptera: Cicadidae: Cicadinae: Cryptotympanini), 2016, Zootaxa Vol 4168, No 3.(link).

So, what is MEGATIBICEN? Assumptions after the abstract.

Here is the abstract:

The genus Tibicen has had a confusing history (see summary in Boulard and Puissant 2014; Marshall and Hill 2014; Sanborn 2014). Boulard and his colleague (Boulard 1984; 1988; 1997; 2001; 2003; Boulard and Puissant 2013; 2014; 2015) have argued for the suppression of Tibicen and the taxa derivatived from it in favor of Lyristes Horváth. Boulard’s argument for suppression was first described in Melville and Sims (1984) who presented the case for suppression to the International Commission on Zoological Nomenclature with further comments made by Hamilton (1985), Boulard (1985), and Lauterer (1985). A lack of action resulted in additional comments being published in 2014 again supporting the retention (Sanborn 2014; Marshall and Hill 2014) or the suppression (Boulard and Puissant 2014) of Tibicen.

My guess, without reading the document, is that Megatibicen includes the larger North America Neotibicen species, including the “auletes group” (N. auletes, N. resh, N. figuratus, N. resonans), the “pronotalis group” (N. pronotalis, N. dealbatus, N. cultriformis) and the “dorsatus group” (N. dorsatus, N. tremulus), or a mix of these. N. auletes is the largest cicada in North America. “Mega” is the Greek word for “very large” or “great”. Word is that Kathy Hill and David Marshall also planned on describing a Megatibicen genus at one point, as well.

Whenever cicada names change it causes feelings of bemusement, discontentment and discomfort amongst some cicada researches and fans. I know I don’t like it because I have to update the names of cicadas in 100’s of places on this website ;). Some folks simply disagree with the folks writing the paper. Some people prefer former names because they sound nicer (e.g. N. chloromerus vs N. tibicen tibicen). Some people simply do not like change.
