Major Changes to the Tibicen genera

Sometimes you wake up and the whole world is different. See this cicada:

… when I went to sleep she was a Tibicen tibicen tibicen, but now I know she is a Neotibicen tibicen tibicen. 10 years ago, she was a Tibicen chloromera. 130 years ago, she was Cicada tibicen. Cicada names change as researchers discover their differences.

Two new papers have split the Tibicen (or Lyristes) genera into many genera: Tibicen (European Tibicen), Auritibicen (Tibicen of Asia/Japan), Neotibicen (mostly eastern North American Tibicen), and Hadoa (Tibicen of the western United States).

The first paper is Description of a new genus, Auritibicen gen. nov., of Cryptotympanini (Hemiptera: Cicadidae) with redescriptions of Auritibicen pekinensis (Haupt, 1924) comb. nov. and Auritibicen slocumi (Chen, 1943) comb. nov. from China and a key to the species of Auritibicen by Young June Lee, 2015, Zootaxa 3980 (2): 241–254. This paper establishes the new genera Auritibicen, and the members of the Tibicen/Lyristes genera fall into that genera. Here is a link. So, Tibicen flammatus aka Lyristes flammatus of Japan, for example, becomes Auritibicen flammatus.

The second paper is Molecular phylogenetics, diversification, and systematics of Tibicen Latreille 1825 and allied cicadas of the tribe Cryptotympanini, with three new genera and emphasis on species from the USA and Canada (Hemiptera: Auchenorrhyncha: Cicadidae) by Kathy B. R. Hill, David C. Marshall, Maxwell S. Moulds & Chris Simon. 2015, Zootaxa 3985 (2): 219–251. This paper establishes the Neotibicen (Hill and Moulds), and Hadoa (Moulds) genera. This paper also sought to establish the Subsolanus genera for the Asian Tibicen/Lyristes species but the previously mentioned paper by Young June Lee has precedence because it was published first. Link to paper.

To recap, European Tibicen/Lyristes are Tibicen

… Asian Tibicen/Lyristes are now Auritibicen. Mostly-eastern North American Tibicen are now Neotibicen, and Western North American Tibicen are now Hadoa. Note that, the catagorization is not due to location, but to genetic and physiological evaluation (read the papers).

Needless to say this website and others have a lot of name changing to do, but in the mean time, here’s where the North American species fall out:

Cool new cicada website: Insect Singers

Filed under: David Marshall,Kathy Hill,Sounds — Dan @ 3:29 pm

Hey,

If you’re interested in North American cicada species, and you’re looking for sound files of those cicada’s songs, check out Insect Singers, a new website from cicada researchers David Marshall and Kathy Hill. It has dozens of audio samples. Awesome!

Versatile Aggressive Mimicry of Cicadas by an Australian Predatory Katydid

Filed under: Australia,David Marshall,Kathy Hill — Dan @ 10:34 pm

David Marshall and Kathy Hill have discovered that a particular species of katydid mimics the wing-flick of female cicadas to lure male cicadas to their certain doom.

We have found that predatory Chlorobalius leucoviridis katydids (Orthoptera: Tettigoniidae) can attract male cicadas (Hemiptera: Cicadidae) by imitating the species-specific wing-flick replies of sexually receptive female cicadas. This aggressive mimicry is accomplished both acoustically, with tegminal clicks, and visually, with synchronized body jerks. Remarkably, the katydids respond effectively to a variety of complex, species-specific Cicadettini songs, including songs of many cicada species that the predator has never encountered.
