Z. P. Metcalf Collection of Literature on Auchenorrhyncha

Filed under: Allen F. Sanborn,Papers and Documents — Dan @ 8:58 pm

Here is information about a research resource for Auchenorrhyncha researchers. I’m posting at the request of Lew Dietz and Allen F Sanborn.

Z. P. Metcalf Collection of Literature on Auchenorrhyncha

Dear Colleagues,

We would like to make you aware of an exciting resource that is available to you at the Special Collections Research Center at NCSU Libraries in Raleigh, North Carolina.

The Zeno Payne Metcalf Entomology Research Collection is an outstanding resource for scholars. The link to the finding aid is here:

https://www.lib.ncsu.edu/findingaids/mc00220

And the link to the associated database for individual publications is here: http://metcalf.lib.ncsu.edu/metcalf/

If you would like to make an appointment to view any materials in person, or to request a copy of a publication remotely, please email us at: library_specialcollections@ncsu.edu

We typically need 2-3 business days to pull selected materials from off-site storage. More information about visiting the Special Collections Research Center can be found here: https://www.lib.ncsu.edu/scrc/using-materials

Finally, we are pleased to let you know that low-resolution copies (PDFs) only cost 50 cents per page, but, if you bring a camera (no flash allowed) or cell phone, you can take photographs at no cost in the Special Collections Reading Room. If you are unable to visit in person, we can still provide low-resolution copies (PDFs) to you for the fees outlined above. For security reasons, arrangements to pay using a major credit card (preferred) or bank transfer, should be made by telephone. Copyright law applies; see: https://www.lib.ncsu.edu/scrc/copyright

If you have any further questions about the Metcalf materials or copyright, please don’t hesitate to contact us at library_specialcollections@ncsu.edu

New paper on the molecular phylogeny of the cicadas and tribe and subfamily classification

A new paper has been published titled A molecular phylogeny of the cicadas (Hemiptera: Cicadidae) with a review of tribe and subfamily classification by David C. Marshall, Max Moulds, Kathy B. R. Hill, Benjamin W. Price, Elizabeth J. Wade, Christopher L. Owen, Geert Goemans, Kiran Marathe, Vivek Sarkar, John R. Cooley, Allen F. Sanborn, Krushnamegh Kunte, Martin H. Villet, Chris Simon.

The paper was published in Vol 4424, No 1 of Zootaxa. Link to paper.

In a nutshell: These researchers compared the DNA of a variety of cicadas to determine how they are related evolutionarily and how they should be organized in terms of tribes and sub-families.

Abstract:

A molecular phylogeny and a review of family-group classification are presented for 137 species (ca. 125 genera) of the insect family Cicadidae, the true cicadas, plus two species of hairy cicadas (Tettigarctidae) and two outgroup species from Cercopidae. Five genes, two of them mitochondrial, comprise the 4992 base-pair molecular dataset. Maximum-likelihood and Bayesian phylogenetic results are shown, including analyses to address potential base composition bias. Tettigarcta is confirmed as the sister-clade of the Cicadidae and support is found for three subfamilies identified in an earlier morpho- logical cladistic analysis. A set of paraphyletic deep-level clades formed by African genera are together named as Tettigo- myiinae n. stat. Taxonomic reassignments of genera and tribes are made where morphological examination confirms incorrect placements suggested by the molecular tree, and 11 new tribes are defined (Arenopsaltriini n. tribe, Durangonini n. tribe, Katoini n. tribe, Lacetasini n. tribe, Macrotristriini n. tribe, Malagasiini n. tribe, Nelcyndanini n. tribe, Pagi- phorini n. tribe, Pictilini n. tribe, Psaltodini n. tribe, and Selymbriini n. tribe). Tribe Tacuini n. syn. is synonymized with Cryptotympanini, and Tryellina n. syn. is synonymized with an expanded Tribe Lamotialnini. Tribe Hyantiini n. syn. is synonymized with Fidicinini. Tribe Sinosenini is transferred to Cicadinae from Cicadettinae, Cicadatrini is moved to Ci- cadettinae from Cicadinae, and Ydiellini and Tettigomyiini are transferred to Tettigomyiinae n. stat from Cicadettinae. While the subfamily Cicadinae, historically defined by the presence of timbal covers, is weakly supported in the molecular tree, high taxonomic rank is not supported for several earlier clades based on unique morphology associated with sound production.

Brood X Stragglers Emerge in Ohio

Filed under: Brood X,Gene Kritsky,Magicicada,Periodical Stragglers — Dan @ 9:59 pm

Gene Kritsky, author of Periodical Cicadas. The Plague and the Puzzle, let us know that many of what are likely Brood X cicada stragglers have emerged around the Mount St. Joseph University campus, in Cincinnati, Ohio. It’s likely that cicadas are emerging elsewhere in the Cincinnati area.

This is significant because Brood X cicadas should not emerge until 2021.

Quick facts:

  • Gene Kritsky is a periodical cicada expert and Dean of the School of Behavioral and Natural Sciences and Professor and of Biology at Mount St. Joseph University. Read more.
  • Brood X is a massive brood of Magicicada (the genus) periodical (the lifecycle type) cicadas that are set to emerge in 2021 in 15 states.
  • A straggler is a periodical cicada that emerges off-schedule, often a few years before or after the rest of its Brood.

Second edition of Cicadas of North American North of Mexico

Filed under: Allen F. Sanborn,Maxine E. Heath — Dan @ 5:31 am

Allen F. Sanborn and Maxine S. Heath have released the second edition of their book Cicadas of North American North of Mexico.

What’s new:

The second edition includes the addition of four new genera, the removal of two genera, and the addition of a few new species that were described since the first edition. We also added distributional data for all species.

New paper: Massospora cicadina) hijacks the sexual signals of periodical cicadas

A new paper, A specialized fungal parasite (Massospora cicadina) hijacks the sexual signals of periodical cicadas (Hemiptera: Cicadidae: Magicicada), has been published by John R. Cooley, David C. Marshall & Kathy B. R. Hill, in Scientific Reports 8, Article number: 1432 (2018).

Read the paper online.

In a nutshell: the fungus infects males and causes them to exactly mimic the mating behavior of female cicadas, thus infected males end up spreading the fungus to uninfected males.

Abstract:

Male periodical cicadas (Magicicada spp.) infected with conidiospore-producing (“Stage I”) infections of the entomopathogenic fungus Massospora cicadina exhibit precisely timed wing-flick signaling behavior normally seen only in sexually receptive female cicadas. Male wing-flicks attract copulation attempts from conspecific males in the chorus; close contact apparently spreads the infective conidiospores. In contrast, males with “Stage II” infections that produce resting spores that wait for the next cicada generation do not produce female-specific signals. We propose that these complex fungus-induced behavioral changes, which resemble apparently independently derived changes in other cicada-Massospora systems, represent a fungus “extended phenotype” that hijacks cicadas, turning them into vehicles for fungus transmission at the expense of the cicadas’ own interests.

And now, because I need an image for the post: a meme:

Fungus Bae

Cicadas, when infected, are called “salt shakers of doom”. Add that to the meme “Salt Bae”, and the image makes sense.
