Kennedy, A. C. and C. R. Bartlett. 2014. Systematics of Caenodelphax Fennah (Hemiptera: Fulgoroidea: Delphacidae) and description of the new genus Flavoclypeus. Transactions of the American Entomological Society 140: 17-65.
Will have to update Caenodelphax and Delphacodes, plus add the new genus Flavoclypeus (soon).

The genus pages - especially for Delphacidae - are slowly being updated to include a more detailed literature (which should include all the literature for the original species descriptions), with links to Biodiversity Heritage Library for the older literature (and a few links to more recent online journals) as applicable and as I have time - adding these links is a surprisingly ponderous task. BHL has much of the pre-1923 (i.e., not in copyright) literature.
Other updates I intend to make are linking host plant names to USDA PLANTS or Tropicos, adding links to other websites or illustrations, updating the molecular information section, and sometimes adding keys to species from published sources or additional illustrations. In some cases I am adding a critical synonymy list. These updates may take a long time to complete.
Also, some soon-to-be published articles are going to move some species, which will motivate some of these changes.
I have added a simple list providing the higher classification of Delphacidae (i.e., subfamilies and tribes, with all valid genera placed). This list provides links to the delphacid genus-pages that I have made.
Jan. 23, 2014
I have added a checklist of of Delphacidae of Australia. It is skeletal at the moment, but will become more filled out over the next several months. Thanks to Glenn Bellis for this.
Jan. 14, 2014
A draft page on planthopper phylogenetics (so far above the family level) has been added. It requires more work, but is reasonably coherent.
Jan. 8, 2014
Newly described planthopper taxa.
Florida Entomologist 96(4) (not online as of this writing) has the description of a new delphacid genus and species from Argentina - Lepidelphax pistiae Remes Lenicov. I'll update my website to include this taxon soon.
Also, there is a new Omolicna (Derbidae) described from Florida that will be published soon.
December 26, 2013
Content for all planthopper genera North of Mexico has now been uploaded (some genera of Flatidae were intentionally delayed because they would annotate some taxonomic changes from Bartlett et al. (in press), which I anticipate being published in January (or so) 2014).
Next tasks include slowly updating pages to include synonymy lists, links to Biodiversity Heritage Library (and elsewhere), expanding the literature (especially for Delphacidae), finishing the phylogenetics overview, adding commentary regarding higher taxa, including additional images, and adding information from a variety of side projects, including Planthoppers of Costa Rica (based mainly on literature), Hemiptera of the Great Smoky Mtns National Park, and - hopefully - Delphacidae of Australia (and so on).
I will add pages for selected Neotropical genera as photographs become available.
There will be a substantive update following the publication of Bartlett et al. (as Memoirs #50 in Memoirs of the American Entomological Society).
Nov. 15, 2012
Content for nearly all planthopper genera North of Mexico (except Gaetuliini, Tropiduchidae, at this point) has been uploaded. Development of content has slowed a little because of the birth of my son (on Oct. 18), and subsequently by hurricane Sandy. I hope to have content for the remaining 10 genera by the end of the calender year.
I also have additional delphacid species photographed and will work on uploading that content once I finish with the Gaetuliini.
Unrelated to this website, but of interested to the larger community (particularly here at the University of Delaware) is that Tom Wood's treehopper collection at Cornell has been curated and a list is now available online here at the Cornell University insect collection.
Sept 3, 2012
I have uploaded content for Acanaloniidae,
Kinnaridae for genera north of Mexico (front page here). This leaves Dictyopharidae, Flatidae, Nogodinidae, Tropiduchidae and a key to family to go. Dictyopharidae next.
Interesting mystery - this photo was taken of some delphacids on the grass Paspalum in Florida:
They appear to me (and Steve Wilson) to be Tagosodes
, probably approximatus; but we will need to look at a tail to be sure (there are some other possibilities, less likely, and not previously reported from Florida). I am not aware of Tagosodes approximatus being found in abundance before. Hopefully I'll be able to look at some specimens to be sure.
Update: These are Tagosodes albolineosus on Paspalum repens.
Aug. 3, 2012
Okay - I'm not good about putting updates here.
Anyway - new pub:
Kennedy, A. C., C. R. Bartlett, and S. W. Wilson. 2012. An annotated checklist of the delphacid planthoppers (Hemiptera: Delphacidae) of Florida with the description of three new species and the new genus, Meristopsis. Florida Entomologist 95(2): 395-421. (http://journals.fcla.edu/flaent/issue/view/3805)
The digital library has been updated substantially
And major updates happening here
June 20, 2011
I've had a major update to the parasitoids of Delphacidae courtesy of Dr. Eduardo Virla and Dra. Erica Luft Albarracín (División Control Biológico de Plagas, Laboratorio de Enemigos Naturales de Plagas Agrícolas del NOA, PROIMI Biotecnologia - CONICET, Tucumán, Argentina; http://www.biocontroltucuman.com.ar/). They have provided a list of delphacid parasites, their hosts, literature and other information. The updated page is here.
I very much appreciate the update from Dr. Virla and Dra. Luft Albarracín. Thank you -
Dr. Virla has a dryinid site here: www.parasitoides.com.ar.
May 30, 2011
I now have a web page completed for all New World genera (here). I still would like to add pages for a few Old World genera that are of concern - which would be linked from the 'Economic Importance' or 'Species of Special Concern' pages. I'll be adding content to these pages as materials, time, and inspiration allow.
March 21, 2011
The 19th annual aggregation at Little Orleans campground in Maryland will be held June 3-5 2011 (arrive Friday, depart Sunday). The trip was originally started in 1989 by the late Tom Wood as an informal aggregation of treehopper workers, students, friends and significant others. Now, while the Membraskiteers still form the core of the group (an example of phylogenetic inertia?), entomological interests of the group is more diverse. It still provides a great opportunity to talk and collect with others passionate about insects.
To obtain further information, please contact me. Campsites are somewhat limited, and I need to plan food on Saturday evening, so please let me know if you plan on attending. Participants are expected to provide their own tents, food, and camping gear, and to share in the cost of the group campground registration and the group meal provided on Saturday evening.
Other News -
There are now web pages for all genera of New World Asiracinae (there is a link to each tribe, and from each tribe a link to each genus), Plesiodelphacinae, and Kelisiinae. I still have Stenocraninae, and the Tropidocephalini and Saccharosydnini within the Delphacinae to complete.
March 4, 2011
I've been creating web pages for all New World genera and genera with potentially invasive species. At this writing, I have 5 more genera before I am done with the 73 genera of Delphacini. The pages provide a species list of the genus, host records, comments on economic importance, specimen photos, and selected references. Of course I will be updating and improving these pages over time.
We can now post PDFs into the 1940-present bibliographic database. PDF's have been getting uploaded quickly - about 1,000 uploaded as of this writing. Most of the PDFs are just scans of photocopies. We will be improving these as opportunity allows (I would be happy to accept PDF contributions).
The list of New World species has been updated a number of times. We are working on a database for New World species - it is expected to replace the text listing of species that I posted some time back.
Lots of little changes...
Also, Looking for specimens of this undescribed genus. These specimens are from Arizona (on Muhlenbergia). I have specimens from Arizona and Mexico.

The interactive morphology guide has been posted here.
I've updated and compiled the Nearctic and Neotropical species list into a single list, which I have posted under "New World Species". With a little more editing I'll post a PDF. Photos of each genus will follow, probably after IT reconfigures the pages I've created for the list.
I've also begun to post PDFs for the Pre-1940 digital library. Posting PDFs for the 1940-present library is hung up because of a technical glitch for the moment.
August 3, 2010
I've updated the South American delphacid checklist - adding a new species and added the species from Juan Fernandez and Chiloe Islands, which for some reason were not there. I've also updated the specimens wanted section, again.
A beta version of the morphology guide will be posted after we've had a little more time to work with it.
June 25, 2010
The morphology guide is almost ready. I uploaded a screenshot this morning.
I'll be presenting at the 13th International Auchenorrhyncha Congress (and 7th International Workshop on Leafhoppers and Planthoppers of Economic Significance) held in Vaison-la-Romaine in the south of France in a couple of days.
The "specimens wanted" checklist has been updated.
May 3, 2010
The species checklists for both North and South America have been updated.
(I had missed the Juan Fernández Islands entirely!) I've also updated the
numbers of New World species annotated on the 'scope' page.
The interactive morphology guide is coming along....
April 2, 2010
This site came online Sept. 2009.
I'll post significant changes, updates or other events here.
This site is new, so contact me with comments or questions.
in particular, let me know if you find any errors, or something
that needs to be explained better.
