First Treehopper in Niue
Wallace, M. S.; Anderson, D.; Deitz, L. L. 2016a. Antianthe expansa (Germar): first treehopper (Hemiptera: Membracidae) recorded from Pacific Island Nation of Niue. Proceedings of the Entomological Society of Washington 118(4):650-653.

Vouchers of Antianthe expansa collected in Niue, 21 January 1996, on tomatoes: 1-2, adult (1, anterior; 2, lateral), 3-4 nymph (3, anterior; 4, lateral).

This work documents Antianthe expansa (Figs. 1-4) on tomatoes in Niue, however, a prior record from Hawaii and an unconfirmed report from Tonga are also discussed. Thus, this New World treehopper is reported not only from the Neotropical and Nearctic regions, but also in the Oceanic region.

An Alarm Signal to Guard Treehopper Eggs Against Mymarids?
Miranda, X. 2016a. Egg-guarding behavior of the treehopper Ennya chrysura (Hemiptera: Membracidae): female aggregations, egg parasitism, and a possible substrate-borne alarm signal. Revista de Biologia Tropical 64(3): 1209-1222. [available online]

Substrate-borne signals produced by females of E. chrysura while guarding their egg masses against parasitism may alert neighboring females of an attack, thus lowering the overall rate of parasitism by certain mymarid wasps. Miranda observed that under natural conditions females tend to deposit their eggs close to other egg-guarding females. Also, in the laboratory, females exposed to playbacks of another female’s disturbance signal react more quickly and defensively to a tactile stimulus.

Publications on New World Treehoppers from 2016
Benassi, V. L. R. M.; Valente, F. I.; Souza, C. A. S.; Benassi, A. C.; Sakakibara, A. M. 2016a. Biodiversidade e sazonalidade de cigarrinhas (Hemiptera: Membracidae) em cacaueiros. EntomoBrasilis 9(1): 41-46. [available online; in Portuguese, with English abstract].

This study lists and illustrates 30 membracid species associated with Theobroma cacao in Linhares, Espirito Santo State, Brazil. Seasonality data are given for 5 of 8 species confirmed to feed on cacao. Horiola picta was by far the most abundant species.

Published online March 2016, this work includes: Sundarion flavopiceum and S. marmoratum n. spp.; S. compressicornis (Fairmaire, 1846), n. comb.; and notes on S. notable de Souza [Evangelista de Souza] and Rothéa.

Flynn, D. J.; Wheeler, A. G., Jr. 2016a. Micrutalis pallens Fowler (Hemiptera: Membracidae): first U.S. records, host-plant association, description of male, and redescription of female. Proceedings of the Entomological Society of Washington 118(3):345-353.

This paper extends the distribution of M. pallens to the Nearctic region, with records on Thurber’s desert honeysuckle (Acanthaceae: Anisacanthus thurberi) in Arizona and New Mexico. Prior reports of this treehopper were all from the Neotropics (Argentina, Guatemala, Guyana, Mexico, Panama, and Venezuela). M. pallens is compared to five other species Micrutalis reported from the Southwest.

First published online, this paper describing Selenacentrus wallacei, new genus and species, is now available in the print version of the journal. This treehopper occurs on a few members of the plant family Fabaceae (Prosopis, Pithecellobium, and Acacia) in Texas and northern Mexico.

Both adult males and females of A. grossa sequester tropane alkaloids from the host B. suaveolens.

Wheeler provides extensive field observations of these membracids in the Appalachians of North Carolina, South Carolina, and Tennessee.

Notes and Photos from the 24th Annual Treehopper Gathering
Treehopper enthusiasts representing 10 of the 50 States, as well as China, Colombia, and Russia, attended the 24th Annual Treehopper Gathering, 5 to 7 June 2016, Little Orleans, Maryland. Attendees (photo 1, left to right) included: Dmitry Dmitriev, Ashley Kennedy, Charles Bartlett, Andrew Short, Nate Nazdrowicz, Anthony Gonzon, Yang Wang, Anthony Deczynski, Laura Catalina González-Mozo, Matt Wallace, Lawrence Barringer, Dawn Flynn, Vlad Dmitriev, Lewis Deitz, Jason Owens, Mark Rothschild, Kelley Tilmon, Karen McGowan, Kerry McGowan, Stuart McKamey, Hava Amsbury, Dennis Kopp, Eli Wyman, and, in photo 2, Felipe Gonzalez-Mozo (he napped during the group photos).

Aside from one torrential downpour, the weather was fine. As usual, base camp activities centered around the picnic shelter and ranged from treehopper mounting, sorting, and identification (photo 3 [left to right Laura G.-M., Stu McK., and Yang W.]) to lending and exchanging specimens, trading literature, socializing, playing Frisbee, showing off prized treehopper t-shirts (photo 4, shirt presented to Dennis K. from friends at North Dakota State University, 1990), and enjoying the Saturday evening feast of meats and veggies (photos 5-7: 5, Charles B. grilling steak; 6, Ashley K. grilling veggies; 7, Anthony G. smiling over his fried turkey). An exciting development was that Dmitry Dmitriev (Illinois Natural History Survey, Champaign) will be collaborating with our existing Treehoppers Teams to assist in developing the Treehoppers Database in TaxonWorks. Thus, Dmitry is now officially part of our Taxa Content Team, Nomenclatural Database Team, and References Database Team.

Many participants also had fun collecting (photos 8-11: 8, Dmitry D.; 9, Matt W. with beating sheet and Vlad D. with sweep net; 10, Mark R., Kerry McG., and Karen McG.) and exploring areas around the campground (photo 11, Vlad D. and Yang W. at Fifteen Mile Creek). Notably, Matt W. collected his first nymph of Heliria excelsa, which he reared to the adult stage, thus filling a significant gap in his ongoing research on the nymphs of the tribe Telamonini. Among numerous other specimens collected were Telamona ampelosidis [male] (photo 12), Entylia carinata (13), and a fine-looking nymph of the genus Glossonotus (photo 14).

Because 2017 will mark our 25th Annual Treehopper Gathering, we will likely extend next year’s gathering by an extra day or two! We hope to announce the final dates 2 or 3 months before the event, most likely it will include the first weekend of June. Already folks are thinking about special t-shirt designs to celebrate our Silver Anniversary.
