2016-12-08
Chung-Ping Lin informs us a Chinese version of Maruyama’s book "Treehoppers: Incredible Insects" is being published this month (December 2016; ISBN:9789864431885). A few Taiwanese species have been added to the earlier edition (see archive of treehopper news: “Maruyama's 2011 book "Treehoppers: Incredible Insects," dated: 2012-08-03).

First Treehopper in Niue
2016-11-11
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?
2016-10-28
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

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.

Creão-Duarte, A. J.; Sakakibara, A. M. 2016a. Two new species of Sundarion (Hemiptera: Membracidae: Darninae) and taxonomic notes on two congeneric taxa. Zoologia 22(1):1-7.

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.

Morris, B. O.; Dietrich, C. H. 2016a. Hidden in plain sight: a remarkable new genus of Nearctic treehoppers (Hemiptera: Membracidae). Annals of the Entomological Society of America 109(3): 488-494. [in English, with Spanish abstract].

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.

Pinto, C. F.; Salinas, S.; Flores-Prado, L.; Echeverría, J.; Niemeyer, H. M. 2016a. Sequestration of tropane alkaloids from Brugmansia suaveolens (Solanaceae) by the treehopper Alchisme grossa (Hemiptera: Membracidae). Biochemical Systematics and Ecology 66: 161-165.

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

Wallace, M. S. 2016a. Telamona barbata Van Duzee 1908, reinstated junior synonym of T. decorata Ball 1903, and their respective lectotype designations (Hemiptera: Membracidae). Proceedings of the Entomological Society of Washington 118(3): 477-479.

Wallace designates, compares, and illustrates the male lectotypes.

Wheeler, A. G., Jr. 2016a. Thelia bimaculata (F.) and Vanduzea arquata (Say) (Hemiptera: Membracidae) in the southern Appalachians: new hosts in Robinia (Fabaceae) and nymphal use of abandoned cavities of the locust twig borer. Proceedings of the Entomological Society of Washington 118(3): 436-449.

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