Cicadas of the genera Derotettix in Argentina and Okanagodes in the south-western United States resemble each other in colour, live on salt-tolerant plants (Atriplex spp. etc.), nearly match the colour of their respective host plants and produce songs above the range of avian hearing. The Argentine cicadas are smaller, but have nearly identical thermal limits for activity measured by the minimum temperature for flight (20-24 ∞C) and a body temperature at heat torpor (48-49 ∞C). The species shift activity from basking sites to shade at temperatures above 37 ∞C, although O. gracilis rises to a significantly higher temperature (40.7 ∞C) than its congener (38.2 ∞C) or Derotettix (37.2 ∞C). The thermal tolerances are the highest reported for cicada species. A third group using halophytes in Argentina (Babras sonorivox) has similar temperature tolerances and is cryptically coloured. The genera are convergent with respect to morphology, coloration, body size, behaviour, habitat choice and host plant selection. The similarities of thermal tolerances and their influence on behaviour can be viewed as parallelism because the underlying mechanisms are the same in all species studied.

A BSTRACT Analysis of museum specimens has added to the cicada fauna of Belize, El Salvador, Guatemala, and Honduras. Information on the cicada fauna reported in the literature as well as the first records of cicada species to the fauna are reported here to provide a more accurate understanding of cicada diversity in each country and the region. The new records represent an increase of 75, 14, 110, and 320%, respectively, to the cicada faunal diversity of each country.

North America has a diverse cicada fauna with multiple genera from all three Cicadidae subfamilies, yet molecular phylogenetic analyses have been completed only for the well-studied periodical cicadas (Magicicada Davis). The genus Tibicen Latreille, a large group of charismatic species, is in need of such work because morphological patterns suggest multiple groups with complicated relationships to other genera in the tribe Cryptotympanini. In this paper we present a molecular phylogenetic analysis, based on mitochondrial and nuclear DNA, of 35 of the 38 extant USA species and subspecies of the genus Tibicen together with their North American tribal allies (Cornuplura Davis, Cacama Davis), selected Tibicen species from Eurasia, and representatives of other Eurasian and Pacific cryptotympanine genera. This tree shows that Tibicen contains several well-supported clades, one predominating in eastern and central North America and related to Cryptotympana Stål and Raiateana Boulard, anoth...
Reevaluation of the Diceroprocta texana Species Complex (Hemiptera: Cicadoidea: Cicadidae)
Annals of the Entomological Society of America, 2010
The Diceroprocta texana species complex is currently composed of Diceroprocta texana texana and Diceroprocta texana lata Davis, 1941. We analyzed physiological, morphological, and biogeography to determine whether these taxa in fact represent two distinct species rather than subspecies. There are statistically signiÞcant differences in morphological, acoustic, and thermal parameters as well as the biogeographic patterns of the two taxa. From these data, we suggest that the two taxa actually represent two species and that D. texana lata be elevated to species full species rank with the name Diceroprocta lata Davis, 1941 n. stat. We provide the Þrst records of D. lata collected in the United States.

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 morphological cladistic analysis. A set of paraphyletic deep-level clades formed by African genera are together named as Tettigomyiinae 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, Lacetas...
Elevation of a Subspecies of tibicen (Hemiptera: Cicadoidea: Cicadidae) to a Full Species
The Southwestern Naturalist, 2011
The Tibicen bifidus species complex is composed of T. b. bifidus and T. b. simplex . We analyzed biogeographical, morphological, and physiological parameters to determine if these taxa represent two species. There are significant differences in biogeography, as well as selection of host-plant and several morphological characteristics. Comparisons of their calling songs approach statistical significance. Sound-pressure level of alarm calls and thermal responses of the two taxa do not differ significantly. Our data suggest that the two taxa represent distinct species.

Periodical cicadas in the genus Magicicada Davis (Hemiptera: Cicadidae) of brood II emerged in the eastern United States of America in 2013. In Connecticut, only Magicicada septendecim (Linnaeus) had been recorded until this emergence when Magicicada septendecula Alexander and Moore was found on Totoket Mountain in North Branford, Connecticut, United States of America. This discovery represented the northeastern-most record of this species. In two 0.25-ha plots where M. septendecula and M. septendecim emerged and chorused, species of Carya Nuttall (Juglandaceae) comprised 59.9–63.7% of the total basal area, with Carya glabra (Miller) Sweet, accounting for 43.9–60.0%. In one plot, 31.6% of the total basal area was Fraxinus americana Linnaeus (Oleaceae). By using the proportion of exuviae of M. septendecula (hind tibial length<6.3 mm) and M. septendecim (length ⩾ 6.3 mm) near trees and the mean number of emergence holes per 0.25-m2 quadrat (1.88), it was estimated that 1487 M. sept...
