“…Similarly, a small sequence of clicks was recorded from one O. simulans female. These clicks were produced by rubbing the tegmina against the atrophic wing joined to the metanotum, and were similar to those recorded in Acrostira (Enderlein, 1929) and Purpuraria (Enderlein, 1929) (López et al 2008).…”

“…In Pamphagidae, alternative mechanisms of stridulation that do not involve the Krauss's organ have been described (Johnsen 1972;Ingrisch 1983;Llorente et al 1995;García et al 1996;Presa et al 2000;López et al 2008), but few studies suggested that Krauss's organ itself produces sounds. In some Thrinchinae, the upper side of middle tibiae have a row of teeth or tubercles that are rubbed by the wing, producing sound that is amplified by the tympanum.…”

In Pamphagidae, the Krauss's organ is located on both sides of the 2 nd tergite and its function is superficially known. It has been proposed to have a stridulatory function. This organ can be found in all Pamphagidae except the apterous genera. Rearing specimens of some species and observing mounted pamphagids allowed the author to observe that when the Krauss's organ is absent (most apterous species) the tympanum is also absent; further, he discovered specialized stridulatory structures on hind femurs of some taxa for sound emission. By rearing two Pamphagidae belonging to different genera, fragments of stridulations involving the Krauss's organ and specialized structures on the hind femur surface were obtained for the first time. Mapping the presence of these morphological characters onto the known Pamphagidae list revealed that specialization on the hind femur surface evolved multiple times in multiple geographical locations in winged species with a wrinkled Krauss's organ. The function of the sounds produced by the femur-Krauss's organ method remains to be studied.

“…[264,265] against a hardened file on the underside of the adjacent wing. Both the scraper and the file are optimized for chirping and are coupled to thin, rigid parts of the wing (see Section 3.2) to promote acoustic coupling (Figure 12A-D).…”

Over the course of their wildly successful proliferation across the earth, the insects as a taxon have evolved enviable adaptations to their diverse habitats, which include adhesives, locomotor systems, hydrophobic surfaces, and sensors and actuators that transduce mechanical, acoustic, optical, thermal, and chemical signals. Insect‐inspired designs currently appear in a range of contexts, including antireflective coatings, optical displays, and computing algorithms. However, as over one million distinct and highly specialized species of insects have colonized nearly all habitable regions on the planet, they still provide a largely untapped pool of unique problem‐solving strategies. With the intent of providing materials scientists and engineers with a muse for the next generation of bioinspired materials, here, a selection of some of the most spectacular adaptations that insects have evolved is assembled and organized by function. The insects presented display dazzling optical properties as a result of natural photonic crystals, precise hierarchical patterns that span length scales from nanometers to millimeters, and formidable defense mechanisms that deploy an arsenal of chemical weaponry. Successful mimicry of these adaptations may facilitate technological solutions to as wide a range of problems as they solve in the insects that originated them.

The genus Prionotropis Fieber, 1853 is revised. It is distributed in scattered areas of the Mediterranean region from Turkey in the East to Spain in the West. Overall, seven species are listed, namely P. maculinervis (Stål, 1878) (Turkey; P. urfensis Ramme, 1933 is here considered its synonym), P. willemsorum n. sp. (Greece, Epirus; previously considered P. appula), P. appula (O.G. Costa, 1836) (South Italy), P. hystrix (Germar, 1817) (Bosnia and Herzegovina, Slovenia, Croatia, NorthEast Italy; P. hystrix sontiaca is here synonymized), P. rhodanica Uvarov, 1923 resurrected status (France, Crau, Rhone delta; here considered a valid species), P. azami Uvarov, 1923 n. status (France, Var region; here considered a valid species), and P. flexuosa (Serville, 1838) (Spain; the ssp. pereezi Bolívar, 1921 and sulphurans Bolívar, 1921 are here considered its synonyms). A key to species is presented.Key words: Mediterranean area, female micropterism, sexual dimorphism, isolation, new species IntroductionAmong Thrinchinae, generally widespread in Asia, only Glyphotmethis Bei-Bienko, 1951, Asiotmethis Uvarov, 1943, Glyphanus Fieber, 1853 and Prionotropis Fieber, 1853 are present in Europe, but while the first three genera have a restricted distribution in the most eastern parts of Europe (Caucasia, Crimea, European Turkey, Greece and Macedonia: Ünal 2007a, 2007b, Willemse & Willemse 2008, the genus Prionotropis covers the entire Mediterranean area including the most western parts (Iberian peninsula). Interestingly, the genus is represented by isolated populations, some of which are recognized as different taxa; their taxonomic status has been debated for over one hundred years. A long series of specimens from different localities and different museums was studied in order to revise the taxonomy of the genus. Material and methodsSpecimens from the following museums were included in this study: 500 · Zootaxa 4059 (3) © 2015 Magnolia Press NBC Naturalis Biodiversity Center (National Museum of Natural History), Leiden NHM Natural History Museum, London NMW Naturhistorisches Museum, Vienna NTM Nazife Tuatay Müzesi, Ankara Some specimens were photographed with a Nikon Coolpix 4500 digital camera, mounted on a Wild M5 Stereomicroscope, and photos were integrated using the freeware CombineZP (Hadley 2008). Mounted specimens were measured with a digital calliper (precision 0.01 mm); the following measures were taken (all measurements in mm): Body length (TL=dorsal length from the fastigium of the vertex to the apex of horizontal hind femur); Pronotum length (PL=length of the pronotum along dorsal median line); Pronotum height (PH=maximum height of the pronotum); Hind femur length (HFL= maximum length of hind femur); Hind femur height (HFH=maximum height of hind femur); Tegmina length (TGL=maximum length of exposed tegmina).Analysis of mean differences of morphometric characters among species was performed with an ANOVA, after data normalisation by means of a Box-Cox transformation. All analyses were concluded with Tukey post...
