Natural history collections worldwide house billions of specimens, representing one of the most globally important biobanks. In recent years, the advent of next‐generation sequencing has significantly reduced the challenges of obtaining considerable genetic information from historical museum specimens. Crickets in the Australian tribe Eurepini Robillard are a good example of a taxon in which such museomic data have particularly strong potential to advance systematic knowledge, because comprehensive sampling requires decades of work over a very wide area. The tribe currently comprises 64 described species in five genera. Previous studies conflict in the generic relationships inferred for this tribe, all of which are poorly resolved, being based on limited data and sampling. In addition, there has so far been no systematic research for this tribe with extensive taxon sampling, and therefore, the consequence for genus boundaries remains to be investigated. To investigate phylogenetic relationships within Eurepini, we first applied the genome skimming approach to obtain molecular data from a comprehensive sample of Eurepini museum specimens. Of the 69 specimens sampled representing 61 described species, mainly including holotype specimens, we obtained 50 complete and 11 partially complete mitogenomes. Three nuclear genes (H3, 18S, and 28S) were also partially recovered for nearly all of these specimens. Phylogenetic analyses performed with mitogenomes plus three nuclear genes using maximum likelihood and Bayesian inference generated well‐supported and highly congruent topologies. Eurepini was strongly recovered monophyletic with eight well‐defined groups. These groups are used to revise the systematics of the tribe based on a combination of molecular phylogenetics and morphology. The phylogenetic results support the current definition of three genera (Eurepa Walker, Arilpa Otte & Alexander and Eurepella Otte & Alexander), lead us to redefine three genera (Salmanites Chopard, Napieria Baehr and Piestodactylus Saussure), and define and describe two new genera: Miripella Robillard, Tan & Su gen.nov. and Arrakis Robillard, Tan & Su gen.nov. Our results reinforce the importance of natural history collections as a repository for information on biodiversity and genetics, and provide the first comprehensive and robust phylogenetic framework for future systematic and evolutionary studies of Eurepini.

Colonization, speciation and extinction are dynamic processes that influence global patterns of species richness.sup.1-6. Island biogeography theory predicts that the contribution of these processes to the accumulation of species diversity depends on the area and isolation of the island.sup.7,8. Notably, there has been no robust global test of this prediction for islands where speciation cannot be ignored.sup.9, because neither the appropriate data nor the analytical tools have been available. Here we address both deficiencies to reveal, for island birds, the empirical shape of the general relationships that determine how colonization, extinction and speciation rates co-vary with the area and isolation of islands. We compiled a global molecular phylogenetic dataset of birds on islands, based on the terrestrial avifaunas of 41 oceanic archipelagos worldwide (including 596 avian taxa), and applied a new analysis method to estimate the sensitivity of island-specific rates of colonization, speciation and extinction to island features (area and isolation). Our model predicts--with high explanatory power--several global relationships. We found a decline in colonization with isolation, a decline in extinction with area and an increase in speciation with area and isolation. Combining the theoretical foundations of island biogeography.sup.7,8 with the temporal information contained in molecular phylogenies.sup.10 proves a powerful approach to reveal the fundamental relationships that govern variation in biodiversity across the planet. Using a global molecular phylogenetic dataset of birds on islands, the sensitivity of island-specific rates of colonization, speciation and extinction to island features (area and isolation) is estimated., Author(s): Luis Valente [sup.1] [sup.2] [sup.3] [sup.4] , Albert B.

20. Hearing and acoustic interaction in mosquitoes

571.1 ,QL Zoology - Abstract
Johnston, who discovered the mosquito auditory organ at the base of the antennae 150 years ago, speculated that audition was involved in mating behaviour. Indeed, the Johnston's organ (JO) is now known to detect the whine of flying mosquitoes. Analysis of sound recordings of flight tones from tethered, flying, mosquitoes revealed that opposite-sex pairs, when within their acoustic near-fields, attempt to frequency-match the harmonic components of their flighttones. Same-sex pairs actively avoid frequency-matching. Mosquitoes of the species Toxorhynchites brevipalpis, where the flight-tone frequencies of males and females are similar, attempt to match the fundamental frequency of their flight-tones. Haemophilic, vector-carrying mosquitoes Culex quinquefasciatus and Anopheles gambiae ss, where the fundamental frequency of the male flight tone is about 1.5 times that of the female, frequency-match harmonic components of their flight tones. Usually the male's 1st harmonic with the 2nd harmonic of the female flight-tone. In Burkina Faso, where two morphologically similar molecular forms aggregate in the same swarms but rarely hybridise, frequency-matching of flight-tones may perform a pre-mating barrier and a form of subspecies recognition. We discovered that frequency-matching occurred significantly more frequently between same-form male-female pairs of flying, tethered mosquitoes, than when each member of the pair was of a different molecular form. The bandwidth and tuning of sound-evoked flagellum vibrations and the JO's electrical responses to this mechanical input were measured using laser interferometry and extracellular electrodes, respectively. For the first time we showed that distortion products, recorded from the flagellum and JO, could provide the neural basis for frequency-matching at frequencies beyond the range of the JO's electrical responses. We also discovered that spontaneous oscillations of the antennae are produced by physiologically-sensitive mosquitoes. Through temperature-control and injection of pharmacological agents into the JO, evidence is presented advocating dynein as the molecular motor responsible for powering these oscillations.

- Abstract
Over the last three decades, insects have been utilized to provide a deep and fundamental understanding of many human diseases and disorders. Here, we present arguments for insects as models to understand general principles underlying hearing loss. Despite ∼600 million years since the last common ancestor of vertebrates and invertebrates, we share an overwhelming degree of genetic homology particularly with respect to auditory organ development and maintenance. Despite the anatomical differences between human and insect auditory organs, both share physiological principles of operation. We explain why these observations are expected and highlight areas in hearing loss research in which insects can provide insight. We start by briefly introducing the evolutionary journey of auditory organs, the reasons for using insect auditory organs for hearing loss research, and the tools and approaches available in insects. Then, the first half of the review focuses on auditory development and auditory disorders with a genetic cause. The second half analyses the physiological and genetic consequences of ageing and short‐ and long‐term changes as a result of noise exposure. We finish with complex age and noise interactions in auditory systems. In this review, we present some of the evidence and arguments to support the use of insects to study mechanisms and potential treatments for hearing loss in humans. Obviously, insects cannot fully substitute for all aspects of human auditory function and loss of function, although there are many important questions that can be addressed in an animal model for which there are important ethical, practical and experimental advantages.

Paragryllodini Hugel & Desutter-Grandcolas, n. tribe Type genus. Paragryllodes Karny, 1909, here designated. Diagnosis. At this stage, one single genus is included in this new tribe. The diagnosis of Paragryllodini, therefore, is that of Paragryllodes (see infra). Remark. Paragryllodes was tentatively placed in the subtribe Mexiaclina Gorochov, 2014 under the tribe Paragryllini Desutter, 1987 (Gorochov 2015). Molecular data clearly indicate that Paragryllodes is not related to Paragryllini. We therefore propose here the new tribe Paragryllodini n. tribe for the genus Paragryllodes, which represents a well-supported monophyletic clade within the Paragryllinae subfamily. In the molecular phylogeny of Chintauan-Marquier et al. (2013, 2016), the Paragryllodes clade is very wellsupported within the Phalangopsidae clade E2 (Chintauan-Marquier et al. 2016: Fig. 4; 100% ML bootstrap support, 1 posterior probability), a result confirmed with a more extended data set (Warren et al. 2019 and in prep.).

Seychelles, Silhouette, near Mare aux Cochons, over 1000 feet (Bolivar (1912). Type material. Lectotype female (designated by Gorochov 2006), Seychelles, Silhouette island [′Silhouette′, ′08, Seychelles Exp. 21′, ′′type′, ′Figured specimen′, ′Holotype′, ′Seychellia gen. n. nitidula sp. n. ′, ′ Seychelles, Percy Sladen Trust Expedition, 1913-170′, “ syntype] (NHM). Other material examined. Seychelles, Silhouette, Jardin Marron vers Mt Pot à eau, 550 m, vue de nuit, 1 female (2010SEYSH200), 5.x.2010, S. Hugel, MNHN-EO-ENSIF12094. Molecular sampling. LDG 375 in Warren et al. (2019). Remarks. Seychellesia nitidula is only known by females, but both molecular data (Chintauan-Marquier et al. 2013, 2016) and morphology (see below) indicate that Seychellesia nitidula belongs to Paragryllodes Karny, 1909 and is not related to the other species from the Seychelles described under the name Seychellesia (i.e. Seychellesia patellifera Bolivar, 1912 and Seychellesia longicercata Bolivar, 1912), for which we describe here the new genus Seselia Hugel & Desutter-Grandcolas, n. gen. S eychellesia nitidula shares the following characters with Paragryllodes: shiny cuticula; eyes strongly protruding; fastigium lower than head dorsum, and separated from it by a transverse furrow; median ocellus in frontal position, apical on fastigium; maxillary palpi moderately elongate, article 4 distinctively shorter that articles 3 and 5; pronotum sulcated; LL more or less perpendicular to DD; female copulatory papilla forming a sclerotized chamber (Fig. 2D).
