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, Lacetasini n. tribe, Macrotristriini n. tribe, Malagasiini n. tribe, Nelcyndanini n. tribe, Pagiphorini n. tribe, Pictilini n. tribe, Psaltodini n. tribe, and Selymbriini n. tribe). Tribe Tacuini n. syn. is synonymized with Cryptotympanini, and Tryellina n. syn. is synonymized with an expanded Tribe Lamotialnini. Tribe Hyantiini n. syn. is synonymized with Fidicinini. Tribe Sinosenini is transferred to Cicadinae from Cicadettinae, Cicadatrini is moved to Cicadettinae from Cicadinae, and Ydiellini and Tettigomyiini are transferred to Tettigomyiinae n. stat from Cicadettinae. While the subfamily Cicadinae, historically defined by the presence of timbal covers, is weakly supported in the molecular tree, high taxonomic rank is not supported for several earlier clades based on unique morphology associated with sound production.

Higher-Level Phylogeny and Reclassification of Lampyridae (Coleoptera: Elateroidea)
Abstract Fireflies (Lampyridae Rafinesque) are a diverse family of beetles which exhibit an array of morphologies including varying antennal and photic organ features. Due in part to their morphological diversity, the classification within the Lampyridae has long been in flux. Here we use an anchored hybrid enrichment approach to reconstruct the most extensive molecular phylogeny of Lampyridae to date (436 loci and 98 taxa) and use this phylogeny to evaluate the higher-level classification of the group. None of the currently recognized subfamilies were recovered as monophyletic with high support. We propose several classification changes supported by both phylogenetic and morphological evidence: 1) Pollaclasis Newman, Vestini McDermott (incl. Vesta Laporte, Dodacles Olivier, Dryptelytra Laporte, and Ledocas Olivier), Photoctus McDermott, and Araucariocladus Silveira & Mermudes are transferred to Lampyridae incertae sedis, 2) Psilocladinae Mcdermott, 1964status novum is reestablished for the genus Psilocladus Blanchard, 3) Lamprohizini Kazantsev, 2010 is elevated to Lamprohizinae Kazantsev, 2010status novum and Phausis LeConte is transferred to Lamprohizinae, 4) Memoan Silveira and Mermudes is transferred to Amydetinae Olivier, and 5) Scissicauda McDermott is transferred to Lampyrinae Rafinesque.

The Cicadoidea comprise two families, the Cicadidae and the Tettigarctidae. This paper evaluates the status and taxonomy of all named Cicadoidea fossils belonging to the Cicadidae. Shcherbakov (2009) has previously revised the Tettigarctidae. Two new genera are described, Camuracicada gen. n. and Paleopsalta gen. n., for Camuracicada aichhorni (Heer, 1853) comb. n. and Paleopsalta ungeri (Heer, 1853) comb. n. A lectotype is designated for Cicada emathion Heer, 1853. Cicada grandiosa Scudder, 1892 is transferred to Hadoa Moulds, 2015 as Hadoa grandiosa comb. n.; Oncotympana lapidescens J. Zhang, 1989 is transferred to Hyalessa China, 1925 as Hyalessa lapidescens comb. n.; Meimuna incasa J. Zhang, Sun & X. Zhang, 1994 and Meimuna miocenica J. Zhang & X. Zhang, 1990 are transferred to Cryptotympana Stål, 1861 as Cryptotympana incasa comb. n. and Cryptotympana miocenica comb. n.; Tibicen sp. aff. japonicus Kato, 1925 is transferred to Auritibicen as Auritibicen sp. aff. japonicus comb. n., and Terpnosia sp. aff. vacua Olivier, 1790 is transferred to Yezoterpnosia Matsumura, 1917 as Yezoterpnosia sp. aff. vacua comb. n. The generic placement of two other fossils is changed to reflect current classification, those species now being Auritibicen bihamatus (Motschulsky, 1861) and Yezoterpnosia nigricosta (Motschulsky, 1866). Two species, Davispia bearcreekensis Cooper, 1941 and Lithocicada perita Cockerell, 1906, are transferred from the subfamily Cicadinae to the Tibicininae, tribe Tibicinini. Cicadatra serresi (Meunier, 1915) is also transferred from the Cicadinae to the Cicadettinae because the Cicadatrini have recently been transferred from the Cicadinae to the Cicadettinae (Marshall et al. 2018). Miocenoprasia grasseti Boulard and Riou, 1999 is transferred from the tribe Prasiini to the Lamotialnini. Tymocicada gorbunovi Becker-Migdisova, 1954 is transferred from the Dundubiini to the Cryptotympanini; Paracicadetta oligocenica Boulard & Nel, 1990 is transferred from the Cicadettini to the Pagiphorini and Minyscapheus dominicanus Poinar et al., 2011 is assigned to the Taphurini. Names of species once considered to belong in Cicadidae, but now excluded, are listed with explanation.more » « less

BackgroundLucidotini is a diverse tribe of lampyrine fireflies present throughout the New World, Europe, and Asia. Most of the over 30 genera have overlapping diagnoses, largely due to a lack of revisionary and phylogenetic studies. Widespread convergence in sensory morphology, traditionally used in genus-level diagnoses, further compounds the taxonomic issues surrounding the Lucidotini. Recent work has cast light on the value of terminalia and genitalic traits for Lucidotini taxonomy and called for a more thorough screening of morphological characters. Of special interest are basal outgrowths of the phallus (i.e., ventrobasal processes)—currently only known inAlychnusKirsch andPhotinusLaporte–that can be quite informative at the species level, but its variation within Lucidotini remains poorly studied. Most Lucidotini species remain only superficially described, while internal characters—including those of terminalia and genitalia—which could inform species identification and phylogenetic relatedness, remain unknown. Upon studying eight Lucidotini species superficially looking likePhotinusandPhotinoidesMcDermott—all of which bearing long ventrobasal processes–we raised the hypothesis that they belonged to a genus yet to be recognized. MethodsHere, we analyzed 97 morphological characters of 32 lampyrid species spanning 17 of 30 Lucidotini genera under Bayesian Inference. ResultsWe found evidence for the recognition and description ofSaguassugen. nov.to include seven new species (Saguassu acutumsp. nov.,Saguassu grossiisp. nov.,Saguassu manauarasp. nov.,Saguassu rebellumsp nov.,Saguassu rourasp. nov.,Saguassu serratumsp. nov.andSaguassu sinuosumsp. nov.), in addition toPhotinus dissidensOlivier ((transferred herein, thus generatingSaguassu dissidenscomb. nov.), for which we also designate a lectotype and two paralectotypes). This previously neglected lineage of Lucidotini spans four South American biomes: Amazon, Atlantic Rainforest, Cerrado, and Pampa. Interestingly,Saguassuspecies span a gradient of morphologies related to signaling: fromLampyris-style ventrally bulging eyes, tiny antennae and no lanterns; intermediate eyes and antennae, with complete lanterns as inPhotinus; to small eyes and long antennae and small lanterns as in manyLucidotaLaporte.Saguassugen. nov.was consistently found closely related to the three other Lucidotini taxa with ventrobasal processes (i.e.,Alychnus,Photinoides, andPhotinus). We provide an occurrence map of and a dichotomous key toSaguassuspecies, thoroughly compare this genus with co-occurring Lucidotini genera, and suggest steps towards a revision of the Lucidotini tribe.more » « less

Petalacmis Olivier, 1908 is a poorly known genus of firefly endemic to South America and is currently the only member of the subfamily Lampyrinae, tribe Lampyrini known to occur on the continent. Here, we describe a new species, Petalacmis triplehorni sp. nov. from Bolivia and compare it to the two other described species in the genus. A key to Petalacmis species based on male traits, as well as illustrations of morphological features, are given in detail for the first time. We present unique, previously neglected traits of Petalacmis species and compare them to other Lampyrinae.more » « less

Investigations of the freshwater isopod genus Lirceus Rafinesque, 1820 in Ohio and Kentucky USA reveal surprising results regarding the taxon- omy of the genus. Given the incomplete states of their original descriptions, Lirceus fontinalis Rafinesque, 1820 and Lirceus richardsonae Hubricht & Mackin, 1949 were subjected to molecular and morphological analyses and then redescribed from as geographically near to their type locali- ties as possible. The range of L. fontinalis is circumscribed to include sites now only in Fayette County, Kentucky, while the range of L. richardsonae is expanded to include much of western Ohio. In addition, a new species from Delaware County, Ohio was identified and is described. This unexpected species showed relatively little affinity to L. fontinalis/richardsonae and may represent a species from a different faunal assemblage. The presence of these two isopod lineages suggests a contact zone in Ohio due to postglacial dispersal from the east and from the south.more » « less
