  • Redefinition of the cicada tribe Hemidictyini Distant, 1905, status of the tribe Iruanini Boulard, 1993 rev. stat., and the establishment of Hovanini n. tribe and Sapantangini n. tribe (Hemiptera: Cicadidae)
Title: Redefinition of the cicada tribe Hemidictyini Distant, 1905, status of the tribe Iruanini Boulard, 1993 rev. stat., and the establishment of Hovanini n. tribe and Sapantangini n. tribe (Hemiptera: Cicadidae)
A recent paper by Ruschel & Campos (2019) on “leaf-winged” cicadas proposed a significant reorganization of the cicada tribe Hemidictyini Distant, 1905g, including synonymization of the monogeneric tribe Lacetasini Moulds & Marshall, 2018 following the results of a cladistic parsimony analysis of morphological characters. In this study, we reconsider and revise the morphological analysis of Ruschel & Campos and obtain new genetic data for Hemidictya. We find that their study suffers from a limited taxon sample, inappropriate outgroup selection, and misinterpretation of genitalic characters (uncus vs. claspers). We show that Hemidictyini sensu Ruschel & Campos includes members of multiple tribes and subfamilies, and we conclude that some of the taxonomic transfers by Ruschel & Campos are not supported. The two most similar and leaf-like cicadas, Hemidictya Burmeister, 1835 (South America) and Hovana Distant, 1905g (Madagascar), are probably not closely related but rather an excellent example of convergent evolution. Lacetasini is not a junior synonym of the Hemidictyini but a distinct part of the Tettigomyiinae Distant, 1905g as originally classified. We return or transfer the genera Lacetas Karsch, 1890, Iruana Distant, 1905g, Bafutalna Boulard, 1993, and Murphyalna Boulard, 2012 to the Lacetasini. With the transfer of all genera of Iruanina Boulard, 1993 and Bafutalnina Boulard, 1993 to Lacetasini and with Lacetas transferred to the Iruanina, Lacetasini n. syn. becomes a subjective junior synonym of Iruanini rev. stat. in the Tettigomyiinae. We assign Hovana to Hovanini n. tribe in the Tettigomyiinae and Sapantanga Distant, 1905g to Sapantangini n. tribe in the Tibicininae Distant, 1905b. We propose that Hemidictyini sensu novo contains only the genus Hemidictya and we assign the tribe to Tibicininae with a revised diagnosis.  more » « less

    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.

    Abstract

    The butterfly tribe Candalidini is geographically restricted to Australia and mainland New Guinea and its adjacent islands. With 60 species and subspecies, it represents a large radiation of Papilionoidea in the Australian region. Although the species‐level taxonomy is relatively well understood, the number of genera is uncertain, varying from two to eight. We reconstructed the phylogeny of the Candalidini based on a 13‐locus hybrid enrichment probe set (12.8 Kbp: COI, Thiolase, CAD, CAT, DDC, EF1‐a, GAPDH, HCL, IDH, MDH, RPS2, RPS5, Wingless), including all previously recognized genera and 76% (28/37) of the species‐level diversity of the tribe. Maximum likelihood analysis recovered the Candalidini as a strongly supported monophyletic group. In conjunction with morphological characters, the phylogeny provided a robust framework for a revised classification in which we recognize four genera, 37 species and 23 subspecies. The genusNesolycaenaWaterhouse & R.E. Turner is considered in synonymy withCandalidesHübner, and four other genera are not recognized, namely,HolochilaC. Felder,AdalumaTindale,ZetonaWaterhouse andMicroscenaTite. Of the four valid genera, theabsimilisgroup (23 species) is placed in the newly described genusEirmocidesBraby, Espeland & Müllergen. nov.(type speciesCandalides consimilisWaterhouse). Theerinusgroup (six species) is assigned toErinaSwainson, which is reinstated.Chrysophanus cyprotusOlliff is assigned toCyprotidesTite, which is also reinstated as a monotypic genus. The remaining seven species are placed inCandalides sensu stricto. Overall, we propose 47 new nomenclatural changes at the species and subspecies levels, including the synonymy ofHolochila biakaTite asEirmocides tringa biaka(Tite)syn. nov. et comb. nov.and recognition ofCandalides hyacinthinus gilesiM.R. Williams & Bollam as a distinct speciesErina gilesi(M.R. Williams & Bollamstat. rev. et comb. nov.A dated phylogeny using Bayesian inference in BEAST2 and biogeographical and habitat analyses based on the DEC model in BioGeoBEARS indicated that the ancestor of the Candalidini most likely evolved in rainforest habitats of the mesic biome in situ on the Australian plate of Southern Gondwana during the Eocene (c. 43 Ma). A major period of diversification occurred in the Miocene, which coincided with aridification of the Australian continent, followed by a further episode of radiation in montane New Guinea during the Plio‐Pleistocene.

    Abstract

    The Platypleurini is a large group of charismatic cicadas distributed from Cape Agulhas in South Africa, through tropical Africa, Madagascar, India and eastern Asia to Japan, with generic diversity concentrated in equatorial and southern Africa. This distribution suggests the possibility of a Gondwanan origin and dispersal to eastern Asia from Africa or India. We used a four‐gene (three mitochondrial) molecular dataset, fossil calibrations and molecular clock information to explore the phylogenetic relationships of the platypleurine cicadas and the timing and geography of their diversification. The earliest splits in the tribe were found to separate forest genera in Madagascar and equatorial Africa from the main radiation, and all of the Asian/Indian species sampled formed a younger clade nested well within the African taxa. The tribe appears to have diversified during the Cenozoic, beginningc. 50–32 Ma, with most extant African lineages originating in the Miocene or later, well after the breakup of the Gondwanan landmass. Biogeographical analysis suggests an African origin for the tribe and a single dispersal event founding the Asian platypleurines, although additional taxon sampling and genetic data will be needed to confirm this pattern because key nodes in the tree are still weakly supported. Two Platypleurini genera from Madagascar (PycnaAmyot & Audinet‐Serville,YangaDistant) are found to have originated by late Miocene dispersal of a single lineage from Africa. The genusPlatypleurais recovered as polyphyletic, withPlatypleura signiferaWalker from South Africa and many Asian/Indian species apparently requiring assignment to different genera, and a newPlatypleuraconcept is proposed with the synonymization ofAzanicadaVilletsyn.n.The generaOrapaDistant andHamzaDistant, currently listed within separate tribes but suspected of platypleurine affinity, are nested deeply within the Platypleurini radiation. The tribe Orapinisyn.n. is here synonymized while the tribe Hamzini is pending a decision of the ICZN to preserve nomenclatorial stability.

    Abstract

    The family Mutillidae (Hymenoptera) is a species‐rich group of aculeate wasps that occur worldwide. The higher‐level classification of the family has historically been controversial due, in part, to the extreme sexual dimorphism exhibited by these insects and their morphological similarity to other wasp taxa that also have apterous females. Modern hypotheses on the internal higher classification of Mutillidae have been exclusively based on morphology and, further, they include Myrmosinae as a mutillid subfamily. In contrast, several molecular‐based family‐level studies of Aculeata recovered Myrmosinae as a nonmutillid taxon. To test the validity of these morphology‐based classifications and the phylogenetic placement of the controversial taxon Myrmosinae, a phylogenomic study of Mutillidae was conducted using ultraconserved elements (UCEs). All currently recognized subfamilies and tribes of Mutillidae were represented in this study using 140 ingroup taxa. The maximum likelihood criterion (ML) and the maximum parsimony criterion (MP) were used to infer the phylogenetic relationships within the family and related taxa using an aligned data set of 238,764 characters; the topologies of these respective analyses were largely congruent. The modern higher classification of Mutillidae, based on morphology, is largely congruent with the phylogenomic results of this study at the subfamily level, whereas the tribal classification is poorly supported. The subfamily Myrmosinae was recovered as sister to Sapygidae in the ML analysis and sister to Sapygidae + Pompilidae in the MP analysis; it is consequently raised to the family level, Myrmosidae,stat.nov.The two constituent tribes of Myrmosidae are raised to the subfamily level, Kudakrumiinae,stat.nov., and Myrmosinae,stat.nov.All four recognized tribes of Mutillinae were found to be non‐monophyletic; three additional mutilline clades were recovered in addition to Ctenotillini, Mutillini, Smicromyrmini, and Trogaspidiini sensu stricto. Three new tribes are erected for members of these clades: Pristomutillini Waldren,trib.nov., Psammothermini Waldren,trib.nov., and Zeugomutillini Waldren,trib.nov.All three recognized tribes of Sphaeropthalminae were found to be non‐monophyletic; six additional sphaeropthalmine clades were recovered in addition to Dasymutillini, Pseudomethocini, and Sphaeropthalmini sensu stricto. The subtribe Ephutina of Mutillinae: Mutillini was found to be polyphyletic, with theEphutagenus‐group recovered within Sphaeropthalminae and theOdontomutillagenus‐group recovered as sister to Myrmillinae + Mutillinae. Consequently, the subtribe Ephutina is transferred from Mutillinae: Mutillini and is raised to a tribe within Sphaeropthalminae, Ephutini,stat.nov.Further, the taxon Odontomutillinae,stat.nov., is raised from a synonym of Ephutina to the subfamily level. The sphaeropthalmine tribe Pseudomethocini was found to be polyphyletic, with the subtribe Euspinoliina recovered as a separate clade in Sphaeropthalminae; consequently, Euspinoliina is raised to a tribe, Euspinoliini,stat.nov., in Sphaeropthalminae. The dasylabrine tribe Apteromutillini was recovered within Dasylabrini and is proposed as a new synonym of Dasylabrinae. Finally, dating analyses were conducted to infer the ages of the Pompiloidea families (Mutillidae, Myrmosidae, Pompilidae, and Sapygidae) and the ages of the Mutillidae subfamilies and tribes.

    In 2009, Jones and Deitz published a tribe-level taxonomic revision and reclassification of the cryptic, arboreal leafhopper subfamily Ledrinae Kirschbaum, 1868 (Hemiptera: Cicadellidae), based on cladistic analyses of 235 morphological features for 75 cicadellid species. Their evolutionary reconstructions found strong node support for a monophyletic ingroup comprising five lineages—each morphologically and geographically cohesive—and also identified numerous traditionally placed taxa (sensu Oman et al 1990) that did not belong. In light of the robustness of their results, the authors recognized the five independent ingroup clades as tribes of Ledrinae, and described three of these as new.
