One hundred and three new species of Trigonopterus weevils from Sulawesi.

ABSTRACT: The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia, the Moluccas, and the Sunda Islands. Only one species, Trigonopterusfulvicornis (Pascoe, 1885) was so far recorded from Sulawesi. Based on focused field-work the fauna from Sulawesi and nearby islands is here revised. We redescribe T.allotopus Riedel newly recorded for Sulawesi and describe an additional 103 new species: T.abnormis sp. n., T.adspersus sp. n., T.ambangensis sp. n., T.ampanensis sp. n., T.analis sp. n., T.arachnobas sp. n., T.armipes sp. n., T.artemis sp. n., T.asterix sp. n., T.barbipes sp. n., T.bonthainensis sp. n., T.carinirostris sp. n., T.castaneipennis sp. n., T.celebensis sp. n., T.cirripes sp. n., T.collaris sp. n., T.costatulus sp. n., T.curvipes sp. n., T.crenulatus sp. n., T.cricki sp. n., T.darwini sp. n., T.ejaculatorius sp. n., T.fuscipes sp. n., T.gracilipes sp. n., T.heberti sp. n., T.hirsutus sp. n., T.humilis sp. n., T.hypocrita sp. n., T.idefix sp. n., T.impressicollis sp. n., T.incendium sp. n., T.incognitus sp. n., T.indigenus sp. n., T.inhonestus sp. n., T.invalidus sp. n., T.jasminae sp. n., T.klabatensis sp. n., T.kolakensis sp. n., T.kotamobagensis sp. n., T.laevigatus sp. n., T.lampros sp. n., T.latipennis sp. n., T.lompobattangensis sp. n., T.luwukensis sp. n., T.mahawuensis sp. n., T.manadensis sp. n., T.mangkutanensis sp. n., T.matalibaruensis sp. n., T.mesai sp. n., T.minahassae sp. n., T.moatensis sp. n., T.modoindingensis sp. n., T.nanus sp. n., T.nitidulus sp. n., T.obelix sp. n., T.ovalipunctatus sp. n., T.ovatulus sp. n., T.pagaranganensis sp. n., T.palopensis sp. n., T.paracollaris sp. n., T.pauper sp. n., T.pendolensis sp. n., T.posoensis sp. n., T.prismae sp. n., T.procurtus sp. n., T.pseudallotopus sp. n., T.pseudanalis, sp. n., T.pseudovatulus sp. n., T.pseudovalipunctatus sp. n., T.pseudofulvicornis sp. n., T.pseudomanadensis sp. n., T.pseudosimulans sp. n., T.pumilus sp. n., T.rantepao sp. n., T.reticulatus sp. n., T.rhombiformis sp. n., T.rotundatus sp. n., T.rotundulus sp. n., T.rudis sp. n., T.rufipes sp. n., T.sampunensis sp. n., T.sampuragensis sp. n., T.satyrus sp. n., T.scabripes sp. n., T.scaphiformis sp. n., T.scitulus sp. n., T.selayarensis sp. n., T.serripes sp. n., T.seticnemis sp. n., T.silvicola sp. n., T.squalidulus sp. n., T.sulawesiensis sp. n., T.suturatus sp. n., T.tatorensis sp. n., T.tenuipes sp. n., T.tomohonensis sp. n., T.toraja sp. n., T.vicinus sp. n., T.viduus sp. n., T.volcanorum sp. n., T.wangiwangiensis sp. n., T.watsoni sp. n., and T.yoda sp. n.

Project description:Mitochondrial genomes of twelve species of Trigonopterus weevils are presented, ten of them complete. We describe their gene order and molecular features and test their potential for reconstructing the phylogeny of this hyperdiverse genus comprising > 1,000 species. The complete mitochondrial genomes examined herein ranged from 16,501 bp to 21,007 bp in length, with an average AT content of 64.2% to 69.7%. Composition frequencies and skews were generally lower across species for atp6, cox1-3, and cob genes, while atp8 and genes coded on the minus strand showed much higher divergence at both nucleotide and amino acid levels. Most variation within genes was found at the codon level with high variation at third codon sites across species, and with lesser degree at the coding strand level. Two large non-coding regions were found, CR1 (between rrnS and trnI genes) and CR2 (between trnI and trnQ), but both with large variability in length; this peculiar structure of the non-coding region may be a derived character of Curculionoidea. The nad1 and cob genes exhibited an unusually high interspecific length variation of up to 24 bp near the 3' end. This pattern was probably caused by a single evolutionary event since both genes are only separated by trnS2 and length variation is extremely rare in mitochondrial protein coding genes. We inferred phylogenetic trees using protein coding gene sequences implementing both maximum likelihood and Bayesian approaches, each for both nucleotide and amino acid sequences. While some clades could be retrieved from all reconstructions with high confidence, there were also a number of differences and relatively low support for some basal nodes. The best partition scheme of the 13 protein coding sequences obtained by IQTREE suggested that phylogenetic signal is more accurate by splitting sequence variation at the codon site level as well as coding strand, rather than at the gene level. This result corroborated the different patterns found in Trigonopterus regarding to A+T frequencies and AT and GC skews that also greatly diverge at the codon site and coding strand levels.

Project description:BackgroundUsing syntactic and semantic conventions of the taxonomic concept approach (Franz et al. 2015), we describe three newly recognized fossil broad-nosed weevils (Coleoptera: Curculionidae: Entiminae) preserved in Early Miocene amber (ca. 20.4-16.0 mya) from the Dominican Republic: Scelianoma compactasp. n. sec. Franz & Zhang (2017) (henceforth abbreviated as [FZ2017]), Tropirhinus palpebratussp. n. [FZ2017], and Diaprepes anticussp. n. [FZ2017]. The taxonomic assignment of the amber inclusions is grounded in a preceding phylogenetic analysis by Franz (2012). As many as 88 of the 143 therein identified characters were coded for the fossils, whose traits are largely congruent with those present in extant congeners while also differing in ways that justify their new nomenclatural and taxonomic status.New informationWe present detailed images, descriptions, and phylogenetically informed diagnoses for the three new species-level entities, along with logically consistent Region Connection Calculus (RCC-5) alignments of the amended genus-level classifications for Scelianoma Franz and Girón 2009 [FZ2017], Tropirhinus Schoenherr 1823 [FZ2017], and Diaprepes Schoenherr 1823 [FZ2017] - in relation to 2-4 preceding classifications published in 1982-2012. The description of Scelianoma compacta [FZ2017] from Hispaniola is indicative of a more widespread historical range of Scelianoma [FZ2017] than reflected in the extant, southwestern Puerto Rican Scelianoma elydimorpha Franz and Girón 2009 sec. Franz and Girón (2009). The presence of Diaprepes anticus [FZ2017] in Hispaniola during the Early Miocene suggests an eastward directed process of island colonization and likely speciation of members of Diaprepes [FZ2017], given that most extant relatives occur throughout the Lesser Antilles. The herein presented data will facilitate more reliable reconstructions of historical biographic processes thought to have played a prominent role in the diversification of the West Indian and Neotropical mainland broad-nosed weevil lineages.
