Description of two new species in the genus Glyphodes Guene from Indonesia (Lepidoptera: Crambidae, Spilomelinae).

Two new species of Glyphodes Guene, 1854 from Indonesia are proposed as new to science, namely G. nurfitriae sp. nov. and G. ahsanae sp. nov. The total number of recorded Glyphodes for Indonesia is 48 at present. Images of adults and genitalia are provided for both new species.

A new endemic clove tree pest of Cryptophasa Lewin, from Sangihe Island, Indonesia (Lepidoptera: Xyloryctidae).

A novel endemic pest of clove tree, Cryptophasa warouwi sp. nov., has been discovered on Sangihe Island. This new species can be distinguished from its closest relative species, C. watungi Sutrisno & Suwito, 2015 which is found in North Sulawesi, by its dark brown straw-coloured wings in both males and females. The most distinctive diagnostic characters of this new species are observed in its genitalia structure: a bent-downward uncus with a strongly sclerotized finger-shaped apex, a bent phallus gradually widened towards coecum, and a double, membranous corpus bursae branching off at mid-ductus corpus bursae of female genitalia. Additionally, DNA barcodes revealed this new species to be embedded among Australian Cryptophasa species despite having fasciculated male antennae that have been considered diagnostic of the genus Paralecta. This suggests that the male antennae may not be a reliable character for separating Cryptophasa from Paralecta. A more comprehensive study including all Cryptophasa and Paralecta will be required to elucidate the definition of each genus. Images depicting both adults and genitalia are provided for this newly recognized species.

DNA barcoding data release for the Phoridae (Insecta, Diptera) of the Halimun-Salak National Park (Java, Indonesia).

Launched in 2015, the large-scale initiative Indonesian Biodiversity Discovery and Information System (IndoBioSys) is a multidisciplinary German-Indonesian collaboration with the main goal of establishing a standardised framework for species discovery and all associated steps. One aspect of the project includes the application of DNA barcoding for species identification and biodiversity assessments. In this framework, we conducted a large-scale assessment of the insect fauna of the Mount Halimun-Salak National Park which is one of the largest tropical rain-forest ecosystems left in West Java. In this study, we present the results of processing 5,034 specimens of Phoridae (scuttle flies) via DNA barcoding. Despite limited sequencing success, we obtained more than 500 clusters using different algorithms (RESL, ASAP, SpeciesIdentifier). Moreover, Chao statistics indicated that we drastically undersampled all trap sites, implying that the true diversity of Phoridae is, in fact, much higher. With this data release, we hope to shed some light on the hidden diversity of this megadiverse group of flies.

The genus Agrioglypta Meyrick (Lepidoptera: Crambidae, Spilomelinae) from Indonesia with descriptions of three new species.

Inventory studies on the genus Agrioglypta Meyrick, 1932 have been conducted in Java, Sulawesi, and Papua during 2007-2011. This study also aims to explore the diversity of Agrioglypta in Indonesia, and the possible apomorphic characteristics, especially genitalic characters, that support the monophyly of the genus. Three new species were discovered, A. hastantiae sp. nov., A. ubaidillahi sp. nov., and A. halimunensis sp. nov., for a total of nine species of the genus recorded in Indonesia. Images of adults and genitalia are provided for all new species.

Twenty-eight new species of Trigonopterus Fauvel (Coleoptera, Curculionidae) from Central Sulawesi.

Here we present 28 new species of Trigonopterus from Central Sulawesi, mostly from Mt Dako and Mt Pompangeo: Trigonopterusacutus sp. nov., T.ancora sp. nov., T.arcanus sp. nov., T.corona sp. nov., T.dakoensis sp. nov., T.daun sp. nov., T.ewok sp. nov., T.gundala sp. nov., T.hoppla sp. nov., T.kakimerah sp. nov., T.katopasensis sp. nov., T.matakensis sp. nov., T.moduai sp. nov., T.mons sp. nov., T.paramoduai sp. nov. T.pomberimbensis sp. nov., T.pompangeensis sp. nov., T.puspoi sp. nov., T.rosichoni sp. nov., T.rubidus sp. nov., T.sarinoi sp. nov., T.sutrisnoi sp. nov., T.tanah sp. nov., T.tejokusumoi sp. nov., T.toboliensis sp. nov., T.tolitoliensis sp. nov., T.tounaensis sp. nov., T.unyil sp. nov. This fills important areas of distribution and brings the number of Trigonopterus species recorded from Sulawesi to 132.

Integrative ecological and molecular analysis indicate high diversity and strict elevational separation of canopy beetles in tropical mountain forests.

Tropical mountain forests contribute disproportionately to terrestrial biodiversity but little is known about insect diversity in the canopy and how it is distributed between tree species. We sampled tree-specific arthropod communities from 28 trees by canopy fogging and analysed beetle communities which were first morphotyped and then identified by their DNA barcodes. Our results show that communities from forests at 1100 and 1700 m a.s.l. are almost completely distinct. Diversity was much lower in the upper forest while community structure changed from many rare, less abundant species to communities with a pronounced dominance structure. We also found significantly higher beta-diversity between trees at the lower than higher elevation forest where community similarity was high. Comparisons on tree species found at both elevations reinforced these results. There was little species overlap between sites indicating limited elevational ranges. Furthermore, we exploited the advantage of DNA barcodes to patterns of haplotype diversity in some of the commoner species. Our results support the advantage of fogging and DNA barcodes for community studies and underline the need for comprehensive research aimed at the preservation of these last remaining pristine forests.

Mitochondrial genomes of twelve species of hyperdiverse Trigonopterus weevils.

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.

Seven new species of Trigonopterus Fauvel (Coleoptera, Curculionidae) from the Tanimbar Archipelago.

Based on recent fieldwork, the hyperdiverse weevil genus Trigonopterus Fauvel is recorded for the first time from the Indonesian Tanimbar Archipelago, halfway between Australia and Western New Guinea. All seven species discovered on Tanimbar are new to science, and described here: Trigonopterus atuf sp. nov., T. kumbang sp. nov., T. laratensis sp. nov., T. porg sp. nov., T. selaruensis sp. nov., T. tanimbarensis sp. nov., and T. triradiatus sp. nov. The new species are authored by the taxonomists-in-charge, Raden Pramesa Narakusumo and Alexander Riedel. This fauna appears discordant and established by relatively recent dispersal from New Guinea and other Moluccan islands.

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

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.

All new species are authored by the taxonomist-in-charge, Alexander Riedel.

Taxonomy and Biogeography without frontiers - WhatsApp, Facebook and smartphone digital photography let citizen scientists in more remote localities step out of the dark.

BACKGROUND: Taxonomy and biogeography can benefit from citizen scientists. The use of social networking and open access cooperative publishing can easily connect naturalists even in more remote areas with in-country scientists and institutions, as well as those abroad. This enables taxonomic efforts without frontiers and at the same time adequate benefit sharing measures. NEW INFORMATION: We present new distribution and habitat data for diving beetles of Bali island, Indonesia, as a proof of concept. The species Hydaticus luczonicus Aubé, 1838 and Eretes griseus (Fabricius, 1781) are reported from Bali for the first time. The total number of Dytiscidae species known from Bali is now 34.
