The Dacini fruit flies of Borneo: an annotated checklist with 89 species including three new to science (Tephritidae, Dacinae)

Our work adds 46 species to the 43 previously known from Borneo, bringing the total for the island to 89. Three new species are described: Bactrocera (Bactrocera) melanobivittata Doorenweerd, sp. nov., Dacus (Mellesis) danumensis Doorenweerd, sp. nov., and Zeugodacus (Zeugodacus) cataracta Doorenweerd, sp. nov.

Adult Bactrocera fruit fly ID

Adult Bactrocera fruit fly ID provides identification support for 800 species of fruit flies in the economically important genus Bactrocera and its closely allied genera in the tribe Dacini. This website includes fact sheets and a Lucid multi-entry key with color illustrations and photos.

Hawaiian caterpillar patrols spiderwebs camouflaged in insect prey’s body parts

We report a species in which caterpillars are carnivorous inhabitants of spider’s webs, feeding on the arthropods that they find there.

CCS‐Consensuser: A Haplotype‐Aware Consensus Generator for PacBio Amplicon Sequences

We present CCSconsensuser, an end-to-end pipeline that generates consensus sequences from amplicon sequencing using high-fidelity reads produced by PacBio circular consensus sequencing (CCS).

Towards a better future for DNA barcoding: Evaluating monophyly‐ and distance‐based species identification using COI gene fragments of Dacini fruit flies

We generated a COI reference library for 265 species of Dacini containing 5601 sequences that span most of the COI gene using circular consensus sequencing. We compared distance metrics versus monophyly assessments for species identification and although we found a ‘soft’ barcode gap around 2% pairwise distance, the exceptions to this rule dictate that a monophyly assessment is the only reliable method for species identification.

Genomic data reveal new species and the limits of mtDNA barcode diagnostics to contain a global pest species complex (Diptera: Tephritidae: Dacinae)

We present restriction site-associated DNA sequencing (RAD-seq) genomic data for 2,292 specimens, which unequivocally supports the delimitation of two new species, here described as Bactrocera borneoensis sp. n. Doorenweerd & San Jose and B. incognita sp. n. Doorenweerd & San Jose.

Interspecific gene flow obscures phylogenetic relationships in an important insect pest species complex

Under concatenation, both datasets suggest identical species relationships with mostly high statistical support. However, multispecies coalescent and multispecies network approaches suggest markedly different hypotheses and detected significant gene flow.

Genomics reveals widespread hybridization across insects with ramifications for species boundaries and invasive species

As the amount of genomic data for nonmodel taxa grows, it is increasingly clear that gene flow across species barriers in insects is much more common than previously thought.

Five new species of Hawaiian endemic fancy case caterpillars from a recently established forest reserve on Maui (Cosmopterigidae: Hyposmocoma)

We here describe five new species of Hawaiian fancy case caterpillars, Hyposmocoma Butler (Lepidoptera: Cosmopterigidae), from East Maui

Inadequate molecular identification protocols for invasive pests threaten biosecurity

Molecular markers are crucial to identify new pest invasions before they can become established but current methods are often inadequate.
