The Japanese forms of Eumenidae are revised, and 54 species (77 forms in total) are recorded, and five forms are described as new to science.
Seasonality and vertical structure of light-attracted insect communities in a dipterocarp forest in Sarawak
Nocturnal flying insects were collected monthly for 13 months using ultra violet light-traps set at various vertical levels in a weakly-seasonal, tropical lowland dipterocarp forest in Sarawak, Malaysia to detect non-random, seasonal trends of insect abundance.
Within-tree distribution of nest sites and foraging areas of ants on canopy trees in a tropical rainforest in Borneo
The results suggest that spatial partitioning by ant assemblages on canopy trees in tropical rainforests is affected by microenvironmental heterogeneity generated by three-dimensional structures (e.g., trees, epiphytes, lianas, and aerial soils) in the crowns of canopy trees.
The Oriental species of the ant genus Probolomyrmex (Insecta: Hymenoptera: Formicidae: Proceratiinae)
This work aims to provide a ontological basis for the classification of Oriental Probolomyrmex species based on the worker as well as investigate the relationships between these species and each other.
Six-Year Population Fluctuation of the Giant Honey Bee Apis dorsata (Hymenoptera: Apidae) in a Tropical Lowland Dipterocarp Forest in Sarawak
The data suggest that the A. dorsata population increases rapidly in response to general flowering and that this is initiated by nonseasonal, long-distance migration.
Synopsis of Aenictus species groups and revision of the A. curra x and A. laeviceps groups in the eastern Oriental, Indo-Australian, and Australasian regions (Hymenoptera: Formicidae: Aenictinae)
Twelve species groups are established in the ant genus Aenictus of the eastern part of Oriental region, and Indo-Australian and Australasian regions, and the species of the Aenictus currax group and
Sorting specimen‐rich invertebrate samples with cost‐effective NGS barcodes: Validating a reverse workflow for specimen processing
This study demonstrates that an next‐generation sequencing (NGS) barcoding pipeline that allows for cost‐effective high‐throughput generation of short specimen‐specific barcodes and accelerates invertebrate species discovery, facilitates downstream taxonomic work, helps with building comprehensive barcode databases and yields precise abundance information.
Ant communities on small tropical islands: effects of island size and isolation are obscured by habitat disturbance and 'tramp' ant species
Human disturbance on islands in the Thousand Islands Archipelago promotes the introduction and/or establishment of tramp species, which affects the composition of insular ant communities, and expected biogeographical patterns of ant richness are masked.
