Distribution
Dryoxylon onoharaense
(Murayama, 1934) (Fig.
1
) is an Eastern Palearctic species belonging to the
Xyleborini
tribe distributed in China, Japan and South Korea (
Smith et al. 2020
). Recently, it has been introduced to North America, where it is now widely established (
Gomez et al. 2018
). The independent collection of eight females in two geographically separated areas in NE Italy indicates the successful establishment of the species. These represent the first records of
D. onoharaense
in the Western Palearctic and a new genus and species to Europe (Fig.
2
).
Notes
Dryoxylon onoharaense
specimens were collected in the Padua Province (Veneto Region, Italy) by trapping performed in the Euganean hills area using homemade transparent panel traps baited with ethanol. Traps were hung approximately 1 m above the ground, a height where ambrosia beetles are generally abundant (
Miller et al. 2019
,
Marchioro et al. 2020b
). The three
D. onoharaense
specimens found from the Belluno Province (Veneto Region, Italy) were collected at Vette Feltrine State Nature Reserve using flight intercept window traps baited with 75% ethanol that were hung from Norway spruce trees in a mixed forest severely damaged by the Vaia storm in 2018.
Hosts
The species is polyphagous on broadleaves, recorded from
Acer saccharum
Marshall (
Sapindaceae
) (
Bright and Rabaglia 1999
),
Liriodendron tulipifera
L. (
Magnoliaceae
) (
Atkinson 2022
),
Populus deltoides
W.Bartram ex Marshall (
Salicaceae
) (
Coyle et al. 2005
) and
Quercus
sp. (
Fagaceae
) (
Murayama 1934
); the host plants of this beetle species in Europe remain unknown. Little is known about the biology of
D. onoharaense
and it remains unclear if it is a xylomycetophagous species (
Bright and Rabaglia 1999
,
Bateman et al. 2015
); the findings reported in
Coyle et al. (2005)
suggest myelophagy as a possible feeding habit. The species is included in the European and Mediterranean Plant Protection Organization (EPPO) database (EPPO Code: DRYXON); to date, no direct proof exists regarding any economic or ecological impact of this species.
Identification remarks
The identification of the species was confirmed morphologically (using the keys provided in both
Gomez et al. (2018)
and
Smith et al. (2020)
), as well as through the DNA barcode (GenBank ref: ON533858) (99.48% of identity on BOLD System).
