410E87C7537BFF86FF2BFD99FA97FE32.taxon	biology_ecology	Biological note. Adults were mainly collected from damaged trees of Picrasma quassioides (Simaroubaceae; Nigaki in Japanese). Matoba (2008) collected 15 adults from a logged P. quassioides tree. Nakamura (2009) collected an adult from the underside of a leaf and Kuroda (2017) collected two adults by sweeping the tips of branches of living P. quassioides trees. The third author found a number of adults on the trunk of a damaged tree of P. quassioides in Nagano Prefecture. He observed agonistic behavior between males, mating behavior, and act of an individual making a hole in the bark of the trunk by using its rostrum (Figs 31 – 33). The second author found a number of adults on a stand dead tree of P. quassioides (Figs 34, 35). He also observed mating behavior and acts of several individuals making holes in the bark of a trunk of the tree.	en	Fujisawa, Yusuke, Yoshitake, Hiraku, Kojima, Hiroaki (2025): Weevils of the genus Neomecopus Hustache, 1921 (Curculionidae: Conoderinae: Mecopini), with description of a new species from the Ryukyus, Japan.
