As part of ongoing investigations on anthidiine bees, the type of Anthidium albitarse Friese was found to be conspecific with one of the two species of the small resin bees Hypanthidioides subgenus Michanthidium. The new combination, Hypanthidioides (Michanthidium) albitarsis, is the oldest name, resulting in Gnathanthidium sakagamii Urban as a new junior synonym. The previously unknown male of the second species, Hypanthidioides ferrugineus, is described and figured, including the genitalic structure and associated sterna. Males and females of Hypanthidioides ferrugineus have been collected from flowers of Cuphea sp. (Lythraceae).
作为对黄斑蜂的持续研究的一部分，发现黄斑蜂（Anthidium albitarse Friese）的模式种与小型树脂蜂Hypanthidioides亚属Michanthidium的两个物种之一同种。新组合Hypanthidioides (Michanthidium) albitarsis是最早的名称，这使得坂上黄斑蜂（Gnathanthidium sakagamii Urban）成为一个新的次异名。描述并图示了第二种锈色Hypanthidioides ferrugineus此前未知的雄性，包括生殖器结构和相关腹板。锈色Hypanthidioides ferrugineus的雄性和雌性均采自萼距花属（Cuphea sp.，千屈菜科）植物的花朵。
