越南标本图片参考
这图的鉴定者,有在研究绿天牛族
这号有疑问的澳门标本,保存在美国
近期从美国寄到了澳门大学
以下图片由澳门大学的李斯辰拍摄
澳门天牛里的判断:
Remarks.Easton (1993) reported this species as “Chelidonium sinense(Hope)”but it seems most likely that the main species involved in his observations was actually C. argentatum and not Polyzonus sinensis, given the laterally expanded metatibia and short tarsal segments exhibited by the typical specimen illustrated in his work (Easton 1993: 47).
综上,目前我能给的结论是:维持Easton (1993)的原判,是中华多带天牛Polyzonus sinensis (Hope, 1842)。我们文章里的结论,是根据文献图片得出的,误判为之前鉴定为绿天牛Chelidonium argentatum,我们错了。

澳门报道里面错误的推论的相关讨论:
我的讨论:
Perissinotto, Renzo的回复:Now, regarding Polyzonus sinensis, we have reported it as occurring in Macau (Taipa Island) in our 2021 ZooKey census paper, with illustrations and recent records. So, in my view the issue of the identification of Easton's specimen is of relative minor importance. It is very clear from the photos you have sent that the specimen illustrated in there is indeed P. sinensis. Unfortunately, when I analysed the Easton Collection at the University of Macao, there were no specimens of either P. sinensis or Chelidonium argentatum in any of the cabinets I was given access to at the time. So, I don't really know where this specimen comes from - was it outside Macau and now it has been returned, or what else? What we looked at was the old and poor quality photo included in Easton 1993 (see attached PDF copy), and then considering that we had observed many specimens of C. argentatum but hardly any of P. sinensis during our 3-year survey, we became convinced that Easton may have actually confused the two species in his account. In his paper of 1992 (see attached PDF copy), he specifically mentions having observed/collected the species at least on two different occasions (28 May and 30 May). In summary, I don't think we need to do anything at this stage, as we reported that "it seems most likely that the main species involved in his observations was actually C. argentatum and not Polyzonus sinensis". The word "main", unequivocally does not exclude P. sinensis. Perhaps what can be done at the next opportunity, when this species is mentioned in a relevant context, is to write a little note specifying that a specimen of P. sinensis from the Easton's Collection has now been traced and confirms that this species was indeed correctly reported in his publications.
图片11月22日就发来了,我想着尽快回复的,但是做到一半,我被打断去处理其他事情了,然后我就把这件事情给忘记了。抱歉!
同时被忘记的,是答应11月19日回复的一个稿子,被我忘得一干二净,今天才匆忙处理。
怎么办呢?忘事的频率越来越高。
最不能战胜的,是时间这把无情之剑。
