It might be identified as [i]Demonax bimaculicollis[/i] (Schwarzer, 1925) distributed in Taiwan. For example, it corresponds fully to the first two photos placed under this name by Larry Bezark [url="https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wdetails.asp?id=47955&w=o"][red]here[/red][/url]. On the other hand, I noticed that the beetles collected in Taiwan and shown in the photos placed by Taiwanian traders [url="http://www.insect-fans.com/bbs/data/attachment/forum/month_1003/1003022243cfb623aa648ef1be.jpg"][red]here[/red][/url] and [url="http://beetle.spider.acsite.org/pic_cerambycidae/demonax_bimaculicollis_01.JPG"][red]here[/red][/url] look different, like also the third beetle in Larry’s page. Beside a peculiar pubescence pattern in pronotum also the shape of the pronotum looks different. It is stronger narrowed apically than towards the base, and this way it is widest in the hind third in beetles from Taiwan. And then I found the photo of the holotype, description and differential diagnosis of D. simillimus Gressitt,1939 [url="http://coldata.ioz.ac.cn/showTaxa.asp?cid=%7B65FC95D3-4812-4ED8-9A93-92A840B820E1%7D&cpid=%7B04E41A01-FC0D-443F-8E56-E2A6A88CDB4C%7D&crid=%7B2F5B0D6A-1133-4681-A1C0-C3FAA42CF5CA%7D"][red]here[/red][/url]. In particular, it is stated “Differs from [i]Demonax bimaculicollis[/i] (Schwarzer) in having the prothorax longer, less globular and granulose instead of reticulate, the elytra longer, with darker markings and a broader postmedian pale band, and the posterior legs longer.” May it be that my beetle and the first two shown by Larry are in fact [i]D. simillimus[/i]?
