Using Breuning 1958 key, if I follow "elytra dark brown throughout", this keys to [i]Serixia paradoxa fuscipennis[/i]. But the front face protrusion is unlike that of the red form of the S. paradoxa that I have (which is described as "very strong triangular tooth directed obliquely outwards"). The front face is also quite flat otherwise, unlike that of S.paradoxa. If I follow "elytra partially red" (which can be seen in the picture above), this leads to Serixia fumosa peraffinis. Makihara has a similar species identified as S.fumosa too. However, both Pascoe and Breuning description said that the third joint is considerably shorter than the scape. So I was quite confused.[?] [img]/public/imgforum/loongfah/2016617164810_Chestnut 120108 longhorn Serixia black 01 cropped.jpg[/img][br][size=1] 313.08 KB[/size=1] [/quote]    Insert an Image File Check here to include your profile signature.
