Daxata is right!
According to the description, it is Daxata (Taxada) sumatrensis von Breuning, 1961. This species is the only Daxata characterised by a large entire prae-median black band.
According to Breuning (1963), this species has been known from a single specimen coming from Sumatra (Museum of Lausanne). |

Well, a new species from Borneo... it is not the first with such kind of distribution.
Breuning (1963) recorded from Borneo only Daxata (s. str.) camelus Pascoe, 1864, which is characterised by elytra with erected pubescence and two transversal black bands on the disc (here Pascoe's original picture).
Heffern also quoted in his catalogue of Bornean Cerambycidae D. (Taxada) ustulata Pascoe, 1866 and D. (Taxada) confusa Pascoe, 1869.
The former species has no transversal bands on the elytra but a longitudinal sub-humeral band, while you can find a picture of the latter in this paper (pag. 70, fig. 74, det. Gilmour). |

| Thank you for the links. So you suppose this is Daxata (Taxada) sumatrensis, just not included in the check list for Borneo, right? |

| Sure. I can send you Breuning's key and descriptions as attachment, if you need them. |

I have seen that in some web-sites such as this there is a beetle like yours called D. ustulata
On the contrary, the true ustulata is a very different species: this is the picture of Pascoe's original paper (1866, Proc. Zool. Soc. London, Pl. XXVII, Fig. 4).
Actually, I do not know whether the record of ustulata for Borneo is a correct date. |

| I agree, the species from Borneo does not look like ustulata; these may be D. sumatrensis, just not included in the list for Borneo. |
