This is a very common species. |

I have just posted a photo of the holotype of Polyphida clytoides Pascoe, 1869. It's not a good picture, but you can see the pattern on the elytra.
Here is another photo of a specimen in my collection which I believe is P. clytoides.
I don't have a picture of P. argenteofasciata Aurivillius, but I have specimens from Sabah which could be that species.

The specimen from Sabah, and the holotype of P. clytoides seem to be a good match to the specimen from Singapore, but would like other opinions, especially from Loongfah. |

Petr Viktora has just published a paper describing two new Polyphida species. There are some type pictures in this paper (but no P. argenteofasciata).
According to Petr, my specimen above is not a P.clytoides as its elytral apex does not have a sharp pointing angular spine.
According to the Sarawak Cerambycinae website (used to be at http://www.arbec.com.my/cerambycinae but seems to have moved):
Elytral apex with a sharp pointing angular spine; gena long; clypeus divided from frons by a A-shaped sulcus; antennal segment 3 twice as long as 4; frons with a median groove; antennae entirely blackish fuscous. - clytoides PASCOE, 1869
Elytra obscurely angulate at angle; gena very short; clypeus and frons not indistinctively separated; antennal segment 3 elongated, 3 X as long as 4; median groove on frons obscure; antennae fuscous, segment 7 & 8 testaceous (yellowish-brown). -argenteofasciata AURIVILLIUS, 1910
So it remains possible that the specimen above is a P.argenteofasciata.

Specimen uploaded by Dan looks like P. clytoides.
I do not know the type of P. argenteofasciata, since it is on loan for many years (probably in Holzschuh's home). |

Singapore, Polyphida argenteofasciata?
