From Sabah, Trus Madi, 9 mm.
Not Serixia? Or Entelopes or Parentelopes?
Please. |

Quand-même pas mal moins allongé que bien d'autres Serixia?

Merci Jean-Philippe et Xavier.
L'épine de l'apex semble moins prononcé que le type de Malaysie occidentale. Mais c'est un tout petit détail. J'inscris S. apicalis. |

Pascoe described 2 species in the paper: S. (s.str.) apicalis and S. modesta. S. apicalis is the genotype.
Per Pascoe, S. apicalis (Malacca) with "a bright luteus spot on the apex" of the elytra. I don't observe that in the photo. The apex of the elytra appears different due to light reflections of the shiny tomentum, I believe.
S. modesta (Borneo) smaller (4 lines = about 8mm ) similar but without apical spot.. Hmmmm maybe closer, but would be nice to see holotype.
With about 28 species (2/3rds described by Breuning) of the nominate subgenus recorded from Borneo, there is no choice but to just say "Serixia sp." |

yes, that's why I wrote " Serixia cf. apicalis " |

Thank you Dan and Xavier. Yes, I will stand with Serixia sp.
I also posted two more Serixia species from Sumatra. They are smaller than the ones from Sabah.
And they both have this bright luteus spot on the apex, especially the blond one.
The one from Jumbi has a darker tip of elytra probably because of the reflexion.? |

These specimens from BMNH are S. aurulenta. The one in the upper left that is only partly visible is the type.
The BMNH specimens may all be slightly faded, (or perhaps another poor photograph) and in that case they are a much better match to Gontran's beasties.

Thank you Dan.
None of pictures is good enough to go further. ID on picture has a limit, and we reach it. |

| Of course it could match but I agree we can't go further with pictures only, especially for these taxa. Thanks for your efforts. I appreciate. |

Borneo: Serixia cf. apicalis
