There are two Exocentrus, very small.
I'm still not sure that they are different species. For all the diversity of representatives of this genus, I do not see that this design is frequent.
But I can not determine, of course.
male, 3,2 mm, S Vietnam, Bin` Fyok prov. |

And female there. ~3,5 mm, with the same origin, but from another window-trap. Pronotum much wider than in male and erect setae on the elytra are much thinner and more numerous.. |

Yes, it should belong to the subgenus Camptomyne Pascoe, 1864.
Here you can download the whole Breuning's monograph... but probably, further species have been described. |

| By using Breuning's keys, I'd say Exocentrus (Camptomyme) multiguttulatus Pic, 1927... just described from Vietnam! |

Yes, for my part, too much like multiguttatus.
But I have serious doubts remain as male and female of the same species. Thanks for you help! |

I agree with you: multiguttulatus is the second specimen, which is characterised by the "pronotum fortement transverse". Moreover, its elytral pattern perfectly corresponds to the description of this species.
I do not think that the pronotal shape is a sexual difference: this is a typical characteristic, for example, of the European E. lusitanus. Moreover, it seems to me that the pronotal puncturing is different enough. Accordingly, the differences in the elytral puncturing and pattern are not casual.
You should check whether further species of Camptomyne have been described from Laos or Vietnam after 1958 (searching by region in Lamiaires du Monde) or (better) through the Zoological Record, since it might be a new species. |

Well, Thanks!
According to "Lamiaires du mond", Breuning described from Laos (after 1958) many species: 3 in 1963, 2 - in 1965, 2 - in 1968, and another sp. in 1969 (the origin is not specified, it is necessary to look the article).
It seems to me highly probable, that any rufuloides or rufulescens it can appear a needed species
microspinicollis Breun., 1963
rondoni Breun.,1963
rufolateralis Breun.,1963
rufulescens Breun.,1965
rufuloides Breun.,1965
semiglaber Breun.,1968
triplagiatipennis Breun.,1968
and nigrofasciatipennis Breun.,1969 - not clearly whence occurs
Unfortunately, I do not have those articles. |

Yep... no one has been described from Vietnam.
Maybe I have the description of some of these Laotian species; however, they are all treated in Gressitt, Rondon & Breuning, 1970 - Cerambycid-beetles of Laos... it is necessary to read this volume. |

For me, by looking the type colour picture from Bishop Museum, it's probably Exocentrus (Camptomyne) rondoni Breuning, 1963 .
I add the original description by Breuning (1963).
if you can verify that the lower lobes of eyes are 4 x longer than the cheeks. |

Hi, Xavier,
For female this ratio of proportion approximately well, but for male - the cheeks some longer (around three times as shorter than lower lobes of eyes). |
