Borneo, Sabah.
Seemed to be a couple, but pronotum looks very different.
20 / 17 mm. |

| Yes. It is interesting. I have a pair also where there pronotums of the male and female are different, but not quite as distinct as your. I think they are the same species. I know of no other species in Sabah that it can be easily confused with. As you can see, every other feature of this pair is similar, aside for the length of the antennae. Noserius tibialis. Occurs in Borneo and Sumatra, perhaps more regions. |

Yes, very interesting indeed. The coloration of body and legs, ridges in elytra are similar, antennae are somewhat lighter in a male, but pronotum and side tubercles have very different shape. It looks like these features are variable. I have one more male with pronotum wider than in one in the photo, and a female with a narrower pronotum. Extreme forms happened unintentionally to this photo.
Noserius tibialis Pascoe, 1857. According to the Catalogue of Cerambycidae from Borneo, spread in Borneo, Sumatra, Java, SE Asia. |
