Both of them are females. The blue one is Scatopyrodes beltii. But I have no idea what the green one is. The green one has thicker antennae. The body shape is different. Maybe it is a female Scatopyrodes iris? Thanks! Attachments:

Greetings,
This looks to me like Scatopyrodes trichostethus (Bates), although I've never seen a female of S. iris. The locality seems to fit trichostethus better than iris, but the known ranges of many tropical species are incomplete.
Can you post an image of this female next to the female of trichostethus you posted earlier, to see how they compare?
Cheers!

Hi Bandrow! Here's the picture. As shown in the picture, the green one has much shorter antenna than the red one. The upper body shape is different. They look like they are unrelated. Attachments:

Remember, the Mallaspini can be quite variable. It matches my specimens of Scatopyrodes trichostethus for the female. It's simply using the keys and not being so damned critical all the time.

Small details should be observed carefully too.
Maybe you're right. This can be Scatopyrodes trichostethus.
However, I wanted to make sure.
Cheers

Hi Joon,
I agree with you that the two females are likely not conspecific. The shape of the pronotum is different; the relative length of the antennae are different; the smaller species seems to have a more pubescent scutellum; and the elytra of the larger species appear to be more rugose while those of the smaller species seem to be much smoother, especially apically.
I'm pretty sure the larger species is Scatopyrodes trichostethus, but I'm not so sure I was correct in giving you that name for the smaller species earlier - it appears to be something different now that I see them side-by-side, but I'm not sure what. ID'ing specimens from images is always tricky - but better to not have a name on something, than to haphazardly slap a wrong name on it.
Cheers!
