Neosminthurus richardsi

Thanks to a recent upload of Scott Justis I have rechecked your pics of Neosminthurus. And concluded your specimen is not N. clavatus but richardsi, given the ratio of ant.4/ant.3 is about 1.25.
(In clavatus it is at least 1.35.)

Neosminthurus clavatus

I checked the pictures again. And this time more carefully. Neosminthurus is a genus close to Sminthurinus. It also has the 4th antennal segment not annulated. But the antennae are shorter.
The body of Neosminthurus is typically covered with strong, short, truncated setae.
So, not Sminthurinus maculosus but Neosminthurus clavatus.
Sorry, for the confusion caused...

Sminthurinus maculosus, possibly.

It appears as if the 4th antennal segment is not annulated. Therefore Sminthurinus. Given the dark mottled purplish body colour with slightly paler legs, it could be S. maculosus.

thanks again Frans

I made a species page -- it can be moved if necessary.
