Hello, For this specimen, I first thought of a Helina, especially Helina impuncta, but then I was finally tempted, perhaps wrongly, by Mydaea urbana.

Mydaea sp. have setulae on radial node dorsally & ventrally, H. impuncta has 1-3 ac bristles presutural. What do you think of H. depuncta?

H. depuncta does indeed seem to fit well. |

Thank you again for suggesting H. depuncta. I discussed it further on insecte.org, and a few doubts were raised about some of the characters: almost bare eyes, yellow base of antennae, aristal hairs, tibial chaetotaxy, and also the point about infuscated cross-veins / 3 postsutural dc that you mentioned in another thread. Do you still think H. depuncta is the best fit here, despite these uncertainties? Many thanks in advance. |

H. depuncta was only meant to be a possible alternative to H. impuncta - not the best fit and the 4 post dc clearly contradict depuncta. But there are many Helinae with similar characters and to get closer we would need more details like aristal hairs, all katepisternals... Helina seems to be correct, but for species level we'd need a distinguished expert's opinion. Greetings, Eric |
