The abdominal pattern and length of stalk suggest to me a male of Graphogaster. Moreover, i think i see a hairlike third IA'bristle'. Jorge can easily check this hypothesis: prosternum hairy -> Graphogaster prosternum bare -> Rondania |

I used a small hand loupe and it seems bare the prosternum. I will try to take photos in this zone. |

Hmm, check very carefully ... it is very hard to see

Incredibly small - very tiny black hairs, often around the edge and can be just 1 hair  and you are looking at the smallest piece of chitin between and infront of the front legs in the centre - almost under the 'chin'.

i know where is it. But my doubt resides only in the lenght of the possible hairs.  ok.. I must seek carefully for any very small ~"hair". |

Yeah, they can be very small but should be clearly visible at about 40x magnification.

Not clearly to see... really 40x magnification is needed.

I will confirm this week the ID. I will have access to a stereomicroscope.. so I can see better the prosternum. |

OK, not as long as I suspected. Erikas might be right. Still, hairs on prosternum are decisive. These are very long and obvious in Graphogaster Theo |
