Indonesia: Seram Dimension = 13 mm. I'm not able to identify its tribe ? It looks like a Phoracanthini but antennae are not spined. The last segment of the maxillary palp is well developed. I saw the same species (female) from Borneo (West Kalimantan) on ebay. Your help is welcome for ID.
Thank you Andreas. I'm sure I saw a specimen of the same genus from Borneo on ebay, but unfortunately I haven't win the bid ! It was perhaps the same species or an other (new ?). We may have soon the answer ...
