Now I've found Suwa's 2002 paper http://eprints.li...09-127.pdf in which he retracts the identification of the German H. bavarica with the Japanese H rufitibia. It's probably irrelevant anyway. The paper makes little mention of colour, and you can't know anything without a good view of the genitalia, but one characteristic of the group is the shortness of the ad seta on t1 compared with the neighbouring setulae - not the case here, so probably H. linogrisea is correct.
