Stichopogon barbistrellus f._9767
This species is distributed from Hungary to as far east as Mongolia and China. The most important distinguishing character is the yellowish brown mystax ("mustache", darker in males), which is white in the case of S. elegantulus, black and "bushy" on S. albofasciatus (the latter has entirely black legs). Stichopogon scaliger, males of which may have yellow-brown mystax, has a different abdominal pattern and lacks the relatively long, dark acrostichal setae on the mesonotum of S. barbistrellus.
(This specimen is relatively freshly emerged, slightly tenereal, therefore the reddish color of the tibiae is not very obvious.)
