Well: Derolus.
It will be not easy, since Pic described several species that Plavilstshikov considered as synonyms (without checking the types). |

| It seems to be Derolus angustatus Pic, 1925, even if it could also correspond to Derolus coomani Pic, 1925 (a synonym of the previous, according to Plavilstshikov). |

| D'après les types, c'est Derolus coomani Pic, 1925... absolument pas synonyme de D. angustatus... comme il prétendait Plavilstshikov, sans même connaître les types. |

| Effectivement. Une synonymie avec angustatus n'est pas vraiment... une bonne idée... |
