Comment : The above specimens represent the first records since the original description, which is based on a male from the Daba Shan at the border between Shaanxi and Chongqing and one from the Jiajin Shan in West Sichuan ( ASSING 2006c ). As was to be expected, the previously unknown female primary and secondary sexual characters are similar to those of other species of the O. hauseri subgroup.
