Two new species
To date, 3 subgenera of the genus
In the current work, two new species of the subgenus
The specimens were collected by chopping deadwood in forests. They were killed with ethyl acetate and dried. The morphological examinations were carried out with a stereomicroscope. For an examination of the male or female genitalia, the last three abdominal segments were detached from the body after softening in hot water. For clearing, it was boiled for 5 minutes in 5% solution of potassium hydroxide, and then, washed in distilled water. Morphological figures were prepared using a Nikon SMZ1500 stereomicroscope. All measurements are given in millimetres. The habitus photos were taken with a Leica M205A camera. Holotypes and paratypes are deposited in the Museum of Hebei University (MHU), Hebei, P. R. China.
Morphological terminology predominantly follows
The measurements of proportions are abbreviated as follows:
bl/bw – body length/width ratio;
pl/pw – pronotum length/width ratio.
