The genus
Jin X-X, Li C-D (2014) First record of
Specimens were collected from Xizang Province (Tibet) and Yunnan Province (Southwest China) using yellow pan traps.
Specimens were dissected and mounted dorsally or laterally in Canada balsam on slides following the method described by
Photographs were taken with a digital CCD camera attached to an Olympus BX51 compound microscope, and most measurements were made from slide-mounted specimens using an eye-piece reticle. Total body length excluding ovipositor was measured mostly with an eye-piece reticle from alcohol-preserved specimens before being dissected, but sometimes from slide-mounted specimens (meso- and metasoma, without head). All measurements are given in micrometers (μm).
