7E671150B116FFCEFF1EFD23BE288906.taxon	diagnosis	Diagnosis. This new species resembles S. abdominalis (Sasakawa & Tamu) in wing pattern and general appearance of the male terminalia, but it differs from the latter in the subtriangular terminal flagellomere in the male antennae, and gonocoxites having 18 – 20 black strong spines on each posteromesal lobiform part in the male terminalia. In S. abdominalis, the terminal flagellomere is suboval in the male antennae, and the gonocoxites have 23 – 25 short spines on each posteromesal lobiform part in the male terminalia.	en	Qi, Lei, Huang, Junhao, Wu, Hong, Wang, Qingyun (2022): Two new species of Setostylus Matile, 1990 (Diptera: Keroplatidae) from China.
