Abstract: Objective To investigate the species distribution of midges in Cona county, Tibet Autonomous Region, China. Methods Midges were captured with light traps in cattle pens and residential areas in Cona county, followed by slide specimen preparation with phenol balsam. Results We described a male midge of Alluaudomyia desma Yu, 2005 found in Cona county. The identifying characteristics are:Eyes with interfacetal hairs. Wing with a dark spot in r-m cross-vein,and with a dark spot in distal portion of R2 cell. Genitalia ninthtergum apically with two angular process, adeagus with two digitate process in distal portion, parameres with rod-shaped, basal portiot with two hookted bend,and end with lateral curvature. The wing pattern of male All. desma is similar to that of All. longzhouensis Hao et Yu, 1991, but the latter male insect has distinct aedeagus and paramere appearances from male All. desma. The specimen is deposited in the Center for Disease Control and Prevention of Northern Theater Command (Shenyang, 110034). Conclusion The characteristics of the newly found male specimen, which are consistent with the original description of the female holotype specimen. Combined with morphological characteristics, collection location and time, it was identified as All. desma, which supplement important male information that was lacking in the original species, and provides a reference for the classification and identification of All. desma.
