AR 0.63-0.95; R with 3-13 setae, R1 with 0-6 setae, R4+5 with 0-13 setae; squama with 4-6 setae; inferior volsella trianguler at middle; virga consisting of very weak field of about 20 minute spinules; crista dorsalis low, HR 1.68-1.91, HV 2.53.

Specimens examined.

China: Hunan Province: 1 ♂, Chenzhou City, Yizhang County, Mang Mountain, 25°24'N, 113°18'E, 22.vii.2004, Chuncai Yan, sweep net.

Remarks.

Sæther and Sublette (1983) described the male imago, pupa and larva from the U.S.A. The Chinese specimens mainly agree with the adult description of Sæther and Sublette (1983). According to Sæther and Sublette (1983), there are not significant differences between Pseudorthocladius (Pseudorthocladius) uniserratus and Pseudorthocladius (Pseudorthocladius) curtistylus in the male hypopygium, but as we can see in the figures of Pseudorthocladius (Pseudorthocladius) uniserratus , the gonostylus is expanded at about distal while Pseudorthocladius (Pseudorthocladius) curtistylus is narrowed; the inferior volsella is triangler at middle part. The Chinese specimens agree with Pseudorthocladius (Pseudorthocladius) uniserratus more.

Distribution.

Oriental China (Hunan Province); U.S.A.; Canada.
