| Summary: | Chaetocladius binotatus (Lundström), comb. n. (Fig. 13) Orthocladius binotatus Lundström, 1915: 12.? Chaetocladius validus Brundin, 1956: 126. Type material. Hypopygium of holotype ɗ, RUSSIA: New Siberian Islands, upper reaches of Wosnessenje River, 4 vii 1903, A. W. Koltschak & P. W. Olenin. MALE IMAGO (n = 1) Hypopygium (Fig. 13). Anal point 94 m long, 19 m wide at apex, 30 m wide near base, free of microtrichia in apical half. Tergite IX with about 25 setae, including 5 on anal point; laterosternite IX with about 7 setae. Phallapodeme 165 m long, transverse sternapodeme 158 m long. Virga 94 m long, consisting of a cluster of about 7 spines. Gonocoxite 323 m long, gonostylus 143 m long, megaseta 19 m long. HR 2.26.
