Potamyia chekiangensis (SCHMID) comb. n. (Fig. 20)

Cheumatopsyche chekiangensis SCHMID. 1965: 142-145 . Holotype, China, West Tien-mu-shan. 19 September 1932 (MAK, not examined) (1 paratype, same data, examined).

Potamyia parva TIAN & LI 1987: 128. Replacement name for Hydropsychodes chinensis MARTYNOV 1930 . Syn.n.

Antennae 1.5 times length of forewing. In forewing, crossveins Cul-Cu2 and M3+4-Cu1 touching. In hindwing veins M and Cu1 running parallel; fork 1 absent. Spur formula 244. This species is easily distinguished from all others in the genus by the loss of the hook formation on the tenth tergum. TIAN & LI (1987) transferred Hydropsychodes chinensis MARTYNOV (1930) to Potamyia without examining the type and proposed a replacement name because of the resultant homonymy with Potamyia chinensis ( ULMER,1915) . We have examined the holotype of H. chinensis MARTYNOV 1930 (in BMNH), and it clearly belongs in Cheumatopsyche .
