オァ ix new species of Trichoptera collected in Henan province are described and figured herein, they are Rhyacophila bivitta n. sp., Psychomyia dactylina n. sp., Dolophilodes lanceolata n. sp., Dolophilodes henanensis n. sp., Wormaldia bilamellata n. sp., Chimarra hamularis n. sp. The type specimens are kept in the Insect Collections of Nanjing Agricultural University.1. Rhyacophila bivitta, n. sp. (Rhyacophilidae), (Fig. 1) Body length: 9 mm, length of forewing: 9 mm. This species belongs to annulicornis Group (Schmid, 1970), but differs from the other members of the group in: (1).the vertical part of segment X simple, subtriangular in lateral view; (2).anal sclerites small, without root; (3).bases of parameres broad, and fused together, rest parts tubelike; (4).aedeagus trilobated, median lobe and the two lateral lobes equal in length. Holotype♂, Baiyun Mt. (1400 m), Songxian County, Henan Province, 15～18-VII-1996, collected by Wang Beixin. Paratype 1♂, Longyuwan forest farm (1000 m), Luanchuan County, Henan Province, 10～14-VII-1996, collected by Wang Beixin.2. Psychomyia dactylina, n. sp. (Psychomyiidae), (Fig. 2) Body length: 3 mm, length of forewing: 3.5 mm. The species is unique in: (1).base of superior appendages deeply excised toform a fingerlike process when viewed from behind; (2).inferior appendages on the dorsum of segment IX in lateral view; (3).aedeagus vertical, with a long process near its apex. Holotype♂, Paratype 1♂, Longyuwan forest farm (1000 m), Luanchuan County, Henan Province, 10～14-VII-1996, collected by Wang Beixin. 3. Dolophilodes lanceolata, n. sp. (Philopotamidae), (Fig.3) Body length: 6 mm, length of forewing: 5.5 mm. This species belongs to subgenus Kisaura and is similar to Dolophilodes pectinata Ross, but (1).the segment IX longer than its height, other than the length equals to the height in the latter when viewed laterally; (2).superior appendages claviform, other than triangular in the latter in lateral view; (3).basal joint of inferior appendage as long as distal one, other than 1.5 times as long as distal one in the latter; (4).both the forewing and hindwing without fork 1, by which it is distinguished from D. pectinata Ross. Holotype ♂, Longyuwan forest farm (1000 m), Luanchuan County, Henan Province, 10～14-VII-1996, collected by Wang Beixin. Paratypes: 16♂♂, same data as holotype; 4♂♂, Baiyun Mt. (1400 m), Songxian County, Henan Province, 15～18-VII-1996, collected by Wang Beixin.4. Dolophilodes henanensis, n. sp. (Philopotamidae), (Fig. 4) Body length: 6 mm, length of forewing: 6.5 mm. The species belongs to subgenus Dolophilodes and is similar to Dolophilodes burmanus Kimmins, but differs from the latter in: apex of segment X bulgy in lateral view; basal joint of inferior appendages obviously longer than distal one; phallobase saclike, with 4 spines. Holotype ♂, Paratype 1♂, Longyuwan forest farm (1000 m), Luanchuan County, Henan Province, 10～14-VII-1996, collected by Wang Beixin. 5. Wormaldia bilamellata, n. sp. (Philopotamidae), (Fig. 5) Body length: 5 mm, length of forewing: 5.5 mm. This species similar to Wormaldia chinensis (Ulmer), W. relicta (Martynov) and W. coreana Kumanski, but is distinguished from them by: (1).sternite VII with a long process reaching the posterior margin of sternite of segment VIII; (2).segment VIII with a short, triangular process; (3).posterior margins of segment IX not excised when viewed laterally, and upper and lower margins of the second joint of inferior appendages paralleled to each other. Holotype♂, Baiyun Mt. (1400 m), Songxian County, Henan Province, 15～18-VII-1996, collected by Wang Beixin.6. Chimarra hamularis, n. sp. (Philopotamidae), (Fig. 6) Body length: 5 mm, length of forewing: 6.5 mm. The species related to Chimarra tsudai Ross, but (1).segment IX obviously narrower than that of the latter in lateral view; (2).base of segmen
