All known species records are assigned to provinces when possible. The provincial records are given in a separate Table. The highest numbers of species were found for Sichuan (67), Yünnan (62), Taiwan (56), and Fujian (52). The male genitalia of the species in the Ilybius apicalis group are illustrated.

An account is given of the 20 Helophorus species known or suspected to occur in China, with additional notes on the 43 non-Chinese species known from the surrounding area. One new subgenus, Thaumhelophorus subgen.n., is erected, and four new species are described: H. (Thaumhelophorus) inexpectatus sp.n. [Assam], H. (s.str.) jaechi sp.n. [China], H. (Rhopalhelophorus) kazakhstanicus sp.n. [Kazakhstan], and H. (R.) laferi sp.n. [Primorye]. Helophorus (R.) matsumurai Nakane is redescribed and its aedeagophore figured. Helophorus lamicola Zaitzev is designated as the type species of the subgenus Lihelophorus Zaitzev, and lectotypes are designated for H. lamicola and H. ser Zaitzev. Helophorus mukawaensis Watanabe, 1983 is synonymized with Helophorus sibiricus Motschulsky, 1860. It is noted that the Helophorus fauna becomes attenuated in the Far East, especially in the Primorye and Japan, and it is suggested that the 20 species so far listed from China may represent about two thirds of the actual fauna.

Three new species, all from China (Yünnan), are described: Hydrocassis baoshanensis sp.n., H. metasternalis sp.n. and H. schillhammeri sp.n. A neotype is designated for Hydrocyclus imperialis Knisch. The four species of the genus Ametor are arranged in three species groups. Lectotypes are designated for Ametor rudesculptus Semenov and Hydrocyclus rugosus Knisch. The following new combinations and new synonymies are established: Hydrocassis scapha d'Orchymont (= H. vietnamica Sat“ syn.n.), Ametor scabrosus (Horn) (= Ametor lucifer (Shatrovskiy) syn.n. et comb.n.), A. rudesculptus Semenov (= A. oberthuri d'Orchymont syn.n., = A. wittmeri Sat“ syn.n.), Ametor rugosus (Knisch) (= Ametor rufrenus (d'Orchymont) syn.n. et comb.n.). The aedeagi of all species are illustrated. A key to the species groups and species of the two genera is provided.

Caldara, R. & O'Brien, C.W.: Curculionidae: Aquatic weevils of China (Coleoptera), p.389
Seventy-one aquatic or semiaquatic species of Curculionidae belonging to 18 genera are considered: 28 are known from China, whereas the others have not been collected yet in China, but their present known distribution and their collection in adjacent territories make their presence in China very probable. Among the described species already collected in China are: 2 Erirhinus Schönherr, 1 Icaris Tournier, 1 Grypus Germar, 4 Echinocnemus Schönherr, 2 Tanysphyrus Schönherr, 10 Bagous Germar, 4 Neophytobius Wagner, 1 Pelenomus Thomson, 1 Rhinoncomimus Wagner, and 2 Rhinoncus Schönherr. We report general information on habits, immatures and collecting techniques of the aquatic weevils, a key to the genera, with photos and line illustrations useful for their recognition, and a list of species with the main references, synonymies, general range and detailed records for China, biology where available and remarks where necessary. A list of host plant genera is included for most of the herein treated weevil genera. Also, after the examination of the types we established that Hydronomus phytonomoides Voss, 1953 must be transferred to the genus Echinocnemus, and that Lissorhoptrus pseudooryzophilus Guan, Huang & Lu, 1992 must be synonymized with Lissorhoptrus oryzophilus Kuschel, 1952.
