ZooKeys 385: 1–207. doi: 10.3897/zookeys.385.6560 Abstract The Chinese fauna of the family Trigonalyidae Cresson, 1887, is revised, keyed and fully illustrated for the first time. Eight genera of this family (Bakeronymus Rohwer, 1922, Bareogonalos Schulz, 1907, Jezonog- onalos Tsuneki, 1991, re-instated, Lycogaster Shuckard, 1841, Orthogonalys Schulz, 1905, Pseudogonalos Schulz, 1906, Taeniogonalos Schulz, 1906 and Teranishia Tsuneki, 1991) are recorded from China. The genus Ischnogonalos Schulz, 1907, is synonymized with Taeniogonalos Schulz, 1906. In total 40 valid spe- cies are recognized. Twenty species are new for science: Jezonogonalos elliptifera sp. n., J. jiangliae sp. n., J. luteata sp. n., J. nigrata sp. n., Lycogaster angustula sp. n., L. flavonigrata sp. n., L. nigralva sp. n., Orthogonalys cheni sp. n., O. clypeata sp. n., O. robusta sp. n., Pseudogonalos angusta sp. n., Taeniogonalos bucarinata sp. n., T. cordata sp. n., T. geminata sp. n., T. sculpturata sp. n., T. triangulata sp. n., T. tricolori- soma sp. n., T. uncifera sp. n., Teranishia crenulata sp. n. and T. glabrata sp. n.

Seven new synonyms are proposed: Poecilogonalos yuasai Teranishi, 1938, and P. maga taiwana Tsuneki, 1991, of Taeniogonalos taihorina (Bischoff, 1914); Taiwanogonalos minima Tsuneki, 1991, and T. similis Tsuneki, 1991, of Taeniogonalos alticola (Tsuneki, 1991); P. intermedia Chen, 1949, and P. unifasciata Chen, 1949, of Taeniogonalos formosana (Bischoff, 1913).Six taxa are rec- ognised as valid species: Bakeronymus seidakka Yamane & Terayama, 1983, Jezonogonalos laeviceps (Tsuneki, 1991), J. satoi (Tsuneki, 1991), Taeniogonalos alticola (Tsuneki, 1991), T. flavoscutellata (Chen, 1949) and T. gestroi (Schulz, 1908). Five new combinations are made: Jezonogonalos laeviceps (Tsuneki, 1991), comb. n., J. satoi (Tsuneki, 1991), comb. n., Taeniogonalos flavoscutellata (Chen, 1949), comb. n., T. gestroi (Schulz, 1908), comb. n. and T. lachrymosa (Westwood, 1874), comb. n.. Lectotypes are designated for Lycogaster violaceipennis Chen, 1949, Poecilogonalos flavoscutellataChen, 1949, P. rufofasciata Chen, 1949, and P. tricolor Chen, 1949.
