          Abstract

          Seven species of Trigonalidae are recorded from Thailand, Lycogaster flavonigrata Chen, Achterberg, He & Xu, L. rufiventris (Magretti), Taeniogonalos fasciata (Strand), T. gestroi (Schulz), T. sauteri Bischoff, T. tricolor Chen, and an unidentified species. Four species, L. flavonigrata, T. cordada Chen, Achterberg, He & Xu, T. sauteri, and T. tricolor are newly recorded from Laos. Diagnoses, illustrations, and distribution records are given for the Thailand species. Trigonalys india Smith, sp. n., is described from southern India for specimens previously misidentified as T. rufiventris.

              A revision of the Chinese Trigonalyidae (Hymenoptera, Trigonalyoidea)

              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, Jezonogonalos 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 species 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. tricolorisoma sp. n., T. uncifera sp. n., Teranishia crenulata sp. n. and T. glabrata sp. n. Two species are reported new for China: Orthogonalys elongata Teranishi, 1929 and Nanogonalos flavocincta Teranishi, 1929 (renamed to Taeniogonalos subtruncata nom. 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 recognised 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 flavoscutellata Chen, 1949, P. rufofasciata Chen, 1949, and P. tricolor Chen, 1949.
