From Collembola collections made from 12 localities of Thailand Callyntrura genus group was studied for identification. Nine new species in addition to two new records for Thailand were determined. They are as follows: Callyntrura (Callyntrura) alpina Lee and Rojanavongse n. sp., Callyntrura (C.) nigra Lee and Rojanavongse n. sp., Callyntrura (C.) capitata Lee and Rojanavongse n. sp., Callyntrura (Gunungphysa) distincta Lee and Rojanavongse n. sp., Callyntrura (G.) montana Kim and Rojanavongse n. sp., Callyntrura (Sultanaphysa) antennata Kim and Rojanavongse n. sp., Callyntrura (Kudatphysa) striatella Kim and Rojanavongse n. sp., Callyntrura (Japonphysa) oligosetosa Kim and Rojanavongse n. sp, Callyntrura (Murphysa) hirsuta Kim and Rojanavongse n. sp., Callyntrura (J.) semilineata mediopunctata Yosii, 1985 and Salina cingulata (Handschin, 1925). The present study, accordingly, adds 9 species up to existing record of 14, making the number of species of the genus Callyntrura 23 in total from Thailand.
