Abstract: Two new species of the genus Glischrochilus Reitter, 1873, subgenus Librodor
Reitter, 1884: Glischrochilus (Librodor) pilula sp. nov. (Laos) and
Glischrochilus (Librodor) ruzickai sp. nov. (China: Yunnan, Sichuan; Myanmar)
are described, figured and compared with other species of the genus.
Glischrochilus egregius (Grouvelle, 1895) is formally synonymised with G.
egregius cyclops Jelínek, 1975, syn. nov. and G. egregius monticola Jelínek,
1975, syn. nov. – these two forms were established based on different body
colouration; however, the study of extensive material revealed that it is
variable independently of its geographic origin. The identity of Ips janthinus
Reitter, 1877 from Tasmania (previously included in Glischrochilus) is
discussed and the species is formally synonymised with Thallis ianthina
Erichson, 1842 (Erotylidae). New country records from China, India, Laos,
Thailand and Vietnam, or new Chinese provincial records are provided for
14 species. A world checklist of the genus Glischrochilus is appended.
