Abstract: Four new species of Laccobius Erichson, 1837 in the subgenus Glyp- tolaccobius Gentili, 1989 are described: L. guttalis sp. nov. (Nepal), L. hanka sp. nov. (India: Arunachal Pradesh), L. josefi sp. nov. (India: Arunachal Pradesh) and L. sipeki sp. nov. (India: Meghalaya). New records are provided for the following species of the subgenus Glyptolaccobius: L. egregius Gentili, 1995 (India: Ut- tarakhand), L. eliogentilii Hebauer, 2002 (Bhutan, India: Meghalaya), L. sharmai Gentili, 1995 (Nepal), and L. silvester Gentili, 2006 (India: Uttaranchal). Laccobius moriyai Kamite, Ogata & Hikida, 2007 is compared with the remaining species of the subgenus Glyptolaccobius and the male genitalia of L. pluvialis Gentili, 2006 are redrawn. An updated identification key of Glyptolaccobius species is provided, the male genitalia of all new and some additional species are illustrated and habitus photographs of L. guttalis sp. nov., L. moriyai, L. hanka sp. nov. and L. sipeki sp. nov. are provided. Differential diagnosis of the subgenus Glyptolac- cobius is modified to accommodate the newly described taxa.
