Dromites from the 3.5 Expanded Psionics Handbook is a psionic race "called bug-men by the ignorant".
Diopsids from the 3.5 Dragon Compendium is beetle-like race in the Underdark.
Insectare from Dragon Magazine are "part elven, part insectoid".
I prefer not to discuss the Khepri.
Xixchil from the AD&D MC9 Monstrous Compendium Spelljammer Appendix II are basically green Thri-Kreen with a penchant for body modification.
Chitines from 3.x Monsters of Faerûn are not exactly insectile, but rather spider-like.
Of course, this list is probably not complete. And "insect-like features" is a rather subjective standard, so I imagine for instance the Xephs could be considered to have "insect-like" eyes.
