'''Chawa-vitabu''' (kutoka [[Kiing.]]: [[w:PsocopteraPsocodea|booklice]]) au '''chawa-vumbi''' (kutoka [[Kiholanzi]]: [[:nl:Stofuizen|stofluis]]) ni [[wadudu]] wadogo (mm 1-2) wa [[familia (biolojia)|familia]] [[Liposcelididae]] na [[Trogiidae]] katika [[oda]] [[PsocopteraPsocodea]] ambao hawana [[bawa|mabawa]]. Takriban [[spishi]] zote zinaishi katika majengo ambamo hula maada za wanga, k.m. ambo katika [[kitabu|vitabu]] (asili ya jina).

Wadudu hawa wana umbo wa [[nzi-gome]] bila mabawa. Wana nasaba karibu na [[chawa]] vidusia ambao siku hizi hufikiriwa kuwa oda ndogo katika [[nusuoda]] [[Troctomorpha]].
