The Punctidae is a family of small to minute land snails that are often under-represented in museum collections, with investigations hampered by small size and lack of material. Herein we describe four species of minute punctids (1.0-1.2 mm in shell width) from Tasmania, three of which extend into mainland Australia, using comparative shell morphology and phylogenetic analyses of mitochondrial (COI, 16S) and nuclear (ELAVI8) DNA. We introduce Paralaoma albina, Paralaoma corrugata, Paralaoma miniscula and Paralaoma monticunea, and demonstrate that they are genetically distinct and can also be separated on subtle but consistent shell characteristics, including tightness of coiling, shell height, umbilical width, shell colour, and rib strength and spacing. Paralaoma miniscula becomes Australia’s smallest punctid, with a shell width of only 1 mm.
