Dendrolasma is a genus of harvestmen in the family Nemastomatidae with two described species (as of 2023).

[1][2] Both species are found in the western coast of North America.

[1][3][4][5] An overview of their taxonomy was provided by Schönhofer (2013).

In the past, additional species were included but have since been placed in Asiolasma or Cladolasma.

The appropriate gender agreement was originally overlooked by Banks when describing "D. mirabilis", but the suffix was subsequently amended to the neuter "mirabile" by Martens (1978), and adopted by later authors.
