Size
Males ~ 2-3 mm; Females ~ 3-4 mm (body length).
Identification
Adults can be distinguished from other species of Hyptiotes by specific features of the epigynum or palp. Given the known distribution of the four species in the genus, it might be reasonable to include geographic location as a diagnostic clue (for example, only gertschi appears to be known from the Northwest - please see genus page and references)?
Range
All across Canada and along the Pacific Coast from southern Alaska to southern California. Some records for the inland Western states and appears to overlap with H. cavatus in New England and New York.
Habitat
"Webs of individuals of H. gertschi may be abundant among the dead interior branches near the bottom of pine trees. Additional habitats, in the western part of the range, are cliff faces, ravines and bridges" (1).
