Identification
Distinguished from similar Tipula by the distinctive male genitalia: eighth sternite with broad shallow incision filled with light bearing two crossing tufts of light yellow hairs, and sub-triangular chitinized plates on lateral margins. The specific pattern of yellow and brown striping on the , with seventh and eighth segments often almost entirely dark, provides additional diagnostic characters. The restricted geographic range (San Francisco and San Mateo counties only) is a strong indicator for identification.

More Details
Taxonomic history
First described by Rennie Wilbur Doane in 1908 in the journal Psyche. The name 'vestigipennis' refers to reduced or wing characteristics relative to body size, particularly notable in the relatively short wings of females.
Conservation status implications
Extremely restricted range (two counties only) suggests potential vulnerability to loss and urbanization in the San Francisco Bay Area, though no formal conservation assessment has been documented.
