''Callobius severus'' is a species of spider found in parts of North America. Individuals reach roughly 19 mm (3/4") in size, with males typically appearing smaller than females. Cephalothorax and legs are reddish to dark brown and the abdomen is dark to light grey with fine hairs, often appearing with large, bilaterally mirrored paler spots. Males feature large, extended palps with prominent projections. It is a nesting woodland species commonly seen in the Pacific Northwest, and one of the most commonly found and widespread spiders in populated areas of Washington state.〔Vetter, Rick and Antonelli, Art : (How to identify (or misidentify) the hobo spider ). Washington State University.〕 It can often be found in households and other man-made structures with thin funnel webs, so long as the niche has not yet been filled by another organism. The species poses no threat to humans or pets,〔Akre, Roger D. and Catts, Paul E. : (EB1548: Spiders ). Washington State University.〕 though like other ''Callobius'' species, the bite is painful. ==References==
