In 1837 C. L. Koch* following Sundevall 18327, placed D. mira- 
bilis in the genus Ocyale, (now in Pisaura) and it is therefore 
evident that D. fimbriatus of Clerck® is the type of Dolo- 
medes as indicated by Thorell. 
Generic characters. Cephalothorax slightly longer than broad, 
high and convex in the eye region, somewhat flattened on the disk, 
and provided with a definite dorsal groove and less distinctly marked 
radical furrows; posterior declivity broad and steep. yes in two 
rows, (pl. 21, fig. 4) those of the posterior larger, usually about 
equal in size (when unequal, the posterior median slightly smaller 
and closer to each other than to the lateral) and equidistant. An- 
terior row usually slightly recurved with the median larger than 
lateral (rarely with anterior row straight and eyes subequal in size). 
Median ocular area a little wider posteriorly than long and much 
narrower in front than behind. Clypeus as wide or wider than the 
height of the median ocular area. Lower margin of the furrow of 
the chelicera with four teeth (pl. 21, fig. 3). Legs strongly 
developed, usually 4-1-2-3, third shortest, the others almost equal 
in length; tibiae and metatarsi of first and second legs below, armed 
with 2-2-2-2 and 2-2-1 spines, respectively. Anterior segment of 
the superior lorum of the pedicle notched behind to receive a pro- 
jection of the posterior segment (pl. 21, fig. 5).
