Type species. Gladicosa gulosa (Walckenaer) 
Etymology. The generic name is a combination of gladius 
(Latin for sword) referring to the unique sword-shaped embolus of 
the male palpus, and cosa derived from the generic name Lycosa. It 
is considered feminine. 
Diagnosis. Gladicosa may be distinguished from other lycosid 
genera by the following combination of characters: (1) the swordlike 
or bladelike form of the embolus (em) and its clockwise orientation 
in ventral view of the left palpus of the male (Fig. 33), (2) the modi- 
fication of the terminal apophysis (ta), which is also broadly flattened 
and parallels (and partly supports) the embolus (Figs. 33, 34), (3) the 
rectangular or wedge shape of the transverse piece (tp) of the scape 
of the epigynum, together with its white pearlescent appearance, in 
whole or part (Fig. 10) and (4) the dorsal color pattern illustrated in 
Figures 1-5 and described below. 
Description. Total length 7.8 to 18.8 mm. Carapace length 4.2 
to 8.3 mm; width 3. 1 to 6.4 mm. Carapace viewed dorsally, narrow- 
ing at level of PLE row, smoothly convex along lateral margins, 
with posterior margin concave; viewed laterally essentially the same 
height from eye region to posterior declivity (highest point is poste- 
rior cephalic region in front of dorsal groove with the carapace 
sloping very slightly anteriorly). Dorsal groove long and distinct. 
Dorsal color pattern with light uneven submarginal stripes and wide 
median light colored stripe, narrow between ALE, widening until 
just anterior to dorsal groove (where it is usually constricted), 
becoming wider again parallel to groove, and then narrowing as it
