Otiotkops walckenaeri MacLeay, 1839, Ann. & Mag. Nat. Hist., 1839, 2: 12, 
pi. 2, fig. 5. Holotype female from Cuba probably in the British Museum 
(Nat. Hist.). Walckenaer, 1841; Simon, 1887, 1893; Petrunkevitch, 1911; 
Bryant, 1940; Roewer, 1942; Bonnet, 1958. 
This species remained known only from the female until Miss 
Bryant very briefly described the male in 1940. Because this descrip- 
tion is so brief I have thought it worth while to add some details 
and a figure to aid in identification of the species. Total length 4.49 
mm. Carapace 2.1 1 mm long; 1.43 mm wide; .91 mm tall. Essential 
features of the palp shown in Figure 12; embolic spine bifurcated 
distally. Eyes: viewed from above, posterior row procurved, anterior 
row gently recurved; viewed from in front, anterior row slightly 
procurved, measured by centers; posterior row strongly procurved. 
Ratio of eyes AME : ALE : PME : PLE = 14 : 10.5 : 14 : 9. 
AME circular, all others oval to some degree and with some irregu- 
larities. AME separated from one another by slightly more than 
their radius; from ALE by about their radius. PME white and 
shining; obliquely placed and hardly separated from one another; 
separated from PLE by about 1.2 times their diameter. Lateral 
eyes separated by about one sixth of the long axis of PLE. Central 
ocular quadrangle wider in front than behind in ratio of about 15 : 
13; longer than wide in front in ratio of about 7 : 6. Clypeus 
convex; deeply grooved near ventral margin; height equal to a little 
less than twice the diameter of AME. Legs: 4123 in order of length; 
tibial index of first leg 14, of fourth leg 10; first femora the most 
robust and slightly longer than the fourth; anterior patellae by far 
the longest; fourth tibiae and metatarsi the longest of the four. 
Sternum with a pair of minute cusps at lateral angle of termination be- 
tween fourth coxae which are separated by 1.3 times their width. Claw 
tufts throughout ; claws two. Anterior tarsi club-shaped ; anterior 
tibiae with iridescent, prolateral scopulae or brush; anterior metatarsi 
with thick scopulae along the whole prolateral surface ; anterior tarsi 
with similar scopulae on basal third of prolateral surface. Abdomen 
with a ventral scutum extending from genital groove to pedicel and 
dorsally to cover base of abdomen to dorsal anterior border. Two 
spinnerets as usual ; nearly surrounded by a chitinous ring incomplete 
dorsally in region of anal tubercle. Tracheal spiracle apparently 
indicated by a pair of minute chitinous plates a short distance anterior 
to base of spinnerets. 
Fetnale. Trichobothria have been regarded as absent in this family
