The genus Wixia was based by O.P. -Cambridge in 1882, 
on the species abdominalis known only from the female 
from the Trail collection from the Amazon. In 1889, he 
erected the genus Amamra in the Biol. Centrali- Ameri- 
cana, 1, p. 55, for five species from Central America. A 
few years later, in the second volume of the Biol., F.O.P.- 
Cambridge placed this genus as a synonym of Wixia but 
he gave no reason for so doing. 
Wixia serrallesi does not agree perfectly with the defi- 
nition of the genus as given bv F. O.P. -Cambridge. The 
eyes are the same in both male and female, with the a.m.e. 
the largest, the clypeus is less than a diameter of a.m.e., 
instead of very high, the abdominal tubercles are small in 
both male and female. Eventually, the genus Amamra 
may be revived, either as a distinct genus or a subgenus 
of Wixia , and serrallesi would be placed with it, rather 
than in the genus Wixia , which has large abdominal tuber- 
cles and the quadrangle of median eyes square. 
Wixia serrallesi is very near to Wixia clivosa (O.P.- 
Camb.) known from both male and female from Mexico 
and placed by O.P. -Cambridge in the genus Amamra.
