T. dewalquei is widely spread over South and Central America. 
Chapuis’ T. dejeant has been recognized as a junior synonym of 
dewalquei by Schedl (1960a); the same author (1963), has subse- 
quently used dejeani for Mexican specimens. Having seen specimens 
from South and Central America, I believe these species must be 
considered synonyms, as originally proposed by Schedl. 
In Central America, T. dewalquei (recorded always as dejeani ) 
is known from several localities in Mexico (Blandford, 1896; 
Schedl, 1933; 1940; 1952; 1960a; 1963), Guatemala and Nicaragua 
(Blandford, 1896), Costa Rica (Blandford, 1896; Schedl, 1933), 
and Panama (Blandford, 1896) ; as shown in fig. 9.

Genus Tesserocranulus Schedl, 1933. 
Very little is known about this genus. Only very few specimens 
from wide apart localities have been studied; both sexes are known 
only in T. nevermanni, type of the genus. It seems, however, basically 
South American in distribution, with at least one of the three 
species ( T. nevermanni Schedl) reaching into Central America. 
T. ftexibilis Schedl, known only from females, was recently re- 
described and illustrated (Reichardt, 1964a). Study of additional 
material, especially of males, may necessitate removal of this species 
from Tesserocranulus. The female, at least, has very peculiar anten- 
nal structure and head shape. T. ornatus Schedl, based on one female, 
from an unspecified locality in Brazil, is known only from the type.

T. nevermanni , previously known only from the two original 
localities, is now recorded from Bolivia. This record extends the 
range of the species far to the south, and may indicate that never-
