cases appear to be mixed. To avoid any future ambiguity, lecto- 
types are here designated for all species described from a series. 
The genitalia of the borrowed holotypes or lectotypes have been 
cleared and figures prepared from these preparations for species 
that have not been redescribed recently. In addition, photographs 
have been made of the wings of species in certain genera. The final 
drawings were prepared by Mr. André D. Pizzini from sketches made 
by the author. 
The work was made possible through the excellent cooperation of 
Dr. Cezary Tomaszewski, Zoological Museum of the University of 
Lodz, Lodz, Poland, who arranged for the loan of the types in the 
collection of the Institute of Zoology of the Polish Academy of 
Science in Warsaw and to Prof. Dr. Max Beier, Zoological Division 
of the Natural History Museum in Vienna, who lent the types in the 
collection of that museum. 
Rhyacophilidae 
Atopsyche longipennis (Ulmer) 
Psilochorema longipenne Ulmer, 1905a, pp. 110-112.—Tomaszewski, 1961, p. 4. 
Atopsyche longipennis (Ulmer) .—Ulmer, 1907b, p. 205; 1913, p. 884.—Ross, 1947, 
p. 128.—Ross and King, 1952, p. 202.—Fischer, 1960, p. 161. 
Atopsyche brasiliana Ulmer, 1909a, p. 73. [Lapsus for longipennis.] 
The collection from Warsaw contains two female syntypes. Appar- 
ently, Dr. Ulmer had retained a male syntype which should be 
designated lectotype. 
I have seen a series of males and females of the species from Nova 
Teutonia, Santa Catarina, Brazil. The genitalia of the female from 
this series are identical with those of the female syntypes. The 
males from the series are identical with the male type figured by 
Ross and King, giving additional evidence that the species is being 
correctly recognized.
