8 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 120 
I am designating as lectotype a syntypic male in the collection of the 
Museum of Comparative Zoology which agrees with Ulmer’s figures. 
The figures of the species were prepared from the lectotype. 
Rhyacophylax brasilianus Ulmer 
FIGURES 2a,b 
Rhyacophylax brasilanus Ulmer, 1905a, p. 108; 1907b, p. 176; 1913, pp. 391, 392, 
407.—Banks, 1913a, p. 88.—Tomaszewski, 1961, p. 4.—Fischer, 1963, pp. 
135, 136. 
Lectotype, male: “S. Catarina Liiderwaldt,” “Type,” “St. zg. 
1905, p. 108, N. 91,” “Inst. Zool. P.A.N. Warszawa Syntypus Nr. 
1758,” “Rhyacophylax brasilianus Ulm. Typus!” ‘Lectotype Rhya- 
cophylax brasilianus Ulmer By Flint.” In Warsaw. 
The eye of the male of this species is about one-half as wide as the 
distance between the eyes. The forewings, which are badly damaged, 
appear to be pale on their basal half, dark especially toward the costal 
margin, a narrow pale band at the cord, followed by a dark apex. 
The male genitalia are also damaged; the tip of the aedeagus is lacking. 
The figures of the male were made from the lectotype. 
Synoestropsis obliqua Ulmer 
FIGURE 2h; PLATE 2A 
Synoestropsis obliqua Ulmer, 1905a, pp. 45-47; 1907b, p. 158; 1907c, pp. 28, 29; 
1913, pp. 392, 407.—Tomaszewski, 1961, p. 5.—Fischer, 1963, p. 210. 
Lectotype, male: ‘Rio Grande do Sul,” “Type,” “St. Z. 1905. 
p. 46 N. 27,” “Inst. Zool. P.A.N. Warszawa Syntypus Nr. 1760,” 
“Synoestropsis obliqua Ulmer Typus!”’ ‘Lectotype Synoestropsis 
obliqua Ulmer By Flint.”” In Warsaw. 
The drawings of the genitalia and the photograph of the wings were 
made from the lectotype. 
Synoestropsis pedicillata Ulmer 
Figure 27, PLATE 2B 
Synoestropsis pedicillata Ulmer, 1905a, pp. 43-45; 1907b, p. 158; 1907c, pp. 26, 27; 
1913, pp. 392, 407.—Jorgensen, 1919, p. 396.—Tomaszewski, 1961, p. 5.— 
Fischer, 1963, p. 210. 
Lectotype, male: “S. Catarina Liiderwaldt,” ‘Type,’ “Inst. Zool. 
P.A.N. Warszawa Syntypus Nr. 1761,” ‘Lectotype Synoestropsis 
pedicillata Ulmer By Flint.” In Warsaw. 
The photograph of the wings and the drawings of the genitalia were 
made from the lectotype. The type series varies somewhat in the ex- 
tent of dark spots around the crossveins.
