Helicopsyche lutea (Hagen). — Ulmer, 1907c, p. 94; 1913, p. 411 .— Betten, 1934, 

 p. 418. 



The lectotype, designated by Ross, is a female. I have a male 

 from Santo Domingo that agrees with the type in size and coloration. 

 It appears to be the same as the one recently described by Kingsolver 

 from Cuba as H. comosa; however, until a series of this species 

 containing both males and females is available, I hesitate to establish 

 the synonymy. 



Helicopsyche mexicana Banks 



Helicopsyche mexicana Banks, 1901, p. 368. — Ulmer, 1907b, p. 94; 1913, p. 411. — 

 Betten, 1934, p. 418.— Ross, 1944, p. 289.— Denning, 1964, p. 132. 



Both Ross (1944) and Denning (1964) have figured the male 

 genitalia of this species. It was described originally from a single 

 male from Mexico. 



Helicopsyche muelleri Banks 



Helicopsyche mulleri [sic] Banks, 1920, p. 348. — Marlier, 1964, p. 15. 

 Helicopsyche turbida Navas, 1923, p. 200. — Schmid, 1949, p. 419. — Marlier, 1964, 



p. 15. [New synonymy.] 

 Helicopsyche angelae Marlier, 1964, p. 9. [New synonymy.] 



Lectotype, male: "Santa Catharina Brazil no. 18 F. Miiller," 

 "Type 10906," "Helicopsyche mulleri Bks. type." 



It is with some hesitation that I synonymize these three species. 

 The male genitalia of the type of mulleri and the figures of the geni- 

 talia of the types of turbida (Schmid, 1949) and angelae (Marlier, 1964) 

 are identical. Both of the latter species, however, are stated to lack 

 the process from the sixth sternum, which is clearly present in muelleri. 

 Perhaps the spines are broken off in the types of turbida and angelae, 

 or the presence or absence of the process may vary from one part 

 of the range to another. 



Helicopsyche peruana Banks 



Helicopsyche peruana Banks, 1920, p. 349. — Marlier, 1964, p. 15. 

 Helicopsyche woytkowskii Ross, 1956b, p. 398. [New synonymy.] 



The figures (Ross, 1956b) of the type of woytkowskii are very 

 similar to the holotype, male, of peruana. The only difference is 

 that peruana has four small seta-bearing teeth along the dorsal 

 margin that are not shown in Ross's figure. In spite of this, I believe 

 the two are synonymous.
