Trichodomedea hyperythra, new species 

 Figures n: 18-19 



Holotype female and two paratypes from Odontophorus hyperythrus Gould 

 collected in "Granada" (Colombia) (USNM). 



Diagnosis : The head is similar to that of leucolaemus but is proportionally 

 narrower at the temples. Cephalic index of frons and temples is 0.92 : 1 .30, 

 that of the female of leucolaemus is 0.96 : 1.30. All body measurements are 

 considerably less. The prothorax is smaller and the pterothorax is 

 narrower. The distal abdominal segment is smaller and differently 

 shaped, having lateral margins (anterior to claspers) strongly convex, 

 while in leucolaemus they are straight. The claspers are also smaller and 

 of a different shape (see fig. 19). 



Measurements are given in the tabulation above. 



Trichodomedea erythrops, new species 

 Figures ii: 20-21 



Holotype male from Odontophorus erythrops Gould collected in Ecuador 

 (USNM). 



Diagnosis: Head close to that of heferura, but the male genitalia are 

 entirely different. The single male available is in rather poor condition; 

 however, the always complicated male genitalia provide infallible char- 

 acters for specific separation. Cephalic index of frons and temples is 

 0.52 : 1.28. The measurements are strikingly different from those of 

 heterura. 



Measurements are as given in the tabulation below. 



T. erythrops cf T. peruviana ? 



Holotype male from Odontophorus speciosus Tschudi collected in Peru 

 (USNM). 



Diagnosis: One of the larger and very distinctive species. Head with 

 narrow frons and wide temples. Cephalic index of frons and temples 

 is 0.64 : 1.28. Carinae of head distinctive, those extending from sides
