EPEIROMULONA HAMATA, new species 



Male (pi. 46, figs. 23, 25, 26).— Palpus pale orange-yellow. Head, 

 base of antenna, patagium, tegula, pronotum, and mesonotum white. 

 A black spot in middle of thorax and another on base of tegula (usu- 

 ally covered by patagium). Metanotum and thorax underneath pale 

 orange-yellow (or sometimes whitish yellow). Legs pale orange- 

 yellow (sometimes whitish yellow) and marked with black as in E. 

 hiloba^ except that apex of first femur is yellow, not black. Abdomen 

 pale orange-yellow, slightly whitish at base above. Antenna beyond 

 base black with a long white streak just before apex. Forewings and 

 hindwings above and below very similar to E. phelina and hardly 

 separable from E. hiloba. Apical spot on hindwing variable, some- 

 times greatly reduced or absent and sometimes enlarged. 

 Length of forewing 6.5-8 mm. 



Male genitalia as illustrated (pi. 42, figs. 3, 3a, 3b; pi. 45, figs. 

 13-17). This species divides into three subspecies on the basis of ap- 

 parently constant differences in the harpes (see descriptions, pp. 

 462-464). 



Female (pi- 46, figs. 24, 27).— Habitus like that of the male. 

 Length of forewing 7.2-8.2 mm. 



Female genitalia as illustrated (pi. 44, figs. 9, 10). On the basis of 

 the female genitalia there is a fourth subspecies (see description, p. 

 465). 



Distribution. — Trinidad, northern South America and Brazil. 

 Com'parative rertiarhs. — In addition to the great differences in the 

 genitalia this species differs from E. hiloha in lacking the black on 

 the femur of foreleg and in having the legs yellow with black bands 

 instead of white with black bands. It is hardly distinguishable from 

 E. lephina and E. phelina except in the genitalia. However, the 

 black bars in middle and base of costa on forewing above are usually 

 thicker and more round or subquadrate than in 'phelina or hiloha. 



Suhspeciation. — As stated above this species divides into four sub- 

 species on the basis of the male and female genitalia. These sub- 

 species appear to be geographically isolated. They do not appear to 

 differ in color and habitus. When more material becomes available 

 for study so that the extent of individual variation can be worked 

 out it is possible that these subspecies will be elevated to specific rank.
