smooth and highly polished, scarcely shagreened, with scattered tiny 
punctures that emit long, mostly non-overlapping setae (which 
become longer and overlap apicad). Second gastric tergite : smooth 
and highly polished, sometimes with slight shagreening or micro- 
reticulation, and with numerous but remotely spaced tiny punctures 
that emit rather sparse setae which, nonetheless, mostly attain or a 
little surpass the length of their interspaces. 
Type Material. Holotype $: CHILE, Tarapaca Province, 
Belen, 3170 m, 18-19- VII-1976, C. Porter, C. Calmbacher, H. Var- 
gas. Paratypes: 3 2 with same data as holotype, 1 CHILE, 
Tarapaca Province, Socoroma, 3000 m, 20-VI-1979, C. Porter. 
Holotype in Florida State Collection of Arthropods. Paratypes in 
Collection of Charles C. Porter. 
Relationships. This high Andean species seems closely related 
to Trachysphyrus agalma Porter and T. aglaus Porter. It is best 
distinguished from the sympatric T. agalma by its sparse but very 
long and overlapping 2nd gastric setae (setae short and not overlap- 
ping in T. agalma). From the Peruvian T. aglaus, it differs in having 
the flagellum white banded, the temple conspicuously but not shag- 
gily setose, and the areolet comparatively symmetric with dorsally 
convergent intercubit.i. 
Field Notes. Specimens of T. aegla were obtained in the same 
type of West Andean Puna habitats already described for T. carras- 
coi, T. metallicus, and T. agalma. 
Specific Name. From the Greek noun aegla, “lustre, splendor, 
glory”.

(Fig. 10) 
Trachysphyrus aglaus Porter, 1967. Mem. Amer. Ent. Inst. 10 : 285-7. Type^: Peru, 
Pachacayo, 28-III- 19 1 3, C. H. T. Townsend (Washington). No additional' T. 
aglaus have accumulated since my original description. 
This species inhabits the Andes of west-central Peru. Among 
congeners of the Coastal Desert and contiguous highlands, it most 
resembles T. agalma and T. aegla.
