Trachysphyrus imperator remains known only from the holotype, 
obtained in the highlands of northwest Peru. Its closest relatives 
are T. imperialis and T. pehai from Neantarctic and Patagonian 
south Argentina and Chile. 
7. Trachysphyrus escomeli (Brethes) 
Cryptus Escomeli Brethes, (1918) 1919. Rev. Chilena Hist. Nat. 22: 124. Lectotype 
9 (labeled by Porter): Peru, Arequipa (Buenos Aires). 
The only known specimen of T. escomeli is the lectotype, which I 
examined in December 1964 at the Museo Nacional in Buenos 
Aires, Argentina. 
Arequipa, the Peruvian type locality for this species, is situated in 
a vast fertile valley of the Coastal Desert at 2800 m altitude near the 
main Andean cordillera. Repeated fieldwork from 1975-1982 in 
nearby north Chile and at Arequipa itself has failed to discovered 
additional specimens of T. escomeli. 
As previously mentioned, this species shares some features with 
T. agalma Porter and T. aglaus Porter but does not seem closely 
related to any other Trachysphyrus. 
8. Trachysphyrus cleonis Viereck 
(Fig. 7, 9) 
Trachysphyrus cleonis Viereck, 1913. Proc. U.S. Natl. Mus. 44: 470. Type Q: Peru, 
Cuzco, 1 1,500 ft (Washington). 
My redescription of T. cleonis (Porter 1967: 312-14) was based on 
70 females and 69 males from the central and western Andes of 
southern Peru. Most of this material came from Cuzco and other 
high inland localities, but several specimens were reported from 
Oroya, Acolla, and Jauja at elevations approaching 4000 m just 
above the Coastal Desert on the west Andean slopes. 
Western populations of T. cleonis have the body metallic blue and 
the legs blackish. Central Peruvian specimens are purple with 
orange legs. Such geographic variation suggests past or present dis- 
continuities in the species’ distribution, as perhaps determined by 
Pleistocene to recent climatic instability. 
Most of my records for T. cleonis span the spring and summer 
months (September to March). I have not collected the species dur- 
ing June and July fieldwork in Peru between 1974 and 1982. Long- 
term phaenologic analysis probably will confirm that other sympatric
