SYNONYMY 
My first redescription of T. metallicus (Porter 1967: 277-79) was 
taken from 1 female and 2 males collected at Huarez and Matu- 
cana, Peru. Since then, 12 additional females and 23 more males 
have accrued, as a result of collecting at Matucana in Peru and in 
the Tarapaca Province of Chile. This material shows that T. metal- 
licus demonstrates conspicuous variation (mainly chromatic) within 
each local population and also along a north to south cline. The 
southernmost populations in this cline (Tarapaca, Chile) originally 
were described as a separate species, T. phaedimus Porter (1967: 
281-83), which now is synonymized with T. metallicus. 
The following description redefines T. metallicus with special ref- 
erence to its individual and polytypic variability. 
Female. Color: white flagellar band present on segments 2 or 
3-8 or 9; with or without white line on hind orbit; metallic colora- 
tion of scape, head, mesosoma, coxae, trochanters, and gaster vary- 
ing from deep blue with extensive purplish reflections to mostly 
bright purple with prominent to inconspicuous blue reflections; legs 
beyond trochanters varying from black with more or less subdued 
metallic reflections through mostly deep to bright orange (duller on 
tarsi). 
Length of fore wing: 10.0-15.6 mm. First flagellomere: 3. 9-4. 4 as 
long as deep at apex. Malar space: 1. 1-1.3 as long as basal width of 
mandible. Temple: 0.7-0. 8 as long as eye in dorsal view; its punc- 
tures and setae conspicuous but variably dense. Mesoscutum: punc- 
tures, especially in Chilean specimens, often separated by as much
