relationships. This species shows great superficial resemblance 
to C. violaceipennis but may be distinguished by the features given in 
the preceding diagnosis and emphasized in the key. The distinctive 
ovipositor tip of C. aricae suggests that its host preferences may 
differ from those of other sympatric Violaceipennis group species. 
field notes. The Malaise Trap used at Chapiquina, a Puna 
locality more than 3000 m above Arica, was placed across a small 
stream bordered by dense, tall bunch grass and, more distantly, by 
alfalfa fields and Eucalyptus plantations. 
specific name. Aricae is a latinized genitive singular derived

(Fig. 13, 14). 
female. Color: antenna black with a white band above on fla- 
gellomeres 3-10; head and mesosoma black; a white line briefly on 
facial orbit opposite antennal socket, a short white line on orbit at 
top of eye, and a white line on about median 0.4 of hind orbit; fore 
and mid legs black with faint reddish brown staining, especially 
apicad on femora; hind leg with coxa, trochanter, trochantellus, and 
most of femur red; weakly blackish on apical 0.8 of hind femur and 
uniformly black on tibia and tarsus; gaster red; wings blackish with 
metallic blue and purple reflections. 
Length of fore wing: 9.4 mm. Flagellum: long, slender, cylindric; 
1st flagellomere 6.0 as long as deep at apex. Front: moderately 
excavated. Clypeus: gently and almost symmetrically convex in pro- 
file; apical margin gently convex. Malar space: 0.8 as long as basal 
width of mandible. Temple: 0.4 as long as eye in dorsal view; 
strongly receding and gently convex. Fore tibia: stout but not at all 
inflated. Wing venation: radial cell 3.6 as long as wide. Propodeum: 
spiracle 2.0 as long as wide; propodeal surface as grossly but less 
reticulately or irregularly wrinkled than in violaceipennis. First 
gastric tergite: postpetiole 1.5 as wide at apex as long from spiracle 
to apex. Second gastric tergite: strongly shining with faint but pal- 
pable micro-reticulation or shagreening (more polished than in T. 
violaceipennis ); punctures very sparse and faint, their setae much 
more widely spaced than the lengths of the interspaces. Ovipositor: 
sheathed portion 0.5 as long as fore wing; straight, rather slender, 
strongly compressed; nodus very low, weakly defined, with a small
