as several times their diameter over apical 0.5 of mesoscutum. 
Mesopleuron: swollen area along prepectal carina above opposite 
speculum often largely smooth and polished with only sparse and 
tiny punctures. Wing venation: ramellus sometimes absent. Propo- 
deum: basal and apical faces varying from weakly to (often) sharply 
discrete; cristae moderately small but well projecting, subligulate to 
bluntly cuneate. First gastric tergite: postpetiole 1.5- 1.7 as wide 
apically as long from spiracle to apex; surface of postpetiole some- 
times almost without micro-reticulation. Second gastric tergite: 
often highly polished and with faint to sometimes almost impercept- 
ible micro-shagreening. Ovipositor: sheathed portion 0.7-0. 8 as 
long as fore wing; tip 0.20-0.24 as high at notch as long from notch 
to apex. 
Male. Color: white flagellar annulus sometimes on as few as 
segments 1 1-17 or as many as 2-18, variable in all populations but 
averaging most extensive in Chilean specimens; hind orbit with or 
without a white line; legs beyond trochantelli often extensively 
orange. 
Length of fore wing: 8.8-14.0 mm. First flagellomere: 2.6-3. 5 as 
long as deep at apex. Malar space: 0.8- 1.0 as long as basal width of 
mandible. Temple: 0.9- 1.0 as long as eye in dorsal view. Mesoscu- 
tum: punctures average denser than in female. Propodeum: cristae 
subligulate to subcuneate and strongly projecting; apical trans- 
carina scarcely palpable between cristae. First gastric tergite: 1. 0-1. 3 
as wide apically as long from spiracle to apex. Second gastric ter- 
gite: micro-reticulation varying from faintly detectable to almost 
absent.

Relationships. Trachysphyrus metallicus and T. carrascoi occur 
sympatrically and seem to be very intimately related. They may be
