 as long as the sixth tergite.

 at base 0.88, at apex 0.50 mm. wide, and but 0.16 mm. high basally; 

 dark testaceous yellow with apical third blackish brown.

This small Chilean species is undoubtedly related to costalimai, 

 differing from all known species by the mesonotum of which only 

 the median third is dusted, the lateral thirds being bare and shining. 



Male: Length of body 3.6 mm.; wing 3.6 mm. long and 1.5 mm. 

 broad, 2.4 times as long as broad. 



Head testaceous yellow, 0.68 mm. long, 1.05 mm. wide, and 0.88 

 mm. high. Frons at vertex 0.50 mm., at anterior margin 0.41 mm. 

 broad, and on median line 0.48 mm. long. Oral margin of mesofacial 

 plate raised and prominent. Inferior margin of cerebral plate slightly 

 raised. Postpedicel broad-oval, 0.20 mm. long and 0.15 mm. wide, 

 only 1.25 times as long as wide. Seta bare, shining black, except 

 for the testaceous yellow basal fourth, 2.4 times as long as postped- 

 icel. Eyes in profile 0.68 mm. high and 0.39 mm. wide, approximately 

 1.7 times as high as wide. Genae below eyes 0.13, inferior region of 

 postcranium in profile 0.30 mm. wide (that is to say, unusually wide). 



Cephalic bristles brownish yellow; the usual garniture present, the 

 distribution and the relation in length is normal as in salesopolitana. 

 The distinct genal bristle in this species is also darker in color than 

 the other bristles. 



Thorax with scuteUum 1.5 mm. long and 1.1 mm. wide, testaceous 

 yellow; it is characteristic of this species that only median third of 

 mesonotum is covered with whitish pruinosity, lateral thirds and pos- 

 terior margin on both sides and behind this broad vittalike pruinose 

 area bare and shining. Mesonotum, except for the narrow hind mar- 

 gin, covered as usual with evenly distributed short appressed pale 

 yellow hairs. Hind region of mesonotum marked with the usual 

 lateral black spots, each between prescutellar and upper postalar 

 bristles; behind (and beneath) wing base a pointlike small black dot.
