Tomoplagia stonei, new species 



Figures 90; 97,a,6; Plate 19, figure 1 



A large well-defined species of the pleuralis group with the same 

 general characters as all other Tomoplagia species but differing from 

 them in having small and shining brownish black insertion circlets on 

 the thorax at bases of the presutural, dorsocentral, supra-alar, postalar, 

 prescutellar, and scutellar bristles. It seems to be closely related 

 to arsinoe Hering (Colombia) and to punctata, new species (Argentina) . 



Male: Length 6.7 (7.3) mm.; wing 7.5 (8.1) mm. long and 3.1 

 (3.3) mm. wide, always longer than body and nearly 2.5 times as 

 long as wide. 



Head 1.09 (1.13) mm. long, 1.91 (2.07) mm. wide, and 1.77 (1.93) 

 mm. high, pale ochraceous yellow; frons homogeneously pale ochrace- 

 ous yellow, only genovertical and ocellar plates slightly grayish, 

 parafacial plate below eyes brownish yellow; ocelli transparent clear 

 yellow; frons at vertex 0.86 (0.88) and at anterior margin 0.56 (0.66) 

 mm. wide, and in median line 0.70 (0.85) mm. long, shorter than wide 

 at vertex; mesofacial plate impressed as in all other species; oral 

 margin raised and considerably prominent. Antennae, maxillary 

 palpi, and mouthparts pale ochraceous yellow; postpedicel oval, 

 0.38 (0.50) mm. long and 0.18 (0.25) mm. wide, 2 (2.2) times as long 

 as wide, sometimes darkened; seta nearly three times as long as 

 postpedicel, bare and shining black except the thickened basal parts, 

 which are brownish yellow. Eyes in profile more than twice as high 

 as wide, sparsely beset with tiny erect whitish hairs. 



All head bristles as brownish yellow as the thoracic bristles and 

 somewhat flattened. Three pairs of incurved lower orbital bristles 

 present, posterior pair always slightly longer than anterior ones and 

 subequal to posterior pair of recurved upper orbital bristles (ors); 

 anterior pair of ors slightly longer than these and about as long as the 

 strongly divergent ocellar bristles; as usual in Tephritidae, the inner 

 verticals are the longest of all head bristles, slightly longer than the 

 outer ones. A distinct genal bristle. 



Thorax pale ochraceous yellow in ground color, 3.1 (3.4) mm. long 

 and 2.3 (2.4) mm. wide; mesonotum densely covered with pale 

 ochraceous yellow dusting and short pale appressed hairs except the 

 narrow bare posterior part in front of scutellum, which is as subshining 

 and sparsely whitish dusted as scutellum; in the dusting of mesonotum
