FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 385 



Preabdomen 1.3 (1.5) mm. long and 1.2 (1.3) mm. wide, with five 

 pairs of lateral black spots; second to sixth tergites each with one pair 

 of transverse-oval spots, the two longitudinal rows of black spots 

 convergent towards the ovipositor. Fifth tergite (0.23 (0.25) mm.) 

 slightly longer than the sixth (0.18 (0.23) mm.). 



Ovipositor sheath in the specimens examined strongly flattened 

 dorsoventrally, entirely shining testaceous yellow and covered with 

 very short and fine, appressed, brownish yellow hairs, slightly shorter 

 (0.52 (0,54) mm.) than basally wide (0.57 (0.63) mm.), at apex only 

 0.30 (0.32) mm. wide and basally in profile 0.16 (0.18) mm. high.

Tomoplagia propleuralis, new species 



Figure 94; Plate 20, figure 5 



A medium-sized, very well defined species, readily distinguished from 

 all known species by the modified wing pattern (the apical band being 

 separated entirely from the others) and by the absence of the pair of 

 lateral black spots between the upper postalar and prescutellar bristles, 

 on the hind part of the mesonotum. This species is the only known 

 Tomoplagia which has a short linear black vitta on the propleura, 

 above the anterior spiracle. Unfortunately the only specimen has 

 become wet by some greasy liquid, thus the ground color and the 

 morphological characters can be noted but the pruinosity is obscured. 



Female: Length 4 mm.; wing 4.5 mm. long and 1.6 mm. wide, 

 relatively narrow, 2.8 times as long as wide. 



Head testaceous yellow, 0.73 mm. long, 1.43 mm. wide, and 1.13 

 mm. high, Frons at vertex 0.48, at anterior margin 0.36 mm. wide, 

 and in median line 0.54 mm, long, relatively narrow, since it is con- 

 siderably longer than wide at vertex. Antennae and mouthparts 

 testaceous yellow; postpedicel wide-oval, 0.27 mm, long and 0,20 mm. 

 wide, 1,35 times as long as wide; seta bare, shining black, except the 

 thickened transparent yellow basal third, about three times as long 

 as postpedicel. Eyes in profile 1 ,6 times as high as wide, very sparsely 

 beset with microscopically short fine erect and whitish hairs; oral 

 margin of the impressed mesofacial plate raised and slightly prominent. 



Head bristles brownish yellow and somewhat flattened; three pairs 

 of incurved lower orbital bristles (ori) , anterior pair much shorter and
