FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 363 



mesonotum; behind wing base a pointlike black dot. Pleura shining, 

 except for the finely whitish pruinose mesopleuron (anepisternite) 

 and sternopleuron (katepisternite) . The double black spot on inferior 

 part of pleurotergites always present, sometimes yellowish brown; 

 the smaller black spot above hind coxa sometimes absent. Scutcllum 

 ochraceous yellow, shining, with some minute appressed brownish 

 yellow hairs on sides. The large median part of postscutellum yellow, 

 lateral parts brownish black to yellowish brown, postscutellum, 

 rarely, may be entirely yellow. Mediotergite shining and usually 

 wholly intensive testaceous yellow, but sometimes on hind region 

 a pair of large lateral dark spots, yellowish brown to brownish black. 



Thoracic bristles brownish yellow; inferior mesopleural bristle 

 slightly shorter than superior; posterior notopleural bristle usually 

 only two-thirds as long as and much weaker than anterior. Dorso- 

 central pair {dc) in male inserted in anterior fifth to fourth, in female 

 approximately in anterior third, of distance between transverse 

 suture and supra-alar bristles {so) ; dc bristles more widely spaced than 

 prescutellar pair which stands approximately halfway between sa and 

 upper postalar (jpa) bristles (in male slightly nearer jpa). Apical pair 

 of scutellar bristles shorter and weaker than basal pair, parallel to 

 slightly convergent. 



Wings with characteristically modified pattern as in argentiniensis; 

 subapical band is completely absent, except for a brown spot on tip 

 of fourth longitudinal vein. Antebasal band not bordered with 

 brown, yellow with brown tip, much paler than in argentiniensis; 

 costa blackened at tip of humeral cross-vein and at tip of subcosta. 

 Basal band abbreviated and terminated in a translucent brown cloud 

 at tip of apical process of anal cell. Stigma (subcostal cell) long, 

 approximately 3.0 (3.2) times as long as basally broad. First costal 

 section 0.52 (0.54), second 1.02 (1.03), third 0.61 (0.77), and fourth 

 0.43 (0.48) mm. long. Basal section of the fourth longitudinal vein 

 0.76 (1.00), penultimate (or median) 0.29 (0.25), and ultimate 1.16 

 (1.30) mm. long, nearly straight. Inner cross-vein (0.23 (0.27) mm.) 

 parallel to outer cross-vein (0.48 (0.57) mm.). Anal cell with apical 

 process 0.66 (0.76) mm. long, 2.2 (2.4) times as long as apical process 

 (0.30 (0.32) mm.) 



Halteres entirely testaceous yellow but the knob sometimes brownish. 



Coxae, with legs, testaceous yellow. 



Preabdomen 1.7 (1.9) mm. long and 1.2 (1.3) mm. wide, shining 

 ochraceous to testaceous yellow, with golden, shining, appressed, brown- 

 ish black hairs. Third to fourth tergites each with one pair and 

 fifth tergite with two pairs of lateral black spots. Black spots on 

 fourth tergite and basal pair of fifth tergite usually large and sub- 

 equal; black spots on third tergite are generally as small as apical 

 pair of fifth tergite, sometimes they are only brown to yellowish
