FRUIT FLIES OF GENUS TOMOPLAGIA — ^ACZEL 401 



to the outer vertical bristles. Genal bristle distinct, brown with 

 golden lustre. 



Thorax with scutellum 1.7 (1.6) mm. long and 1.3 (1.1) mm. wide, 

 pale testaceous to ochraceous yellow in ground color; mesonotum 

 evenly covered with pale, testaceous yellow dusting and shining pale 

 yellow appressed short hairs except for the very narrow hind margin, 

 which is bare and shining; there are no structural or dusted vittae 

 present. On the hind region of the mesonotum the usual pair of 

 lateral black spots present, in this species they are small; beneath (and 

 behind) wing base a small brownish black dot. Pleura without black 

 spot. Scutellum whitish dusted, only linear basal border shining. 

 Postscutellum and metanotum intensive testaceous yellow, shining, 

 without black spots. 



Thoracic bristles brownish yellow; only the upper pair of meso- 

 pleural bristles present; hind notopleural bristle only half as long as 

 and much weaker than fore pair. Dorsocentral pair placed in 

 transverse suture or slightly behind, more widely spaced than prescu- 

 tellar pair, which is inserted far before level of upper postalar bristles 

 close to level of supra-alar pair. Apical pair of scuteUar bristles 

 crossed and considerably shorter than basal. 



Coxae and legs pale testaceous yellow, only distitarsi of mid and 

 hind legs dark brown. 



Wings with the general pattern of the genus; it is characteristic of 

 this species that the yellow basal band is abbreviated, ending in a 

 subquadrangular semiopaque dark brown spot distad to anal vein, 

 at tip of apical process of anal cell. Subcostal cell (stigma) 2.2 (2.3) 

 times as long as basally broad. First costal section (stigma) 0.57 

 (0.50), second 1.38 (1.34), third 0.79 (0.70), and fourth 0.52 (0.45) mm. 

 long. Basal section of the fourth longitudinal vein 1.13 (1.02), 

 median (penultimate, between the cross-veins) 0.32 (0.27), and 

 ultimate 1.30 (1.11) mm. long. Inner cross-vein 0.27 (0.26) mm. long 

 and more obliquely placed than the outer cross-vein (0.51 (0.43) mm.). 

 Entire anal cell 0.59 (0.59) mm. long, 2.6 (3.1) times as long as apical 

 process (0.23 (0.19) mm.) 



Halteres pale ochraceous yellow. 



Preabdomen 1.7 (1.7) mm. long and 1.3 (1.2) mm. wide, long-oval 

 testaceous yellow with appressed fine brownish yellow hairs and with 

 only two pairs of lateral black spots; third to fourth tergites each 

 with pair of small lateral black spots, equally widely spaced. Fifth 

 tergite (0.41 (0.41) mm.) very long, 2.3 (2.5) times as long as the fourth 

 (0.18 (0.16) mm.). 



Postabdomen testaceous yellow; epandrium long-oval, with nor- 

 mally shaped surstyli. Apparently only the anterior pair of the 

 shining black gonapophyses present. 



Female: Unknown.
