FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 335 



— Apical band of wing not separated from costa, submarginal cell with hyaline 



marginal spot bordered with brown. Abdomen with three pairs of lateral 

 black spots, third to fifth tergites each with one pair; fifth tergite ap- 

 proximately 1.5 times as long as fourth. Eyes in profile twice as high 

 as wide. Postpedicel long, 1.7 times as long as wide. Dorsocentral 

 bristles inserted halfway between suture and supra-alar bristles. Inferior 

 mesopleural bristle absent. Maxillary palpi unusually short and almost 

 semicircular in shape. 5.6 mm. Panamd.

26. Two black to dark brown markings on sides of mesonotum: a short vittalike 



dot below posterior notopleural bristle and a semicircular spot above 

 wing base, below supra-alar bristle. (A small group with exceptional 

 characters.) 27 



— No black markings below posterior notopleural bristle or above wing base • 30 



27. Hind region of mesonotum without black spots, even the usual ones absent; 



four black markings on pleura: a horizontal short linear vitta on propleu- 

 ron attaining upper margin of first spiracle, a double spot on inferior 

 margin of ventral and dorsal pleurotergites, an oval spot above hind 

 coxa, and another on lower hind region of pteropleuron. Yellow apical 

 band entirely separated from rest of wing pattern. 4 mm. Puerto 

 Rico 9 propleuralis, new species (p. 385) 



— Hind region of mesonotum with the usual pair of lateral black spots, each be- 



tween prescutellar and upper postalar bristles; between these another 

 pair of black spots nearer to scutellar suture than the usual pair (some- 

 times these are absent in rudolphi) . Propleura without black markings. 

 Apical band of wing connected with rest of pattern in submarginal cell 

 (atelesta group) 28 



28. Pleura with three black markings: inferior part of sternopleuron entirely black, 



one black spot on pteropleuron and another above hind coxa. The four 

 black spots on hind region of mesonotum almost equal in size. Black 

 markings below posterior notopleural bristle and above wing base form 

 an interrupted black vitta. Mesonotum whitish yellow dusted, with three 

 reddish brown dusted vittae (the two lateral are broad, the median is 

 linear). Scutellum with a pair of laterobasal brown spots. Third to 

 fifth abdominal tergites each with a pair of lateral black spots. Basal 

 part of second basal cell hyaline. 3-4 mm. Peru.

— Pleura without black markings. Second basal cell wholly yellow. Larger 



species 29 



29. Inner pair of four black spots on hind region of mesonotum considerably 



smaller than lateral pair, rarely absent. Third and fourth abdominal 

 tergites of male each with one pair of black to blackish brown small lateral 

 spots (third tergite sometimes spotless) ; fourth to sixth tergite of female 

 each with one pair of lateral black spots (sometimes third tergite also 

 marked with a pair of dark spots) . Subapical yellow band of wing some- 

 times very pale. Dorsocentral bristles inserted in line with supra-alar 

 bristles or slightly before them. 6.5-7.5 mm. Southern Brazil: SSo 

 Paulo, Santa Catarina .... cf 9 rudolphi (Lutz and Lima) (p. 395) 

 — Four black spots on hind region of mesonotum equal in size. Third to fifth 

 tergites of male each with a pair of lateral black spots, the pair on fifth 

 tergite usually elongated. Dorsocentral bristle pair slightly behind line 

 of supra-alars. Black spot below posterior notopleural bristle large.

the usual pair. 5 mm. Paraguay cf tripunctata Hendel
