 0.11 (0.18) mm. high in profile) and entirely shining testaceous yellow, 

 evenly covered with appressed minute brownish yellow hairs; nearly 

 as long (0.63 (0.67) mm.) as wide at base (0.75 (0.79) mm.) and much 

 longer than wide at apex (0.43 (0.43) mm.). Median and apical parts 

 of ovipositor testaceous yellow, apical shinmg and translucent, long-

 Tomoplagia reimoseri Hendel, 1914, p. 39. 



This seems to be a common medium-sized species in northern 

 Argentine, southern Brazil, and Paraguay; it belongs to the pleuralis- 

 reimoseri group, differing from the allied species by the characters 

 given in the key. 



Male: Length of body 4.0 (4.3) mm.; wing 4.2 (4.5) mm. long and 

 1.8 (1.9) mm. broad, slightly more than 2.3 times as long as broad. 



Head, antennae, and maxUlary palpi testaceous yellow, only labella 

 brown; 0.70 (0.73) mm. long, 1.27 (1.34) mm. wide and 1.02 (1.11) mm. 

 high. Frons at vertex 0.59 (0.57) mm., at anterior margin 0.41 (0.39) 

 mm. wide and on median line 0.50 (0.50) mm. long. Ocellar plate 

 slightly raised and covered with many scalelike whitish hairs; ocelli 

 transparent golden yellow. Oral margin of mesofacial plate raised 

 and prominent. Inferior region of cerebral plate only slightly raised. 

 Maxillary palpi broad, sickle-shaped, tapering into a pointed tip. 

 Postpedicel very broad-oval, 0.20 (0.20) mm. long and 0.16 (0.18) 

 mm. wide, only 1.1 (1.2) times as long as wide; seta bare, shining black 

 except for the thickened basal third, which is testaceous yellow; 

 approximately 3 times as long as postpedicel. Eyes in profile 0.87

 high as wide; inferior region of postcranium in profile 0.18 (0.18),
