Figures 11, 24; Map 22 



Female: Averages 2.8 mm. (2.2-3.3) in length. Black except for 

 the tarsi, knees, and apices of mid- and hindtibiae, occasionally all of 

 fore tibiae and wing veins. Abdomen, viewed laterally, narrowly oval; 

 longer than head and thorax combined; averaging in length 1.5 mm. 

 (1.2-1.7); sixth tergum dorsally, longer than three and four combined; 

 sculpturing Hmited to lower anterior half of lateral surface; rest of 

 surface shiny black; ninth tergum short, averaging .14 mm. (.12-.17) 

 in length. Internal genitalia average 1.5 mm. in length and .77 mm. 

 in height; thus height is about half the length; dorsal valves narrow 

 and black for horizontal length and turn dorsally, anteriorly, with 

 ventral valves at less than a right angle in relation to the horizontal 

 axis; stylet arch in an oblique plane. Propodeum rounded with a 

 deep, narrow concavity occupied by a median furrow, wider at top 

 and dehmited laterally by complete lateral carinae to base; central 

 carina may extend from dorsal margin for half to three-quarters 

 length of median furrow; spaces in furrow with shiny, unsculptured 

 surfaces; lateral areas absent or if present very narrow. Thorax with 

 the tegula black. Antenna with the scape black; first segment of the 

 funicle slightly longer than pedicle, itself longer than wide and trun- 

 cate distally; next four segments subequal to square and truncate dis- 

 tally; distal three segments grouped closely together to form a slightly 

 expanded club. Legs with black infuscation on all femora and tibiae, 

 except occasionally fore tibiae; tarsi may have black infuscation on 

 dorsal surface. Wing veins light brown and linear; marginal vein 

 longer than postmarginal, averaging .32 mm. (.25-. 35) in length and 

 postmarginal averaging .22 mm. (.20-.22). 



Male: Averages 1.9 mm. (1.6-2.2) in length. Wing veins are dark 

 brown; marginal longer than postmarginal, averaging .27 mm. 

 (.25-.30), and postmarginal averaging .16 mm. (.15-. 17) in length. 



Types: 8 females and 10 males; holotype female and allotype male 

 in the U.S. National Museum collection, Washington, D.C. (USNM 

 66057). Paratype females in the U.S. National Museum, Bugbee col-
