78. Eurytoma picea, new species 



Map 35 



Female: Black except for brown wing veins, yellow base of scape, 

 and extremities of femora, tibiae, and whitish tarsi. Length averages 

 3.6 mm. (3.1-4.1). Abdomen oval from lateral and dorsal views; 

 medium lateral compression so that greatest width in cross section is 

 nearer middle, sixth tergum about two times the length of the fifth; 

 smooth and shiny surface except for fine scaling on lower, anterior 

 half; ninth tergum elongate, averaging .22 mm. (.24-.25) in length. 

 Internal genitalia with narrow dorsal valves that turn dorsally, ante- 

 riorly, with the ventral valves at slightly less than a right angle so 

 that stylet arch and fulcral plate are in an oblique plane; dorsal 

 valves dark brown to black for entire length; whole structure aver- 

 ages 1.7 mm. (1.6-1.8) in length and .97 mm. (.95-1.0) in height. 

 Propodeum narrowly concave with a wide, shallow, complete median 

 furrow that narrows toward base; central carina about one-quarter 

 to three-quarters length of furrow; surface between horizontal ridges 

 within fmTow, smooth and shiny; lateral areas narrow or nonexistent. 

 Antenna with a flagellum of five truncate, slightly moniliform, seg- 

 ments; sixth separated from the terminal unit by a shallow annula- 

 tion. Legs with black to dark-brown infuscation on all femora and 

 tibiae. Wing veins brown; marginal about two times the width of 

 postmarginal, quite long, averaging .40 mm. (.35-.50) in length; post- 

 marginal averages .27 mm. (.22-. 32) in length.
