Fig. 15. a-d. Dams {Strunieta) luzonae n. sp. a, Mesonotum; b, front view of head; c, abdomen; d, median 
portion of wing, e, D. dorsalis Hendel, median portion of wing. 
by shiny black lines extending longitudinally. 
The yellow postsutural vittae narrow slightly 
posteriorly (Fig. 15^). The scutellum is all 
yellow except for a narrow band of black 
across its base. The metanotum is entirely 
dark, reddish brown to black. Legs: The front 
femora are almost entirely brown to black, 
yellowed only at their bases and apices. The 
middle femora are yellow on the basal one 
third to one half and on the extreme apices; 
they are otherwise brown. The hind femora 
are brown on the apical third, otherwise yel- 
low. The tibiae are dark brown to black. The 
tarsi are yellow except for the brownish apical 
subsegments. Wings: Appearing to fit typical 
dorsalis in all respects. The costal band is well 
developed but does not extend below vein 
Rs except at its apex. Abdomen: Like that of 
dorsalis except for the large spots on the fifth 
tergum and for the more extensively black- 
ened lateral margins (Fig. 15c). Ovipositor: The 
extended ovipositor is approximately 4.0 mm. 
in length. The piercer is 1.27 mm. long by 
0.2 mm. wide at its widest point. The preapical 
setae are situated about 0.07 mm. from the 
tip of the piercer, and the opening of the 
oviduct is 0.23 mm. from the tip. The inver- 
sion membrane is 1.43 mm. by 0.26 mm.; 
the rasper extends to within 0.52 mm. of the 
base of the segment. The basal segment (sev- 
enth abdominal) is about 1.28 mm. by 1.0 
mm.; the spiracles are situated about 0.23 
mm. from the base of the segment, measured 
on the side margins. 
Length: Body, 6.0-7. 0 mm.; wings, 5.0- 
6.0 mm. 
Holotype male, allotype female, and eight 
paratypes (three males and five females) from 
Luzon, Philippine Islands, Oct., 1947 (Q. C. 
Chock). Host unknown. 
The type and allotype are being deposited 
in the U. S. National Museum. The paratypes 
are being distributed in the following collec- 
tions: Bernice P. Bishop Museum, Territorial 
Board of Agriculture and Forestry, Hawaiian 
Sugar Planters’ Association, and the Univer- 
sity of Hawaii.
