of next 2 segments and diffuse basal part of last (5th) preabdominal 
segment yellowish; entire 5th tergite pruinose; yellowish parts and 
entire 5th tergite covered with whitish pile; apical part of basal 
tergite and dark apical parts of 3rd and 4th tergites covered with 
moderately dense and long, recumbent rufous hairs; spiracles of 4th 
tergite narrowly within apical corners of tergite; those of 5th tergite 
narrowly within lateral margins of tergite opposite base of ovipositor; 
basal segment of ovipositor piceous, with many erect whitish hairs.

This species, as shown in the preceding key, is apparently most 
closely related to Plagiostenopterina marginata (Wulp) and to P. 
olivacea Hendel, should the latter be found definitely to belong to 
Meringomeria.

One pair, Selangor Gombak Forest Reserve, tree platform, 9 
Nov. 10, 1962, @ Jan. 19, 1963. Walker described a female from 
Burma, Hendel expressed an opinion that the species might be related 
to P. trivittata (Walker), and Frey made the combination and recorded 
the species from Palawan. The Malayan specimens agree well with 
Walker’s description and are indeed close to P. trivittata (see key, p. 7).

Plagiostenopterina (Stenopterella) trivittigera Malloch, 1981, Proc. U.S. Nat. Mus., 
Vol S,.10. 15, p.. 17. 
Selangor Gombak Forest Reserve, tree platform, 2 7,19, May 7, 
1961; 2 9, May 13, 1961; 19, Sept. 29, 1962. These are apparently 
the second recorded captures. The specimens agree well with the 
type from Singapore in the USNM.
