pale greyish yellow pollinose background, pattern comprised as follows: prescutum 
with pair of rounded sublateral spots and anteromedian black mark, scutum 
with prescutellar black spot; abdomen with Tr + 2 black and a median and a 
pair of sublateral black spots on T3 and T4. Legs uniformly reddish yellow. 
Presutural intra-alar seta absent, two or three postsutural intra-alar setae, ia 
setae therefore o + 2-3. Head profile as Text-fig.50 . METAPHRYNO Crosskey 
Nondescript forms without such pattern. Legs black or partly so, if mainly 
reddish yellow then at least the tarsi black-brown. Intra-alar setae always

Wings distinctly bicolorous, creamy yellowish a near base aad Sateed with ieows 
anteromedially. Interfrontal area very reduced, not more than half as wide as 
a parafrontal. Apical scutellar setae exceptionally strong, as large as or larger 
than the subapicals; subapical scutellar setae widely separated, bases much 
wider apart than distance from insertion of a subapical seta to its corresponding 
basal seta : : (PALIANA Curran, tribe Sturmiini] 
Wings more or less completely hyaline, at most slightly brownish anterobasally. 
Interfrontal area not conspicuously narrow, as wide as or only slightly narrower 
than a parafrontal. Apical scutellar setae (when present) much weaker than 
subapicals; subapical scutellar setae not unusually widely separated, distance 
between bases at most only a little greater than distance from base of one subapical 
to its corresponding basal seta : 5
