Spathimeigenia nigriventris sp. nov. 
Length 7mm. _ Black, grayish pollinose species. 
Female: Front as wide as either eye, frontal vitta opaque dark 
velvety brown, parafrontals and sides of face gray pollinose. 
Frontal bristles in a single row, descending to base of third antennal 
joint, outside of these two pairs of orbital bristles. Eyes bare, 
ocellar bristles strong proclinate, weak bristly hairs on parafacials 
not regularly disposed. Antenne black, the third joint three 
times as long as the second, arista thickened on the basal two- 
fifths, the penultimate joint as broad as long. Vibrissee on an 
approximate level with the front edge of the oral margin, the facial 
ridges bristly on about the lower half. Cheeks about one-seventh 
the eye height, proboscis short and fleshy, palpi normal, yellow. 
Thorax, pleuree and coxze black, grayish pollinose. As viewed 
from behind, the outer thoracic vitte, anterior to the transverse 
suture, are approximately five times as wide as the two inner vitte.

weak pair of apical macrochete. Legs black, the middle tibiz, 
each having a single stout macrocheta on the outer front side near 
the middle. Hind tibize pectinate with a row of bristles of irregular 
length. 
Wings sub-hyaline, apical cell open, ending a little before the 
extreme wing tip. Third longitudinal vein bearing two bristles 
at ts base, and a single bristle at inter-section of the small cross-
