squama and fringe white, margin pale 
brown . 
Male genitalia. Aedeagus as in 
figures 79, 80, ventral bladder 
elongate; sperm pump with large blade 
and distinct central rod. 
Host/early stages. Unknown. 
Holotype m. , Kansas, Douglas Co., 
Lawrence, 27. III. 64; paratypes 9 m. , 
same data; (all J. G. Chillcott). 
Holotype in CNC, paratypes in KAS. 
Remarks. Although this species 
closely resembles M. chillcotti and M. 
subvirens , it is distinguishable by 
the less green abdomen and the 
presence of normally four ori. The 
aedeagus resembles that of M. martini 
Spencer, 1969a, a stem borer in Urtica, 
which is widespread in Canada and 
might be expected to occur in the 
Northern United States. 
Melanagromyza longensis Spencer, 
new species 
(Figs. 56, 57) 
Head. Frons not projecting above eye, 
1.5 times width of eye; 2 reclinate 
ors, 3 inclined ori, orbital setulae 
predominantly reclinate, a sparse 
inner row more proclinate; orbits well 
defined but narrow, not widening 
anteriorly; lunule slightly higher 
than a semicircle; jowls narrow, 0.2 
height of eye; eye distinctly pilose 
above; 3d antennal segment round, with 
short, normal pubescence, arista 
appearing bare. 
Mesonotum. 2 dcr, acr in about 8 rows. 
Wing. Length in male 2.6 mm. 
Color. Ocellar triangle and orbits 
distinctly but moderately shining; 
mesonotum shining blackish green; 
abdomen more distinctly green; squama 
and fringe white. 
Male genitalia. Aedeagus as in 
figures 56, 57; sperm pump large, with 
somewhat irregular blade; 9th sternite 
triangular. 
Host/early stages. Unknown. 
Holotype m. , New York, Long Island, 
Babylon, 9. VIII. 33 (Blanton and 
Borders), in CUI. 
Remarks. Although this species 
somewhat resembles M. virginiensis , n. 
sp., it is readily distinguishable by 
the key characters (couplet 28), and 
the male genitalia of the two species 
are entirely distinct.

This is an aberrant species and its 
correct generic affiliation is un- 
certain. 
The male genitalia (figs. 135, 136), 
the stem galls on Achyranthes (fig. 
137) , and the larval spiracles (fig. 
138) strongly suggest that it does not 
belong in Melanagromyza . The genitalia 
are unlike those of any known Ophio - 
myia , but the form of the puparia does 
suggest affinity with Ophiomyia . 0. 
tiliae , causing twig galls, is known 
to be in this genus, and a typical 
Ophiomyia has been described from Hong 
Kong forming unusual leaf galls. 
There appears to be some justification 
for erecting a monotypic genus to 
accommodate this species. However, 
splitting of this kind is undesirable 
until a more detailed revision of 
Melanagromyza and Ophiomyia on a world 
basis can be undertaken. For the time 
being, therefore, as the adults appear 
externally like a typical Melanagro- 
myza , no generic change is proposed.
