(fig. 181) and the male genitalia 
(figs. 182, 183) associate this 
species correctly with Ophiomyia , to 
which it is now transferred. 
Steyskal (1972b: 2) recorded a single 
male from Michigan, and another male 
has now been seen from Thalman, Glynn 
County, Ga. (CUI) . 
Ophiomyia monticola Sehgal (new to 
U.S.A.) 
(Figs. 164-166) 
Ophiomyia monticola Sehgal, 1968: 60; 
Spencer, 1969a: 90. Holotype male 
from Alberta in CNC. 
This species is widespread in northern 
Canada and has also been recorded from 
Alaska. Two males have now been 
identified from Colorado, Boulder 
County, Nederland, 8,500 feet, and 
Caribou, 10,000 feet, both 18. VI. 61 
(C. H. Mann), in CNC. 
Although 0. monticola closely resembles 
0. banf fensis , it is readily distin- 
guishable by the darker squama and the 
conspicuously broad facial keel. 
Ophiomyia parva Spencer, new species 
(Figs. 307-309) 
Head (fig. 307). Frons little wider 
than eye, not projecting above eye in 
profile; 2 ors, 2 ori, orbital setulae 
sparse, reclinate; ocellar triangle 
broad but short, apex not extending to 
level of lower ors; gena narrow, 0.17 
height of eye, forming angle of about 
70°; vibrissal fasciculus in male 
(inconspicuously fused on 1 side) 
short, regularly curving; facial keel 
broad, high, flattened above but 
without central furrow. 
Mesonotum. 2 dc, acr sparse, in some 
6 rows . 
Wing. Length in male 1.6 mm, C 
extending to M 1+2, last and 
penultimate sections of M 3+4 equal, 
inner crossvein only slightly beyond 
midpoint of discal cell. 
Color. Ocellar triangle, mesonotum, 
and abdomen strongly shining black; 
squama gray, margin and fringe black. 
Male genitalia. Aedegus as in figures 
308, 309, distiphallus strongly 
pigmented. 
Host/early stages. Unknown. 
Holotype m. , New Mexico, Otero Co., 
White Sand National Monument, 5. VIII. 66 
(R. L. Brumley) , in UCD. 
Remarks. 0. parva closely resembles 
0. lassa from northern California, but 
the heavily pigmented aedeagus is 
distinctive and confirms its rank as a 
species. 
Ophiomyia parvella (Spencer), new 
combination 
(Figs. 200-202) 
Melanagromyza parvella Spencer, in 
Spencer and Stegmaier, 1973: 46. 
Holotype male from Florida in USNM. 
The male genitalia show the close 
relationship of this species to 0. 
abutilivora , which is confirmed as an 
Ophiomyia . The minute size of 0. 
parvella suggests that it may be a 
leaf miner, possibly the species 
forming long narrow mines on Lantana 
(fig. 202). Unfortunately it has 
never been reared, but it is common in 
Florida (Spencer and Stegmaier, 1973: 
63). Another comparable leaf miner 
now accepted in Ophiomyia is 0. 
pfaf f iae (Spencer, 1963a), known in 
Venezuela (Spencer, 1973b: 28). 
Ophiomyia praecisa Spencer 
(Figs. 221-223) 
Ophiomyia praecisa Spencer, 1969a: 92. 
Holotype male from Alberta in CNC. 
Ophiomyia aestimabilis Spencer, 1981: 
69. Holotype male from California 
in CAS. NEW SYNONYM. 
This species was described from the 
Banff area in the Canadian Rockies at 
4,500 feet.
