paratypes reared from onion at Ames, 
Iowa. After examination of a paratype 
from this series, L. alliovora was 
synonymized with L. trifolii by 
Spencer (1973a). 
Two paratypes of " Agromyza " phaseo - 
lunata Frost have been examined, which 
were recorded from lima bean at 
Bridgetown, N.J. This species also 
clearly represents L. trifolii . This 
new synonymy is formally established 
here . 
In recent years, L. trifolii has 
become known as a pest of truck crops 
in Florida, but the most significant 
damage is caused on cultivated 
chrysanthemums, particularly in 
Florida, California, and in greenhouses 
in Washington, D.C. Chrysanthemum 
cuttings have been regularly supplied 
from a nursery in Florida to a large 
propagating nursery in Kenya, which in 
turn has supplied cuttings to many 
European countries. In this way L. 
trifolii was introduced first into 
Kenya, where it is now widespread on 
many local plants, and subsequently 
has reached most countries in western 
Europe and also Hungary and Yugoslavia. 
There are now wild populations both in 
southern England (where it may not 
have survived the 1982 winter) and in 
a number of districts in France. L. 
trifolii is regarded as a serious pest 
in Europe because of the threat to 
tomato growers, as tomato is another 
favorite host. 
Liriomyza virginica Spencer, new 
species 
(Figs. 801, 802) 
Head. Frons 1.5 times width of eye, 
not projecting above eye in profile; 2 
ors, 2 ori; gena extended at rear, 
0.33 height of eye; 3d antennal 
segment small, round, slightly 
pubescent . 
Mesonotum. 3+1 dc, acr in 4 rows. 
Wing. Length in male 1.4 mm, discal 
cell small, last section of vein M 3+4 
3 times length of penultimate. 
Color. Head yellow, only hindmargin 
narrowly black, but vti distinctly on 
yellow ground; mesonotum deep black, 
distinctly shining, yellow patches at 
hindcorners small, scutellum bright 
yellow, with small black patches 
laterally; mesopleuron largely yellow, 
with narrow black band along lower 
margin; legs with coxae and femora 
bright yellow, tibiae and tarsi 
brownish yellow; squama yellow, margin 
and fringe dark. 
Male genitalia. Aedeagus as in 
figures 801, 802; sperm pump with 
narrow stalk and dark, moderately 
widening blade. 
Host/early stages. Unknown. 
Holotype m. , Virginia, Patrick Co., 
Vesta, 2,800 ft, 30.V.62 (J. R. 
Vockeroth), in CNC. 
Remarks. L. virginica closely re- 
sembles L. schlingeri known from 
California, but the male genitalia 
confirm that the two species are 
distinct . 
Liriomyza sp. (Colorado) 
Colorado, Clear Creek Co., Mt. Evans, 
Doolittle Ranch, 9,800 ft, 1 f., 
8. VII. 61 (C. H. Mann), in CNC. 
Essential characters of this species 
are the entirely black antenna and 
legs; brownish frons with deep black 
orbit; matt black mesonotum, with acr 
in four rows; bright yellow humerus 
and notopleuron; other pleura entirely 
black; squama gray, margin and fringe 
black; and wing length 2.4 mm, with 
discal cell large. 
The matt mesonotum is the most 
distinctive character, readily 
distinguishing the species from L. 
baptisiae , which it otherwise 
generally resembles.
