and other authors in defining the 
genus Haplomyza . However, as Steyskal 
(1980) rightly noted, although L. 
togata closely resembles true Haplomyza 
species (now Haplopeodes ) , the male 
genitalia indicate that togata 
correctly belongs in Liriomyza > 
L. douglasii was described from 
California before the correct identity 
of L. togata was known. The aedeagus 
of L. douglasii (figs. 831, 832) is 
obviously identical to that of the 
lectotype of L. togata illustrated by 
Steyskal (1980: figs. 1 A, 1 B) . L. 
douglasii , therefore, is synonymized 
here with L. togata . 
There is some variation in the 
arrangement of the orbital bristles in 
this species. In the lectotype there 
is only one strong reclinate ors and 
two inclined ori, but in three other 
specimens examined there are 1+3. The 
wing length is not 1.2 mm as stated by 
Me lander but ranges from 1.6 to 1.75 
mm. 
Among the four specimens included in 
the type series of L. douglasii , one 
female from California, Alameda 
County, Albany, was reared from 
Artemisia douglasiana , 13. VIII. 48 (K. 
E. Frick, Lot 41 - 3). Details of the 
leaf mine are not available. 
Liriomyza trifoliearum Spencer 
(Figs. 703-706) 
Liriomyza trifoliearum Spencer, in 
Spencer and Stegmaier, 1973: 107. 
Holotype male from Florida in USNM. 
This species was originally misidenti- 
fied by Frick and other American 
workers as L. pictella . However, L. 
pictella is now restricted to the 
unique holotype from "San Francisco." 
At the time of its description L. 
trifoliearum was known as a leaf miner 
on only two hosts, Medicago and 
Trifolium . It was subsequently 
recorded on Coronilla and Pisum . 
A series of six specimens has been 
examined from Washington, Benton 
County, Prosser, reared in April 1950 
from Solanum sarachoides (Frick, Lot 
50 - 16). Despite the improbable 
host, it is clear that these specimens 
represent L. trifoliearum , which has 
been recorded from the same locality 
on Medicago sativa (Frick, Lot 229 - 
1). Records were given by Spencer 
(1981: 278) of caught specimens from 
13 counties in California. It was 
assumed that the hosts of such 
specimens would be in the Fabaceae, 
but it now remains to be established 
whether the species occurs regularly 
on Solanum or even other hosts, or 
whether its occurrence on Solanum in 
Washington represents merely an 
unusual local transference. 
Liriomyza trifolii (Burgess) 
(Figs. 838-840) 
Oscinis trifolii Burgess, 1880: 201. 
Neotype male from Indiana, desig- 
nated by Spencer, 1965a: 37, in USNM. 
Liriomyza phaseolunata Frost, 1943: 
256. NEW SYNONYM. Holotype 
missing, 2 paratopotypes from New 
Jersey in PSU. 
Liriomyza trifolii , Frick, 1952a: 405; 
1959: 410; Spencer, 1965a: 37; 
1973a: 226; 1981: 281; Spencer and 
Stegmaier, 1973: 109. 
Liriomyza alliovora Frick, 1955: 88. 
Holotype male from Iowa in USNM 
(synonymy established by Spencer, 
1973a: 226). 
This species is highly polyphagous. 
Stegmaier (1966a) listed 55 hosts in 
10 families in Florida. L. tri - 
folii has a wide distribution in the 
Eastern United States, and as often 
occurs in such cases, it has been 
described on several occasions by 
different authors. Distinctive char- 
acters are the yellow hindmargin of 
the eye and the matt grayish black 
mesonotum, with acrostichals 
irregularly in some four rows in front 
but sparse or even lacking behind the 
second dorsocentral . 
An unexpected and favored host is 
Allium , and Frost (1943) included in 
his description of Agromyza allia 20
