Another species in this group, L. 
andina Malloch (see Spencer, 1963a: 
353), is present in Chile, and the 
host was discovered to be Plantago 
during collecting in Chile by KAS in 
January 1978.

Liriomyza commelinae (Frost)

Agromyza commelinae Frost, 1931: 72. 
Ho lo type male from St. Vincent in 
USNM. 
Liriomyza commelinae , Frick, 1952a:

Spencer, 1963a: 361; Spencer and 
Stegmaier, 1973: 101. 
Adults of this species are unusual in 
having the third antennal segment 
greatly enlarged in the male (fig. 
659). However, the general coloration 
is typical of Liriomyza , and the 
stridulating mechanism is developed 
normally. 
The larva, puparium, and leaf mine are 
atypical of Liriomyza . The puparium 
is black, elongate, and remains in the 
mine after pupation. Each posterior 
spiracle (fig. 662) has one greatly 
elongated, hooklike "bulb" and two 
minute ones at its base, generally 
resembling the form found in many 
species of Butomomyza and Dizygomyza 
(see fig. 588). The frass is 
deposited in large widely spread 
lumps, whereas the normal practice in 
Liriomyza is deposition in slender 
strips at alternate sides of the mine. 
It is suggested that this is a 
primitive annectant species between 
Liriomyza and Cerodontha , subgenus 
Dizygomyza , with the adult having 
developed normal characters of Lirio— 
myza apart from the enlarged male 
third antennal segment, whereas 
primitive characters of the larva, 
including its feeding habit, have been 
retained, showing clearly the link 
with Dizygomyza . This is thus a 
unique species, with evolution in the 
adult and larva not having proceeded 
in parallel. Although the essential 
genetic structure of Liriomyza must be 
present in the larva, the larva remains 
dominated by primitive genes of the 
Dizygomyza type . 
L. commelinae is essentially a neo- 
tropical species, occurring widely in 
suitable habitats from Argentina to 
Venezuela and the Caribbean and just 
reaches the United States in Florida.

Holotype female from Illinois in 
INHS. 
Frick (1959: 403) commented that this 
"is the most diverse North American 
species of Liriomyza known to me." 
This comment is justified, as, despite 
the characteristic color of Liriomyza , 
the shape of the head (fig. 752) and 
the long, slender orbital bristles 
suggest that the species may in fact 
belong in Amauromyza . However, no 
formal generic change appears justi- 
fied until the correct status of the 
species can be established from ex- 
amining the male genitalia.
