We take pleasure in naming this inter- 
esting species after Greg McMinn from 
the Southern Weeds Infestation 
Laboratory, Leland, Miss., who 
accompanied us to the Experimental 
Forest and discovered the mines. 
Cerodontha ( Poemyza ) pygmaea (Meigen) 
(new to U.S . A. ) 
(Fig. 562) 
Agromyza pygmaea Meigen, 1830: 183. 
Holotype from Germany lost. 
Cerodontha ( Poemyza ) pygmaea , Spencer, 
1969a: 133; Nowakowski, 1973: 127. 
This species can now be confirmed in 
the United States from New York, 
Ithaca, two males, one female, 21.V.67 
(R. A. Dunn), in CUI. It is common in 
Ontario and has been recorded in 
Quebec, Labrador, and Alaska; it is 
widespread in Europe. C. pygmaea is a 
typical Poemyza with a narrow, high 
lunule (fig. 540, A), closely 
resembling C. incisa and other 
species, but it is immediately 
distinguishable by the dark squamal 
fringe. 
Cerodontha ( Poemyza ) pygminoides 
Spencer 
(Fig. 567) 
Cerodontha ( Poemyza ) pygminoides 
Spencer, 1981: 183. Holotype male 
from Inyo Co., Calif., in UCD. 
The unique holotype was slightly 
damaged, lacking the third antennal 
segment and all orbital bristles. 
Another male has now been identified 
from Colorado, Boulder, Flagstaff 
Canyon, 5,800 feet, "on side of 
stream," 10. VI. 61 (C. H. Mann), in 
CNC. The arrangement of orbital 
bristles is normal, with two ors and 
two ori, and the third antennal 
segment is black, small, obtusely 
angulate, with the arista slightly 
pubescent and as long as the eye width. 
Cerodontha ( Butomomyza ) angulata (Loew) 
(Figs. 583-588) 
Lectotype female from Pennsylvania, 
designated by Frick, 1957b: 202, in 
MCZ . 
Phytobia (Poemyza) angulata, Frick, 
1957b: 202. 
Cerodontha ( Dizygomyza ) angulata , 
Spencer, 1969a: 113. 
Cerodontha ( Butomomyza ) angulata , 
Nowakowski, 1973: 152. 
Cerodontha ( Butomomyza ) neptis (Loew, 
1869: 50). Lectotype female, from 
District of Columbia, designated by 
Frick, 1957b: 202, in MCZ. 
Cerodontha ( Butomomyza ) semiposticata 
(Hendel, 1920: 131). Lectotype 
female from Germany, designated by 
Nowakowski, 1967: 634. 
In his monograph of this genus, 
Nowakowski (1973) includes three 
closely related species from Europe in 
the C. angulata group. The male 
genitalia of eight specimens have now 
been examined from North Carolina, 
and it seems clear that several species 
close to C. angulata are also present 
in the United States. The aedeagus of 
one such specimen from North Carolina, 
Swain County, Indian Gap, Great Smoky 
Mountains National Park, 5,200 feet, 
3. VII. 57 (C. D. Hines), in CNC, is 
shown in figures 585, 586. Another 
specimen from North Carolina is 
described here as £. (B. ) fusculata , 
n. sp., but further splitting is con- 
sidered undesirable in the absence of 
information on host plants and early 
stages. Most, if not all, of these 
species will prove to be leaf miners 
on Carex , but surprisingly not a 
single specimen has so far been reared 
in this group in North America. 
A male syntype, which can be associ- 
ated with the female lectotype, 
although it was not mentioned in the 
original description, has now been 
examined, and the aedeagus and epandri- 
um are shown in figures 583, 584. 
Cerodontha ( Butomomyza ) fusculata 
Spencer, new species 
(Figs. 577, 578) 
Head. Frons narrow, little wider than 
eye, not projecting above eye in 
Agromyza angulata Loew, 1869: 47
