black, as in P. volatilis , and this 
was previously treated merely as 
melanism (Spencer, 1976a: 299). 
However, it is now noted that the 
sperm pump had the blade narrow in 
these specimens, exactly as in the 
male from Colorado (fig. 1020). The 
Lapland population is therefore now 
considered to be identical with P. 
volatilis rather than with P. mikii. 
GENUS PARAPHYTOMYZA ENDERLEIN 
One new species is described and one 
species is recorded as new to the 
United States. Two species are 
briefly discussed but not formally 
described in the absence of males. 
Paraphytomyza coloradensis Spencer, 
new species 
(Figs. 1042, 1043) 
Head. Frons broad, twice width of 
eye, not projecting above eye in 
profile; 2 ors, 2 ori, lower ori 
substantially weaker (all missing, 
detectable only from basal pits); 
parafacial pronounced, gena angular, 
0.33 height of eye; (3d antennal 
segment missing on both sides). 
Mesonotum. 4+2 dc , 4th to 6th small 
but well differentiated from acr, 
these in 4 rows. 
Wing. Length in male 2.75 mm, discal 
cell small, last section of M 3+4 4 
times length of penultimate. 
Color. Frons largely bright yellow, 
somewhat darkened adjoining antennae; 
orbit and parafacial entirely yellow; 
gena and face grayish; 1st antennal 
segment yellowish, 2d gray, 3d 
(missing) almost certainly black; meso- 
notum and scutellum uniformly grayish 
black; humerus, notopleuron, and upper 
margin of mesopleuron yellow, pleura 
otherwise grayish black; legs largely 
black but all knees distinctively 
yellow; squama yellowish, margin and 
fringe dark. 
Male genitalia. Aedeagus as in 
figures 1042, 1043; sperm pump with 
large rounded blade; surstylus large, 
rounded, with fringe of weak hairs. 
Host/early stages. Unknown, almost 
certainly Lonicera . 
Holotype m. , Colorado, Clear Creek 
Co., Mt. Evans, Echo Lake, 10,600 ft, 
23. VII. 61 (C. H. Mann), in CNC. 
Remarks. The male genitalia of this 
species indicate its relationship with 
P. lonicerina . The aedeagus of P. 
coloradensis is entirely symmetrical, 
but in V_. lonicerina (fig. 1041) it is 
distinctively asymmetrical. 
Paraphytomyza luteoscutellata (Meijere) 
(new to U.S . A. ) 
(Figs. 1044-1046) 
Phytomyza lonicerae Brischke, 1881: 
257. Types from Germany believed 
lost. 
Phytagromyza luteoscutellata de 
Meijere, 1924: 143, nom. nov. for 
Phytomyza lonicerae Brischke, 
preoccupied by P. lonicerae 
Robineau-Desvoidy, 1851: 396. 
Phytagromyza xylostei (Robineau- 
Desvoidy) sensu Hendel, 1932: 275. 
Paraphytomyza luteoscutellata, Spencer, 
1969a: 206. 
The status of this species has been 
confused but was clarified by the 
synonymy given here when the species 
was first discovered in Canada 
(Spencer, 1969a). 
P. luteoscutellata somewhat resembles 
jP. orbitalis but is generally paler. 
The scutellum is frequently, but not 
always, partially yellow, whereas in 
P. orbitalis it is consistently 
blackish. 
Specimens have been seen from New York 
and Wisconsin, and leaf mines have 
been found in Minnesota. The species 
is probably widespread in the North- 
eastern States.
