This species has previously been known 
only from the type series. Leaf mines 
(fig. 823) were found in Arkansas, Hot 
Spring County, Lake Catherine State 
Park, on Lathyrus sp., 18.V.79 (KAS 
and GCS) , in KAS, and a single male 
emerged 11. VI. 79. It is distinctive 
in having both vertical bristles on a 
yellow ground and the mesonotum 
uniformly matt black. The aedeagus is 
shown in figures 821, 822. 
Liriomyza montella Spencer, new species 
(Figs. 744, 745) 
Head. Frons twice width of eye, 
projecting only narrowly above eye in 
profile; 2 reclinate ors, 2 inclined 
ori, orbital setulae sparse, reclinate; 
gena about 0.33 height of eye; 3d 
antennal segment small, round. 
Mesonotum. 3+1 dc, acr sparse, in 2 
rows. 
Wing. Length in male 1.5 mm, discal 
cell small, last section of vein M 3+4 
slightly more than 3 times length of 
penultimate. 
Color. Frons, orbit, face, and 
antenna yellow; hindmargin of eye 
narrowly black, with vte on dark 
ground, vti on yellow; mesonotum matt 
black, scutellum broadly dark at 
sides, narrowly yellow in center; 
humerus and notopleuron yellow, pleura 
otherwise blackish gray; legs largely 
black but femora with all knees 
yellow; squama and fringe yellowish, 
margin only slightly darker; abdomen 
largely black. 
Male genitalia. Aedeagus as in 
figures 744, 745. 
Host/early stages. Unknown. 
Holotype m. , Colorado, Clear Creek 
Co., Mt. Evans, Timber line, 11,700 ft, 
22. VII. 61 (C. H. Mann), in CNC. 
Remarks. The male genitalia indicate 
close relationship between this 
species and L. balcanoides Sehgal, 
1971, but the latter has the meso- 
pleuron and legs largely yellow. L. 
montella somewhat resembles L. 
elevata , n. sp., caught at the same 
locality, but it has the third 
antennal segment darkened. 
Liriomyza montis Spencer, new species 
(Figs. 764, 765) 
Head. Frons 1.5-2 times width of eye, 
narrowly projecting above eye in pro- 
file; normally 2 ors (on one side in 
one specimen 3) and 2 ori, orbital 
setulae sparse, reclinate; gena 
extended at rear, 0.33 height of eye; 
3d antennal segment slightly longer 
than broad, rounded at end. 
Mesonotum. 3+1 strong dc, acr 
irregularly in 4 rows. 
Wing. Length in male 2.3 mm, discal 
cell large, last section of vein M 3+4 
only slightly more than twice length 
of penultimate, in ratio 30:13. 
Color. Frons, orbit, and antenna 
bright yellow, hindmargin of eye black 
to base of vti; mesonotum uniformly 
black, predominantly matt, with only 
weak subshine, scutellum completely 
yellow; mesopleuron yellow on upper 
quarter, black below; legs with femora 
largely dull yellow, with blackish 
striations, tibiae and tarsi black; 
squama yellowish gray, margin and 
fringe black. 
Male genitalia. Aedeagus as in 
figures 764, 765; sperm pump with 
narrow stalk and only slightly 
widening blade; surstylus with 2 stout 
bristles and several hairs at end. 
Host/early s tage s . Unknown . 
Holotype m. , Colorado, Clear Creek 
Co., Mt. Evans, Summit Lake, 12,000 
ft, 24. VII. 61 (B. H. Poole); paratype 
m., Colorado, Boulder Co., near Ward, 
11,500 ft, on tundra, 4. VII. 61 (C. H. 
Mann); both in CNC. 
Remarks. Although this species 
closely resembles L. sabaziae , the 
male genitalia indicate that the two 
are not closely related.
