2 ( 1 ). 
Mesonotum yellow adjoining scutellum, at least at 
hindcorners, inner postalar on yellow 2 
Mesonotum largely gray adjoining scutellum, with at 
most small yellow patches at hindcorners, inner 
postalar on dark area 3 
Mesonotum entirely yellow adjoining scutellum, with 
central yellow area extending forward slightly be- 
yond level of dc 1 H. kefi Steyskal 
Synopsis. Frons, orbit, and all antennal segments 
entirely yellow; 1 ors, 3 ori; acr in 2 rows; wing 
length 1.5 mm; male genitalia with aedeagus having 
extended distal tubule (fig. 860); hypandrium with 
broad lobe at base (fig. 861); surstylus with 4 
closely adjoining teeth (fig. 862). 
Host/Early Stages. Physalis viscosa (Texas), Solanum 
triquetrum (Texas), S. umbelliferum (California)^ 
Larva forming short linear mine. 
Distribution. California; new records: Texas, 
Travis Co., Austin, 3m., 1 f . , ex leaf mines on 
Solanum triquetum , 9. IV. 80; 2m., ex leaf mines on 
Physalis viscosa , 21. IV. 80; (all S. Tavormina). 
References. Steyskal, 1980: 146; part 2, p. 299. 
Note. In all specimens seen from Texas and in some 
of type series from California, mesonotum is 
distinctly yellow adjoining scutellum (particularly 
when viewed from rear). Only in darkest specimens 
does mesonotum appear largely gray (see couplet 4 ) 
and such specimens may be difficult to differenti- 
ate from H. minutus. 
Mesonotum dark centrally adjoining scutellum but in- 
ner postalar arising from yellow area 
7 H. palliatus (Coquillett) 
Synopsis. Small species, wing length 1.5 mm; all 
antennal segments and entire hindmargin of eye yel- 
low; mesonotum with 3+1 well-developed dc, largely 
grayish, with large yellow area at hindcorners; acr 
irregularly in 2 rows; scutellum largely yellow; 
male genitalia unknown. 
Host/Early Stages. Portulaca sp. No information on 
leaf mine Or early stages. 
Distribution. New Mexico.

that it is not certain that this species correctly
