Very little is known about the Mexican fauna of
Uroleucon
; only 4 species have been recorded,
which is fewer than in Central America and the Caribbean. One hundred ninety two
samples collected in 19 Mexican states from the Muséum national d’Histoire naturelle
(Paris) collection have been studied and 30 species identified. Four of them are the species
previously recorded (
U.
ambrosiae
,
U.
erigeronense
,
U.
pseudoambrosiae
and
U.
sonchi
). Fifteen
North American species are recorded for the first time from Mexico:
U.
astronomus
,
U.
brevitarsus
,
U.
chani
,
U.
eupatoricolens
,
U.
gravicorne
,
U.
macgillivrayae
,
U.
maximilianicola
,
U.
nigrotuberculatum
,
U.
obscuricaudatum
,
U.
paucosensoriatum
,
U.
penderum
,
U.
reynoldense
,
U.
richardsi
,
U.
stoetzelae
and
U.
zerogutierrezis
. Thirty-three new “aphid/host
plant” relationships of these species have been established. Comments about the distribution
of the species are made. Eleven new species are described, illustrated and discussed:
U.
penae
,
U.
mexicanum
,
U.
gnaphalii
,
U.
sinuense
,
U.
munozae
,
U.
zacatecense
,
U.
queretarense
,
U.
tlaxcalense
,
U
.
latgei
,
U.
heterothecae
and
U.
remaudiereorum
. An appendix with modifications
for 17 keys in Blackman and Eastop’s work, “Aphids on the World’s Herbaceous
Plants and Shrubs”, is presented and 3 additional keys are given
