Schizaphis minuta  (van der Goot) (Fig. 1) was found for the first time in the Western Hemisphere in suction trap samples in Florida. The first specimen was collected in a trap at Quincy (Gadsden County) for the period 16 - 23 November 1998. The record subsequently was verified by collections on several species of Cyperus in the Ft. Pierce area. The aphid is specific to Cyperus and is unlikely to pose any threat to agriculture. Schizaphis minuta probably is native to Asia and has been recorded previously in Africa and Australia. It is not known to be a pest

Schizaphis rninuta (van der Goot) (Hornoptera: Aphididae), 
new to the United States 
Schizaphis minuta (van der Goot) (Fig. 1) was 
found for the first time in the Western Hemisphere in 
suction trap samples in  Florida. The first specimen 
was collectedin a trap a t  Quincy (Gadsden County) for 
the period 16 - 23 November 1998. The record subse- 
quently was verified by collections on several species 
of Cyperus in the Ft. Pierce area. The aphid is specific 
to Cyperus and is unlikely to pose any threat to 
agriculture. Schizaphis minutaprobably is native to 
Asia and has been recorded previously in Africa and 
Australia. It is not known to be a pest. 
Schizaphis minuta can be identified using East- 
op7s (1961) key. It is most easily recognized by the 
characteristic asymmetrical siphunculi reminiscent 
of those found in Rhopalosiphum (Fig 2). The median 
vein of the wing is once-branched, as in other Schiza- 
phis. 
Specimens were found in suction trap samples in 
Quincy, Ft. Pierce (St. Lucie County), Belle Glade 
(Palm Beach County), Immokalee (Collier County), 
Kendall (Miami-Dade County), and Winter Haven 
(Polk County). Schizaphis minuta specimens were 
most common in the traps in Ft. Pierce and Immoka- 
lee. Only one specimen was collected in Kendall. 
Populations and flight activity are highest in the 
winter, when the plants are flowering. The aphids can 
be found most easily in the flower heads of Cyperus.
