Ferrisia multiformis Granara de Willink, 1991 a: 181 .

This species was described and illustrated by Granara de Willink (1991) from Parthenium (Asteraceae) in Argentina based on the holotype and 10 paratype adult females (housed in IMLA, BMNH and USNM). We found no specimens of this species among the unidentified South American material that we examined. We examined the two paratype specimens housed in the USNM and noted the following diagnostic features: both pairs of ostioles are present, multilocular disc pores are present only posterior to the vulva, the dorsal enlarged tubular ducts never number more than two, the hind trochanter + femur is less than 300 µm long, with a ratio of hind trochanter + femur to tibia + tarsus of about 1.1, and the antennae are each about 400 µm long .

We have modified the original illustration of the adult female of this species ( Fig. 15) based on examination of the paratypes in the USNM. The original drawing showed oral-collar tubular ducts dorsally, but this appears to be an error, possibly resulting from interpreting large discoidal pores as the openings of ducts.
