Willinkcol. ( IFML).  Paratypes: 3 adultfemales with the same data as the holotype.   Additional material examined. Argentina, Tucumán, San Miguel de Tucumán( 26° 49′ 0″ S, 65° 13′ 0″ W), on “tatané”  Chloroleucon tenuiflorum, -/5/2015, Claps& Morenocol., 2(5); on “churqui”  Acacia caven, same date and collector, 2(4) ( IFML).   Diagnosis. Slide-mounted adult female with abundant dorsal conical setae in transverse lines on abdominal and thoracic segments; symmetrical macrotubular ducts; numerous microtubular ducts of typeB on both surfaces; marginal setae undifferentiated from dorsal setae; metacoxa each with approximately 50 pores, 30 on dorsal surface and 20 on ventral surface; anal lobes with 2 ventral setae ( González & Claps 2011).  Observations.Severe attacks have been noted on urban trees of  Chloroleucon tenuiflorum( Fig. 5), an unusual phenomenon among eriococcids in Argentina. Such attacks can damage hosts.   Distribution. Argentina, Neotropical region, Chacosubregion, Chaco province. 1434654816 1993-11-06 IFML M. C. G.
