Acanthococcus gracielae González & Claps

Acanthococcus gracielae González & Claps 2011: 267 –268.

Material examined. Holotype: Argentina, Salta, Río Colorado (24°48'0″ S, 62°27'0″ W), unknown host, 6/XI/ 1993, M.C.G. Willink col. ( IFML) . Paratypes: 3 adult females 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 & Moreno col., 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 type B 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, Chaco subregion, Chaco province.
