Type material. Holotype: Female, Brazil, São Paulo, Campinas, on Tephrosia candida, 30/X/1934. Deposited in IB, type Nº 361 ( Hempel, 1937), not found. Part of the type series is in the USNM ( Miller and Gimpel, 2000), not studied.

Material examined. No data, but labelled Eriococcus campinensis Hempel , 9 adult females (4 in good condition) and 5 first-instar nymphs, IB.

Appearance in life. The female forms a thick, felted, non-sticky sac, with the rear end facing upwards and provided with a small circular hole. Some transverse striae are barely perceptible. The sac measures about 3 mm in length and 2.2 mm in width ( Hempel, 1937).

Species diagnosis. Microtubular ducts sparse, present only along margin on both surfaces; marginal setae differentiated from dorsal setae on abdominal segments; metacoxae with 6–10 dorsal pores; prothoracic tibia with 6 setae; anal lobes each with 3–4 ventral flagellate setae and a long, narrow inner anterior dorsal setae.
