description: Eriococcus paranaensis Foldi & Kozár sp. nov.   
 Type material. Holotype, adult female on right side, marked, plus one paratype adult female on left side of same slide: Brazil, Paraná, Curitiba, on Baccharis dracunculifolia (Compositae), 14-XI-1984, I. Foldi coll., (N° 10156–1 right side) in MNHN.   
 Paratypes: same data as holotype, 3 adult females: 2 (N° 10156–1 (on left side of holotype slide), plus 10156–3) in MNHN; one (N° 10156-2) in PPI.   
ADULT FEMALE (Fig. 4) described from 4 specimens  
 Mounted female. Body elongate oval, 2.15–2.25 mm long, 1.50–1.60 mm wide. Antenna 7 segmented, each 197–219 µm long; most segments with few long hair-like setae but segment III without setae; segment lengths (µm): I 32–36, II 28–31, III 42–46, IV 37–40, V 14–16, VI 16–18 and VII 28–32; segment II with a sensory pore; apical segment with apical seta 55 µm long, plus 3 sensory falcate setae, longest 32 µm; two preapical segments with a falcate sensory seta 16–21 µm long. Frontal lobes present. Eyes situated near margin on venter.   
 Vente r. Labium three-segmented, 127–135 µm long. Legs long, well developed. Prothoracic leg (lengths in µm): coxa 82–86, trochanter 79, femur 139, tibia 103, tarsus 117, claw 42 µm. Mesothoracic legs (lengths in µm): coxa: 82–84, trochanter + femur 210–220, tibia 112–115, tarsus 115–120, claw 39–43. Prothoracic legs (lengths in µm): coxae 84–89, trochanter + femur 220–230, tibia 127–135, tarsus 125–135, tarsal digitules knobbed, each about 45 µm long, claw 45–47, claw digitules each about 51 long, slightly knobbed; coxae with rows of microspines; metacoxae with 8–11 large translucent pores; femur with about 2–4 translucent pores on distal part; trochanter with 2 sensory pores on each side, and a short seta 36 µm long plus a long seta 110 µm long; claw with a denticle; legs with few hair-like setae, each 20–30 µm long.   
Disc pores abundant, each with 3–7 loculi and 5 µm in diameter, distributed in bands on all abdominal and thoracic segments plus a few on head. Peritreme of anterior spiracles each 50 µm wide. Ventral hair-like setae scattered, length variable, each 20–90 µm long; also with 2–4 long setae on head medially. Microtubular duct absent. Macrotubular ducts each 4 µm wide, 35 µm long, sparsely distributed throughout. Cruciform pores each 5 µm wide; distributed in a submarginal band but absent from posterior abdominal segments VI–VIII. Anal lobes sclerotised, each with 3 hair-like setae.  
 Margin. Margin with a few spinose setae, but these absent from posterior 3 abdominal segments.   
 Dorsum. Dorsal spinose setae of varying size, each 19–35 µm long, in transverse segmental rows 2–3 setae wide. Microtubular ducts each 5 µm long with a cruciform opening, sparsely scattered among dorsal spinose setae, and also in 6 distinct groups submedially, with one group on mesothorax, one on metathorax and one on each of anterior 4 abdominal segments. Macrotubular ducts of two sizes: smaller ducts each 3–4 µm wide, 30–35 µm, in 8 groups submedially, surrounding groups of microtubular ducts on meso- and metathorax and on abdominal segments I to IV; larger ducts each 5–6 µm wide and 40–45 µm long, distributed along margin and submargin, sparse on all segments. Disc pores absent. Anal ring with pores and with 8 hair-like setae, each 101–110 µm long. Anal lobes sclerotised, as long as wide, each with 2 spinose setae along inner margin and 1 seta on outer margin; apical anal lobe setae each about 245–255 µm long. Suranal setae hairlike. Median sclerotised plate absent.   
 Etymology. The species is named after the State (Paraná) in Brazil in which it was collected.   
 Distribution and Host plants. Brazil, Paraná: Baccharis dracunculifolia (Compositae).   
 Comment E. paranaensis is similar to E. mendozae (Morrison, 1919) and E. leguminicola (Morrison, 1919) in sharing groups of microtubular ducts on the dorsal segments, in having large pores on the posterior coxae and in the presence of numerous cruciform pores on venter. However, E. paranaensis differs from both of the latter two species in having the groups of microtubular ducts surrounded by macrotubular ducts on the dorsum. E. paranaensis also differs from E. mendozae in having only about 10 coxal pores whereas E. mendozae has more than 20; and E. paranaensis differs from E. leguminicola in the absence of cruciform pores on posterior abdominal segments of the venter, in having frontal lobes (rather than frontal tubercles as on E. leguminicola), in the greater number of dorsal setae and in having only 5-locular disc pores (E. leguminicola has 4-, 5- and 8-locular disc pores).
