Corandesia kozári Foldi n. sp.

Materiel examined. Holotype adult female. VENEZUELA: Merida, Cordillera de los Andes, páramo of Piedras Blancas, 4200 m, 6.xi.1984, on dead leaves of Espeletia timotensis (Asteracae) , I. Foldi coll., MNHN. Paratypes: same data as holotype: 2 adult females, MNHN.

ADULT FEMALE ( Fig. 1 )

Description based on 3 adult females in fair condition.

Mounted material. Body 5.3–6.5 mm long, broadest across abdomen, width 4–4.7 mm (Holotype 6.1 mm long, 4.2 mm wide). Characters as for generic diagnosis.

Dorsum. Derm rather thick. Dorsal surface with abundant multilocular pores of 3 types, each with a thickened rim: (i) multilocular pores ( Fig. 1 F), each 10–12 µm in diameter, with about 9 triangular shaped outer loculi plus 2 circular inner loculi in an oval-shaped sunken centre; frequent throughout and fairly evenly distributed; (ii) multilocular pores ( Fig. 1 C) with about 12 outer loculi plus 2 small inner loculi in an ovalshaped centre, distributed on head and thorax and in a transverse row, 1 pore wide, on abdomen; (iii) multilocular pores ( Fig. 1 J), each 11–13 µm wide, with 3 inner loculi in a triangular centre plus about 12 outer loculi; sparsely present throughout. Dorsal setae variable: (i) stout hair-like setae ( Fig. 1 B) most common type, stright or curved, each 35–90 µm long, evenly distributed on head and thorax, but in rows 1 seta wide across all abdominal segments; (ii) longest hair-like setae ( Fig. 1 E) with large conspicuous collars (collared setae), each 70–170 µm long, scattered medially on head and thorax, otherwise sparsely present on margin, anteriorly on head and particularly on posterior end of body; (iii) slender flagellate setae ( Fig. 1 O), each 30–40 µm long, sparse throughout, and (iv) hairs ( Fig. 1 D), each 30–35 µm long, sparsely scattered throughout. Anal opening surrounded by a group of flagellate setae ( Fig. 1 H), each 40–90 µm long and by numerous multilocular pores, each mainly with an oval-shaped centre with 2 small inner loculi and 9–14 outer loculi ( Fig. 1 F). Anal tube ( Fig. 1 G) 90 µm long, with a ring of polygonal pores at inner end.

Venter. Derm membranous. Multilocular pores, each 10–12 µm in diameter, with a thickened rim and a large round, oval, triangular, or (rarely) quadrate centre with 2, 3 or 4 inner loculi and 10–16 outer loculi ( Fig. 1 J); present throughout. Multilocular pores ( Fig. 1 R) with thickened rim, with a triangular centre with 3 inner loculi plus 3x 2 elongate outer loculi; sparsely distributed on head and thorax. Setal types as on dorsum, present throughout but most frequent on head and thorax, and along submargin of body; less frequent on midthorax, and abdomen apart from around vulva and posterior end of abdomen: slender flagellate setae ( Fig. 1 O), each 30–40 µm long, weakly scattered throughout; stout hair-like setae ( Fig. 1 E), each 40–100 µm long, scattered on all body segments, and in transverse rows 1 seta wide on abdominal segments; longest hair-like setae, each 140–170 µm, on margin, and medially on head and thorax; hairs ( Fig. 1 D), each 30–35 µm long, scattered throughout; spiniform setae ( Fig. 1 B), rare, each 15–35 µm long, scattered, most frequent on margin and submargin of abdomen. Spinules ( Fig. 1 M), each mostly with 2 or 3 sharply pointed tips, present medially and submedially, extending from metathorax to vulvar area on abdomen.

Antennae 7 segmented, each 520–580 µm long; all antennal segments with hair-like setae, each 30–75 µm long; segment III also with 2 short setae, 7–8 µm long; segments III–VI each with 2 or 3 fleshy setae, each 40– 60 µm long; apical segment ( Fig. 1 A) 120 µm long, 60 µm wide, with about 6–8 hair-like setae, a single long apical seta 260 µm long, plus 4–6 fleshy setae and 2 small sensory organs at apex. Eyespots each 95–110 µm wide, lens 40 µm in diameter, located near antennal base. Mouthparts present; tentorium easily discernable, labium apparently 2 segmented, about 330 µm long; apical segment with about 10 short setae, each 25–35 µm long, one paratype without stylets. Mesothoracic spiracles ( Fig. 1 P) each with atrium 90–110 µm wide, with about 17–21 multilocular pores; each pore with a bilocular centre and 9–12 outer loculi; spiracular apodeme 125–140 µm long. Metathoracic spiracles each with atrium 90–120 µm wide, with about 17–26 atrial multilocular pores; each pore and spiracular apodeme as for mesothoracic spiracles. Abdominal spiracles ( Fig. 1 K) in 5 pairs, present on abdominal segments IV–VIII, small, each peritreme 10–12 µm wide, with a strongly sclerotised atrium about 25–30 µm long, 15–18 µm wide; without pores; each atrium opening into a narrow, small sclerotised tube leading to tracheae. Legs well developed; metathoracic legs: coxa 120–140µm long, 210–225 µm wide, with about 5–8 setae on ventral surface near articulation with trochanter, each seta 65–100 µm long; trochanter + femur 460–480 µm long, each trochanter with a long distal trochanteral seta 185–200 µm long, and with 3 or 4 campaniform pores on each face; tibia 400–420 µm long, with setae along ventral margin and spur-like setae on distal part, each 25–70 µm long; tarsus 210–215 µm long, with a few hair-like setae on ventral margin and spur-like setae distally, each 25–50 µm long, tarsal digitules short, acute; claw each 70–80 µm long, without a denticle; claw digitules acute, both shorter than claw, each 30–35 µm long. Vulvar opening a transverse fissure, 190–225 µm wide. Cicatrices three ( Fig. 1 I), each with small polygonal markings on surface, arranged in a semi-circle posterior to vulva, median cicatrice largest, elongate, 180–360 µm long, 130–170 µm wide; lateral cicatrices irregular in shape, each 140–220 µm long, 105–150 µm wide. Ventral surface with sclerotised dermal patches ( Fig. 1 L) in transverse rows submedially.

Derivatio nominis. The new species “ kozári ” is named in honour of Dr. Ferenc Kozár (Plant Protection Institute, Budapest, Hungary) for his remarkable contribution to the study of the scale insect fauna of the world.
