Lecanopsis salvatorei Pellizzari n. sp.

( Fig. 5 )

Type material. Holotype: adult female, Italy, Basilicata region, Laurenzana (Potenza), 1300m asl, 26.x.1993, leg. S. Marotta, slide n. 1700/1. Paratypes: 5 adult females, same data as holotype, slides n. 1700/2–7.

Adult female

Unmounted female: not seen.

Mounted specimens: elongate oval, 3 mm (2.2–3.6) long, 1.5 mm (1–1.7) wide.

Venter: derm membranous, with signs of segmentation on thorax and abdomen; dermal spinules present medially on all thoracic and abdominal segments. Antennae 8 segmented; length of segments in µm: I 50 (44–60); II 30 μ (28–34); III 63 (54–70); IV 36 (28–46); V 33 (30–36); VI 27 (26–30); VII 26 (22–30) and VIII 36 (30–40). Scape and segment II each with 2 setae, III without setae, IV without setae or with 1 hair-like seta, V with 2 hairlike setae, VI with 1 fleshy seta, VII with 1 fleshy setae + 1 hair-like seta, and VIII with 3 fleshy setae + 4 or 5 hairlike setae. Legs well developed, stout. Tibio-tarsal sclerosis present. Measurements of hind leg: coxa 116 (100–125) µm long; trochanter + femur 225 (200–250); tibia 198 (175–215) long, 47 wide (length to width ratio 4.2:1); tarsus 89 (80–100) µm; claw digitules broad, longer than claw; tarsal digitules thin, longer than claw, capitate, each about 40 µm long. Spiracles with peritreme 40–42 µm wide; peritreme cavity round, large, 75 (70–80) µm wide, each peritreme cavity with 30–35 spiracular disc pores. Spiracular disc pores, each 5–6 µm wide with 3–8 loculi (mostly 8): with 39 (32–51) pores either forming a loose group or a sparse band reaching body margin near each anterior spiracle; spiracular disc pores usually absent near posterior spiracle (3 specimens each with one pore). Simple pores scattered but absent medially. Pregenital disc pores each 6–8 µm wide with 5–7 loculi (mostly with 7), distributed mostly around genital opening, scarce on posterior IV–VII pregenital segments. Very small simple pores, each 1.6 µm wide, scattered, especially numerous medially and submedially on thoracic segments. Ventral tubular ducts of two sizes: small ducts each 16–20 µm long, 5 µm wide; large ducts each 25 (22–29) long, 8 µm wide, both ducts frequent on abdomen, less frequent on thorax, rare on head. Small simple pores sparse. Body setae very small, spinose, each about 5–8 µm long; with two pairs of interantennal setae, longer pair each 35 (30–40) µm long, shorter pair 12–16 µm long; also with 3 or 4 very small setae, about 6 µm long on frons. With an irregular submarginal row of small bent setae, each 16–20 µm long, distributed around body submargin. With a pair of pregenital setae present medially on posterior 4 or 5 abdominal segments, most posterior setae 54 (48–60) µm long, other pairs clearly smaller, variable in length, each 14–30 µm. Stylet loop reaching mesocoxae.

Dorsum: derm membranous. Preopercular pores each 6–10 µm wide, distributed in a longitudinal band, with maximum width 6–8 pores, narrower than space between coxae, extending from anal plates to mesothorax inclusive. Marginal setae of various sizes, bent: setae on head each 33 (30–40) µm long; setae on thorax and abdomen smaller, each 17 (13–20) µm long and those on anal lobes each 24 (20–32) µm long. Dorsal setae sparse, mostly 10–12 µm long but up to 16 µm. Dorsal tubular ducts sparse on abdomen, rare on thorax and head. Darkrimmed simple pores, each about 5 µm wide, numerous throughout dorsum. Anal ring round, with 8 setae, each 110–130 µm long; anal plates together quadrate, with rounded outer angles, each plate 150 µm long and 75 µm wide.

Etymology. This species is dedicated to the memory of the well-known coccidologist Salvatore Marotta, who collected and mounted this new species.

Host plant. Off roots of Festuca (Poaceae) . According to the label data, the adult females of this species were collected in late October at 1300m asl, suggesting that this should be the overwintering stage.

Distribution. Southern Italy (Basilicata Region).

Comments. Adult female L. salvatorei have numerous ventral tubular ducts and large peritreme cavities, each with 30+ disc pores, as in the genus Lecanopsis . But, L. salvatorei has a pair of pregenital setae medially on the posterior 4 or 5 abdominal segments (as in Hadzibejliaspis ). No first instar nymphs are available.
