Erimococcus ozani ; Danzig & Gavrilov-Zimin 2014: 397. Unavailable name.

Material studied. Holotype and 3 paratype adult females: Turkey, Iğdır-Aralık-Nahcivan road, N: 39°57’348’’, E: 044°07’460’’, 853 m, on Suaeda sp. ( Amaranthaceae ), 12.vi.2007, coll: M. Bora Kaydan ( KPCT: 3588), on a single slide. Holotype specimen nearest to name label, marked by black pen on the right side underneath specimen.

Description. Adult female. Body elongate oval, 1.54–1.64 mm long, 0.88–0.98 mm wide. Eye marginal, 35–50 µm wide. Antenna 8 segmented, 380–400 µm long; apical segment 60–65 µm long, 20.0–27.5 µm wide, with apical setae 27–46 µm long plus 3 fleshy setae, each 22–30 µm long. Tentorium 145–150 µm long, 160–170 µm wide. Labium 145–155 µm long, 100–130 µm wide. Anterior spiracles 65–75 µm long, 35–43 µm wide across atrium; posterior spiracles 85–95 µm long, 45–50 µm wide across atrium. Circulus large, oval, between abdominal segments III and IV, 200–225 µm wide. Legs well developed; length data for posterior legs: coxa 100–150 µm, trochanter + femur 225–250 µm, tibia + tarsus 270–290 µm, claw 25–30 µm. Ratio of lengths of tibia + tarsus to trochanter + femur 1.16–1.25:1; ratio of lengths of tibia to tarsus 2.00–2.08:1; ratio of length of hind trochanter + femur to greatest width of femur 3.00–3.57:1. Tarsal digitules each 22–30 µm long, hair-like. Claw digitules knobbed, each 25–30 µm long. Anterior ostioles each with a total for both lips of 25–33 trilocular pores and 4–7 setae; posterior ostioles each with a total for both lips of 30–42 trilocular pores and 10–12 setae. Anal ring 90–95 µm wide, with 6 setae, each seta 100–120 µm long. Cerarii 2 pairs only, each slightly sclerotized; anal lobe cerarii each with 2 slender enlarged setae, 20–25 µm long, plus 14–18 trilocular pores and 3 or 4 spine-like auxiliary setae; cerarius on abdominal segment VII with 2 slender enlarged setae and 6–10 trilocular pores; other segments usually with 1 or 2 long, robust marginal setae on each side in position of cerarii. Dorsal cerarii absent.

Dorsum. Body setae spine-like, each 7.5–15.0 µm long. Clusters each with 2 oral collar tubular ducts, each cluster with 1 large duct, 9–10 µm long, 6 µm wide, and 1 smaller duct, each 7–8 µm long, 3 µm wide; clusters present sparsely on head, becoming more abundant and in irregular rows on thorax and abdominal segments (except absent on last abdominal segment); distributed on abdomen as follows: segment I 13–15, II 15–19, III 17– 19, IV 21–23, V 24– 26, VI 26–31, and VII 11–15. Trilocular pores, each 2.5–3.0 µm in diameter, scattered over entire body. Minute discoidal pores, each 2 µm in diameter, generally associated with clusters, but also scattered throughout.

Venter. Setae of 2 types: (i) slender hair-like setae, each 12–100 µm long, longest setae medially on head; and (ii) spine-like setae, each 10–15 µm long, present in 2 or 3 submarginal rows. Apical setae of anal lobe each 175–198 µm long. Multilocular disc pores in rows on abdominal segments as follows: II+III 0–4, IV 12–14, V 12–16, VI 20–34, VII 42 –49, VIII + IX 19–25; each pore 7.5–10.0 µm in diameter. Quinquelocular pores absent. Trilocular pores and minute discoidal pores scattered throughout. Oral collar tubular ducts concentrated on body margin and in single rows across all abdominal segments, of 3 sizes: largest and smallest ducts in submarginal pairs similar to those on dorsum; and medium-sized ducts, each 7–9 µm long, 3 µm wide, few on mid thorax and abdominal segments as follows: II + III 16–34 ducts, IV 20–30, V 29–35, VI 23– 28, VII 20–27, VIII + IX 13–15.

Comments. E. ozani is closest to E. limoniastri and E. talhouki in having: (i) few cerarii, and (ii) pairs of oral collar tubular ducts on the dorsum, each pair with 1 large and 1 small duct. However, E. ozani can be readily distinguished from these and all other species in the genus in lacking: (i) multilocular disc pores on the dorsum (as in E. multitubulatus ); and (ii) quinquelocular pores on the venter.

Danzig & Gavrilov-Zimin (2014) used the name " Erimococcus ozani " before it was made available in the present work. According to Article 16 (specifically 16.1 and 16.4) of the ICZN (1999), this name must be considered unavailable from their work. Here the name is published in a way that meets the criteria of availability as specified by the ICZN (1999). Danzig & Gavrilov-Zimin (2014) also used Fig. 3 as their figure 2.1.3-4.

Etymology. This species is named after the son of the author, Evrim Ozan KAYDAN, who suffers a lot due to the absence of his father studying scale insects.

Host plants. Suaeda sp. ( Amaranthaceae ).

Distribution. Turkey (Iğdır).
