Material studied. Paratypes. 2 adult females: France, Bouche-du-Rhône, Marseille, Mazargues, on Helianthemum polifolium (Cistaceae) , 16.v.1934, coll: L. Goux ( MNHN: 14763-2, 4, 5).

Description. Adult female. Body elongate oval, 1.40–2.20 mm long, 0.75–1.48 mm wide. Eyes marginal, 55–65 µm wide. Antenna 8 segmented, 360–380 µm long; apical segment 50–55 µm long, 25–35 µm wide; apical setae 35–40 µm long and 3 fleshy setae 30–35 µm long. Tentorium 185–195 µm long, 130–195 µm wide. Labium 145–155 µm long, 110–130 µm wide. Anterior spiracles 60 µm long, 30 µm wide across atrium; posterior spiracles 65 µm long, 35–37.5 µm wide. Legs well developed; posterior legs: trochanter + femur 195–250 µm long; tibia + tarsus 250–275 µm long; claw 20–25 µm long. Ratio of lengths of tibia + tarsus to trochanter + femur 1.11–1.28:1; ratio of lengths of tibia to tarsus 2.1–2.29:1; ratio of length of trochanter + femur to greatest width of femur 2.60–2.77:1. Tarsal digitules hair-like, each 20–25 µm long. Claw digitules knobbed, each 27.5–30.0 µm long. Anterior ostioles with a total for both lips of 16–21 trilocular pores and 2–4 setae; each posterior ostiole with a total for both lips of 22–29 trilocular pores and 4–6 setae. Anal ring 100–113 µm wide, with 6 setae, each seta 100–125 µm long. Cerarii slightly sclerotized, present on posterior 3 abdominal segments only; each anal lobe cerarius with 2 slender enlarged setae, 15–20 µm long, 1 smaller enlarged seta, 2 or 3 spine-like auxiliary setae, and 13–15 trilocular pores; other marginal cerarii each with 2 enlarged setae and several trilocular pores; dorsal cerarii absent.

Dorsum. Setae spine-like, each 5–15 µm long, distributed as usual. Clusters each with 0–2 (usually 1 or 2) multilocular disc pores, each pore 8–10 µm in diameter with 2 rings of loculi, a small oral collar tubular duct, 9–10 µm long, 2–3 µm wide, 1 or 3 large oral collar tubular ducts, each 9–10 µm long, 3–5 µm wide and 0–2 minute discoidal pores, each 2.0–2.5 µm in diameter; clusters present on thorax and head, and also on abdominal segments as follows: I 15–29, II 14–18, III 16, IV 11–27, V 16 or 17, VI 9 or 10, VII 6–11, VIII absent. Trilocular pores, each 4–5 µm in diameter, scattered throughout. Minute discoidal pores mainly restricted to within clusters.

Venter. Setae of 2 types: (i) relatively short, slender hair-like setae, each 15–55 µm long; longest setae medially on head; and (ii) spine-like setae, each 10–13 µm long, in submarginal rows. Apical setae of anal lobe all broken. Multilocular disc pores of 2 kinds: (i) pores, each 8–10 µm in diameter with only a single ring of loculi, in a single row on abdominal segments as follows: IV 0– 12, V 29–31, VI 52 –92, VII 97 –114, VIII + IX 49 –60, and (ii) pores, each 8–10 µm in diameter with 2 rings of loculi, restricted to clusters as on dorsum; each cluster with 1–3 (usually 2) multilocular disc pores, a single small oral collar tubular duct, each 9–10 µm long, 2–3 µm wide in centre, 0–3 large oral collar tubular ducts, each 9–10 µm long, 3–5 µm wide, plus 0–2 minute discoidal pores, each 2.0–2.5 µm in diameter; present in submarginal clusters and medially in abdominal segments II–IV. Quinquelocular pores, each 5–6 µm in diameter, present medially on head, thorax and abdominal segments I–V. Trilocular pores, each 3–4 µm in diameter, scattered throughout except absent medially on head and thorax. Minute discoidal pores, each 2 µm in diameter, few. Oral collar tubular ducts of 3 sizes: largest and smallest ducts restricted to clusters as on dorsum; medium-sized ducts, each 8–10 µm long, 2.5–5.0 µm wide, restricted to body margins and in single rows on abdominal segments as follows: IV 18–21, V 90 –93, VI 73 –77, VII 42 –61, VIII + IX 25–31.

Comments. Pelionella sablia is most similar to P. grassiana and P. proeminens in lacking a circulus but differs in having fewer than 4 pairs of marginal cerarii (14–17 pairs in the other two species). P. s ab l i a is also similar to P. glandulifer and P. kansui in having fewer than 7 marginal pairs of cerarii but differs in having: (i) quinquelocular pores throughout most of venter (restricted to around mouthparts in P. glandulifera , absent in P. k a ns u i) and (ii) no circulus (present in both of the other species).

Danzig & Gavrilov-Zimin (2014) used the name " Pelionella sablia " before the genus name was made available in the present work. Refer to Comments under the genus Pelionella above for further information. Danzig & Gavrilov-Zimin (2014) listed “ Pelionella sablia ” citing “Kaydan 2014?”, without suggesting that this was a new combination. Here the new combination is made available in a manner that satisfies the requirements on the Code (ICZN, 1999). Danzig & Gavrilov-Zimin (2014) also reproduced Fig. 17 with minor modification as their figure 2.1.3-30.

Host plants. On Helianthemum polifolium (Cistaceae) .

Distribution. France (Marseille).
