Tarsal digitules hair-like, each 25–40 µm long. Claw digitules knobbed, each 27–30 µm long. Anterior ostioles with a total for both lips of 12–40 trilocular pores and 6–9 setae; each posterior ostiole with a total for both lips of 23–50 trilocular pores and 7–12 setae. Anal ring 87–100 µm wide, with 6 setae, each seta 125–163 µm long. Cerarii slightly sclerotized, numbering 18 marginal pairs; anal lobe cerarii each with 2 slender enlarged setae, 17–30 µm long, 2 or 3 spine-like auxiliary setae and 11–19 trilocular pores; other marginal cerarii each with 2 slender enlarged setae and a few trilocular pores; dorsal cerarii absent.

Dorsum. Setae spine-like, each 5.0–15.0 µm long. Clusters each with 5–16 (usually 8–10) multilocular disc pores, each disc pore 6–10 µm in diameter, with 2 rings of loculi; each cluster with a small oral collar tubular duct, 7.5–10.0 µm long, 3.0–4.0 µm wide, 5–13 large tubular duct, each 10 µm long, 4–6 µm wide, plus 7–9 minute discoidal pores, each 2–3 µm in diameter; clusters on head and thorax, and also on abdominal segments as follows: I 6–9, II 6–9, III 7–12, IV 8– 10, V 8–10, VI 4–7, VII 5–10, VIII+IX 0. Trilocular pores, each 4–5 µm in diameter, scattered throughout. Minute discoidal pores mainly restricted to within clusters.

Venter. Setae of 2 types: (i) slender hair-like setae, each 12.5–135 µm long; longest setae medially on head; and (ii) spine-like setae, each 5–10 µm long, in submarginal rows. Apical setae of anal lobes 205–220 µm long. Multilocular disc pores of 2 kinds: (i) pores, each 7.5–10.0 µm in diameter with a single ring of loculi, present on abdominal segments as follows: V 1–4, VI 11–34, VII 52 –63, VIII+ IX 30–46; and (ii) pores, each 6–10 µm in diameter with 2 rings of loculi similar to those on dorsum; in clusters, each cluster with 8–10 disc pores, a single small tubular duct, 7.5–10.0 µm long, 3.0–4.0 µm wide in centre, and 5–13 large tubular ducts, each 10 µm long, 4–6 µm wide, plus 7–9 minute discoidal pores, each 2–3 µm in diameter; clusters restricted to submarginal areas.Quinquelocular pores, each 5–7 µm in diameter, sparse, restricted to around mouthparts, on thorax and first abdominal segments. Trilocular pores, each 4–5 µm in diameter, scattered throughout. Minute discoidal pores, each 2 µm in diameter, few. Oral collar tubular ducts of 3 sizes: largest and smallest ducts in clusters as described for dorsum; medium-sized ducts, each 10–13 µm long, 4–5 µm wide, present on body margins and in single rows on abdominal segments as follows: IV 2–4, V 63 –74, VI 48 –69, VII 26–42, VIII + IX 30–41.

Comments. Pelionella multipora can be readily distinguished from other Pelionella species in having the following combination of features: (i) 2 sizes of oral collar tubular ducts in each cluster; (ii) each dorsal cluster with 5–16 (usually 8–10) multilocular disc pores; and (iii) few quinquelocular pores on venter. Pelionella multipora is most similar to P. manifecta in having 2 sizes of oral collar tubular duct on dorsum, but differs in having many more multilocular disc pores in each cluster (only 2–6 in P. manifecta ). P. multipora is also similar to P. ba l t e at a and P. cycliger in having some dorsal clusters with 5 or more multilocular disc pores, but differs from both species in having 2 sizes of oral collar tubular duct in each cluster ( P. balteata and P. cycliger have only 1 small oral collar tubular duct in each cluster).

Only the type specimens were used for measurements.

Danzig & Gavrilov-Zimin (2014) used the name " Pelionella multipora " 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 reproduced Fig. 15 with minor modification (the illustration of multilocular disc pores) as their figure 2.1.3-29.

Etymology. The name of this species, “ multipora ”, refers to the large number of multilocular disc pores in each cluster.

Host plants. Roots of Salvia sp. ( Lamiaceae ) and Elytrigia repens (Poaceae) and some undetermined plant species.

Distribution. Turkey (Diyarbakır, Van).
