Tarsal digitules hair-like, each 20–25 µm long. Claw digitules knobbed, each about 27.5 µm long. Anterior ostioles with a total for both lips of 26–34 trilocular pores and 7–10 setae; posterior ostioles with a total for both lips of 33–45 trilocular pores and 4–8 setae. Anal ring 85–95 µm wide, with 6 setae, each seta 95–120 µm long. Cerarii numbering 2–6 marginal pairs, anal lobe cerari sclerotized, each with 2 slender enlarged setae, 20–28 µm long, 2 spine-like auxiliary setae and 13–22 trilocular pores; other marginal cerarii each with 2 enlarged setae and several trilocular pores. Dorsal cerarii absent.

Dorsum. Setae spine-like, each 5.0–17.5 µm long, in transverse lines. Clusters each with 1–5 (usually 2) multilocular disc pores, each 7.5–8.0 µm in diameter; each cluster with a small oral collar tubular duct in centre, 7.5–8.0 µm long, 3.0–4.0 µm wide, 1–4 large ducts, each 10 µm long, 5–6 µm wide, and 1–4 minute discoidal pores, each 2–3 µm in diameter; clusters totalling 25–58 clusters on head and thorax, and also on abdominal segments as follows: I 7–10, II 5–10, III 7–11, IV 7– 11, V 8–11, VI 6, VII 6–9, 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 15–85 µm long, longest setae medially on head; and (ii) spine-like setae, each 7.5–20 µm long, in submarginal rows. Apical setae on anal lobes 155–205 µm long. Multilocular disc pores of 2 kinds: (i) pores, each 7.5–9.0 µm in diameter with only a single ring of loculi, present in single rows on abdominal segments as follows: IV 15, V 13–25, VI 35 –45, VII 49 –71, VIII + IX 19–48; and (ii) pores, each 7.5–8.0 µm in diameter with 2 rings of 11 loculi, similar to those on dorsum,in clusters; each cluster with 1–4 disc pores, a single small oral collar tubular duct 7.5 µm long, 3.0–4.0 µm wide, in centre, plus 1–4 large ducts, each 10 µm long, 5–6 µm wide, present among multilocular disc pores, and 1–3 minute discoidal pores, each 2–3 µm in diameter; clusters all in submarginal area. Quinquelocular pores absent. Trilocular pores, each 3–4 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 on dorsum; medium-sized ducts, each 10–11 µm long, 3.0–4.0 µm wide, present in abdominal segments as follows: II-III 25–48, IV 32 –51, V 63 –83, VI 51 –82, VII 38 –53, VIII+ IX 35 –45; medium sized ducts concentrated on body margin and in single rows on abdominal segments.

Comments. Pelionella kansui Kaydan can be readily distinguished from other species in the genus in having the following combination of features: (i) 2 sizes of oral collar tubular ducts in each cluster on dorsum; (ii) each dorsal cluster with 1–5 (usually 2) multilocular disc pores, each with 2 rings of 11 loculi; and (iii) no quinquelocular pores on venter. Pelionella kansui is most similar to P. manifecta in having 2 of sizes oral collar tubular duct on the dorsum but it differs in having: (i) no quinquelocular pores on the venter, and (ii) in having fewer than 7 marginal cerarii. Pellionella kansui is also similar to P. glandulifer but differs in having (characters for P. glandulifer in brackets): (i) clusters on dorsum with 1–5 multilocular disc pores (0–2, generally 0 in clusters on posterior abdominal segments), (ii) no quinquelocular pores on venter (a few around mouthparts) and (iii) multilocular disc pores in a compact band on dorsum of abdominal segment VII (few or none on dorsum of abdominal segment VII).

Danzig & Gavrilov-Zimin (2014) used the name " Pelionella kansui " 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. 12 with minor modification (the illustration of multilocular disc pores) as their figure 2.1.3-27.

The type specimens were restricted to those collected on E. seguieriana even though there is great similarity between specimens collected on E. seguieriana and other host plants. Only the type specimens were used for the measurements.

Etymology. This species is named after Professor Dr. İbrahim Akif Kansu (Ankara University, Agriculture Faculty, Plant Protection Department, Ankara, Turkey) who has made important contributions to the study of entomology in Turkey over a period of more than 50 years.

Host plants. On roots of Salvia sp., S. multicaulis (Lamiaceae) , Euphorbia seguieriana (Euphorbiaceae) , and Verbascum sp. (Scrophulariaceae).

Distribution. Turkey. This species was collected generally above 1500 m altitude in Eastern Turkey (Bitlis, Erzurum, Hakkari and Van).
