Diagnosis. A small species with very characteristic triangular aperture shape, "reversely oblique" peristome and flat whorls.
Description. Shell light greyish-yellowish, slender turriform; 7–7.75 (n=2) whorls are flattened, but are separated by rather deep suture; protoconch region was corroded in the available shells; the only visible trait was that the first whorl was not ribbed; teleoconch regularly, finely ribbed; ribs are widely spaced and rather irregular on the last two whorls, their shape is slightly wavy; the last quarter of whorl is with one to two ribs; ribs relatively strong, with fine spiral structure between the ribs on the whole teleoconch; aperture almost triangular, "reversely oblique" from lateral view (upper end is situated posteriorly, basal end anteriorly); parietal part is straight; apertural rim thickened and reflexed, the boundary between the two circles of the rim is hardly visible.
Measurements (in mm). H: 6.1–6.3, D: 3.0–3.2 (n=2).
Differential diagnosis. P. abletti n. sp. differs from P. harli n. sp., P. himalayae, P. sophiae n. sp. by the flatter whorls, triangular aperture and the more widely spaced ribs (especially on the neck region), with usually strong spiral lines inbetween. Moreover, from lateral view the apertural margin of P. abletti n. sp. is strongly oblique. See also under P. siyomensis and Table 5.
Material. Himalaya, Darjiling, coll. W. Blanford, NHMUK 1860.6.27.32.3 (holotype), NHMUK 1860.6.27.32.4 (1 paratype) (mixed sample with P. himalayae); India, NHMUK 20130409.3 (1 paratype) (mixed sample with P. himalayae); Toruputu Peak, 500, Dafla, NHMUK 1903.7.1.3746.9/1 (with weaker spiral lines, not paratype); Indien, Dr. Stoliczka coll, 1880, NHMW 109196 (1 paratype; mixed sample with P. prestoni n. sp.: NHMW 109194 and P. h i m al ay a e: NHMW 109195); Darjiling, Indien, Oberwimmer coll, NHMW 109197 (1 paratype; mixed sample with P. himalayae: NHMW 66304); Darjeeling, leg. Stoliczka, 1870, NHMUK 109198/1; Darjiling, coll Ehrmann ex Sowerby + Fulton, SMF 342541 (mixed sample with P. himalayae: SMF 109828).
Type locality. Himalaya, Darjiling.
Etymology. The new species is dedicated to Jonathan Ablett (NHM), the friend of the first author, for his boundless help during this and other taxonomic revisions.
Distribution. Most samples were collected near Darjiling, one sample is labelled as being collected from Toruputu Peak (Dafla Hills) (see also Fig. 2 and Table 3).
Remarks. In museum collections all specimens of this species were in mixed lots with Pseudopomatias himalayae.
