New diagnosis
Shell ovate-conic, yellowish, with pyriform aperture; protoconch microsculpture wrinkled; central radular tooth formula 5–C–5/(2)1–1(2); pyriform bursa copulatrix, with a duct longer than bursa; one small pyriform seminal receptacle with no distinct duct; penis gradually tapering and simple, with distal end tapered and grayish pigmented; nervous system elongated (mean RPG ratio = 0.52) with slight black pigmentation.

Paratypes
IRAN: ZMH 51403 (5 ex.) and P. Glöeris (46 ex.) collection.
Type locality

Description
Shell ovate-conic with 4–4.5 whorls, height 2.5–4.4 mm (Fig. 6 A–C, Table 2); periostracum yellowish; protoconch approximately 350 µm wide with 1.25 whorls and nucleus around 120 µm long; protoconch microsculpture wrinkled, more intense on apex (Fig. 6 D); body whorl about ⅔ total length; rest of whorls slightly convex with a deep suture; aperture complete and pyriform; inner lip thicker than outer lip; peristome margin straight (Fig. 6 C).
Operculum with 2.5 whorls approximately (Fig. 6 E–F) and muscle attachment area oval located near the nucleus.
Radula intermediate length (30% total shell length) bearing about 50 rows of teeth; central tooth formula 5–C–5/(2)1–1(2) (Fig. 6 G–H); lateral teeth formula 3–C–3; inner marginal teeth having 15–18 cusps; outer marginal teeth having 14–16 cusps (Fig. 6 I).
Pigmentation and anatomy
Head dark brown pigmented from snout to the penial base; tentacles also brown pigmented except on ocular lobes; snout as long as wide, with medial lobation. Ctenidium in middle region of pallial cavity with 18–20 narrow gill filaments; osphradium two times longer than wide and opposite middle of ctenidium (Fig. 7 A, Table 3).
Nervous system with black pigmentation and elongate (mean RPG ratio 0.52, Table 3); cerebral ganglia equal in size (Fig. 7 B).
Female pallial oviduct with a capsule gland and albumen gland similar in size (Fig. 7 C, Table 3); pyriform bursa copulatrix with a duct about 50–100% of bursa length; renal oviduct white straight from the insertion point of bursal duct to where it begins to fold; hereafter black pigmented making a simple loop; one small pyriform seminal receptacle with no distinct duct (Fig. 7 D).
Male genitalia with penis simple, gradually tapering, with distal end tapered grayish pigmented (Fig. 7 E– F); prostate gland bean-shaped, about two times longer than wide (Fig. 7 G, Table 3).
Remarks
The small pyriform seminal receptacle and the posterior position of bursa copulatrix relative to albumen gland are the exceptional features of this species related to the species comprising the new pyrgulinid lineage found in this study. Moreover, P. saboori is the most distantly related taxa of this newly recovered lineage (COI p-distances from 6.5 to 8.5%, Table 4).
Ecology and distribution
Only recorded in Khorasan and Markazi provinces (Iran).
