Etymology: The new species is dedicated to Dr. Ersen Aydın Yağmur who made a great contribution to the knowledge of Turkish scorpions and who is a good friend of the authors.

Diagnosis: D. yagmuri sp. nov. resembles D. mariandyna by the long embolus, bent 90 degrees and projected forward. It differs form this species by the rounded rather than flat embolus, which is thinner and twisted upwards in D. yagmuri sp. nov. but sheet-like, only slightly bent in D. mariandyna (Figs 16–19).

The vulva of D. yagmuri sp. nov. is unique among Dasumia species. It is heavily sclerotized and the different parts are firmly fused with each other. (Figs 21–23).

Description: Measurements: [Holotype ♂ / Paratype ♀] TL 5.80–7.20; AL 3.00–4.30; CL 2.80–2.90; CW 2.10–2.20; Clh 0.06–0.08; AEd 0.13–0.13; iAE 0.03–0.06; PLEd 0.12–0.15; PMEd 0.10–0.11; ChF 0.37–0.60; ChG 0.35–0.48; ChL 1.00–1.20.

[Paratype ♂] TL 5.90; AL 3.00; CL 2.90; CW 2.20; Clh 0.06; AEd 0.14; iAE 0.04; PLEd 0.14; PMEd 0.12; ChF 0.37; ChG 0.35; ChL 1.10.

Large harpacteine spiders. There are no differences between males and females in general morphology. Carapace hexagonal, reddish brown. Fovea longitudinal and prominent (Fig. 14). AE, PLE and PME arranged annularly. PME in contact with each other. AMEs and PMEs and PLEs have some distance between them. All eyes silvery, shiny.

Sternum yellowish, labium and gnatocoxae brown. Chelicerae dark brown. Cheliceral groove with four teeth. Promarginal teeth are strongly developed, the same size as each other, about twice as big as the retromarginal teeth. The retromarginals are also the same size, with a distance between them about four times the width of the base (Fig. 15). Abdomen cylindrical, grayish. Female has an epigastral scutum (Fig. 20). Legs yellowish brown. Palpal segments darker than legs. Tip of palpal tarsus in the female whitish. Leg formula: IV, I, II, III. Leg spination and measurements given in Tables 5 and 6.

Palp (Figs 16–19): Palpal tarsus is almost the same length as the tibia. Tegulum oval, longer than wide (Figs 18–19). As it goes towards the tip, it narrows strongly (Fig. 18). Embolus very long, black, almost twice the length of tegulum (Fig. 17). Base of embolus relatively wide but tapering towards the tip (Fig. 16). Conductor shorter than embolus, but well developed, hook-shaped (Fig. 17).

Vulva (Figs 21–23): All parts of the vulva are almost fused together and strongly sclerotized (Figs 21–23). A distinct spermathecal keel is not developed. When the anterior arc is observed dorsally, there is a pair of chitinized apophyses where the spermathecal keel should be located. On both sides of these apophyses, there are sclerotized ear-shaped protrusions. Posterior diverticulum membranous, distinct (Fig. 21).
