Dolichurus haemorrhous A. Costa, 1886 (Figs 8–10) Dolichurus haemorrhous A. Costa, 1886: 68, ♀. Holotype or syntypes: ♀, Italy, Puglia, Ruvo [Museo zoologico, Napoli, Italy]; Shorenko 2007: 554 (Crimea); Mokrousov & Popov 2016: 550 (Krasnodar Terr.). Material examined. Russia. Crimea, 1 ♂, Tankovoe, 18.VII.1979, Kotenko [ZISP]; Dagestan, 1 ♀, Barkhan Sarykum [43.01ºN 47.23ºE], 26. VI.2017, N. Gasanova [MMC]; 2 ♂, Samur Reserve [41.8667°N 48.5565ºE], 6– 8. VI.2017, MM; 2 ♀, 2 ♂, ibid, 4–5.VII.2018, MM, KF [MMC]. Turkey. Antalia, 4 ♂, Beldibi [36.69°N 30.569°E], 7, 9.IX.2019, MM [MMC]; 2 ♂, near Göynük [36.682050ºN 30.566229ºE], 10.XI.2019, MM [MMC]. Distribution. Russia (Crimea, Krasnodar Terr., * Dagestan); Central and South Europe, North Africa, Abkhazia, Turkey. Remark. The species is very similar to D. corniculus Spinola and all used features do not allow to reliably distinguish these species. In females, the metasomal coloration is not absolute, but only more or less reliable feature. Whitish spots on head and pronotum may be developed in both species. Legs’ color and sculpture (on mesopleurae and metasomal terga) of males are very variable and overlap widely. Study of male genitalia ( D. corniculus from Karelia, Nizhny Novgorod Prov., Krasnodar Terr., and Dagestan, and D. haemorrous from Crimea, Krasnodar Terr., Dagestan, and Turkey) allowed to find differences between these species (Figs 5–10). The most stable is the width of the penial valvе. In D. corniculus apical part is wider, and more broadly rounded apically than in D. haemorrhous (lateral view, Figs 6 vs 9). Digitus longer and the base of the volsella is shorter in D. corniculus (Figs 7 vs 10); volsella apically is variable but usually longer in D. corniculus . Paramera in D. corniculus basally strongly constricted (Fig. 5). It is possible that both species are only color forms of the variable D. corniculus (Spinola, 1807).
