Types: Type series of Drassus macellinus from France, Nice, containing 7♂ and 8 juveniles; NHRS 179a; examined. Holotype ♀ 1 subadult ♀ paratype of Drassus nyctalicus from France, Nice; NHRS 179b; examined. Holotype ♀ of Drassus vicarius from Corsica; not examined, inavailable. Holotype ♂ of Drassus hebes from France, Menton, J.T. Moggridge leg., II.1874; HECO; not examined. Holotype ♂, paratype ♀ of H. vignai View in CoL from Italy, Lazio, Tuscolo; deposited at MZUR; not examined.

Diagnosis. Males are closely related to H. securifer sp. n. but are easily distinguished by the much shorter and wider embolic apophysis ( Figs 237 View FIGURES 232–240 versus 128). Females are distinguished by the elongated epigyne with rounded, narrow hood, a relatively small areola and a longitudinal internal sclerite accompanying laterally the pro-fovea ( Figs 238‒240 View FIGURES 232–240 , LS). However, this lateral sclerite was found to be absent in a few specimens.

Remarks. According to the World Spider Catalog (2017), Haplodrassus macellinus is a West Mediterranean species. Various authors cited it frequently in France and Italy, and in the Maghreb ( Denis 1937; Di Franco 1994; Pavesi 1884; Simon 1885, 1908). There are also two citations from Greece and Turkey (Caporiacco 1948; Karol 1966). One can wonder however how these specimens where identified, when the only available figure of H. macellinus is a simple sketch of a part of the male palp by Simon (1914), and the epigyne has never been figured at all. Simon (1914) already stated that the species is very variable, when he declared Drassus hebes O.P.- Cambridge, 1874, D. nyctalicus Thorell, 1871 , D. occidentalis Thorell, 1871 , D. typhon Simon, 1878 and D. vicarius Simon, 1878 all simple variations of D. macellinus (“des formes très variables”). The descriptions of all these species were carefully analysed by us and if possible, the type material was examined.

The type material of H. macellinus from Nice, France, was found in the NHRS, which undoubtedly fixes the identity of the species. Thorell (1871) described the male and a juvenile female (“onne omnino adulta?”). The type series indeed contains adult males and only subadult females. In the same paper, Thorell described Drassus nyctalicus and D. occidentalis , of both only females and also from Nice. Examination of the type material of D. nyctalicus confirms it is the female of H. macellinus , as proposed by Simon (1878). Later, Simon (1914) considers D. occidentalis a simple variation of H. macellinus (“forme de D. macellinus ”). Type material of this species was not available, and Simon’s view is followed here.

Drassus hebes O.P.- Cambridge, 1874, described from France, Menton, at 20 km from the type locality of H. macellinus View in CoL , is another problematic species. Simon (1878) considered the species a synonym of H. macellinus View in CoL and a subspecies in 1914. Type material was not available, but Cambridge’s figure 15 of the male palpal tibia of D. hebes agrees well the elongated palpal tibia of H. macellinus View in CoL . Also the material of D. macellinus hebes View in CoL examined in the MNHN is identical to H. macellinus View in CoL . The evident conclusion is D. hebes is a junior synonym of H. macellinus View in CoL . Drassus vicarius Simon, 1878 was described on a female from Corse. Simon (1914) considered it a synonym of D. macellinus hebes View in CoL . Since the type material is not available, Simon’s vision is followed here and Drassus vicarius enters into the synonymy of H. macellinus View in CoL .

Drassus typhon Simon, 1878 was described on the syntypes male and female from the Pyrénées-Orientales. Simon (1914) considered it another synonym of H. macellinus View in CoL . An adult female identified by Simon shows it is a distinct species and it is taken out of the synonymy of H. macellinus View in CoL . It is described above.

The synonymy of H. invalidus (O.P.- Cambridge, 1872) from Israel, Turkey and Azerbaijan with H. vignai Di Franco, 1996 from Italy as proposed by Levy (2004) is here rejected. Material of recently collected H. invalidus in Cyprus compared with material collected in Italy near the type locality of H. vignai shows clearly they are two different species. In H. invalidus , the tibial apophysis has a claw-like tip, and the embolus has an inner spur-like process, as excellently shown by Kovblyuk et al. (2012). These are both absent in H. vignai , as shown in Di Franco’s figures 1‒4 of H. vignai . Although the type material of H. vignai was not examined, H. vignai is considered here a junior synonym of H. macellinus .

Description. Measurements: Male (n=7): Total length 4.4‒8.2; carapace 2.38‒3.74 long, 1.68‒2.69 wide. Female (n=1): Total length 11.0; carapace 3.71 long, 2.98 wide.

Colour: Carapace brown to dark reddish brown, cephalic part infuscate; chelicerae dark brown; sternum yellowish to reddish brown, darkened to the margins; legs yellowish brown to reddish brown; abdomen grey to brown with paler venter.

Male palp ( Figs 235‒237 View FIGURES 232–240 ): Tibial apophysis slender, as long as its diameter, constricted in the middle, with broadly truncate tip; embolar apophysis much shorter than embolus, with only slightly bent margins, getting somewhat broader distally, terminally bluntly pointed.

Epigyne ( Figs 238‒240 View FIGURES 232–240 ): Elongated, 1.4 x longer than wide, with rounded hood, which is much narrower than the total epigyne; pro-fovea somewhat longer than fovea; lateral pockets sac-like.

MAP 8. Distribution of Haplodrassus macellinus (Thorell) .

Distribution. According to the literature and the World spider Catalog (2017), the species occurs in the West European and African Mediterranean region. All material from the Maghreb identified as H. macellinus that could be examined appeared to be misidentified, and the species is not present in our abundant material. Only the records from France including Corsica, and Italy including Sicilia are confirmed here (map 8). Citations from Portugal and Spain are possibly correct but should be confirmed. Citations from Rhodes by Caporiacco (1948) and from Turkey by Karol (1966) are considered misidentifications.
