Genus Brignoliolus Ovchinnikov, 1999 stat. rev.

Brignoliolus Ovchinnikov, 1999: 74 (as a subgenus of Coelotes Blackwall, 1841).

Type species. Coelotes turkestanicus Ovchinnikov, 1999 by original designation.

Diagnosis. Predominantly medium-sized (body length mostly 5–10 mm) pale-colored coelotine spiders with an elongate apical segment of the posterior lateral spinnerets. Brignoliolus differs from Coelotes by a lighter overall colouration and a longer and thinner apical segment of the posterior lateral spinnerets that 3–5 times as long as wide, and 1.15–1.6 times longer than preceding segment (vs. respectively 2–2.5 times, and nearly equal in length to the latter in Coelotes; Figs 12–14, 28, 30; Fomichev 2021, fig. 1C cf. Fig. 8; Murphy & Roberts 2015, p. 282, pl. 85), as well as by the distinctive shape of the epigyne with long to very long teeth located anteriorly (vs. laterally) from the anterior margin of the fovea, and with trapezoidal or sandglass fovea (vs. rectangular) (please refre to figures see relatively Figs 6 and 9, 10, 25, 29). Additionally, the species of Coelotes which are related to the generotype, C. atropos (Walckenaer, 1830) possess the well-defined colulus, while in Brignoliolus spp. the colulus is poorly discernible (Fig. 8 cf. Figs 14, 30).

Note. The principal structure of the male palp in Brignoliolus is indistinguishable from that in Coelotes (Figs 2–4 cf. Figs 16–23).

Description. See Ovchinnikov (1999).

Composition. Brignoliolus arganoi (Brignoli, 1978) comb. nov.; B. caudatus (de Blauwe, 1973) comb. nov.; B. charitonovi (Spassky, 1939) comb. nov.; B. coenobita (Brignoli, 1978) comb. nov.; B. juglandicola (Ovchinnikov, 1984) comb. nov.; B. nenilini (Ovchinnikov, 1999) comb. nov.; B. ovchinnikovi sp. nov.; B. turkestanicus (Ovchinnikov, 1999) comb. nov.; B. vignai (Brignoli, 1978) comb. nov.

Distribution. From northwestern Anatolia (Turkey) to the Tarbagatai Mountains (Kazakhstan), and from the Orenburg steppes (Russia) in the north to the Upper Galilee (Israel) in the south (Ovchinnikov 1999; Mikhailov 2022; Nentwig et al. 2024).

Distribution of some species and their type localities are incorrectly shown in Wang & Zhu (2009) and therefore we are providing a map showing all distributional records of all species of the genus.
