Etymology. The species-specific epithet comes from the internationally renowned Spanish soccer team Barcelona FC, which is also known as the “Blaugrana” team for the blue and red colouration of its kit and shield which is similar to the characteristic colouration of the abdomen of (male) Phlegra blaugrana sp. nov. Noun in apposition.
Diagnosis. Males of Phlegra blaugrana sp. nov. differ from congeners by having a dorsal shiny scutum on the abdomen surrounded by dense, black, long setae (Figs 2, 9–10), similar to that of P. nitidiventris (Figs 36, 40) but differing by having a shield-shaped central patch with parallel Λ-shaped blue-red-blue-red transverse bands. Females of P. blaugrana sp. nov. are similar to P. nitidiventris in body colouration but differ in the conformation of copulatory organs: broad and long epigynal pocket with three small projections in P. blaugrana sp. nov. (Figs 29–30) vs. relatively small epigynal pocket in P. nitidiventris (Figs 58–59). P. blaugrana sp. nov. is similar to P. dunini Azarkina, 2004 by the conformation of the epigyne but differs in body colouration: with a pattern in P. blaugrana sp. nov., uniformly black in P. dunini (cf. Figs 24–25 and Azarkina 2004: fig. 111 respectively), the shape of copulatory openings are round or oval in P. blaugrana sp. nov. and triangular in P. dunini (cf. Figs 29–30 and Azarkina 2004: fig. 112). Also, the two species differ in the conformation of the endogyne: P. blaugrana sp. nov. has short insemination ducts (long in P. dunini) and large spermathecae (small in P. dunini) (Figs 32–33 and Azarkina 2004: fig. 113 respectively).

Natural history. Ground-dwellers in grasslands on the “Areniscas del Aljibe” Unit, dominated by annual species with scattered shrubs (Calicotome villosa (Poir.) Link, Chamaerops humilis L., Olea europaea europaea L., Crataegus monogyna Jacq.). The area has a high Atlantic influenced climate. Due to its proximity to the sea and several streams there is medium to high relative humidity and high solar irradiance. This area is used extensively as a pasture for the local “Retinta” (cow) breed.
The observations made suggest that the spiders have an annual lifespan. The first adults begin to appear between September–October. The species is diurnal, the adult male, roams the grasslands looking for females. Females, are more sedentary, tending to remain under rocks or in cracks in the ground.
Distribution. Only known from the type locality, south of the Natural Park de Los Alcornocales, Los Barrios-Algeciras, Botafuegos, Spain (Map).
