Epigyne/vulva. As in diagnosis with EF approximately quadrangulate in shape (Figs 23a, f); MS partially (Fig. 23a) to fully sclerotized (Fig. 23f); MS dorsally with a sclerotized strip (Fig. 23b); vulva equipped with a glandular process (GP) (Fig. 23c). Colouration [in ethanol]. Yellowish brown or reddish brown, dorsal opisthosoma dark brown with small series of yellow chevrons, legs (tibia and femur) clearly banded (Fig. 49e); ventral opisthosoma with V-shaped dark marking in which the mark is not filled with dark colour but is only outlined as “V” with especially the inner lines bold (Fig. 49f). Remarks. The type specimens were collected from Northern Algeria in Constantine Province and around the capital city Algiers (Simon 1874: 253). Unfortunately, the type series could not be located in MNHN neither could the other male specimens identified by Simon. Exceptionally, in this species, females are easily recognized by the shape of the MS of epigyne. Several different tubes containing E. letourneuxi females and juveniles were found in MNHN. Among them a female collected near to the original type locality from Kabylie: Yakouren was selected and designated as neotype to clarify the species identity and reduce taxonomic problems in distinguishing this species from closely similar species in nearby regions of Western Algeria (E. oraniensis), Eastern Algeria (E. barbarus) and Southern Tunisia (E. syrticus). The designated neotype was identified by Simon as E. letourneuxi as clearly indicated by his abbreviation “E.S” on the label, confirming that the specimen is correctly identified to E. letourneuxi. Several sympatric male and female from different localities were used to describe the male. Known geographical distribution and habitat. North-Eastern Algeria in the Atlas Mountains, inhabiting stony areas of mountainous grassland, Cedar and Oak forests.
