Other material . France8 sub-adult specimens; same data as holotype; Eco & Sols . ETYMOLOGY . — The species name is derived from the massif of Luberon where the type specimens were found. ECOLOGY . — F. luberonensis Gérard, Decaëns & Marchán , n. gen., n. sp. was found in a Mediterranean shrubland (garrigue) soil at low elevation ( 434 m a.s.l.). DISTRIBUTION. — F. luberonensis Gérard, Decaëns & Marchán , n. gen., n. sp. is only known from the type locality, near the city of Saint-Saturnin-les-Apt, between the massif of Luberon and the Vaucluse mountains in the Vaucluse department ( Provence-Alpes-Côte d’Azur , France ) ( Fig. 5 ). It is located in the Luberon Regional Natural Park (Parc naturel régional du Luberon). DESCRIPTION External morphology ( Fig. 3A, B ) Body shape cylindrical. Body pigmentation absent, mid-segmental dark dots in the cephalic region. Average body length after ethanol fixation: 80 mm (range: 70 to 100 mm ; n = 3 adult specimens; holotype : 100 mm ). Average body mass: 1.163 g (range: 0.855 to 1.398 g ; n = 3; holotype : 1.398 g ). Average diameter: 4.6 mm in the preclitellar region (range: 4.2 to 5.4 mm ; n = 5; holotype : 5.4 mm ), 5.8 mm in the clitellum (range: 5.2 to 6.8 mm ; n = 5; holotype : 6.8 mm ), 4.6 mm in the postclitellar region (range: 4.2 to 5.2 mm ; n = 5; holotype : 4.7 mm ). Average number of segments: 283 (range: 187 to353; n = 3; holotype : 309). Prostomium of closed epilobic type . Setae closely paired. Setal arrangement: aa:ab:bc:cd:dd = 14:2:8:1:32. Clitellum in XXXII-XLII (XLIII). Genital markings in XI-XII, randomly unpaired in XXVI-XXVIII, intraclitellar in XXXIV, in ab. Tubercula pubertatis: protruding band in XXXV-XL. Male pores: one pair in XV. Ovipores: one pair in 1/2 XIV, at 1 × ab dorsally from b. Spermathecal pores not visible. Nephridial pores not visible.

Photos: T. Decaëns. Scale bars: 5 mm. Internal anatomy ( Figs 3C ; 4 ) Septa : thickened from 5/6 to 9/10, otherwise membranous. Crop in XV-XVI. Muscular gizzard in XVII-XVIII followed by a membranous pouch in XIX, with an average size (width × length) of 3.55 × 2.10 mm . Calciferous glands: in X-XIV, forming a pair of spherical lobes in X. OEsophagus-intestine transition in XV.Typhlosole starts in XX, forming four folded lamellae. Hearts: in VI-XI. Excretory apparatus: one pair of holonephridia per segment, nephridial vesicles sigmoid with a sub-terminal constriction followed by a loop ( Fig. 4 ). Seminal vesicles: two pairs in XI-XII, large and lobulated. Spermathecae: two pairs in X-XI, intracoelomic, sessile and double ( Fig. 3C ).

REMARKS This species can be distinguished from its closest relative F. bartolii bartolii ( Bouché, 1970 ) n. comb. by the position of its clitellum and tubercula pubertatis ( Table 4 ) and by their remarkably high genetic distance (12.14% uncorrected pairwise COI distance).
