In the bulb, the lamella characteristica is fused at the base with the terminal apophysis, making a bifurcated structure: the terminal apophysis is short, narrow and sinuous; the lamella characteristica is narrow and extends forward on the outer side of the bulb, apically denticulated at on the margins. The female is characterized by the peculiar conformation of the epigyne: the walls of the bursa copulatrix protrude, moving its opening away from the epigastric wall. The lateral walls differentiate an elongated process (“wings”) on each side, flanking a reduced proscape, as well as the rest of the scape, which is not very apparent.  Lepthyphantes tazacould be related to a set of species from the Maghreb,  L. aelleni,  L. maurusius,  L. imazigheniBarrientos n. sp.and  L. sasiBarrientos n. sp.(although in the latter there are features in the female genitalia that bring it closer to the “  afergroup”).  DISTRIBUTION. — This species was only known from the typelocality ( Tanasevitch 2014). We add other caves here in the same region of Chara, south of Taza, in the Moroccan Atlas.  DESCRIPTION  Male  Body.Total body length: 2.63. Carapace: 1.02 long and 0.96 wide, pale brown yellowish, uniform. Scattered hairs in the cephalic area, up to the eyes. Eyes relatively small, but visible and surrounded by a black areola. Chaelicerae with 0.36 long stem, with three teeth (one bigger) and a minor denticle on the promargin; on the retromargin a small slightly denticulated edge. Legs pale brown yellowish; lighter in distal articles (metatarsus and tarsus); relatively long and thin; measurements: leg I (2.11 + 0.38 + 2.24 + 1.92 + 1.06), leg II (1.95 + 0.35 + 1.89 + 1.79 + 1.02), leg III (1.79 + 0.32 + 1.47 + 1.44 + 0.90), and leg IV (1.92 + 0.35 + 1.86 + 1.86 + 0.99). Opisthosoma, length 1.60, width, 0.90, pale yellow, whitish and without dorsal pigmentary pattern.  Palp and copulatory bulb( Fig. 10A-C). Paracymbium narrow; proximal part wide, with rounded edges and small hairs; middle part with an acute denticle at the posterior end (which closes the posterior pocket) and a laminated three-pronged denticle at the anterior end (which in turn delimit the posterior pocket); apical part finger-shaped, bent distally. With the bulb at rest: radix well visible ventrally on prolateral side. Lamella characteristica fusing at the base with the terminal apophysis, protruding from the back, so that it appears as a bifurcated structure. Anterior branch short, narrow and sinuous; posterior branch laminar, narrow, longer and extending forward on the outer side of the bulb; distal part darker, with denticulate margins. Embolus emerging from the middle part of the radix; quite complex: main part simple, laminar, widened in its middle part and finished in a black bifurcated tip; accompanied, from the base, by a sheet becoming translucent and protecting distally the main part. Fickert’s gland visible in the radix. Suprategular apophysis sclerotised, pointed and curved, protruding below the embolus and facing forward. 2558291722 2009-09-03 MZB Cv. Trou de la Piste & A.
