Lepthyphantes longihamatus Bosmans, 1985

MATERIAL EXAMINED. — Morocco. 1♀; Akiam Ins Er Rebi , Agoudal, Ouarzazate; 23.IX.2016; C. Fontgivell leg.; MZB 2016-4071 • 1♂, 1♀, 13 juv.; same locality; 23.IX.2016; F. Fadrique leg.; MZB 2016-4075 • 1♂, 3♀; same locality; 23.IX.2016; F. Fadrique leg.; MZB 2016-4115 • 1♂, 3 juv.; Ifri Bouyzem , Aglefth , Taglefth, Azilal; 20.IX.2016; F. Fadrique leg.; MZB 2016-4079 .

DIAGNOSIS. — In his description, Bosmans (1985) indicates that it is a species very close to Lepthyphantes afer (Simon, 1913) , Lepthyphantes venereus Simon, 1913 and Lepthyphantes emarginatus Fage, 1931 , but it is distinguished from them by its copulatory organs, especially the spine of the patella, the paracymbium with a single posterior tooth, a small lamella characteristica, the clearly trimmed proscape, the very long stretcher and the deep cleft of the median plate.

DISTRIBUTION. — The holotype comes from the cave Akiam Ins Er Rebi, Imilchil ( Bosmans 1985); to this locality is added the one indicated by Tanasevitch (2014), Ifri el Caid, Ait Mohammed. The first belongs to the province of Ouarzazate and the second to Azilal; both are located in the high Atlas of Morocco. Our data confirm its presence in the type locality and add a new one, the Ifri Bouyzem cave, in Azilal.

Lepthyphantes maurusius Brignoli, 1978

MATERIAL EXAMINED. — Morocco. 1♀; Grotte Sidi Megbeur, Sidi Megbeur, Taza; 16.IX.2016; F. Fadrique leg.; MZB 2016-4053.

DIAGNOSIS. — According to Brignoli (1978) the epigyne is characteristic, although typical of the species close to the “ pinicola group”. It will be necessary to confirm this relationship. There is obviously a group of taxa comprising “Spanish-Moroccan forms”, such as L. aelleni , L. taza , L. imazigheni Barrientos n. sp., L. phallifer Fage, 1931 , L. fagei Machado, 1939 and even L. lorifer Simon, 1907 , which could be related. Among them L. maurusius can be easily distinguished by its epigyne and the opening of the bursa copulatrix, which is oriented outwards, instead of backwards or towards the posterior walls.

DISTRIBUTION. — L. maurusius is only known from the type locality ( Brignoli 1978), the cave of Sidi Mejbeur, in the Taza region (high Atlas of Morocco). The data of Tanasevitch (2014) and those given in the present work confirm its presence in the above-mentioned cave.
