Diagnosis.
Telson with double-rounded tips. Antennula with three petaliform aesthetascs. Antennal flagellum with five articles. Molar penicil of mandible with two plumose setae. Male pleopod 1 endopod with four scales at the apex inner margin. Male pleopod 2 endopod stout with distal part tapering.
Description.
Maximum body length: ♂ and ♀ 8 mm. Body outline as in Fig. 5A View Figure 5 . Colourless body, dorsal surface slightly granulated. Pleon narrower than pereon. Telson reduced, about three times wider than long (Fig. 10C View Figure 10 ). Antennula with three articles; third article with three petaliform aesthetascs (Fig. 8F View Figure 8 ). Antenna long; articles of peduncle with small-scale setae and simple setae, flagellum of five articles (Fig. 8C View Figure 8 ). Mandible with molar penicil consisting of two branches (Fig. 9E, F View Figure 9 ). Maxillula (Fig. 5B View Figure 5 ) outer endite with nine to ten simple teeth, two or three serrated setae and one long simple seta; inner endite with one row of small simple setae on inner distal margin. Maxilla (Fig. 5C View Figure 5 ) rounded and covered with many thin simple setae and a row of thick setae. Maxilliped (Fig. 5D View Figure 5 ) endite with long apical penicil; epipodite hairy with a row of elongate setae on distal margin. Dactylar seta bifurcated and plumose. Pereopods increase in size, with pereopod 7 about twice as long as pereopod 1 (Fig. 6A-G View Figure 6 ). Uropods (Fig. 10C View Figure 10 ) with protopod wider than long; exopod as thick as endopod, bearing one row of scales on inner margin; endopod bearing many short setae on apex and one long seta.
Male. Pleopod 1 (Figs 7A View Figure 7 , 10F View Figure 10 ) endopod with pointed tip bent inwards, bearing four scales on inner side; exopod triangular bearing one seta at apex and thin simple setae on inner margin (Fig. 7B View Figure 7 ). Pleopod 2 (Figs 7C View Figure 7 , 10I View Figure 10 ) endopod bent outwards with wide proximal half and thin distal part; exopod with small simple setae on inner margin (Fig. 7D View Figure 7 ).
Etymology.
The new species is named after Mr. Ighous Abdelaziz, the speleologist with whom one of the authors (SM) visited Imi Ougoug Cave the first time and who passed away 5 years ago. He was one of the pioneers of speleology in the Agadir region and one of the founders of the Association Sportive de Spéléologie (ASS).
