er, Siracusa, Sicily, leg. F. VALENTINO, IV. 1987, several specimens (author's collection); Anapo river, collector unknown, V. 1889, several specimens, det. HENRY and MAGNIEZ as P. coxalis wolfi (coll. DOLLFUS, Mus. Nat. Hist. Nat. Paris, Is. 2757). Type material: Lectotype, one male (body length 6. 6 mm) from the source of Ciane river (province of Siracusa, Sicily, Italy), leg. E. WOLF, 23. IV. 1925, preserved in 75% alcohol, pleopods partially dissected and mounted on a slide in Faure medium; paralectotypes, 24 specimens from the same locality. The material is deposited in the Crustacea collection of the Hungarian Natural History Museum in Budapest. Diagnosis: Species related to P. peyerimhof fi-group, with incisions formed by linea duplex on exopod of pleopod V approximately equidistant from linea articularis; shape of goulot of male characteristic, with distal part of sternal split wide and opened. Remarks: P. wolfi is a good species, related to P. peyerim hoffi (Racovitza, 1919) from northern Africa more clearly than to P. banyulensis. Both the form of goulot and the shape of linea duplex differ from the ones of the taxa considered above. Asellus coxalis cyanophilus was described by DUDICH (1925a) as co-occurring with P. wolfi: the diagnosis was based on the first two pairs of pleopods of a male only. The material (mounted on a slide) has not been found in the collections of the Hungarian Natural History Museum (FORRÔ, pers. comm.). Moreover the shape of the first pair of pleopods is insufficient to distinguish this species from P. wolfi. So I agree with ARCANGELI (1942) in considering the taxon cyanophilus as a probable synonym of P. wolfi. P. wolfi is not redescribed in the present paper. It was taken into consideration in another work (STOCH et al. in press) dealing with all the epigean species of P. coxalisgroup from Sicily (P. banyulensis italicus, P. montalèntii -Stoch et al. and its subspecies).
