Diagnosis: Carpal shield well developed. Pereopod 1, 2, 3 with spinules on merus, carpus and propodus. Description: nonovigerous female. Body (Fig. 22a, b): long, about 7.3 times longer than broad.

Antenna (Fig. 22d): article 1 short, semifused to cephalothorax; article 2 as long as wide, with one short spiniform seta dorsally; article 3 with one simple distal seta; article 4 longest, with two distal simple long, two distal short and one short simple setae at midlength; article 5 with one simple long distal seta; article 6 shortest, with five terminal simple setae. Labrum (Fig. 23d): hoodshaped, with row of setules on lateral margins. Mandible (Fig. 23c): well calcified; pars molaris bent ventrally; lacinia mobilis spiniform and blunt. Maxillula (Fig. 23a): endite with three rows of ventral setules, four rows of dorsal setules, with one simple and eight pinnate terminal spiniform setae.

Maxilliped (Fig. 23g): endites not fused, with a distal tubercle, basis tongshaped. Epignath (Fig. 23b): with no special features. Cheliped (Fig. 22g): basis as long as carpus; merus with ventral simple seta; carpus with a ventral and a dorsal simple setae; carpal shield well developed, about one third of carpus; propodus smooth, with two teeth at cutting edge; dactylus smooth.

Pereopod 5 (Fig. 22l): as pereopod 4, except basis with three simple setae; merus with two spiniform setae, propodus with three terminal spiniform setae, dactylus with larger spinules as in pereopod 4 and 6. Pereopod 6 (Fig. 22m): as pereopod 4, except propodus with four terminal spiniform setae. Pleopods (Fig. 22f): exopod with eight simple long setae, endopod with seven simple long setae. Uropods (Fig. 22e): exopod half the length of article 1 of endopod. Exopod article 1 with one simple seta; article 2 with one terminal simple seta. Article 1 of endopod with two simple setae; article 2 with six terminal setae. Juvenile males body length 3.32 mm. Mancas up to 1.5 mm. Type locality: South Atlantic Ocean, Angola Basin, RV ”Meteor” 48 St. 340 18° 77.3´S 04° 41.2´E– 18° 19.4´S 04° 41.9´E, 5395 m. Etymology: the name refers to the Benguela Current that flows on top of the Angola Basin. Distribution: South Atlantic Ocean, Angola Basin. Remarks: this species resembles P. bacescui but the presence of spinules on the merus and carpus of P1 to P3 on P. benguela distinguish them. A detailed analysis of the type of P. bacescui is needed to define these two species more properly. : Published as part of Guerrero-Kommritz, Jürgen, 2004, A revision of the genus Paraleptognathia Kudinova-Pasternak, 1981 (Crustacea: Tanaidacea) and description of four new species, pp. 1-63 in Zootaxa 481 (1) on pages 49-52, DOI: 10.11646/zootaxa.481.1.1, http://zenodo.org/record/5030070 |
