Campylaspis guerragarciai sp. nov. Fig. 14 Holotype subadult ♀, 4.47 mm, P.88256, Australia, NSW, east of Broken Bay, -33.67° 152.1°, 1108–1115 m, trawl, 19 Dec 1985, FRV Kapala, K85-21-05, in AM. Paratype: 1♀, P.88257 (dissected), collected with holotype. Etymology. The species is dedicated to Dr Manuel Guerra Garcia (University of Seville), specialist on world caprellids, for facilitating my contact with the Australian Museum and their collection. Diagnosis. Carapace about 0.5 body length, lateral sulcus marked by tubercles, covered with spines interspersed with pits; pereonites each with pair of dorsal tubercles, pleonites 1-5 with median tubercles; pleonites 1–4 with pair of dorsal tubercles, pleonite 5 with 3 tubercles pleonite with 2 tubercles; maxilliped 2 propodal seta little longer than dactylar teeth; pereopod 2 without digitiform tip; uropod peduncle 2.25 pleonite 6, 2 longitudinal serrate crests, 1.9 endopod length. Description. Carapace about 0.5 body length; lateral sulcus marked by larger tubercles, a much stronger tubercle on prominence at basis of frontal lobe; ocular lobe without visual elements; marked antennal notch; anterolateral margin with few serrations, covered densely with spines interspersed with pits; pseudorostrum 0.3 carapace length (Fig. 14 A, B, C). — Pereonites each with 1 pair of dorsal tubercles. — Pleonites 1–4 with paired dorsal tubercles, pleonite 5 with 3 median tubercles, pleonite 6 with 2 pairs of dorsal tubercles. — Antenna 1 with basal article of peduncle longer than rest of articles combined, with serrate margins, main flagellum with 3 articles, accessory flagellum, minute, 1-articled (Fig. 14 D). — Maxilliped 2 basis fused with ischium, with a strong plumose medial seta, merus with 1 medial seta, large carpus with 2 setae on medial margin, propodus, 2nd longest article, with short robust outer seta, little longer than dactylus with 3 teeth (Fig. 14 E). — Maxilliped 3 basis little longer than rest of articles combined, 4 plumose setae; merus, 2nd longest article, with strong tooth and 4 plumose setae; carpus about 0.5 merus length, with 2 strong teeth and 1 plumose seta; propodus 1.5 carpus length, with 3 pappose and 1 plumose seta; dactylus 2 shorter than propodus, with 3 simple setae; with exopod (Fig. 14 F). — Pereopod 1 basis 0.8 entire pereopod length, 2 plumose setae; ischium with a plumose seta; merus 3 ischium length, 3 plumose setae, 1.2 carpus length; carpus as long as propodus, with 3 plumose and 2 simple setae; propodus 1.1 dactylus length, with 3 plumose and 2 simple setae; dactylus with 6 simple setae; with exopod (Fig. 14 G). — Pereopod 2 basis 0.55 pereopod length, serrate margins; ischium with 1 plumose seta; merus 4.7 ischium length, with 2 plumose setae; carpus 1.6 merus length, with 2 robust simple and 1 plumose seta; dactylus 2.7 propodus length, with 3 simple and 4 plumose setae; with exopod (Fig. 14 H). — Pereopods 3–5 decreasing basis and increasing carpus; carpus and propodus with 1 annulate seta; dactylus with 1 terminal simple seta (Fig. 14 J–K). — Uropod peduncle 2.25 pleonite 6 length, densely serrated, 2 longitudinal serrate crests, 1.9 endopod length; rami with serrate margins; endopod little longer than exopod; exopod with 1 terminal long simple; endopod with 3 medial setae and a terminal simple seta (Fig. 14 L). Remarks. The new species is closely related to C. australiensis Petrescu, 2006 but differs in: carapace with dense little spines in the new species vs. strong tubercles in C. australiensis, pleonite 5 with 3 dorsal tubercles vs. 2 pairs, pereopod 2 with 1 short dactylus vs. long in C. australiensis; uropod with longer peduncle and 2 longitudinal serrate crests vs. 1. Distribution. Australia: NSW— east of Broken Bay, at 1108–1115 m depth.
