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.
