description
Description. Holotype, female, 8 mm, ZMUC 7850 of Procyphocaris primata J. L. Barnard, 1961 currently considered a junior synonym of P. indurata (K. H. Barnard, 1925). Body smooth, without setae. Pereonite 1 not produced. Head narrow, much deeper than long, eyes absent; rostrum present, weakly developed; lateral cephalic lobe subacute, anteroventral corner subquadrate. Antenna 1 length extending beyond pereonite 4; peduncular article 1 longer than article 2 – 3 combined; accessory flagellum short, slender, 4 – articulate, not reaching end of primary flagellum first article; primary flagellum article 1 ordinary (very long and densely covered with aesthetascs in male), calceoli absent. Antenna 2 shorter than body (longer than body in male); calceoli absent. Lower lip unknown. Mandibles, mandible incisor smooth, lacinia mobilis multidentate, accessory setal row with 6 (left) setae; molar well-developed triturative; mandibular palp 3 - articulate, article 1 much shorter than 2 – 3; article 2 posterior margin near straight, anterior margin convex, with dense row of submarginal setae distally, article 3 length 0.9 × article 2, lined with dense row of slender setae. Maxilla 1 outer plate with 11 (right) and 11 (left) setal teeth, palp broad (with 6 (right) and 7 (left) robust dentate setae and 1 submarginal plumose seta in male); inner plate tapering distally, with 3 robust plumose setae. Maxilla 2 inner plate triangular, with apical slender and 2 mediofacial setae; outer plate broad, with apical setae only. Maxilliped inner plate rectangular with 3 nodular apical robust setae, medial margin lined with plumose setae; outer plate subovate, apicolateral margin with long plumose setae, medial margin with 7 nodular robust setae; palp long, 4 - articulate, articles 1 – 3 lined with long slender setae; article 1 – 3 length similar; dactylus length 0.8 × article 3, straight, with 3 apical seta, unguis present. Pereon. Gnathopod 1 subchelate; coxa small, ventrally truncate; basis long, length 4.8 × width; ischium broader than long; merus posteriorly produced, acute, posterior surface covered in short fine setae; carpus length 1.2 × propodus; propodus length twice width, palm margin finely serrate, palm acute not defined, with scattered robust setae; dactylus posterior margin smooth, with distal spine, with 2 apical slender setae. Gnathopod 2 minutely subchelate; coxa subquadrate; basis distally bowed, elongate, length 5 × width; ischium length 2 × width, merus 1.8 × width; carpus length twice propodus, length 3.5 × width; propodus length twice width, palm margin serrate, palm defined by corner with 2 robust setae; dactylus posterior margin smooth, with 3 apical slender setae. Pereopod 3 slender, elongate; coxa elongate, longer than broad; basis slender straight; merus longer than carpus and propodus; carpus subequal to propodus length, 2.6 × width; dactylus recurved, length 0.7 × propodus. Pereopod 4 coxa anterior margin rounded, posteroventral lobe produced subacute. Pereopod 5 coxa broadly rounded, subequal to coxa 4; basis posterior margin weakly serrate, produced, reaching beyond ischium, posteroventral corner subacute; merus length 0.9 × carpus, length 1.9 × width; carpus subequal to propodus, length 3.5 × width; propodus length 5 × width; dactylus long, length 0.9 × propodus, straight. Pereopod 6 coxa broadly rounded; basis posterior margin weakly serrate, posterodistal lobe reach end of ischium; merus length 0.9 × carpus, length 2.1 × width; carpus subequal to propodus, length 4.5 × width, propodus long, length 5 × width; dactylus straight, length 0.9 × propodus. Pereopod 7 coxa ventral margin subquadrate; basis subovate, posterior margin convex, with a few weak serrations, posterodistal lobe reaching end of ischium, corner rounded; merus 0.8 × carpus length; propodus subequal to carpus, length 8 × width; dactylus long, straight, tapering, length 0.7 × propodus. Pleon. Pleonites 1 – 3 smooth. Epimeron 1 subquadrate, corner rounded. Epimeron 2 subquadrate. Epimeron 3 posterior distal corner narrowly and acutely produced, posterior margin sinusoidal. Urosomite 1 with anterodorsal notch. Uropod 1 elongate, peduncle with 5 robust setae, length 4 × width; outer ramus 0.7 × inner ramus length. Uropod 2 not reaching end of uropod 3; peduncle with 3 robust setae; outer ramus 1.3 × ramus length, 1.3 × peduncle length, with 7 robust setae; inner ramus with 3 robust setae; rami lateral margins lined with fine setae. Uropod 3 reaching beyond end of telson; peduncle length 2.1 × width, dorsal margin with two long slender setae; rami foliaceous, lined with plumose swimming setae; outer ramus 2 - articulate, length 1.2 × inner ramus, article 2 long, length 3 × width. Telson elongate, deeply cleft to 85 %, lobes tapering distally, acute (notched with subterminal seta in male), lateral margins with 8 setae. Depth range. 1108 – 4050 m.
