Summary: | Paraleptognathia tenuichela n. sp. (Figs 26, 27) Material examined: Six individuals. Holotype ZMH K40631 RV ”Meteor” 48 St. 350, one female. Paratypes ZMH K40632 RV ”Meteor” 48 St. 341, two females (1 dissected), ZMH K40633 RV ”Meteor” 48 St. 346, one female, ZMH K40364 RV ”Meteor” 48 St. 346, one female. Diagnosis: Chela long and slender, rami of pleopods long and slender, no plumose seta. Description: nonovigerous female. Body (Fig. 26a, b): long, about 9.5 times longer than broad. Body length 1.4 to 3.3 mm. Cephalothorax (Fig. 26a, b): about 1.3 times longer than broad. Pereon (Fig. 26a, b): pereonite 1 as long as 6; pereonites 2, 3 and 5 subequal and longer than 1; pereonite 4 longest. Pleon (Fig. 26a, b): pleonites subequal, pleotelson pentameral. Antennule (Fig. 26c): article 1 longest, with one long and four short setae; article 2 with one long simple and one short simple setae; article 3 shortest with two terminal simple setae; article 4 with four terminal setae. Antenna (Fig. 26d): article 1 short, semifused to cephalothorax; article 2 as long as wide, with one short spiniform dorsal seta; article 3 with one simple distal seta; article 4 longest, with two distal simple long, two distal simple short setae; article 5 with one simple long seta distally; article 6 shortest, with two terminal simple setae. Labrum (Fig. 27d): hoodshaped, with row of setules at lateral and apical margins. Mandible (Fig. 27c): well calcified; pars molaris bent ventrally; lacinia mobilis tipped by two tubercles. Maxillula (Fig. 27a): endite with three rows of ventral setules, with eight simple terminal spiniform setae. Maxilla (Fig. 27b): triangular, elongated, smooth. Labium (Fig. 27e): composed of two lobes with three short simple setae at distal outer margin. Maxilliped (Fig. 27f): endites with distal tubercles. Epignath: lost during dissection. Cheliped (Fig. 26g): basis as long as carpus; merus naked; carpus with simple ventral seta; carpal shield weak, poorly developed; propodus long, slender, about three times as ... |
