Lamiantennula longifurca Markhaseva & Schulz, 2006 (F) | |
| | | | | | | Ref.: | | | Markhaseva & Schulz, 2006 b (p.204, figs.F, Rem.: p.209); Bradford-Grieve, 2010 (p.2171: u>Rem.) |  issued from E.L. Markhaseva & K. Schulz in Arthropodia Selecta, 2006, 15 (3). [p.205, Fig.1]. Female (from 64°02'S, 39°07'W): A-B, habitus (dorsal and lateral, respectively); C-D, anterior part of cephalosome (lateral and ventral, respectively); E, urosome (dorsal; upper arrow indicates proximal vestigial lateral seta, lower arrow indicates scar from broken distal lateral seta); F-G, idem (left and right lateral, respectively); H, genital double-somite (ventral); I, distal part of right caudal ramus (dorsal; arrow indicates distal lateral seta broken, only scar is observed). Scale bars: 0.5 mm (A-B); 0.1 mm (C-I). Nota : Prosome 1.4 times as long as urosome. Rostrum with 2 long and slender filaments. Cephalosome and pediger 1 separate, 4th and 5th fused. Genital double-somite longer than urosomites 2-4, slightly asymmetrical in dorsal view ; genital structures asymmetrical. Anal somite shortest. Caudal rami symmetrical, 1.2 times as long as urosomites 1-4, with 7 setae (1 small proximal lateral seta, 1 distal lateral seta broken (only scar), 4 large terminal setae and 1 small dorsal seta).

 issued from E.L. Markhaseva & K. Schulz in Arthropodia Selecta, 2006, 15 (3). [p.206, Fig.2]. Female: A, left A1, segments 1-11 (ancestral segments I-III, IV-XIII); B, idem, segments 12-17 (ancestral segments XIV-XIX, segment 18 broken. Scale bar: 0.1 mm. Nota: Segment 1 is a complex of ancestral segments I-III.

 issued from E.L. Markhaseva & K. Schulz in Arthropodia Selecta, 2006, 15 (3). [p.207, Fig.3]. Female: A, A2; B, Mx1 (setation of coxal endite, endopod and exopod omitted, arrow indicates epipodite); C, Mx1 (coxal endite, endopod and exopod); D, Mx2 (armature of basis and endopod omitted); E, Mx2 (basis and terminal part of limb with endite and endopod); F, Mxp (inner lamella of endopodal segments 5 and 6 stippled). Scale bars: 0.1 mm. Nota : A2 : coxa without seta ; basis with 2 unequal setae ; exopod 9-segmentd as long as endopod, with 0, 0, 1, 1, 1, 1, 1, 0 and 3 setae ; endopod segment 1 with 2 subdistal setae, segment 2 with 4 + 6 setae. Mx1 : praecoxal arthrite larger than rest of appendage, with 16 elements (3 slender setae plus 7 robust spinulose spines, 4 posterior and 2 anterior setae ; coxal endite with 3 setae ; proximal basal and distal endites reduced, unarmed ; endopod long with 3 distal setae ; exopod with 2 distal setae ; coxal epipodite without setae. Mx2 : proximal praecoxal endite with 5 setae, distal with 1 seta ; proximal coxal endite with 2 setae, distal with 3 setae ; basis with angula router crest ; proximal basal endite with 4 setae (1 very small) ; terminal part of Mx2 (endopod ?) proximally with 4 setal elements on 1st large endite (2 thick and spinulose spines, 2 thin short setae) and distally with 6 long and 1 short strong, spinulose setae.

Female: A, right Md (mandibular palp); B, left Md (exopod); C, left Md (gnathobase); D, left Md (teeth of cutting edge); E, left Md (terminal setae of endopod segment 2); F, P1 (anterior); G, P1 (basis with poorly scleritized posterior spine and exopod segment 1; lateral view); H, P2 (posterior); I, P3 (posterior); J, P4 (posterior); K, P5. Scale bars: 0.1 mm. Nota : P1 : coxa with medial seta ; basis with distomedial seta strongly curved and with poorly sclerotized spine on posterior face . P5 symmetrical, uniramous ; coxa and basis fused, with 1 distolateral seta ; exopod 1-segmented, incompletely separate from basis, with 2 terminal setae (1 long, 1 short and spine-like).
