Paratouphapleura aaroni gen. et sp. nov. urn:lsid:zoobank.org:act: 6F7C1F0C-7A6F-473A-B5B4-78859FE44D59 Figs 8–14; Table 2 Etymology The epitheton aaroni is given in fond dedication to my brother, Mr Aaron Martin George (Münster/ Selters, Germany). Type material 3 ♀♀, 3 ♂♂, collected during research cruise ANT-XIX/4 (ANDEEP II) of RV POLARSTERN in 2002. Holotype ANTARCTICA • ♀; Weddell Sea, E of Antarctic Peninsula; station #133; 65°20.30' S / 54°14.67' W; depth 1109.6 m (locus typicus); multiple corer; SMF 37270/1, on 1 slide. Paratypes ANTARCTICA • 2♀♀, 3 ♂♂; same collection data as for holotype; SMF 37271/1 (♂ paratype 1/allotype, on 1 slide), SMF 37272/1 (♀ paratype 2, on 1 slide), SMF 37273/1–9 (♀ paratype 3, on 9 slides), SMF 37274/1–8 (♂ paratype 4, on 8 slides), SMF 37275/1 (♂ paratype 5, on 1 slide). Description Female HABITUS (Fig. 8A). Elongate, cylindrical; body length including FR: 493 µm (holotype), 562 µm (paratype 2), 515 µm (paratype 3). Podoplean boundary between pro- and urosoma inconspicuous. Cphth about ⅓ of total body length, with some sensilla and long tube pores laterally and dorsally, and with anterior cephalothoracic setulose tufts (ACST). Cephalic front produced into a moderate peak, from which the A1 arises. Without frontolateral horns (FLH), but cephalothoracic anterior lateroventral processes (CLVPa) weakly developed, ending in long tube pore; sensilla not discernible. Cphth additionally with 3 pairs of tube pores, two of which located dorsally, the third laterally. Cephalothoracic posterior lateroventral processes (CLVPp) (Fig. 9B) long and jet-wing-like, with 1 sensillum halfway on anterior margin and 1 sensillum on its tip. Rostrum (Fig. 9A) small, broader than long, fused to cephalothorax; with pair of sensilla, 1 tube pore, paired membranous projections, and rostral setulose tuft (RST). P2–P4-bearing thoracic somites (Fig. 8A) dorsally with 1 tube pore and paired unarmoured small cuticular processes (DP1–DP3), each carrying a sensillum at its tip; laterally with ...
