Oxus ( Flabellifrontipoda ) neotropical (Lundblad, 1953) (Figs 1- 15) Material examined. 2 deutonymphs, 5 females: South America, Chile, Region de Magallanes y de la Antartica Chilena, Provincia de Magallanes, stream south of Punta Arenas (53°34'29” S 70°56'23” W), depth 0.4 m, substrates: stones and mosses, 8 November 2014; 5 deutonymphs, 3 males, 1 female: Chile, Region de Magallanes y de la Antartica Chilena, Provincia de Magallanes, NW of Villa Tehuelche, stream(52°05'537"S 71°48'061"W), depth 0.4 m, substrates: stones and mosses, 8 November 2014, leg. V. Stolbov. Deutonymph. Idiosoma elongated, laterally compressed (Fig.1). Lateral eyes not in capsules, lying below integument. Trichobothria Fp, Oi and setae Pi not associated with glandularia, other idiosomal setae associated with glandularia. Seta Fch longer and thicker than other idiosomal setae. Coxal plates large, fused on each side into two groups and occupying about one half of idiosoma surface. Two pairs of idiosomal setae and glandularia ( Hv and Pe ) incorporated into the coxal region on each side, other idiosomal setae and all slit organs located on soft integument. Glandularium Pe lying near tip of first coxal plate, accompanied by a hyaline projection and modified seta. Dorsum with two small oval anterior platelets bearing trichobothria Oi and three pairs traces of muscle attachment scars (Fig. 2), the latter usually hardly visible. Soft integument striated, surface of coxal plates porous. Genital field consisting of two very narrow lateral plates, two pairs of acetabula, three pairs of setae (one pair located anteriorly and two pairs posteriorly) and the small pregenital sclerite (Fig. 3). All acetabula subequal or posterior pair a little large than anterior pair. Excretory pore unsclerotized. Figure 4 shows the lateral view of the capitulum and chelicera. Capitulum with a widely rounded protrusion a little distally to middle of ventral margin. Basal segment of chelicera large with convex dorsal margin, chela thin and pointed, sigmoid piece long ...
