Oxyoppia (Oxyoppiella) mustaciata N. SP. Measurements: Length of body 205 – 235 µm, Width of body 101 – 119 µm (number of measured specimens 45). Holotype 225 – 112 µm, Cerro Padre Laguna (Río Negro Province) November 2006, soil under N. antarctica. Prodorsum (Figs. 1a, 2, 4, 5) — Rostrum rounded dorsally but sharp laterally, unilaterally externally barbulated ro setae, length exceeding the distance between their alveoli, and the tip of the rostrum; lamellar setae 3-barbulated, slightly shorter than ro setae, about one third shorter than the distance between their alveoli and located near the middle of prodorsum but slightly nearer to in setae; in setae unbarbulated, shorter than the distance between their alveoli; ex setae one-barbulated longer than in setae; ro , le , ex and in decrease in size in this order; costulae with straight section converging to an abrupt inwards curved tapering section connected to the transcostula by a thin curved stretch ending in the alveoli of le setae; curved section of each costula almost connected to an arched lateral ridge directed outwards and then back toward the external border of prodorsum; two pairs of parallel sigilla between the insertion of the in setae, first anterior pair rounded, second posterior pair oval transversally elongated; one pair of toothlike interbothridial tubercles each opposite and posterior to in setae overlap the anterior margin of notogaster; sensillus with fusiform head, 8-aciculated externally and 11-aciculated internally, longest external acicules nearly as long as sensillus head width, internal acicules very short only seen with SEM microscope; bothridium border parallelly striated, striations well defined anteriorly, extended posteriorly and converging to a bundle closing the ring of bothridium and bundle slit arching backwards toward the notogaster, bordered by a postbothridic apophysis opposite to anterolateral border of notogaster next to humeral process (Fig. 1 and indicated by an arrow in Fig. 5).
