Diagnosis Ozestheria lutraria is characterized by a short condyle and a wide occipital notch; straight ventral margin of carapace and strongly supracurvate posterior margin; carapace ornamentation with large, well-developed polygonal reticulations, each polygon without secondary ornamentation (best seen under SEM); male rostrum with convex anterior margin, apex rounded with acute angle, ventral margin strongly concave, pointing apex downwards; female rostrum anterior margin weakly convex, apex pointed with weakly or strongly drawn-out tip, ventral margin strongly concave; 14–24 (male) or 14–20 (female) antenna I lobes reaching to antenna II flagellomeres III–VIII (male) or III–VIII (female); 13– 17 (male) or 14–17 (female) antenna II flagellomeres; 24–27 complete thorax segments; 7–20 (adults usually ~11, juveniles more) usually very small and widely spaced, conical spines (spines in juveniles larger); 8–17 furcal setae. Differential diagnosis Ozestheria lutraria can be easily differentiated. It is the largest growing species (up to nearly 14 mm). The most characteristic features are the carapace shape (oblong, oval), the carapace ornamentation (large polygonal reticulations on all growth bands of the primary growth phase), the largest number of thorax segments (25–28) and telson spination. The morphologically most similar species are O. rufa, O. paralutraria sp. nov., O. sarsii and O. christiani sp. nov. Ozestheria sarsii differs by the shape of the male and female rostrum (i.e., rounded apex), the lower number of thorax segments and antennal lobes, and the polygons of carapace ornamentation of O. christiani are partly intermittent. Ozestheria rufa can be differentiated by the ornamentation (not all wide growth bands with polygonal reticulations) and the shape of the female rostrum (males currently unknown for O. rufa), whose ventral margin is not as strongly concave and whose apex is pointed, but not drawn out into an elongated tip. O. paralutraria can be differentiated by its fewer thoracic segments (24 vs 25–27 complete segments), more telsonic spines (16–18 in O. paralutraria, whereas O. lutraria rarely has more than 15), fewer setae on the carapace (in a single row vs in two rows along each concentric ridge in O. lutraria; best seen under SEM) and by length of the carapace (up to 9 mm vs> 10 mm in O. lutraria). Juveniles of O. lutraria may be confused with other species as their telsonic spines are unusually large and prominent, but the carapace shape is identical to those of the adults.

Type locality Brady (1886) noted “Cooper Creek, at Innamincka, Central Australia ” as the locality. As the type material is lost and the exact locality unknown, we designated a neotype. The new type locality is: Australia, Queensland, Currawinya National Park, claypan halfway on northern fence of Bilby enclosure, 28°52′12.8″ S, 144°21′52.1″ E. Description Males CARAPACE (Fig. 25a–b, d–f). Length 9.6–13.8 mm (NT: 11.0 mm, mean: 11.6 mm), height 5.0– 7.3 mm (NT: 5.6 mm, mean: 6.0 mm). Coloration light brown to dark brown or dark reddish-brown, crowded growth bands lighter, yellowish to whitish (in juveniles carapace lightly colored, sometime
