Oskoron Shear, new genus Type species: Taracus spinosus Banks 1894. Diagnosis. Distinct from Taracus, to which it is closely related, in the enlarged, glandular patellae of the male palps (Figs. 139, 140, 143, 155, 162), the prominent, curved, black setae of the abdomen set on conical tubercles, and the similar enlarged setae of the ocularium (Fig. 134); the small endites of the second coxae are set in unsclerotized recesses in the coxae, rather than entirely free from them, as in Taracus. The first leg coxae bear prominent seta-tipped tubercles, sometimes weak or absent in Taracus. In males, the glans penis is abruptly narrowed into the aculeus (Fig. 130), not evenly tapered as in Taracus. For distinctions from other sabaconid genera, see the Diagnosis section under Taracus. Description. Body length from 2–5 mm. Carapace black or dark chestnut brown in adults, broadest behind, with midline sulcus extending from between chelicerae to ocularium; in lightly pigmented specimens, two prominent slit sense-organs just anterior and lateral to ocularium; carapace often poorly sclerotized posteriorlaterally, smooth to finely shagreened texture. Ozopores prominent, not concealed, dorsolateral, over first leg coxae. Ocularium relatively high, at least as wide as long; sharply inclined anteriorly, gradually sloping posteriorly; prominent tubercles with large, black, curved setae above each eye. Eyes large, protuberant. Metapeltidium sclerotized or not, may appear free, or partially or wholly coalesced with carapace, with transverse row of prominent setae; sensory cone single, median, flanked by smaller acute tubercles with apical setae, set into unsclerotized embayment in posterior margin of carapace. Abdomen soft, white, densely but irregularly set with distinct sclerotized tubercles, each bearing single, black, curved seta, tubercles sometimes larger near midline, sometimes coalesced in midline to form small segmental sclerites (partial scutum laminatum), or with true scutum laminatum; males often with scutum parvum, but ...
