Sabatieria Rouville 1903 Diagnosis (from Jensen (1979 a)) Cuticle (usually) punctated, lateral differentiation of larger regular or irregular punctations often present; head sensillae in three distinct crowns, with third crown of setae longer than those of second crown; anterior buccal cavity cup-shaped, posterior buccal cavity narrow, not cuticularised; spicules usually short and arcuate; gubernaculum with dorso-caudal or caudal apophyses. Type species. Sabatieria cettensis Rouville 1903 Remarks. Sabatieria is a relatively large genus with over 50 species currently considered valid (Fadeeva &Belogurov 1984; Tchesunov 2000; Botelho et al. 2009). In his review of the genus, Platt (1985) divided Sabatieria into five groups, viz., the praedatrix, pulchra, celtica, ornata, and armata groups. The eight species described herein belong to the praedatrix, pulchra, and celtica groups. Species of the praedatrix group are characterised by simple tubular or pore-like pre-cloacal supplements and straight gubernacular apophyses, whilst species of the pulchra group are characterised by pre-cloacal supplements usually conspicuous and relatively few (5–9) in number, with anterior-most supplements situated more closely together than posterior supplements, characteristic gubernaculum median pieces, short paired cervical setae, and often relatively small size. Species of the celtica group are characterised by curved gubernacular apophyses, conspicuous supplements, fovea amphidialis (usually) with three turns, and relatively large and stout body. The celtica and ornata groups are very similar but species of the ornata group can be differentiated by the presence of a posterior group of more closely situated precloacal supplements. The armata group is characterised by long cephalic (> 1.7 head diameter) and subcephalic setae, and slender bodies (a ratio usually greater than 65). Some controversy remains surrounding the status of S. mortenseni Ditlevsen, 1921 (pulchra group). This species, originally described from Auckland ...
