Synonymy: Ledaspina Marwick, 1931 (Maxwell 1988a, p.40)
Classification: Sareptidae: Yoldiellinae
Description: Length 2.5-7 mm, ovate, rather thin-shelled, posterior end narrowly rounded or rostrate; shell smooth or with distant, fine commarginal ridges. Hinge relatively narrow, broadly angled, anterior and posterior series separated by well defined resilifer. Pallial sinus shallow, rounded.
Comparison: Species of Jupiteria (to which some New Zealand species of Yoldiella have been assigned) are relatively robust, and are of trigonal shape with the posterior rostrum situated in a lower (more ventral) position than in Yoldiella.
Distribution: Mangaorapan-Recent, New Zealand; widely distributed, probably cosmopolitan. Characteristic of moderately deepwater assemblages (outer shelf to upper bathyal).
