Telodiacria danae

Abstract

Telodiacria danae (Van Leyen & Van der Spoel, 1982) (Figs 5 L-N) Description. – Shell slightly elongate in outline, relatively wide (L 1.2-1.8 mm, W 1.0 - 1.4 mm), dorsal shell part with five vaguely indicated longitudinal ribs, weaker towards the caudal spine mark, with marked growth lines in between and about three imbricate transversal striae adjoining the aperture. The lateral spines point slightly in a caudal direction. Ventral part of the shell globose and smooth with about four transverse imbricate stria. In fresh specimens the thickened apertural margins are brown. Remarks. – Easily identifiable as smallest of the Telodiacria species with a virtually smooth shell. Distribution. – Few specimens have been found on the Sarawak inner to mid shelf coral banks (only Tukau and Batu Mat which are further from the shore) and in middle (DD95) to outer (DD92-93) shelf sand in Sabah, but the species is more abundant in outer shelf sediments (DD29) and in continental slope planktonic ooze (DD15) in Sarawak and on the Royal Charlotte atoll, Spratly Islands. It is always accompanied by the more numerous T. costata.
