Chaetoceros dadayi Pavillard (1913: 131) View in CoL ( Fig. 4 View FIGURES 2–12 )

References:— Hustedt (1930), Cupp (1943), Hernández-Becerril (1992).

Morphometry: —a.a.: 7–17 μm; p.a.: 7–26 μm.

LM: —Heteropolar and short chains, composed of only three cells ( Fig. 4 View FIGURES 2–12 ), are typically attached to the lorica of the ciliate tintinnid Eutintinnus sp. In girdle view cells are rectangular with round valve corners, valve mantle is not visibly constricted. Numerous chloroplasts are present in the cell body and the setae ( Fig. 4 View FIGURES 2–12 ). The apertures are either very narrow or absent, and the sibling valve faces are closely pressed on each other. After the crossing point, the setae strongly curve becoming almost parallel with the chain axis, but they differ in their orientation and morphology. Some setae are shorter and oriented towards the posterior end of the chain to embrace the lorica of the tintinnid, whereas two intercalary setae are directed to the anterior chain end ( Fig. 4 View FIGURES 2–12 ).

Distinctive features:—Two setae of the neighbouring cells on the same side directed towards the anterior side of the chain while all other setae are oriented towards posterior side. Lorica of the symbiotic ciliate Eutintinnus sp. attached to the chain.
