Abstract
A new araphid diatom, Diatoma kalakulensis sp. nov., was discovered in Lake Kalakul, located in the Pamir Mountains in north-western China. The morphology and ultrastructure of this new species are described on the basis of observations made under light and electron microscopy. Compared to Diatoma tenuis, Diatoma kalakulensis is characterized by longer valves, higher stria density, wider apical ends and the position of its rimoportula.

Notes
1. Unfortunately, the combination Distrionella germainii f. acosta has been made twice, in the same journal and issue (Flower Citation2005: 62; Morales et al. Citation2005: 133). That means that both have the same publication date. There is no indication in the published versions of which was accepted first. One way to decide between the two would be to accept Flower, as it is the first to appear in the printed copy. It is well known, however, that the sequence of authors is arranged alphabetically. Neither paper presents further images of Distrionella germainii f. acosta. While it may be of no great significance, we have accepted Flower as the author of the combination. We accept, too, that this might be further debated.
