Abstract

A new species of Leucosoleniidae, Leucosolenia qingdaoensissp. nov., is described. This new species was collected in a scallop-breeding pond from the Yellow Sea and preserved in 75% ethanol. This sponge consists of a dense reticulation of ascon tubes, with the surface minutely hispid and the consistency soft and fragile.<br> Spiculation of the new species consists of diactines, which are smooth, straight or sometimes slightly curved, triactines of two types, and tetractines with short and curved apical actines; spiculation also slightly overlaps and is somewhat irregularly assembled. Together these form a thin layer of skeleton, with a small number of cells, which results in a transparent, white sponge. As a typical asconoid feature, all internal cavities of the sponge are lined with choanocytes, and there is no fully developed inhalant system. Comparisons with other Leucosolenia reported from the Pacific Ocean are also made.
