A new species of clypeasterid sea biscuit, Clypeaster brigitteae n. sp., is described from material collected in the Philippines at depths between 100 and 200 m. The new taxon increases the number of Clypeaster species recorded from the Philippines to nine, representing nearly a quarter of the world's diversity of the genus. Other Philippine species include: C. annandalei Koehler, 1922; C. fervens Koehler, 1922; C. humilis (Leske, 1778); C. japonicus Döderlein, 1885; C. latissimus (Lamarck, 1816); C. pateriformis Mortensen, 1948; C. reticulatus (Linnaeus, 1758); and C. virescens Döderlein, 1885. Using type material where available, each of these species is compared and contrasted with C. brigitteae n. sp. in tables consisting of new data derived from general test shape and size, petal structure, food grooves, plate architecture, internal structure, and morphology of spines, pedicellariae, and tube feet.
一种新的盔形目海胆，即布里吉特盔形海胆（Clypeaster brigitteae n. sp.），来自菲律宾水深 100-200 米处的采集样本。新种的发现使菲律宾记录的盔形目海胆物种数量增加到 9 种，占该属全球多样性的近四分之一。其他菲律宾物种包括：安氏盔形海胆（Clypeaster annandalei Koehler, 1922）；高热盔形海胆（Clypeaster fervens Koehler, 1922）；矮小盔形海胆（Clypeaster humilis (Leske, 1778)）；日本盔形海胆（Clypeaster japonicus Döderlein, 1885）；宽板盔形海胆（Clypeaster latissimus (Lamarck, 1816）；异形盔形海胆（Clypeaster pateriformis Mortensen, 1948）；网纹盔形海胆（Clypeaster reticulatus (Linnaeus, 1758）；和绿色盔形海胆（Clypeaster virescens Döderlein, 1885）。利用现有模式标本，通过表格比较了这些物种与布里吉特盔形海胆新种之间的异同，表格内容包括从一般测试形状和大小、瓣结构、食物槽、板结构、内部结构以及刺、小皮棘和管足的形态等方面得出的新数据。
