摘要

摘要报道了2个弯曲种和1个直种的新记录;这两个新物种都没有在属型中看到的棘条。在大小和质体数量(2对)上与关岛和灯叶相似，但具有更细的条纹(10 μ m内46-50条)。C. leandrei有多个质体，很长，像C. koenigii一样，但更纤细，有矩形而不是圆形的乳晕。本种Valvocopulae在Climaconeis属中首次被描述，在其他交配科中无明显区别。本文首次报道了一种在热带水域的直系种，暂定为角鳞棘鱼(C. scalaris)。提供了18种已知物种的最新密钥。

Climaconeis desportesiae and C. leandrei (Bacillariophyta, Berkeleyaceae), Two New Curved Species from Guam, Western Pacific

Abstract Two new curved species and a new record of a straight species are reported; neither new species has the craticular bars seen in the generitype. C. desportesiae resembles C. guamensis and C. riddleae in size and number of plastids (2 pairs) but has much finer striae (46–50 in 10 µm). C. leandrei has multiple plastids and is very long, like C. koenigii but more slender and with rectangular rather than circular areolae. Valvocopulae of this species are described for the first time in Climaconeis spp., which otherwise show no distinction among copulae. A straight species, provisionally identified as C. scalaris, is reported for the first time from tropical waters. An updated key to the 18 known species is provided.
