Abstract

The poorly known Philippine freshwater crab, Sundathelphusa picta (von Martens, 1868) from Luzon Island is re-described and re-illustrated, using type material as well as other specimens sampled from near its type locality. Two similar congeners from Luzon, S. uva sp. nov. and S. angelito sp. nov., from the provinces of Bataan and Rizal, respectively, are described as new. These three species are united by their relatively small size, rounded and dome-shaped carapaces, proportionately short ambulatory legs, and stout male first gonopods. They are distinguished from each other by a suite of morphological characters, particularly of the carapace, male pleon and gonopods.

来自过去的回声——图片太阳蟹的身份（von Martens，1868）和对菲律宾吕宋岛两种淡水蟹（甲壳纲、Brachyuna、Gecarcinucidae、太阳蟹）的描述

来自吕宋岛的鲜为人知的菲律宾淡水蟹Sundathlphusa picta（von Martens，1868）使用模式材料以及从其模式位置附近采样的其他标本进行了重新描述和说明。来自吕宋的两种类似同源物，分别来自巴丹省和里扎尔省的S.uva sp.nov.和S.angelito sp.nov..被描述为新的。这三个物种因其相对较小的体型、圆形和圆顶状的甲壳、按比例较短的活动腿和粗壮的雄性第一蜥脚类动物而结合在一起。它们通过一系列形态特征相互区分，特别是甲壳类、雄性类人猿和蜥脚类。
