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.

The PJSB is a CHED recognized journal under CHED CMO 50 series of 2017. It is also included in the Clavariate Analysis (formerly a subsidiary of Thomson Reuters) Master Journal List under Zoological Record, BIOSIS Previews and Biological Abstracts.The PJSB is the official publication of the Association of Systematic Biologists of the Philippines (SEC Registration: Association of Philippine Taxonomists, Inc.). The organization financially supports the journal and all its endeavors. The journal aims to build up quality information on animal, plant and microbial diversity in the Philippines. Articles dealing with original research or reviews in Zoological, Botanical or Microbial Systematics, Ecology and Conservation Biology are welcome. Authors are advised to consult a recent issue of PJSB for the current format and style. All manuscripts are reviewed by at least two qualified referees.
