Ancyronyx lianlabangorum sp. nov. (Coleoptera, Elmidae), a new spider riffle beetle from the Kelabit Highlands (Sarawak, northern Borneo), is described. Illustrations of the habitus and diagnostic characters of the new species and the similar, polymorphic A. pulcherrimus Kodada et al. are presented. Differences to closely related species, based on COI nucleotide sequences and morphological characters, are discussed.\ Ancyronyx pulcherrimus is here recorded from Sarawak for the first time, based on DNA barcoding.

Ancyronyx montanus sp. n. is described based on adults and larvae, matched using their cox1 DNA sequence data. Larvae of six additional species of Ancyronyx Erichson, 1847 were also described here for the first time, aided by cox1 or cob data: A. helgeschneideri A. helgeschneideri Freitag \& J\äch, 2007, A. minerva Freitag \& J\äch, 2007, A. patrolus Freitag \& J\äch, 2007, A. procerus J\äch, 1994, A. punkti Freitag \& J\äch, 2007, A. pseudopatrolus Freitag \& J\äch, 2007. Ancyronyx procerus is newly recorded from the Philippines by a larval specimen from Busuanga island. The new species and larval stages are described in detail and illustrated by digital and SEM images. A key to the Ancyronyx larvae of Palawan and an updated checklist of Philippine Ancyronyx is provided.

Ancyronyx buhid sp. n. and A. tamaraw sp. n. are described based on adults and larvae, matched using their cox1 or cob DNA sequence data. Additional records of A. schillhammeri J\äch, 1994 and A. minerva Freitag \& J\äch, 2007 from Mindoro are listed. The previously unknown larva of A. schillhammeri is also described here, aided by cox1 data. The new species and larval stages are described in detail and illustrated by SEM and stacked microscopic images. Keys to the adult and larval Ancyronyx species of Mindoro and an updated checklist of Philippine Ancyronyx species are provided. The usefulness as bioindicators, the phylogenetic relationships and biogeographic aspects affecting the distribution patterns are briefy discussed.
