Two new Elmidae species from the Visayan island of Negros, Philippines, Ancyronyx berghaueri sp. n. and Ancyronyx negrosensis sp. n., are described utilizing an integrative taxonomic approach. The new species are characterized by the color of the femora, body size, and the male and female genitalia. Their habitus and diagnostic characters are described and illustrated in detail with microscopic images and digital line drawings. The morphological species delimitation is supplemented by and congruent with COI and cob mtDNA data of several known species of Ancyronyx from the Philippines and Borneo. The material was obtained in connection with a student thesis, the sampling program of the Ateneo de Manila University Biodiversity Laboratory and from repositories. Specimens were collected at altitudes between 30 m and 800 m above sea level in pristine and slightly disturbed habitats. Their suitability as bioindicators and the use of cob sequences for integrative taxonomic studies are briefly discussed

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.
