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
