Two new species of Motschulsky, 1858 (Coleoptera, Limnichidae, Limnichinae) from Negros, Philippines.

Two new species of Limnichidae beetles, and , are described from the Island of Negros in the Philippines. The adult specimens of the new species can be differentiated by patterns of body punctation, colour and orientation of elytral pubescence, posterolateral angle of pronotum, tarsomere length ratio and aedeagal form. Two clades, representing the two new species, were retrieved in the Maximum Likelihood gene tree using the 3'-end of the gene. Maximum genetic divergence within sp. nov. and sp. nov. were recorded to be 2.3% and 1.3%, respectively, while the mean interspecific divergence between the two new species was 19.7%. Morphological descriptions, digital photographs and sequences were provided for the two species. The state of knowledge of is reviewed and an updated Philippine checklist is provided. By coupling morphological and molecular data, this paper provides the first additional new species of Philippine in the last 28 years.
