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

ABSTRACT: Two new species of Limnichidae beetles, Byrrhinusnegrosensis sp. nov. and Byrrhinusvillarini sp. nov., 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 COI gene. Maximum genetic divergence within B.negrosensis sp. nov. and B.villarini 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%.
