Ancyronyx Jhoanae Sp. Nov. (Coleoptera: Elmidae), A New Spider Riffle Beetle Species From Luzon, Philippines, And New Records For A. Tamaraw Freitag, 2013, Christalle Beatriz N. Seno, Hendrik Freitag Feb 2023

Ancyronyx Jhoanae Sp. Nov. (Coleoptera: Elmidae), A New Spider Riffle Beetle Species From Luzon, Philippines, And New Records For A. Tamaraw Freitag, 2013, Christalle Beatriz N. Seno, Hendrik Freitag

Biology Faculty Publications

Ancyronyx jhoanae sp. nov., a new species of genus Ancyronyx Erichson, 1847 from Luzon is described using an integrative taxonomic approach. Illustrations of habitus and diagnostic characters are provided. Molecular analysis of a fragment of the COI 5’-end was employed to support the morphological species concept. Differences from closely related species based on molecular and morphological data are discussed. First records of A. tamaraw Freitag, 2013 from Luzon are reported.


Two New Species Of Byrrhinus Motschulsky, 1858 (Coleoptera, Limnichidae, Limnichinae) From Negros, Philippines, Emmanuel D. Delocado, Hendrik Freitag Nov 2021

Two New Species Of Byrrhinus Motschulsky, 1858 (Coleoptera, Limnichidae, Limnichinae) From Negros, Philippines, Emmanuel D. Delocado, Hendrik Freitag

Biology Faculty Publications

Two new species of Limnichidae beetles, Byrrhinus negrosensis sp. nov. and Byrrhinus villarini 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 …


Taxonomic Revision Of Agraphydrus Régimbart , 1903 V. Philippine Species And Their First Dna Barcodes (Coleoptera: Hydrophilidae: Acidocerinae), Hendrik Freitag, Albrecht Komarek Sep 2020

Taxonomic Revision Of Agraphydrus Régimbart , 1903 V. Philippine Species And Their First Dna Barcodes (Coleoptera: Hydrophilidae: Acidocerinae), Hendrik Freitag, Albrecht Komarek

Biology Faculty Publications

The genus Agraphydrus RÉGIMBART , 1903 (Coleoptera: Hydrophilidae) of the Republic of the Philippines is taxonomically reviewed aided by COI mtDNA barcodes. Nine new species are described, all currently regarded as endemic to the Philippines: A. abrasus sp.n., A. ampullatus sp.n., A. batak sp.n., A. brevilobatus sp.n., A. occultus sp.n., A. palawanensis sp.n., A. pelingeni sp.n., A. tenuipalpis sp.n., and A. zetteli sp.n. Agraphydrus coomani (O RCHYMONT , 1927), widespread in the Oriental and Australasian regions, is recorded from the Philippines for the first time. COI sequences and thorough morphological examination suggest that this and further species represent a group …
