Two new species of the genus Glenea Newman, 1842 (Coleoptera: Cerambycidae: Lamiinae: Saperdini) from Mindanao and Luzon Islands Philippines
Abstract
We describe and illustrate two new species of Glenea Newman, 1842 from the Philippines: G. barsevskisi sp. nov. and G. vitali sp. nov. Both species belong to the subgenus Glenea sçnsű strictô. At present, the total number of Glenea species in the Philippines is 89 (79 species and 10 subspecies).
... Among the 17 megadiverse countries in the world (Catibog-Sinha and Heaney 2006;Heaney and Regalado 1998;Myers et al. 2000), the uniqueness of Philippine biodiversity has always risen as one of the top fascinating biogeographic areas for biodiversity researchers worldwide (Barševskis 2017(Barševskis , 2018(Barševskis , 2021Barševskis et al. 2020Barševskis et al. , 2022aBarševskis & Medina 2021;Botero & Vives 2021;Medina et al. 2021Medina et al. , 2022Medina et al. , 2023Vitali 2013Vitali , 2016Vitali , 2019Vitali & Chemin 2022;Vitali & Gouverneur 2022;Vives 2005Vives , 2009Vives , 2013aVives ,b, 2014Vives , 2015aVives ,b, 2017Vives , 2021Vives & Trócoli 2022). The high species diversity of the Philippines can be accounted for by its unique biogeographic origin (Catibog-Sinha and Heaney 2006;Heaney & Regalado 1998;Medina et al. 2020, Mendoza et al. 2020, its position at the Wallaceae (Vallejo Jr. 2011;Vane-Wrigth 1990), and its tropical condition (Catibog-Sinha & Heaney 2006). ...
... In the past two decades, there has been an increase in activity on the taxonomic work of Philippine beetles, particularly in the family Cerambycidae (long-horned beetles) (Barševskis 2017(Barševskis , 2018(Barševskis , 2021Barševskis et al. 2020Barševskis et al. , 2022aBarševskis & Medina, 2021;Botero & Vives, 2021;Medina et al. 2021Medina et al. , 2022Medina et al. , 2023Vitali 2013Vitali , 2016Vitali , 2019Vitali & Chemin, 2022;Vitali & Gouverneur 2022;Vives 2005Vives , 2009Vives , 2013aVives ,b, 2014Vives , 2015aVives ,b, 2017Vives , 2021Vives & Trócoli, 2022). Of the roughly 7,000-8,000 species of described beetles in the Philippines (Baltazar, 2001), approximately 1,100-1,500 (around 16-19%) of them are long-horned beetles making it the biggest family in Philippine Coleoptera fauna (Vives & Cabigas 2015). ...
... The genus Cyriotasiastes (Newman 1842), is a group of long-horned beetles under the sub-family Lamiinae (flat-faced beetles) distinguished by their unique three bands of whitish pubescence in elytra, with a slight hump at the pronotal disc, two-toned (white and black band of pubescence) antennomeres III to VI or in antennomeres III to VIII, and strongly recurved aedeagus with pointed apex. At present, the genus is considered monotypic and represented by four sub-species, C. rhetenor rhetenor (Newman 1842), C. rhetenor solsonanensis Medina et al. 2023, C. rhetenor panayensis Barsevskis, 2018, and C. rhetenor mindorensis Vives 2009. The present distribution of the genus is the Philippines with 4 sub-species, and 1 in Borneo, C. r. rhetenor. ...
The genus Cyriotasiastes (Neman, 1842) is revised using a combination of morphological, biogeographic, and molecular data. Based on this, we proposed to erect the four species belonging to sub-species Cyriotasiastes rhetenor: C.rhetenor
rhetenor, C. rhetenor mindorensis, C. rhetenor panayensis, C. rhetenor solsonanensis, as separate species with the following statuses: Cyriotasiastes rhetenor (Newman, 1842) stat. nov., C. solsonanensis Medina et al., 2023 stat. nov., C. mindorensis Vives, 2009 stat. nov., C.s panayensis Barševskis, 2018 stat. nov. A new species Cyiotasiastes mindanaonis sp. nov. is also described, this is the first record in Mindanao Island and the fifth species for the Philippine fauna. A key
to the species in the Philippines is also provided.
... Most of them are congeneric to species found in the Malay peninsula, Indonesian islands, and greater Southeast Asia, being attributed to the biogeographical resemblance of these regions (Hüdepohl 1990). With roughly 1500+ species of Cerambycidae in the Philippines (Medina et al. 2023;Roques 2023), hundreds more are expected to be discovered, particularly in the subfamily Lamiinae including members of the tribe Apomecynini. The Apomecynini is comprised of 1821 species (Roques 2023), many of which require revision given the scanty data on species taxonomy and distribution. ...
This paper introduces Bityle oriens sp. nov. (Coleoptera: Cerambycidae: Lamiinae: Apomecynini) from Boston, Province of Davao Oriental, Philippines. A catalog of the known species of the genus Bityle is also presented. Coleoptera expeditions need to be undertaken to discover more novel species, especially in the understudied islands of the Philippine archipelago.
... The Cerambycidae fauna in the Philippines is still greatly understudied (Barševskis et al., 2020;Barševskis et al., 2022a, b;Medina et al., 2020Medina et al., , 2021aMedina et al., ,b, 2022Medina et al., , 2023 particularly those taxa that are rarely collected in the field. Hence, it is expected that when more field expeditions are conducted, more species will be introduced as new to science for Philippine fauna. ...
This paper describes Paraskeletodes hamiguitanensis sp. nov., the second species of the genus Paraskeletodes Aurivillius 1972 (Coleoptera: Cerambycinae: Phoracanthini) in the world. This rare species was found in Mt. Hamiguitan Range
Wildlife Sanctuary (MHRWS), a UNESCO World Heritage Site in the Province of
Davao Oriental, Mindanao Island, Philippines. The discovery of this species
emphasizes the need to strengthen and expand wildlife conservation efforts in Davao Oriental, Philippines.
Doliops comvalensis Medina, sp. n. is described from Candalaga Range in Maragusan, Davao de Oro, Mindanao, Philippines. High-definition images of other known species of Doliops which are considered as the close congeners of the new species are also provided. The mimicry complex between the new species and the members of the tribe Pachyrhynchini known from Candalaga Range is discussed.
A new species of Callimetopus Blanchard, 1853, C. dagtumanus sp. nov. is described and illustrated. This is the first species of Callimetopus in Mt. Candalaga range in Maragusan, Davao de Oro Province, and the first for Eastern Mindanao Biodiversity Corridor, Philippines. A short note on the species ecology and images of known Callimetopus species in Mindanao is also presented.
This article provides new distribution records of the twenty seven species of the genus Anoplophora in Asia based on the beetle collection at the Coleopterological Research Center of Daugavpils University, Latvia. Anoplophora zonator (Thoms.) is recorded for the first time in Vietnam. In the Philippines, the following distribution records are newly set, A. tianaca (Schultze) in Negros island, A. sebastieni
Duranton) in Luzon island, an additional data since its species description, and A. asuanga (Schultze) in Leyte and Samar islands.
A catalog of the genus Cylindrepomus Blanchard, 1853 in the Philippines, along with the description of a new species from northern Mindanao, is presented. Notes on the ecology, threats, and conservation of the new species are also provided.
The catalogue of the genus Cereopsius Pascoe 1857 fauna of the Philippines is provided, with description of a new species, C. erasmus sp. nov. from Mindanao Island. Additional taxonomic and faunistic notes on the other Philippine species are added.
A comprehensive and updated catalog of the genus Glenea Newman, 1842 is presented with the key to the sub-genera for Philippine species. The genus counts 87 species (77 species and 10 subspecies), ranged in seven subgenera. Glenea caraga invittaticollis Breuning, 1966 rest. status = Glenea caraga subvittaticollis Breuning, 1968 n. syn. (un. repl. nom).
The Philippine archipelago's position in Wallacea has been a matter of debate and is a biogeographic problem that has never been fully settled. In the current review this problem is examined in light of comparative phylogenetic biogeography, tectonic history and panbiogeography. The information about these supports Dickerson et al. (1928) assertions on the faunal transition character of Wallacea and how this defines the biotic regions of the Philippines within Wallacea and its links with Sulawesi. There is a need to go beyond the Pleistocene paradigm in Philippine biogeography if a fuller understanding of the scale and dimensions of biodiversity in the Philippines is to be achieved.
Eight species of Glenea Newman, 1842 from the Oriental Region are studied, including description of three new species: G. paradiana Lin et Montreuil sp. nov. from Vietnam & Laos, G. nigrorubricollis Lin et Yang sp. nov. from Guangdong, China and G. subrubricollis Lin et Tavakilian sp. nov. from Vietnam. Glenea theresae Pic, 1943 is regarded as a junior synonym of G. diana Thomson, 1865, and G. (Mesoglenea) invitticollis Breuning, 1956 as a junior synonym of G. flavorubra Gressitt, 1940. Glenea rufipes Gressitt, 1939 is reinstated from synonym of G. subsimilis Gahan, 1897. Habitus and terminalia are presented as photographs.
A new saperdine species belonging to a new genus, Tsounkranaglenea hefferni gen. et sp. nov., is described from Sabah, Malaysia. The new genus differs from other genera of the tribe Saperdini by the special male sternite VII modified into a rake-shape, with the apex of the ventral plate of the median lobe unusually emarginated.
