INTRODUCTION
The genus Polyphida Pascoe, 1861 (Coleoptera:
Cerambycidae) belong to the subfamily Ceram-
bycinae and tribe Glaucytini. Prior to the present
study, the world fauna of Polyphida presented
by 14 species. Four species, P. argenteofasciata
Aurivillius, 1910, P. clytoides Pascoe, 1869, P.
fulvitarsis Holzschuh, 2005 and P. tenebrosa
Holzschuh, 2005 are endemics of Borneo. Two
species, P. lumawigi Hüdepohl, 1992 and P.
monticola Heller, 1915 are endemics of the Phi-
lippine archipelago. Two other species, P. buru-
ensis Breuning, 1970 and P. lombokiana Vives,
2013 are endemics of the Moluku Islands. Three
otherspecies are also endemics: P. aurata Vik-
tora, 2015 for Sumatra, P. jakli Viktora, 2019
for Sulawesi, and P. hayashii Viktora, 2015 for
Perak, Malaysia. Only two species have more
wide distribution in the Oriental Region: P. mo-
desta Gahan, 1906 known from Borneo, Sumatra,
Java, W Malaysia, and P. metallica (Nonfried,
1894) from India, Burma, Laos and Thailand
(Victora, 2015; Tavakilian, Chevillotte 2021).

It is important to note, that half of species of
the genus have been described in the last thirty
years (Huedepohl 1992; Holzschuh 2005; Vives
2013; Viktora 2015, 2019).
The review of the genus Polyphida of the fauna
of the Philippines has been published by Hüde-
pohl (1992), where, analyzing the species of
Callichromatini, Clytini and Glaucytini of the
Philippines, he recorded two species for the
archipelago, including one new species. In this
paper he has also provided a key for two species
found of the Philippines.
In this article, authors provided descriptions of
three new species,a key for all four Philippine
species of this genus, and new faunistic records
for P. monticola and P. lumawigi. The provided
information for P. lumawigi is the first published
faunistic data after the original description of
this species.
MATERIAL AND METHODS
The studied material is deposited in the beetles
collection of Daugavpils University, Institute of
Life Sciences and Technology, Coleopterolo-
gical Research Centre (DUBC; Ilgas, Daugav-
pils Distr., Latvia).
The laboratory research and measurements have
been performed using Nikon AZ100, Nikon
SMZ745T and Zeiss Stereo Lumar V12 digital
stereomicroscopes, NIS-Elements 6D software.
The habitus photographs were obtained with a
digital camera Canon EOS 6D with Canon MP-
E65 mm macro lens, using Helicon Focus auto-
montage and subsequently was edited with
Photoshop. All measurements are given in milli-
meters.
In the present paper, we followed the taxonomic
nomenclature provided by Tavakilian, Chavil-
lotte (2021).

slightly constricted after second third and before
apical margin: opaque, densely and finely
punctate, with silver-grey pubescence. Middle
portion of pronotal disc with sparse punctation
or without punctures, with long or short and
smooth midline. In some specimens this midline
may be rudimentary or very indistinct.
Scutellum small, semicircular, with pubescence

stridens with very fine transverse microsculp-

Elytra subparallel, narrowed in apical quarter,
apically truncate, with acute small sutural and

coarsely punctate in basal portion, finer and
irregularly in preapical; each puncture with fine
silver-grey seta, in apical quarter with semierect
hairs. Elytra with five bands of silvery tomen-
tum. Basal band enlarged at shoulders and along
suture connected with anteriomedial transverse
band, the latter joined with another transverse
band in posterior third and further rounded
toward apex. Ventral surface of body with dense
pubescence, with sparse, short, erect pilosity.
Legs with very fine, silvery white pubescence
and several erect hairs. Some specimens have
silver grey pubescence with somewhat golden
lustre.
The aedeagus is damaged.
Differential diagnosis. For determination of
this species, see the key below.
Etymology. The name of this species is derived
from the name of the island where this species
was collected.
Habitat. The new species was collected on the
junction between a primary forest and secondary
forest at an elevation of 1100 m asl (Fig. 7).
Some portions of the land were cleared to be
planted by tiger grass as part of the livelihood
of the Bagobo-Klata living in the area. The plant
where the new species was collected has not
been identified.
