A new tiger beetle species (Coleo ptera: Cicindelidae)
from Palawan Island, Philippines
Jürgen Wiesner
Abstract
Cylindera (Ifasina) kerkeringi sp.n. is described from Palawan Island. It can be distinguished
from the other species of the subgenus Ifasina by the colour pattern of the elytra, the shape
of the elytral apex, and the shape of the aedeagus.
Keywords. Cylindera, Ifasina, new species, diagnosis, key, species list, Philippines,
Palawan.
Zusammenfassung
Cylindera (Ifasina) kerkeringi sp.n. wird von der Insel Palawan beschrieben. Sie kann
von den anderen Arten der Untergattung Ifasina durch das Farbmuster der Flügeldecken,
die Form des Flügeldecken-Apex und die Form des Aedeagus unterschieden werden.
Introduction
Twenty-two taxa of tiger beetles are currently reported from Palawan Island (Wiesner
2020), ve of which are endemic (Tab. 1).
A recent identication consignment from Mr. Christian Kerkering included specimens
that supercially resembled Cylindera (Ifasina) discreta elaphroides (Dokhtouroff, 1882)
but on closer examination turned out to be a new species, which is described herein.
Material and methods
All measurements were taken using a stereomicroscope Motic SMZ-171. Measurements
of total body length were taken from the front of the clypeus to the apex of the elytra.
The label data of type specimens were collated using the following system: in order from
pinhead to pin point the label data were copied with label lines. Printed white labels and
rectangular shape, however, were not explicitly noted. All remaining pertinent data were
recorded within brackets.

D i a g no s is . Labrum short, with dark brown margins. Elytra with basal lunule, middle
band incomplete; with two darkened areas, one around the discal spot and another near
the apical end of the humeral lunule; elytral apex restricted towards middle suture, sutural
spine bent upwards in females. Aedeagus slender and curved towards apex, not tapered
into a point.
D e s c r i pt i on . Size: Total length (without labrum) 6.7–7.1 mm (mean = 6.9 mm, n = 7).
Head: Above black coppery, with minute green and coppery spots, genae likewise, clypeus
red coppery; above very nely granulate, glabrous, with two setigerous punctures next to
each of the eyes in front and at the centre; strong longitudinal striae on orbital plates and
genae, the striae becoming less strong to extinct on vertex, and irregular, transversely
waved behind eyes and at the back of neck; genae with scattered white setae. Ratio of head
width to elytra width = 1.3 on average. Labrum (Figs 6, 7) yellowish with darker lateral
margin, ver y much wider than long, ratio of width to length = 2.2 on average; with eight
to ten marginal setae and three protruding apical teeth, the middle one acute-angled and
longer than the obtuse-angled outer ones. Mandibles dark, with green metallic lustre, outer
ba se yellowish . Labial and ma xil lar y palpi yellow ish, th e la st joi nt meta llic gr een ish; basa l
segment of labial palpi with long erected white setae. Antennae slender, long, reaching
half of the elytral length in the males, a little shorter in the females; antennomeres one
to four metallic green, with coppery lustre; scape with one long apical seta, the other
three antennomeres with scattered white setae; antennomeres ve to eleven blackish,
dull, nely and evenly pubescent. Thorax: Pronotum as wide as long (ratio of width to
length = 1.0), with shallow transverse furrows; sides between transverse constrictions
barely rounded; lateral margin sparsely pubescent with white setae; anterior transverse
constriction shallower than posterior; black coppery, with minute green and coppery spots.
Sternae, episternae and coxae coppery, coxae with white setae, scattered white setae on
metepisternum, the remaining glabrous. Mesepisternum of females (Fig. 8) with a large
roundish dimple in the upper half. Elytra: (Figs 2–5) longer than wide, ratio of width to
length = 1.5 on average, parallel-sided, slightly widened in the middle, tapered towards the
front in females; black coppery, with minute green and coppery spots, covered with large
green pits throughout, with two darkened areas, one around the discal spot and another
near the apical end of the humeral lunule. Elytral testaceous maculation consisting of a
thin humeral lunule, a large triangulate marginal dot, a large roundish central dot, a large
roundish antiapical dot, and a thin apical line. Apical microserration ne; apical border
(Figs 9, 10) distinctly rounded and restricted towards middle suture, shortly restricted in
males ending in a tiny sutural spine, largely restricted in females with a long sutural spine
bent upwards. Epipleura yellowish. Ventral aspect: venter setose, covered throughout with
white setae, cupreous, with green lustre. Trochanters yellowish; femora, tibiae, and tarsi
metallic green with cupreous lustre; legs covered with white setae. Aedeagus (total length
2.8 mm on average): on left lateral view (Fig. 11) slender, slightly thickened towards apical
third, then again narrower but not tapered, curved ventrally, with blunt tip.

E t y m ol o g y. This new species is named after the German tiger beetle collector Christian
Kerkering, who provided the type specimens.
Remarks
It should be noted that elaphroides Dok htouroff, 1882, presently placed within Cylindera
(Ifasina) discreta (schauM, 1863) as a subspecies, is likely more appropriately elevated
to a full species rank. However, to denitively clarify this, the type specimens of both
taxa must be examined. It cannot be excluded that more cryptic species are among the
specimens previously determined as C. discreta and elaphroides in collections.
