Abstract: Two new species of the genus Callimetopus Blanchard, 1853 (Coleoptera: Cerambycidae) from Luzon Island (The Philippines) are described and illustrated: C. anichtchenkoi sp. n. and C. shavrini sp. n. The genus now includes 38 described species.
INTRODUCTION
The genus Callimetopus Blanchard, 1853 (Coleoptera: Cerambycidae) is a long-horned beetle not well studied genus, which belongs to the species rich subfamily Lamiinae and tribe Pteropliini. Last revision, which includes 25 species of this genus and the key, was published by Breuning (1962). The key in Breuning (1962) included four species (C. principalis Heller, 1924, C. superbus Breuning, 1947, C. pulchellus Schultze, 1922 and C. gloriosus Schultze, 1922), which later were transferred by Vives (2005) to the genus Acronia Westwood, 1863.
In next years after Breuning (1962) 15 taxa of Callimetopus were described: C. paracasta Breuning, 1965, C. mindanaoensis Breuning, 1980, C. siargoanus mindanaonis Breuning, 1980, C. vivesi Breuning, 1981, C. longior Hudepohl, 1990, C. samarensis Vives, 2012, C. acerdentibus dela Cruz & Adorada, 2012, C. niveuseta dela Cruz & Adorada, 2012, C. stanleyi dela Cruz & Adorada, 2012, C. mindorensis dela Cruz & Adorada, 2012, C. cretumus dela Cruz & Adorada, 2012, C. pectoralis dela Cruz & Adorada, 2012, C. bilineatus Vives, 2015, C. danilevskyi Barsevskis, 2015, C. lazarevi Barsevskis, 2015 (Barsevskis et al (eds.) 2015). Later, two species of this list (C. mindanaoensis Breuning, 1980, C.
vivesi Breuning, 1981) were transferred to the genus Faustabryna Breuning, 1961 (Vives 2014). Dela Cruz & Adorada (2012) published key for 19 species of Callimetopus of the Philippines, and described genital structures for members of this genus for the first time.
Species of the genus Callimetopus are distributed in the Oriental region and was represented by 36 species: 30 species are known from the Philippine archipelago, C. rhombiferus (Heller, 1913) from Panay Island in the Philippines, 2 species (C. pantherinus Blanchard, 1853 and C. litturatus Aurivillius, 1926) from the Moluccas, C. nigritarsis Pascoe, 1865 from Moluccas and Malaysia, C. paracasta Breuning, 1965 from Borneo island, and 1species from Celebes and Malaysia. Barsevskis (2015c) described two new species (C. danilevskyi Basevskis, 2015 and C. lazarevi Barsevskis, 2015) of this genus and published new data about distribution of C. ornatus Schultze, 1934.
In recent years, the beetle fauna of the Philippine arcipelago has been intensively investigated. Over the last three years are published a lot of taxonomic papers with descriptions of new species of Cerambycidae from the Philippines (Vives 2012a, 2012b, 2013, 2014a, 2014b, 2015a, 2015b; Barsevskis 2013, 2014a, 2014b, 2014c, 2014d, 2015a, 2015b;2015c Barsevskis & Jaeger 2014).
In this paper two new species of the genus Callimetopus from the Luzon Island (Philippines) are described and illustrated. The genus now includes 38 described species. This study is a part of revision of the genus Callimetopus, which started in this year by me.
MATERIAL AND METHODS
The studied material is deposited in the beetles collection of Daugavpils University, Institute of Life Sciences and Technology, Coleopterological Research Centre (Ilgas, Daugavpils Distr., Latvia) (DUBC). All specimens have been collected in the Philippines by local collectors.
The laboratory research and measurements have been performed using Nikon AZ100, Nikon SMZ745T and Zeiss Stereo Lumar V12 digital stereomicroscopes, NIS-Elements 6D software,
Canon 60D and Canon 1 Ds Mark II cameras. The map of the Philippine archipelago (Fig. 1) have been drawn using the software ArcGis 10.
RESULTS Callimetopus anichtchenkoi sp. n.
(Fig. 2)
Type material. Holotype, female, Philippines, Luzon Isl., Mt. Province, 06.2013, local collector leg. (DUBC). General distribution: Philippines: Luzon Isl. (Fig. 1). Description. Body red brown, with very light luster and yellow brown pubescence, evenly covered surface of body. Length: 16.5 mm, width: 6.2 mm.
Head flat, wide, with almost parallel sides, with slightly convex eyes and slightly widened cheeks. Surface of head evenly covered with yellow brown pubescence, with sparse brown dots. Head between eyes and antennal bases with thin longitudinal keel. Labrum pubescent, with yellow brown hairs, which relatively longer than that on other parts of head. Clypeus brown, transverse, with light luster and long yellow brown pubescence. Mandibles glossy, slender, moderately narrow and sharp. Antennae red brown and relatively short, covered by dense yellow brown pubescence; 1st antennomere thickened, with sparse coarse brown punctures between pubescence; 3rd antennomere longer than 4th; remaining antennomeres brown, in anterior part slightly darkened.
Pronotum almost cylindrical, with acute basal angles, red brown, with yellow brown evenly covered pubescence, with coarse punctation. Basal part of dorsal disc of pronotum with distinct smooth middle line, reaching middle length of pronotum. Anterior ventro - lateral pair of spines sharp, extended. Antero - lateral humps of pronotum very small, almost unvisible. Scutellum small, rounded apically.
Elytra red brown, glossy, flattened dorsally, without visible humps behind shoulders, finely punctate. Basis of elytra concaved at shoulders. Entire surface of elytra evenly covered with yellow red pubescence. Each elytron behind middle with slightly visible unclear
narrow pale line and with several small pale spots with similar pubescence. Apical part of elytra along suture with narrow flat keel-shaped elevation. Apex of elytra rounded, without visible projections, with many long hairs.
Bottom side of body covered with dense yellow brown pubescence. Legs red-brown, slightly glossy, covered with red-brown and brown dense pubescence. Tarsomeres brown, covered with pale pubescence.
Differential diagnosis. The new species differs from other described species of the genus Callimetopus by red brown coloration of body and yellow brown pubescence, which evenly covered the surface of body. Other Callimetopus species with different coloration of the body and another features of the pubescence.
Etymology. This species is named after my colleague and friend, carabidologist Alexander Anichtchenko (Daugavpils, Latvia) in appreciation of cooperation and support.
Callimetopus shavrini sp. n.
(Fig. 3)
Type material. Holotype, female, Philippines, Luzon Isl., Sierra Madre, Quirino, 06.2013, local collector leg. (DUBC). General distribution: Philippines: Luzon Isl. (Fig. 1). Description. Body black, with light luster and white pubescence, unevenly distributed on surface of body. Length: 21.8 mm, width: 7.5 mm.
Head flat, wide, with almost parallel sides, with slightly convex eyes and slightly widened cheeks. Surface of head, except anterior part, with uneven white pubescence, with sparse black dots. Head between eyes and antennal bases with thin longitudinal keel. Labrum with brown and pale pubescence. Clypeus red brown, transverse, with light luster. Mandibles glossy, curved inwards apically, sharp. Antennae black and short. First antennomere thickened, with white uneven pubescence and dense coarse punctures; 3rdantennomere longer than 4th, with light white pubescence basally; remaining antennomeres black.
Pronotum almost cylindrical, with acute basal angles, black, with white uneven pubescence, with sparse and coarse punctation.
Anterior parts of dorsal disc of pronotum smooth, with indistinct black spot, without pubescence. Anterior ventro - lateral pair of spines sharp, extended. Antero - lateral humps visible, slightly extended. Scutellum small, with line of dense white pubescence laterally.
Elytra black, glossy, flattened dorsally, with small slightly visible humps behind shoulders, finely punctate. Basis of elytra concaved at shoulders. Entire surface of elytra unevenly covered with white pubescence (some places of elytral pubescence of holotype loss). Each elytron with two irregular black smooth spots, without pubescence: first spot located at shoulder area, second spot in apical part of elytra. Apical part of elytra along suture with narrow flat keel-shaped elevation. Apex of elytra subtruncate, with visible projections and with many long hairs.
Bottom side of body covered with dense white pubescence, with small black dots. Legs black, slightly glossy, covered with pale dense pubescence,with black small spots. Tarsomeres black, covered with pale and black pubescence.
Differential diagnosis. The new species differs from other species of the genus Callimetopus by white unicoloured pubescence, which unevenly covered the surface of body.Pubescence of other species different, it is often bicoloured.
Etymology.This species is named after my colleague and friend, staphylinidologist Alexey Shavrin (Daugavpils, Latvia) in appreciation of cooperation and support.
