Abstract: Two new species of the genus Callimetopus Blanchard, 1853 (Coleoptera: Cerambycidae) are described and illustrated: C. antonkozlovi sp. n. (Philippines: Leyte, Luzon, Mindanao and Samar islands) and C. juliae sp. n. (Philippines, Luzon). New records for C. variolosus (Schultze, 1920) and C. albatus (Newman, 1842) are given. The genus now includes 39 described species, which are distributed in the Philippine archipelago, Moluccan archipelago, Indonesia and Malaysia.
INTRODUCTION
In recent years, the long-horned beetle (Coleoptera: Cerambycidae) fauna of the Philippine archipelago has been intensively investigated. Over the last four years a lot of taxonomic papers with descriptions of new species or new records from the Philippines are published (Barsevskis 2013, 2014a, 2014b, 2014c, 2014d, 2015a, 2015b, 2015c, 2015d, 2015e; Barsevskis, Jaeger 2014; dela Cruz, Adorada 2012; Miroschnikov 2015; Vives 2012a, 2012b, 2013, 2014a, 2014b, 2015a, 2015b). Recently, nine new species of Callimetopus were described (Barsevskis et al. 2016).
In last year author published three articles (Barsevskis 2015c, 2015d, 2015e) on the genus Callimetopus and described five new endemic species from the Philippine achipelago, of which four species are found on the Luzon Island and one on the Mindanao Island.
In the present study two new species of Callimetopus are described and illustrated, one of which is closely related to C. variolosus (Schultze, 1920), and other is very similar with
C. albatus (Newman, 1842) from Luzon island. Besides that, new faunistic data for C. variolosus and C. albatus are presented and type material for both species are studied. The genus Callimetopus now includes 39 described species.
MATERIAL AND METHODS
The material from the following collections has been examined:
AKC - Anton Kozlov private beetles collection (Moscow, Russia);
DUBC - Daugavpils University, Institute of Life Sciences and Technology,
Coleopterological Research Centre (Ilgas, Daugavpils Distr., Latvia);
BMNH - The Natural History Museum (London, UK);
SMTD - Senckenberg Natural History Collections Dresden, Museum of
Zoology (Dresden, Germany).
The type specimens of new described species are deposited in 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, and Canon 60D and Canon 1 Ds Mark II cameras.
The maps of the Philippine archipelago have been drawn using the software ArcGis 10 and Bing Map Areal (Source: Esri, DigitalGlobe, GeoEye, Earthstar Geographics, CNES/Airbus DS, USDA, USGS, AEX, Getmapping, Aerogrid, IGN, IGP, svvisstopo, and the GIS User Community; Image courtesy of NASA Earthstar Geographics SIO © 2016 Microsoft Corporation).

Frontal part of dorsal disc of pronotum without pubescence, smooth, with brown pubescence and sparse, small dark spots in lateral part. Anterior ventrolateral pair of spine robust, blunt, visible. Pars stridens bilobate, with wide rounded apex and very fine transverse, reticulate microsculpture and with several sparse punctures. Scutellum small, rounded apically, with dense brown pubescence.

Differential diagnosis. In general appearance of the body, the new species is similar to C.
variolosus (Schultze, 1920) (Fig. 1B, F, H), but differs from this species by some differences in coloration and shape of the aedeagus.. The body surface of C. antonkozlovi sp. n. covered with a lot spots of brown pubescence, while the surface of C. variolosus covered by white pubescence and with irregular spots of yellow - brown pubescence between it. Antennomeres 4th-6th and basal part of 7th antennomeres of C. antonkozlovi sp.n. with dense white pubescence, while C. variolosus are with very sparse white pubescence of these antennomeres (Fig. 1E, 1F). The aedeagus of C. antonkozlovi sp.n. more evently curved and more robust than that of C. variolosus. The lamella of C. antonkozlovi sp.n. more widely rounded and more tilt up as in C. variolosus.
Etymology. This species is named after my colleague, entomologist Anton Kozlov (Moscow, Russia) in appreciation of cooperation.
