Prof. A. Barševskis coll.] (all in DUBC ). All paratypes with additional red rectangular printed label: ‘’ PARATYPE / Pachyrhynchus tikoi / Rukmane 2016 / det. Rukmane 2016 ’’. Distribution: Philippines , Mindanao Island. Description. Measurements: (n=5; 3 males , 2 females ): LB: 12.5 (mean 13.3); LE : 6.5 (mean 7.3); WE: 4.4 (mean 5.0); LP : 3.2 (mean 3.4); WP: 3.0 (mean 3.2); LR: 1.4 (mean 1.6); WR: 1.5 (mean 1.6). Body and legs copper red to brown; body surface very glossy, with yellow, orange or green scale lines. Eyes, antennae and tarsomeres black. Latereal sides of rostrum covered with small oval scales, apical part of rostrum with elongate orange to yellow scales. Apical and basal margin of pronotum with impressed transverse band of orange scales, connected latteraly and forming frame shaped scale pattern. Transverse band in middle portion of apical margin of pronotum with small longitudinal keel. Apical part of femori with irregular orange to yellow scally spots. Each elytron with nine longitudinal orange, pale yellow and pale green narrow scale lines: 1) from basal margin of interval II till apical margin, not connected with rest of scale lines; 2) till ninth scale line from interval III till lateral sides of elytra, second and ninth, third and eighth scale lines connected at apical margin, fourth and seventh, fifth and sixth scale lines connected from both apical and basal margins. Habitus as in Fig. 1 (dorsally - Fig. 1A and laterally Fig. 1B ). Head with groove-shaped impression between eyes and two scale lines, forming V shaped pattern. Eyes large, strongly prominent if see dorsally, with band of orange scales on genae. Rostrum with very fine sparse pubescence, covered by brown sparse apical setae, with shallow impression in basal half weakly bulging apically. Apical bulge of rostrum flattened dorsally, with fine impression in middle part; dorsal part of rostrum interrupted by strong transverse groove.Antennal scape short and stout; remaining antennomeres small, with sparse very short pubescence and long setae. Pronotum subspherical, widest in middle. Elytra with short pubescence; intervals of elytra flattened, with coarse punctures in slightly impressed rows. Legs wide, with strongly clavate femori. Female legs more wider than in males. Tibiae serrate along internal margins, weekly curved apically. Middle and hind femori thinly covered with short setae and hair-like scales along posterior margins. Tibiae with sparse pubescence and long setae. Tarsomeres covered by sparse pale pubescence. Aedeagus relatively short, curved in lateral view ( Fig. 1D ). Lamella semicircular, rounded apically ( Fig. 1E, D ). Fig. 1. Habitus of Pachyrhynchus tikoi sp. n. : dorsal (A) and lateral (B) view; D, E: aedeagus of P . tikoi : lateral (E) and dorsal view; C: habitus of Doliops valainisi Barševskis 2013 , dorsal view. Mimicry. Pachyrhynchus tikoi sp. n. is mimics a longhorn beetle Doliops valainisi Barševskis 2013 , with which it co-exists ( Fig. 1C ). Differential diagnosis. Pachyrhynchus tikoi sp. n. resembles P. eques Heller, 1912 , which was described from Luzon Island, but Pachyrhynchus tikoi sp. n. is unable to be confused with P. eques by following points: coloure of body which is glossy red; shape of elytra which is narrower. Etymology. The new species is named after my life partner Marcin Tiko (Warsaw, Poland ), in appreciation of support, help and valuable advices during the research.
