( Fig. 6 ) Type material. Holotype , female : ‘’ Philippines , Mindoro Isl. , Mt. Halcon , III. 2014 , local collector leg.’’ (typed with a white card); [ex. Prof. A. Barševskis coll.] (typed with a white card); ‘’HOLOTYPE / Pachyrhynchus domino / Rukmane 2016 / det. Rukmane 2016 ’’ (typed with a red card) ( DUBC ) . Distribution: Philippines , Mindoro Island. Description. Measurements: LB: 14.3; LE : 8.4; WE: 5.9; LP : 3.4; WP: 3.6; LR: 1.8; WR: 1.6. Habitus dorsally as in Fig. 6B ; laterally as in Fig. 6E . Body and legs black, shiny; body surface with pale orange and yellow scales. Head black, shiny, with sparse, fine punctation under each eye. Eyes strongly convex, black. Head between eyes without longitudinal band or spot of pale scales. Laterar sides of rostrum with pale scales, with long apical setae. Apical bulge of rostrum flattened, with fine punctation. Rostrum in basal half with oblong depression and strong median groove.Antenna black, with small antennomeres. Pronotum subspherical, slightly flattened, widest in middle, with very fine, sparse punctation, on basal and apical margin of pronotum with six triangular shape spots of yellow to orange pale scales, two median triangular spots of apical margin blended. Elytra with two blended median spots, each elytron with two transverse and two longitudinal stripes forming frame of pale yellow and orange scales: 1) transverse stripe close to basal margin of elytra; 2) longitudinal stripe from interval II to interval III ; 3) flat longitudinal stripe from interval V to lateral margin, with lack of scales at median portion from interval VI to lateral margin; 4) transverse stripe at apical margin. Median part of each elytron with two spots, one more dorsally, one more laterally. Intervals of elytra smooth, with fine punctures between not impressed rows. Legs very thin, with strong clavate femori. Tibiae incurved apically. Middle and hind femori thinly covered with short setae and scales along posterior margins. Tibiae with sparse pubescence, mingled with long setae. Tarsomeres black, covered with sparse brown pubescence. Scutellum small, apically rounded. Male unknown. Differential diagnosis. Pachyrhynchus domino sp. n. is similar in general appearance to P. pseaudhalconensis sp. n. and P. halconensis , wich has different pattern of elytra and shape of female genetalia which is longest and narrowest. Elytral differences appear in Fig. 6 A-F. P. domino sp. n. 1) lack of scales on head between eyes; 2) eyes more convex; 3) legs more thin; 4) deeper median groove; 5) more shallow impression on dorsal side of rostrum; 6) rostrum is more narrow and lower edge is less extended. Etymology. The name of the new species is derived from the unical scale margins forming domino tile with two spots on each elytron.
