Toskina I.N., New Species of the Genus Ptilineurus Reitter, 1901 (Coleoptera: Ptinidae: Eucradinae) from South-West Chinа // Byul. MOIP. Otd. biol. 2017. T. 122. Vyp. 3. S. 12-17

New Species of the Genus Ptilineurus Reitter, 1901 (Coleoptera: Ptinidae: Eucradinae) from South-West Chinа

The new species Ptilineurus sychuanensis sp. nov. is described from prov. Sychuan’. Beetles mainly black, elytra rufousish, 1st and 2nd antennomeres lighter, rufous. Pubescence fine, rare, dark grey. Body surface covered with granulation. Eyes separated by 2.6–3.0 diameters of an eye. Antennomeres serrate (♀) or with long rami (♂) from 3rd segment; ramulus of third segment is 1.7 times as long as its segment, ramulus of 4th segment is twice, 5th – 2.3 times, 6th and 7th – 3 times, 8th – about 3 times as long as their segments. (9–11 segments are lost). Pronotum 1.3 times as wide as long, strongly convex; anterior angles a little recurved under head. Basal margin with two notches. Scutellum large, rectangular, transverse. Elytra 1.5 times as long as wide and 2.3 times as long as pronotum, with 4 costae on each elytron. The 2nd costa on each elytron enters into notch of pronotal base. Elytral disc with strong transverse impression on each elytron. Elytral ends go down and cover a part of pygidium. Metasternum strongly convex and with median line. First tarsimere is 2.5 times as long as the 2nd one; 2nd tarsimere is a little longer than the 3rd one, 3rd and 4th tarsimeres are small; 5th tarsimere is nearly as long as the 2nd one. First abdominal suture curved backwards. Body twice as long as wide. Length 3.25–3.45 mm. The new species differs from P. marmoratus (Reitter, 1901) by short rami of antennal segments, trapeziform pronotum, 4 costae and strong transverse impression on each elytron, and by more long elytra. The new species differs from P. elegans (Fairmaire, 1895), P. pictipennis (Fairmaire, 1895), and P. sumatrensis Pic, 1907 by another color – without white spots. In addition, the new species differs from P. elegans by pronotal basal margin with two notches only whereas P. elegans has united in pairs notches on each elytron. P. sumatrensis has broad semicircular scutellum and obtuse gibbous pronotum whereas P. sychuanensis has rectangular scutellum and convex trapeziform pronotum.

We agreed with Españols’ opinion that the genus Ptilineurus belongs to subfamily Eucradinae by structure of antennae and genital apparatus.
