Abstract
Phyllocladus kascmtsevi, a new species of fire-colored beetle, is described from four males and four females taken from mountainous regions of southern Gansu and Shaanxi provinces in east-central China. All specimens were collected between 9 June and 12 August at elevations ranging from 1300–2600 meters.
This is the second described Phyllocladus from China, the other being Phyllocladus grandipennis (Pic, 1906), and the fifth species attributed to Phyllocladus. The three remaining species are Phyllocladus magnificus (Blair, 1912) of Myanmar, Phyllocladus costatus Pic (1914) known from Vietnam, and Phyllocladus brevior Pic (1927), also from Vietnam. Salient features of the males, including the elongate head, distinctive cranial pits, enlarged compound eyes, long antennal pedicel, strongly lamelliform branches of the antennal flagellum, and abdominal terminalia clearly place the new species in Phyllocladus. The crest-like or hooded forward extension of the vertex, thus partially concealing the posterior cranial pits, easily distinguishes it from P. grandipennis.
