Key words: Cerambycidae, Prioninae, taxonomy, new genera, China. Abstract: Two new genera are described: Unilaprionus gen. nov. - type species: Prionus unilamellatus Pu, 1987 and Plumiprionus gen. nov. - type species: Prionus boppei Lameere, 1912. Males and females of Unilaprionus unilamellatus (Pu, 1987) comb. nov., Plumiprionus boppei (Lameere, 1912) comb. nov. and Plumiprionus plumicornis (Pu, 1987) comb. nov. are figured.
The system of Prioninae genera of China fauna is not studied completely up to now. A publication of Cerambycidae type specimens deposited in National Zoological Museum of China (Lin, 2015) shows that poorly known Prionus unilamellatus Pu, 1987 and P. plumicornis Pu, 1987 have no connection with genus Prionus Geoffroy, 1762 and in reality belong to new genera described below. Besides P. boppei Lameere, 1912 must be placed in one genus with P. plumicornis Pu, 1987. All studied materials are deposited in IZAS = Institute of Zoology, Chinese Academy of Sciences, Beijing, China.

Type species. Prionus unilamellatus Pu, 1987.
Etymology. The generic name is composed of Unila- (referring to
the antennae with lamellae in one side) and Prionus (the type genus
of the subfamily Prioninae). Gender masculine.
Males: big brown beetles; frons transverse, deeply concave, eyes
big, finely granulated, strongly emarginated; the distance between dorsal eye lobes smaller than width of 1st antennal joint; temples narrow, narrower than eyes, parallelsided; genae very short, about as wide as width of apical joint of maxillary palpi, palpi light brown, slightly longer than mandibles; apical palpal joints elongated, considerably widened distally.
Antennae long, scarcely shorter than body, 13-jointed; 1st joint thick, coarsely, densely granulated, about 1.5 times as long as wide; 2nd joint transverse, 1.5 times as wide as long; 3rd joint is the longest, about twice length of 1st, basal parts of 4th and 5th joints about as long as 1st joint; further distal joints shorter; 3rd joint with rasp-shaped surface, its outer angle attenuated in a short sharpened plate; joints 4-12 with short flat lamellae, each lamella slightly longer than basal part of corresponding joint; cuticula of 4th-5th joints granulated, big granules sharpened; cuticula of further distal joints striated.
Prothorax transverse, its basal width about 2 times of its length; anterior and middle lateral thoracic spines long and narrow, middle spine much longer than anterior; posterior thoracic angles triangularly attenuated, without distinct spines; pronotum strongly depressed, its anterior and posterior borders banded and raised; anterior border straight, convex at middle; posterior border triangularly projected; pronotal surface covered by long erect setae, with irregular dense coarse punctation and 4 low tubercles, with short central ridge, which transformed posteriorly in a short furrow; ventral thoracic process convex, slightly widened distally; scutellum round, about as long as wide.
Elytra about 2.1 times as long as basal width, lusterless, with very fine sculpture, widest near middle, gradually attenuated behind middle, rounded along outer apical margin, with short distinct spines at internal angles; elytral costae hardly pronounced; metepisternum and metasternum with long erect dense setae.
Legs long and thin; tarsi narrow; 1st tarsal joint about as long as 2nd and 3rd combined and subequal in length to apical joint; lobes of 3rd joints angulated but not attenuated in spines; 1st-3rd joints with well developed wide pads, totally covering ventral surfaces; each pad with distinct shining central line.
Abdomen shining, partly covered with long pubescence; erect
setae of first visible abdominal segment rather dense; setae of 2nd segment are concentrated near middle and diminished laterally; pubescence of other segments rather sparse and short; last sternite deeply emarginated; pygidium and postpygidium with very small emarginations.
Female: large-sized black beetle; frons transverse, deeply concave, eyes smaller, finely granulated, slightly emarginated; the distance between dorsal eye lobes bigger than width of 1st antennal joint; temples narrow, narrower than eyes, less converging posteriorly; genae very short, about as wide as width of apical joint of maxillary palpi; palpi brown, longer than mandibles; apical palpal joints elongated, not dilated apically.
Antennae short, not reaching elytral middle, 13-jointed; 1st joint thick, with small sparse irregular punctation, about 2 times longer than wide; 2nd joint transverse, about 1.5 times as wide as long; 3rd joint is the longest, about 1.5 times as long as 1st, without process, but slightly angulated apically; basal parts of 4th and 5th joints about as long as 1st joint; further distal joints shorter; joints 412 with short flat lamellae, each lamella shorter than basal part of corresponding joint, except joints 9-11 with lamellae subequal to basal part of corresponding joint; cuticula of 4th-5th joints granulated; cuticula of further distal joints striated.
Prothorax transverse, its basal width about 2 times of the length; three lateral thoracic spines are well developed; middle spine much longer than anterior and posterior spines; pronotum strongly depressed, its anterior and posterior borders banded and raised; anterior border straight, convex at middle; posterior border triangularly projected; pronotal surface covered by long erect setae, with irregular dense coarse punctation and 4 low tubercles, with short central ridge, which transformed posteriorly in a short furrow; ventral thoracic process convex, slightly widened distally; scutellum round, about as long as wide..
Elytra about 2.5 times as long as basal width, with very fine sculpture, widest near middle, gradually attenuated behind middle, rounded along outer apical margin, with short distinct spines at internal angles; elytral costae hardly pronounced; metepisternum and metasternum with long erect but sparse setae; wings well developed.
Legs long and thin; tarsi narrow; 1st tarsal joint about as long
as 2nd and 3rd combined and subequal in length to apical joint; lobes of 3rd joints angulated but not attenuated in spines; 1st-3rd joints with well developed wide pads, totally covering ventral surfaces; each pad with distinct shining cental line.
Abdomen shining, partly covered with long pubescence; erect setae of first visible abdominal segment rather dense; setae of 2nd segment are concentrated near middle and diminished laterally; pubescence of other segments rather sparse and short; last sternite deeply emarginated; pygidium and postpygidium with very small emarginations.
Discussion. The genus seems to be similar to Lobarthron Semenov, 1900 by formal characters: antennal joints are not numerous (12 in Lobarthron), most of joints with flat lamellae (3rd-11th in Lobarthron); anterior and middle thoracic spines well developed (sometimes poorly developed in Lobarthron), metathorax with long, dense setae; but in fact two genera are not relatives because: in Lobarthron basal parts of antennal joints are relatively shorter, and lamellae are relatively longer; pronotum is strongly convex, glabrous, shining; lobes of tarsi joints attenuated in spines; pads of tarsi joints narrow, with wide shining line along middle of each joint; wings in females are partly reduced.
Pogonarthron (s. str.) Semenov, 1900 also has most of antennal joints with a single long lamellae each, but in Pogonarthron antennal joints are numerous, from 20 to 26 joints in each antenna; anterior lateral thoracic spines reduced, pronotum convex, tarsi joints with spined lobes.
Only the type species is combined in this genus:

Abdomen shining, totally glabrous; last sternite and tergite rounded.
Discussion. The genus seems to be similar to Pogonarthron (Multicladum Danilevsky in Danilevsky & Komiya, 2014) by formal male characters - females of P. (Multicladum) are unknown: antennal joints in Pogonarthron are also numerous - 22-25 in P. (Multicladum), most of antennal joints in P. (Multicladum) with bilobed lamellae - from 5 th to the apex, but apical joint here with several lamellae; anterior and posterior thoracic angles in Pogonarthron without spines, metathorax with long, dense setae; but in fact two genera are not relatives because: pronotum in Pogonarthron never shining, with coarse sculpture and densely pubescent; 3rd and 4th antennal joints in P. (Multicladum) without lamellae; lobes of tarsi joints in Pogonarthron with long spines; pads
of tarsi joints in Pogonarthron very narrow, with wide shining line along middle of each joint, females of P. (Multicladum) must be with reduced wings.
Two species are combined in this genus:
