species
By G. .4.. ANUFRTEV (Gorky Slate Lnilersily)
In the Soviet Far East the genus Onco;r.sis Buuneister, 183E is represented Lry a great number of species nranl' of rvhich are apparently endemics. Be- cause of the extensiye individual varialion it is often difficult to identify some
of the species on exlernal characters alone. The male genitalia, however, offer good specific characlers.
The following is a description of one new subgenus and seven new species
of leafhoppers of the genus which have been found in the Soyiet I.ar East.
.{ key of all wellknou'n Palaearctic species is also given. All species live on trees of the Betulaceae famill'.
The types of new species, rs well as the rest of the material here lreated are in the author's collection aud in the collection of the Leningrad Zoological Research lnstilute.
Subgenus Sispocrris nov.
Tvpe of subgenus BUthoscopus jugTlcns \Iatsumura, 1912 (F'igs. l-8).
Differs principally from Oncopsis s. str. in the follorn'ing characters: py- gofer with strong spine on dorsal side: aedeagus with unpared teeth on sides
nerr the top and with two pairs of teeth on ventral side; appendage of anal ttrbc rvith underdeveloped branches.
Subgenus Oncoptit t. str.
The species of the subgenus Oncopsis s. slr. are forming two groups. The representatives of the first group have an aedeagus with a saddle-concaved dorsal margin. Three Palaearctic lO. llaoicollis (Linnaeus, 1758), O. sub- angulata (J. Sahlberg, 1E7l) and O. carpini (J. Sahlberg, lETl)l and all
knortr'n Nearctic species [O. sobrias (Walker. 185f), O- minor (Filch, 1851), O. nigrinasi (Fitch, 1851), O. coloraclensis iBaker, 1898) and O. uariabilis (Fitch, 1851)l belong to this group. The representatives of the second group

Oncopsis (s. str. ) (drrstrr sp. n. {FiBs. 20-22)
Crown is black. Face is yellow with black band between ocelli. This band is connected with the black field on the crown by a middle black stripe.
Pronotum is brownish-jet-black rvilh a more pale posterior margin. Sculellum is black. Palecoloured specimens have yellos-brorvn pronotum with black spots on anterior margin. Forewings are black with transparent bordering of claval suture, wilh lransparent costal margin and with more or less visible transparent band on subapical cells. Clavus black, apical cells dark, veins are bordered with black.
The male genital segment is rer)- characteristic. -{edeagus as in O. (Ini
(Shrank, 1801), i.e. with convex dorsal margin. Stilus gradually widening to apex. Appendage of anal segment with one strong unbranched process, Iurned to ventral side. No one of known species has such r process.
Length of the bodv 4.55-5.05 mm.

Oncopsis (s. str.) ccliginos( sp. n. (Figs.23-25)
General appearance:rnd colour is like previous species. It is distinguished by larger size, pale basis of clavus, more rvide and pale costal margin and more wide and pale bordering of claval suture.
It is rvell distinguished from previous and other well-known species by structure of anal tube appendage. Penis as in O. (lni convex all the wa]' along dorsal margin. Stilus with approximately parallel sides. .{nal tube
appendage with two branches
- ventral and dorsal. \'entral branch is semicircularly bent dorsad; it is broadened or sligthly bifurcated at the end.
Dorsal branch of appendage is short, subparallel lo apical part of lhe ventral one. O. obstructo Dlabola, 1963. has someu'hat similar anal tube appendage, but it is of another general appearance and has a \yell-distinguishable stilus rvith dorsal part sharply broadened.
Length of the body 5- 4 mm.

Oncopsis (s. str.l discrepuns sp. n. (Figs. 28-29)
Crown is black. Face yellow with black band near cephalic margin and
\yilh black spots along frontoclypeal sides. The band and the spots may be merged, forming a black triangular area around frontal margin. Pronoturn bro\yn to black with lighter posterior margin. Scutellum brownish-black.
