Type
species.
Alebroides ussurica
Vilbaste, 1968
, by original designation.
Redescription.
Body robust. Head narrower and distinctly shorter than pronotum (
Fig. 57
). Vertex short, roundly produced anteriorly, in dorsal view shorter than width between eyes, anterior and posterior margins not parallel, coronal suture long and distinct (
Fig. 57
), profile of transition vertex to face rounded (
Fig. 58
). Face short and convex, lateral frontal suture present (
Figs 58, 59
). Forewing long and narrow, apical cells occupying less than third its length, veins
RP
and MP’ confluent for short distance at their bases, both arise from r cell and MP”+CuA’ from m cell, c, r and m cells almost equal in width, all narrower than cua cell, 2nd apical cell subparallel but slightly broadened at apex (
Fig. 60
); hindwing with vein CuA branched apically (
Fig. 61
).
Abdominal sternal apodemes developed and parallel sided (
Fig. 70
). Male pygofer elongate, strongly narrowing caudad, caudodorsal angle of lobe bent caudodorsad and with few rigid microsetae terminally, ventral appendage absent (
Figs 62, 64
); dorsal bridge short (
Fig. 63
). Subgenital plate much exceeding pygofer side, broad at base and gradually tapering towards apex, with rigid microsetae in basal group, lateral macrosetae numerous reaching apex of plate (
Figs 62, 66
). Paramere robust, distal teeth densely grouped and fine setae situated more cephalad (
Fig. 68
). Aedeagus slender, hook-shaped in outline, without preatrium and dorsal apodeme, shaft tubular, in lateral view slightly tapering distally, gonopore apical (
Figs 62, 67
). Connective with lateral margins straight or evenly concave, anterior margin incised medially. Anal tube process strongly narrowing apically and curving mesad.
Remarks.
Schizandrasca
Anufriev
is similar to
Alebroides
Matsumura
,
Apheliona
Kirkaldy
,
Nikkotettix
Matsumura
,
Ghauriana
Thapa
,
Matsumurama
Thapa
,
Bhatasca
Dworakowska
and
Luodianasca
Qin & Zhang
in having the veins MP’ and
RP
in forewing arising from m cell and CuA in hindwing branched apically. However,
Schizandrasca
differs from these genera in having the aedeagus slender, hook-shaped in outline and without a preatrium, from
Alebroides
,
Apheliona
,
Ghauriana
and
Matsumurama
in lacking the ventral pygofer appendage, from
Luodianasca
in having the abdominal sternal apodemes developed and the subgenital plate with setae in the basal group, from
Bhatasca
in having a well-developed anal tube process in profile and from
Nikkotettix
in having the caudodorsal angle of the pygofer lobe bent caudodorsad and the paramere bearing small teeth densely grouped apically.
Schizandrasca
also differs from
Bhatasca
and
Luodianasca
in having the macrosetae of the subgenital plate arranged in two rows medially.
Included taxa:
Schizandrasca rubrifrons
(
Matsumura, 1931
)
and
Schizandrasca ussurica
Vilbaste (1968)
.
Distribution.
China
(Hubei and Shaanxi Provinces), Far East of
Russia
,
Korea
.
Dworakowska (1982)
studied the
types
of
Empoasca rubrifrons
Matsumura (1931)
and transferred it to
Schizandrasca
Anufriev (1972)
. However,
Empoasca rubrifrons
Matsumura
was described based on two female specimens without distinct diagnoses, we think the status of
Schizandrasca rubrifrons
(
Matsumura, 1931
)
will need to be reconsidered once more material becomes available.
